Abstract:

The objective of this research was to investigate dental bridges with and without implants. Threedimensional (3D) mandible models were reconstructed by computer tomography (CT) to simulate biting behaviors. The dental implant is an important factor in dental bridge applications. Several studies have investigated finite element models for dental implants; however, few have examined a model for dental bridge with implant. The results revealed that stress was significantly increased when dental bridge was used with implant. Moreover, the dental bridge with implant group demonstrated a relatively big stress in mandible, which was 4.01% lower compared with that of the control group. Dental bridge would be an effective means of recovering dental performance. However, the present research stated that the implant of dental bridge has a potential to increase abnormal stress, and uniformly distributing stress in the dental bridges.

Abstract:

Objectives The aim of this study was to demonstrate the clinical applicability of limited cone beam computed tomography (Dental 3D-CT) for assessment of bone-grafted alveolar cleft. Patients and Methods Seventeen bone bridges were examined after alveolar bone grafting in 13 patients with cleft lip and palate. All bone bridges, including cleft-adjacent teeth, were examined by plain radiography and the Dental 3D-CT imaging system. Results The plain radiographs showed the approximate condition of the bone bridge and cleft-adjacent teeth. The Dental 3D-CT images clearly showed precise three-dimensional (3D) morphology of the bone bridge, 3D relationships between the bone bridge and the roots of cleft-adjacent teeth, and their periodontal condition. In addition, the conditions surrounding dental implants installed in the bone bridge could be observed three-dimensionally. Conclusions The results indicate that the Dental 3D-CT imaging system is suitable for clinical assessment of alveolar bone grafting before and after installation of dental implants or orthodontic treatment of the cleft-adjacent teeth.

Abstract:

Abstract Elderly people suffer from more and more teeth problems. The tooth-implant-supported prosthesis provides a reliable solution to missing teeth patients. The proper dental prosthesis design to prevent overstress is essential due to the mechanical characteristics of the dental bridge abutments are different. The finite element method is widely applied, but proper experimental validation is required. The curing shrinkage epoxy is applied for the photoelasticity measurement because its mechanical property is close to the cancellous bone. A series of process developments, including mold design, residual stress releasing and artificial soft film making, is accomplished in this research to simulate the mechanical response of dental bridges in practice. The process is proven and can be accomplished at the dentist's workshop. The transmission photoelasticity technique is applied to measure the residual stress distribution and it nondestructively provides the continuous improvement guideline. The model-making procedure and tools are proven to be available at the dental workshop. Following the model-making procedure, the dental bridge model shows a low residual stress level that the photoelasticity system cannot detect. Excellent reproducibility of the proposed procedure has been validated. These models exhibit stable maximum stress of 2.13 MPa around the natural tooth apex and apical implant region when a 300 N vertical loading is applied upon the dental bridge. Finally, a finite element model of the dental bridge, including the natural tooth and dental implant, is built and validated by the photoelastic measurement.

Abstract:

The number of supporting dental implants is an important criterion for the surgical outcome of dental bridge fixation, which has considerable impact on biomechanical load transfer characteristics. Excessive stress at the bone–implant interface by masticatory loading may result in implant failure. The aim of this study was to evaluate the impact of the number of implants supporting the dental bridge on stress in neighboring tissues around the implants. Results of the study will provide useful information on appropriate surgical techniques for dental bridge fixation. In this study, osseointegrated smooth cylindrical dental implants of same diameter and length were numerically analyzed, using three-dimensional bone–implant models. The effect of the number of supporting implants on biomechanical stability of dental bridge was examined, using two, three and four supporting implants. All materials were assumed to be linearly elastic and isotropic. Masticatory load was applied in coron-apical direction on the external part of dental bridge. Finite Element (FE) analyses were run to solve for von Mises stress. Maximum von Mises stresses were located in the cervical line of cortical bone around dental implants. Peak von Mises stress values decreased with an increase in the number of implants that support the dental bridge. Results of this study demonstrate the importance of using the correct number of supporting implants to for dental bridge fixation.

Abstract:

FEM studies were made on a zirconia dental bridge of 4 elements with supports on 2.4 and 2.7, and edentation on 2.5 and 2.6. Appling a compressive force of 350N on Z direction, quite normal for mastication, was analyzed the behavior of the dental bridge. Zirconia, although having a high mechanical strength, is fragile when rotation or bending movements occur. The analysis reveals some bridge deficiencies, which may be due either to inaccuracies in the prosthetic abutment construction (especially in relation to their inclination), to the technique of realization or to insufficient dental support. In our study, the most vulnerable elements are the crowns on teeth 2.4 and 2.7. Finite element analysis, highlighting possible structural and design deficiencies, may be a solution to improve dental bridges. The only disadvantage of the finite element analysis that was performed before the actual restoration is related to the fact that performing the simulations involves a time-consuming phase.

Abstract:

The aim of the present research was to evaluate the biomechanics of dental bridge with and without implant. Oral models were reconstructed by 3D computer tomography images to simulate oral environment. The stress is an important role in dental bridge applications for osseointegration. Many studies have investigated finite element researches for dental implants; however, few have evaluated a model for dental bridge with and without implant. The results revealed that abnormal focusing stress was found when dental bridge was used with implant. Moreover, the unbalance situation was found on the model with only one implant, the highest stress appeared in the present group. Dental bridge with implants would be an effective means of recovering dental performance. However, the present study showed that if only one pier with dental implant in bridge treatment has a potential to increase abnormal stress, and uniformly distributing stress.

Abstract:

Inlay-retained dental bridges can be a viable minimally invasive alternative when patients reject the idea of implant therapy or conventional retained full-coverage fixed dental prostheses, which require more tooth preparation. Inlay-retained dental bridges are indicated in patients with good oral hygiene, low susceptibility to caries, and a minimum coronal tooth height of 5 mm. The present study aims to evaluate, through the finite element method (FEM), the stability of these types of dental bridges and the stresses on the supporting teeth, under the action of masticatory forces. The analysis revealed the distribution of the load on the bridge elements and on the retainers, highlighting the areas of maximum pressure. The results of our study demonstrate that the stress determined by the loading force cannot cause damage to the prosthetic device or to abutment teeth. Thus, it can be considered an optimal economical solution for treating class III Kennedy edentation in young patients or as a provisional pre-implant rehabilitation option. However, special attention must be paid to its design, especially in the connection area between the bridge elements, because the connectors and the retainers represent the weakest parts.

Abstract:

Ceramics have rapidly emerged as one of the major dental biomaterials in prosthodontics due to exceptional aesthetics and outstanding biocompatibility. However, a challenging aspect remaining is its higher failure rate due to brittleness, which has to a certain extent prevented the ceramics from fully replacing metals in such major dental restorations as multi-unit bridges. This paper aims at simulating the crack initiation and propagation in dental bridge. Unlike the existing studies with prescriptions of initial cracks, the numerical model presented herein will predict the progressive damage in the bridge structure which precedes crack initiation. This will then be followed by automatic crack insertion and subsequent crack growth within a continuum to discrete framework. It is found that the numerical simulation correlates well to the clinical and laboratory observations.

Abstract:

Evolutionary Structural Optimisation (ESO) is a relatively new design tool used to improve and optimise the design of structures. It is a heuristic method where a few elements of an initial design domain of finite elements are iteratively removed. Such a process is carried out repeatedly until an optimum design is achieved, or until a desired given area or volume is reached. There have been many contributions to the ESO procedure since its conception back in 1992. For example, a provision known as Bi-Directional ESO (BESO) has now been incorporated where elements may not only be removed, but added. Also, rather than deal with elements where they are either present or not, the designer now has the option to change the element's properties in a progressive fashion. This includes the modulus of elasticity, the density of the material and the thickness of plate elements, and is known as Morphing ESO. In addition to the algorithmic aspects of ESO, a large preference exists to optimise a structure based on a selection of criteria for various physical processes. Such examples include stress minimisation, buckling and electromagnetic problems. In a changing world that demands the enhancement of design tools and methods that incorporate optimisation, the development of methods like ESO to accommodate this demand is called for. It is this demand that this thesis seeks to satisfy. This thesis develops and examines the concept of multicriteria optimisation in the ESO process. Taking into account the optimisation of numerous criteria simultaneously, Multicriteria ESO allows a more realistic and accurate approach to optimising a model in any given environment. Two traditional methods � the Weighting method and the Global Criterion (Min-max) method have been used, as has two unconventional methods � the Logical AND method and the Logical OR method. These four methods have been examined for different combinations of Finite Element Analysis (FEA) solver types. This has included linear static FEA solver, the natural frequency FEA solver and a recently developed inertia FE solver. Mean compliance minimisation (stiffness maximisation), frequency maximisation and moment of inertia maximisation are an assortment of the specific objectives incorporated. Such a study has provided a platform to use many other criteria and multiple combinations of criteria. In extending the features of ESO, and hence its practical capabilities as a design tool, the creation of another optimisation method based on ESO has been ushered in. This method concerns the betterment of the bending and rotational performance of cross-sectional areas and is known as Evolutionary Moment of Inertia Optimisation (EMIO). Again founded upon a domain of finite elements, the EMIO method seeks to either minimise or maximise the rectangular, product and polar moments of inertia. This dissertation then goes one step further to include the EMIO method as one of the objectives considered in Multicriteria ESO as mentioned above. Most structures, (if not all) in reality are not homogenous as assumed by many structural optimisation methods. In fact, many structures (particularly biological ones) are composed of different materials or the same material with continually varying properties. In this thesis, a new feature called Constant Width Layer (CWL) ESO is developed, in which a distinct layer of material evolves with the developing boundary. During the optimisation process, the width of the outer surrounding material remains constant and is defined by the user. Finally, in verifying its usefulness to the practical aspect of design, the work presented herein applies the CWL ESO and the ESO methods to two dental case studies. They concern the optimisation of an anterior (front of the mouth) ceramic dental bridge and the optimisation of a posterior (back of the mouth) ceramic dental bridge. Comparisons of these optimised models are then made to those developed by other methods.

Abstract:

Objetivo: Avaliar pacientes reabilitados com prótese tipo protocolo mandibular e analisar o impacto do diferente número de implantes utilizados na taxa de sobrevivência dos implantes, perda óssea marginal e sobrevivência das próteses. Material e métodos: Esta revisão sistemática foi conduzida segundo orientações do PRISMA e registrada sob número de registo CRD42016048523 (PROSPERO). A base de dados electrônica PubMed/MEDLINE foi pesquisada para artigos publicados até 17 de julho de 2016 sem restrições quanto ao ano de publicação e teve como objetivo responder a seguinte pergunta em formato PICO: "Em pacientes desdentados, protocolos mandibulares suportados por três implantes, comparados com diferente número de implantes, mostram taxa de sobrevivência de implantes, perda óssea marginal e sobrevivência da prótese satisfatórios?" Os estudos foram avaliados segundo os níveis de evidência OCEBM e a qualidade metodológica foi avaliada de acordo com a escala MINORS e ferramenta de risco de viés Cochrane. Foi realizada a estatística descritiva quando aplicável. Curvas de sobrevivência para os implantes foram construídas com o metódo de Kaplan Meyer e a perda óssea marginal foi analisada pelos testes de kruskal-Wallis, Dunn’s e Mann Whitney. Resultados: 21 estudos foram incluídos na síntese quantitativa. 4712 implantes e 1245 protocolos mandibulares foram examinados em 1245 pacientes. Os resultados foram agrupados em categorias com base no número de implantes instalados em cada paciente: grupo 1 (três implantes) mostrou uma taxa de sobrevivência do implante de 90%, grupo 2 (4 implantes) apresentou 95% e o grupo 3 (cinco implantes) atingiu a menor taxa de sobrevivência do implante (74%). Os grupos 1 e 3 apresentaram os menores valores de perda óssea no primeiro ano (0,73 e 0,70 mm respectivamente), com diferença estatisticamente significante do grupo 2 que registrou mediana = 1,31 mm (p = < 0,001). Conclusão: Apesar das limitações quanto à falta de estudos de elevado nível de evidência e da própria metodologia da pesquisa por termos MeSH, pôde-se concluir que protocolos mandibulares suportados por três implantes demonstraram sobrevivência de implantes e perda óssea marginal no primeiro ano satisfatórios. A sobrevivência de próteses, no entanto, foi inferior aos demais grupos e isto sugere um maior acompanhamento de tais reabilitações a fim de esclarecer dados e buscar soluções.
Purpose: To assess edentulous patients rehabilitated by implant-supported mandibular full-arch bridges and to analyze the impact of the different number of implants used on implant survival rate, bone loss around the fixtures and prosthesis survival rate. Material and methods: This systematic review followed PRISMA guidelines and was registered on PROSPERO (registration number CRD42016048523). PubMed/MEDLINE electronic database was searched for articles published up until July 17th, 2016 without restrictions about publication year and aimed to answer the following question in PICO format: “In edentulous patients, full arch-bridges supported by three implants, compared to those with different number of implants, show satisfactory implant survival rate, bone loss and prosthesis survival rate?” Evidence level of studies were evaluated according to OCEBM e the methodological quality by MINORS scale and Cochrane Risk of Bias Tool. Descriptive statistics was performed when applicable. Implant survival curves were constructed with Kaplan-meyer method and marginal bone loss was analyzed with kruskal-Wallis, Dunn’s and Mann Whitney tests. Results: 21 studies were enrolled. Overall, 4712 implants and 1245 implant-supported fullarch bridges were examined in 1245 patients. Results were grouped on categories based on the number of fixtures on each patient: Group 1 (three implants) showed an implant survival rate of 90%, Group 2 (four implants) presented 95% and the Group 3 (five implants) reached the lowest implant survival rate (74%). Group 1 and Group 3 showed the lowest values of first year bone loss (0.73 and 0.70 mm respectively), statistically significant different of Group 2 that registered median = 1,31mm (p = <0.001). Conclusion: Despite of the limitations regarding the lack of high level of evidence studies and the methodology of MeSH terms research itself, it was concluded that full archbridges supported by three implants show satisfactory implant survival rate and first year bone loss. The prosthesis survival rate, however, was inferior to the other groups and this suggests a bigger follow-up of these rehabilitations with the aim of clarifying data and search for solutions.

Esse trabalho teve como objetivo principal avaliar a resistência à falha da infraestrutura de uma prótese parcial fixa em zircônia de três elementos e aparafusada sobre implantes, através de análise de tensões por elementos finitos e determinação da resistência à fadiga da estrutura. Como objetivo secundário, foram avaliadas as distribuições das tensões nos demais componentes da prótese. Na análise de tensões, dois modelos distintos foram gerados, sendo o primeiro com prótese, implantes e parafusos similares àqueles adotados na clínica odontológica. Um segundo modelo, usado como controle, adotou uma geometria simplificada. As cargas mastigatórias foram aquelas usuais da literatura especializada e a análise por elementos finitos foi realizada através do programa Ansys Workbench 14.5. Os resultados das distribuições de tensões mostraram semelhanças entre os dois modelos, com pequenas variações relacionadas às geometrias empregadas. As tensões calculadas ficaram abaixo dos limites de resistência mecânica da zircônia e das ligas de titânio. No cálculo da vida em fadiga da prótese de zircônia um modelo analítico foi adotado prevendo uma vida infinita para o componente.
The main goal of this work was to evaluate the failure resistance of a zirconia fixed partial denture of three elements screwed on implants by means of a finite element stress analysis and the determination of the fatigue strength of the structure. As a secondary objective, the stress distributions in the other components of the prosthesis were evaluated. In order to promote the stress analysis, two different models were generated, the first making use of prosthesis, implants and screws similar to those adopted in the dental clinic. A second model, used as control, adopted a simplified geometry. The masticatory loads were those presented usually in the literature and finite element analysis was performed making use of Ansys Workbench 14.5 program. The stress distribution results showed similarity in both models, with small variations related to the adopted geometries. The calculated stresses were smaller than the ultimate strength of the zirconia and titanium alloys. Concerning the fatigue life of the zirconia prosthesis an analytical model was adopted and estimated an infinite life for the component.

Abstract:

In August 2003, the United States resumed the sharing of real-time intelligence with Colombia, information that will be used by Colombia to shoot down aircraft engaged in drug trafficking. A similar program with Peru may restart soon. Such operations are part of the Air Bridge Denial Program (ABDP), a program that has been operating since the early 1990s designed to cut off the flow of drug out of the Andean Region of South America.
This thesis examines the history of the ABDP and the norms applicable to shootdown operations under the UN Charter, customary international law, the Chicago Convention, and human rights law to determine the specific limitations of the prohibition. International law generally prohibits the shootdown of international civil aircraft, and the nature of the shootdown operations can also have human rights implications.
This thesis then examines the circumstances under which international law would excuse an otherwise unlawful shootdown of a civil aircraft. Self-defense, the law of armed conflict and distress are ruled out as likely candidates for use in the legal justification of the shootdown of drug aircraft.
The best defense for the conduct of ABDP shootdowns is the defense of necessity as it exists under customary international law. The potential harm to the essential interests of States threatened by drug trafficking combined with the unique nature of the drug trade in the Andean Region is the ideal situation for the invocation of necessity and provides the most sound international legal justification for the conduct of shootdown operations in this context.

Abstract:

This study examined personality characteristics of dental students at Faculty of Dentistry at Kuwait University and investigated the relationships between personality characteristics of these students and their preferred teaching methods. In order to assess personality characteristics, The Myers-Briggs Type Inventory (MBTI) was used. For teaching method categorization Grasha’s (2002) classification was used. This research builds knowledge about personality traits as measured by the Myers-Briggs Type Inventory® of dental students in Kuwait. Further, it adds knowledge about teaching methods preferred by dental students. Two surveys, the Myers- Briggs Type Indicator® Form M and a brief learning preference for teaching methodology survey, served as data collection instruments. Twenty-seven out of 43 dental students were interested in participation. Twenty-three (53.4%) students completed both surveys. After the data were analyzed, no dominant personality types among the dental students surveyed was uncovered. There were, however, four types slightly more represented than others. This study did find some correlations between certain subgroups and preferences for teaching methods. The study also found that students perceived Hybrid and Demonstrator methods as both the most preferred and most beneficial. Overall, the findings support that there is association between personality and preferences of teaching method and there is a preference of a teaching method over the other in dental education in general.

Abstract:

Dos motivos impulsaron este libro: 1. los maestros dedican poco tiempo a reflexionar y organizar sistemáticamente su misma experiencia pedagógica, a leer a otros colegas, a escribir, lo cual hace que pierdan posibilidades valiosas para crear nuevas formas de enseñanza y aprendizaje. 2. La necesidad de aportar dentro y fuera de la universidad un material que pueda ser referente en el trabajo pedagógico de las carreras de pregrado relacionadas con la educación, que favorezca ese diálogo de saberes entre maestros y maestros-estudiantes, y que brinde la posibilidad de leer-se-nos. En suma, esta publicación abre otro camino a la comprensión, a la reflexión y a la acción sobre la práctica y la experiencia pedagógicas como claves del saber pedagógico.

Abstract:

AbstractThe Maker Movement, which has for years received much attention, still presents many economic, social and educational implications that are ripe for investigation. The movement’s community of practice can be defined as “a knowledge-building community” (Scardamalia and Bereiter, The Cambridge handbook of the learning sciences, pp 97–115, 2006) as cited in Martin (Martin, J Pre-Coll Eng Educ Res (J-PEER) 5(1):4, 36 2015). This apt definition, which refers to the hyper complex, connected society that engendered it, opens up new possibilities in the field of education. The main goal of this reflective paper is linked to the creation of a theoretical framework that could explain and support the movement’s background. This will lead to an analysis of three different pedagogical models (Célestin Freinet, Loris Malaguzzi, Bruno Munari) that have much in common with the Maker Movement. We focused our study on the most positive traits of makers: social inclusion, democracy and the failure-positive/collaborative approach. Considering the importance of the European Union’s Key Competences, our aim was to create a bridge between the “maker mindset” (Dougherty, Design, make, play, pp 9, 25–29, 2013) and these competences, in order to consider the possibility of introducing the movement into the national curriculum. The point of contact between the two can be the basis for promoting active citizenship, grounded, naturally, in the Key Competences. Subsequently, to test our analysis in the first part of our reflection, we look at the experience of DENSA (Developing Edutainment for New Skills and Attitudes) Coop. Soc.

Abstract:

Presently, dental implantations are the ideal solution and best substitute option for missing teeth. Dental implants determined the replacements of root and non-working teeth after the loss of natural teeth. Strengthening dental materials helps to fix the loss teeth. For teeth with root disease and fault in bone density, dental implantation is very essential. While bridge work and dentures decline to reclaim the suitable chewing condition and turn the problem of missing teeth, dental implants trace the solution of missing teeth. For more progress in dental-concerned technology, an extensive growth in dental implants has been noticed during the last several years. So there is a large need of excellent, quality dental materials. The selection of the implant materials, their generation system, manufacturing method, age-long durability, bio compatibility with medical principle, and professional dental field of study are therefore essential.

Abstract:

Normal healing procedure of bone involves various sequential events to develop bone and bridge the bone -to- bone gap. When this healing occurs with a metal (titanium) fixture on one side, it is called as osseointegration. After extensive studies on this topic, it is found that this procedure occurs in presence of various biologic constituents that are spontaneously released at the site. Thus, to accelerate normal healing after implant placement and make results more predictable, it has been proposed to use these autologous factors in the osteotomy site. Since it is the beginning of a new revolution in dental implantology, right now it is essential to analyze all possible combinations of host conditions, bone quality and quantity and bio factors being used. This can definitely be a boon for the patients with compromised systemic or local conditions.

Abstract:

Poor oral health afflicts many low-income and other vulnerable populations. Lack of access to oral health can lead to unnecessary tooth decay, periodontal disease, pain, and the advancement of oral cancer. The absence of preventive care often leads to unnecessary and expensive visits to hospital-based emergency departments to address the pain of dental disease but not the causal conditions. The consequences on inequitable access to dental care are significant for individuals, families and communities. The OHICAN pilot project looked to address the lack of equitable access to care by creating new points of access, training medical providers to perform oral exams and apply fluoride when indicated, thus increasing the oral health workforce, utilizing technology to bridge clinical practice, education, training and research, educating stakeholders to allow dental hygienists to provide preventive care under general supervision, and creating business models that will assist others who seek to create a dental home for those they serve. Social, political and economic forces all contribute to varying degrees in terms of equity in healthcare. The work of OHICAN was designed to create a blueprint for potential solutions to these issues in order to foster oral health equity. Changes to improve access to dental care can take place in a relatively short period of time when all who care and are impacted by this continued unmet oral health need work together.

Abstract:

This chapter introduces the scope of the book—bioMIMETICS can be described as an innovative form of technology that imitates (or mimics) nature in order to improve human lives via creating desirable solutions. It is the study of nature and natural phenomena, principles, and underlying mechanisms, to obtain bio-inspired that may benefit various applied scientific and technological disciplines. Smart/Intelligent nano-bioMaterials for Tissue Engineering and Regenerative Medicine are a fine example. Yet, biomimicry can go above and beyond the simplistic inspiration and use of natural properties as the basis for innovation of new products. It bridges the gap between the lab and the industry, via the intra-disciplinary design and formulation of functional solutions combining knowledge, methods, techniques, and advances in the fields of chemistry, biology, architecture, engineering, medicine, pharmaceutics, dentistry, and biomedical engineering. Three-Dimensional Printing, Hybrid nanoCoatings, and Stimuli-sensitive and -responsive Cell/Drug Delivery Systems, and Robotics are some of the topics covered in this new book. In this first chapter, a general overview of bio-inspired materials, technologies, and strategies, collectively known as “bioMiMETICS,” is presented to bridge the gap between the laboratory “bench-top” and translational application, particularly, the clinic or “bed-/chair-side,” with a focus on “REGENERATIVE DENTISTRY” and the “CRANIO-MAXILLO-FACIAL bio-COMPLEX.”

Abstract Recent advances in dental bridge construction have included the use of composite fiber resins. These composites are less expensive and easier to utilize in bridge fabrication than the common system of metal with porcelain cladding. The effects of varying the percentage of fiber-reinforced material and geometry of the internal bridge design are of great interest. Finite Element Analysis (FEA) methods show promise in the evaluation of fiber behavior within these bridges, along with bridge design.

Abstract:

Mechanical fracture is a common cause of failure for 3-unit dental bridges, particularly, the all-ceramic structures. The purpose of the present study was to evaluate the effect of convergence angles of the abutments on the distribution of the mechanical stresses, within the prosthesis and at the restoration-abutments interface of a 3-unit all-ceramic bridge. The 3-D geometrical data of the second premolar and first and second molar teeth were obtained using ATOS scanner system and utilized for reconstruction of a surface model of the 3-unit bridge in I-Deas as solid modeler software. This was then transferred to MSC/Nastran software for mesh generation and finite element analysis. Two FE models were developed with different convergence angles, including 171900 and 168700 tetrahedral solid four-node elements. The models were subjected to two different prosthesis material and three different load cases. Therefore, twelve cases were analyzed and compared. Aforementioned comparing indicated that the maximum tensile stresses occur on the gingival surface of the second premolar retainer, and at the tooth/restoration interface on the marginal distal surface of the second molar. The peak tensile stress was relatively lower for the model with the higher convergence angles but the difference was not significant. Changing the prosthesis material from IE2 to Dicor decreased the stresses within the prosthesis; however, the safety factor was still higher for IE2 due to its higher mechanical strength. The load condition found to have an important role in the mechanical stresses observed.

Abstract:

Pretoria Dental Laboratory (PDL), established in 1992, specialises in three disciplines, namely Crown and Bridge, Prosthodontics and Orthodontics. PDL represents an interesting entrepreneurial opportunity exploitation case because of its rapid expansion over a relatively short time span of 16 years moving from a stable but small laboratory to one of the biggest dental laboratories in the Tshwane Metropolitan area of South Africa. The purpose of this paper is to outline the theoretical framework and research methodology to be utilised in order to provide insight on how PDL interact with various stakeholders, respond to environmental changes, utilise various capitals (strategic, economic, cultural and social) through a process of business decision making to recognise, prepare and exploit business opportunities in the dental environment of South Africa. The outcome of the research is intended to enlighten entrepreneurialism and its application in a specific specialised environment of South Africa.

Abstract:

Traditional methods of producing dental bars for overdentures involve tedious and time-consuming operations that demand substantial human labor and demanding skills. Though there exist several CAD/CAM systems that have been developed for various dental restorations like bridges, crowns, etc., there exists no commercial CAD/CAM system at present for design and fabrication of dental restorations for missing multiple teeth. In the research described in the present paper, CAD models of dental bars for implant-retained dental restorations were used as input for three types of fabrication processes: rapid prototyping followed by investment casting, CNC milling, and direct digital manufacturing. Details of material and process combinations and results of comparing these three types of processes, including an analysis on dimensional accuracy, are discussed.

Abstract:

A dental articulator is a mechanical device used to simulate the relative position and motion between the upper and lower jaw when testing dental work or dental treatments (implants or bridges). Typically, it can be adjusted to approximate patient-specific jaw kinematics. However, the use of dental articulators is essentially a trial-and-error method in order to fine-tune fit and function of the dental work. In this paper we propose a robotic articulator suitable for reproducing tracked movements of the patient’s jaw. Based on an asymmetric-leg parallel structure, dimensional synthesis is performed to optimize performance over the range of motion typical of the human jaw. The resulting robotic device is expected to improve workflow in the processing of dental implants. Fabrication and testing of a prototype robot is also presented.

Abstract:

Dental cutting tools have traditionally been made using resin-bonded diamonds that have a tendency to breakdown during drilling operations with the consequent loss of diamonds and resin binder into the patient’s mouth. Recent developments in chemical vapor deposition have made it possible to create binderless diamond cutting tools that are useful for machining and drilling enamel, dentine, amalgam, and cast alloys used for crowns and bridges. The paper compares newly developed tools with conventional tools that are used for orthodontic and maxillofacial operations. The reduction in wear using coated diamond tools is significant.

Abstract:

Implant based dental restorations have many advantages over standard removable dentures because using implants can prevent the loss of jawbones, help restore facial features, and enable the patients to get firm bites. A critical step in this kind of restorations is the fabrication of the dental bar on which the denture sits. A dental bar is patient-specific because each patient’s jawbone is unique and the device needs to be conforming to the patient’s gingival surface. The design of a dental bar is crucial to the success of dental restorations. Traditionally, designing a dental bar is a lengthy and laborious process and requires high levels of craftsmanship. There have been attempts to develop CAD/CAM systems towards automating design and fabrication of dental restorations. However, currently available commercial CAD/CAM systems are only capable of making crowns, bridges, copings, onlays and veneers, and they are not capable of making dental restorations involving multiple teeth. The present paper describes a method for computer aided design of a dental bar used in implant based dental restorations. The method starts with a set of digital scan data representing the patient’s gingival surface and generates a CAD model of a dental bar that is ready for fabrication of a physical dental bar.
