Abstract (sommario):

There has been limited use of ceramic materials for all-ceramic posterior bridges. Major reasons are the low strength, the strength scatter, and the time-dependent strength decrease of ceramics due to slow crack growth. The objective of this study was to predict the long-term failure probability and loading capability of all-ceramic bridges (Empress 1, Empress 2, In-Ceram Alumina, and ZrO2) by computational techniques. The lifetimes of different bridge model designs were predicted by means of the NASA post-processor CARES. Bridges made of zirconia showed a very high mechanical long-term reliability. Empress I and InCeram Alumina seem to be insufficient as posterior bridge materials based on this prediction. The lifetime of the all-ceramic bridges can be significantly increased by improving the design in the connector area. We conclude that computational techniques can help to judge a ceramic material and a specific ceramic bridge design with respect to mechanical reliability before clinical use.

Abstract (sommario):

Replacement of missing mandibular central incisor is difficult challenge in esthetic dentistry. Resin bonded bridges or maryland bridges can be considered as a treatment of choice in such conditions, which restore the oral function and esthetic of the patient. Maryland bridge preparation requires minimal preparation of the tooth and the bridge can be attached to the periodontally sound adjacent teeth.The combined use of polyethylene fibre and resin composite help achieve durable and functional result.This case report describes the case of esthetic restoration of a young women with midline spacing of mandibular anterior teeth.

Abstract (sommario):

Ceramic systems have limited long-term fracture resistance, especially when they are used in posterior areas or for fixed partial dentures. The objective of this study was to determine the site of crack initiation and the causes of fracture of clinically failed ceramic fixed partial dentures. Six Empress 2® lithia-disilicate (Li2O·2SiO2)-based veneered bridges and 7 experimental lithia-disilicate-based non-veneered ceramic bridges were retrieved and analyzed. Fractography and fracture mechanics methods were used to estimate the stresses at failure in 6 bridges (50%) whose fracture initiated from the occlusal surface of the connectors. Fracture of 1 non-veneered bridge (8%) initiated within the gingival surface of the connector. Three veneered bridges fractured within the veneer layers. Failure stresses of the all-core fixed partial dentures ranged from 107 to 161 MPa. Failure stresses of the veneered fixed partial dentures ranged from 19 to 68 MPa. We conclude that fracture initiation sites are controlled primarily by contact damage.

Abstract (sommario):

There have been significant changes in restorative dentistry since the first publication of Dental Update 50 years ago. The changes in prosthodontics are described in this article, as are the interactions with the sister disciplines of endodontics and periodontology. Conventional crowns, bridges and dentures were the main ‘tools of the trade’ in the 1970s. Adhesive materials, dental implants and bleaching have allowed a less destructive way of repairing and replacing teeth. Dentists and patients have different attitudes to dentistry today. Technology continues to improve, and how we practice continues to evolve. CPD/Clinical Relevance: Looking back over 50 years of clinical dentistry is useful to see the changes in our day-to-day practice and see the techniques which have passed the test of time.

Abstract (sommario):

Objective: The object of this survey study was to assess the knowledge, attitude and practice of dentists towards resin bonded bridges across Pakistan. Methodology: A cross-sectional survey study was conducted. A self-administered questionnaire was distributed among 500 dentists across Pakistan as a google form through electronic media. The questionnaire had three sections. First two sections had details about purpose of study and demographic details respectively. In the third section knowledge, attitude and practice of the participants were assessed. Knowledge and attitude were scored. Level of knowledge and attitude towards use of RBBs was correlated with other variables. Significance of factors related to RBB success was evaluated as percentages. Results: A total of 162 males (78%) and 128 females (63.1%) had adequate knowledge. Overall, 303 (75.2%) participants were inclined to use the RBB while only 100 (24.8%) were not in the favor of using this treatment. 286 participants (71%) were confident to offer this treatment to their patients however, 85% of them actually employed RBBs for ≤ 20% of their tooth replacements. Lack of skills was considered as a major hindrance to employ RBB treatment followed by the lack of technical support. Conclusion: The results of the study showed that participants are poised in knowledge regarding RBBs but they are reluctant to use this confidently because of lack of practical skills. Modest use of RBB in clinical practice is a question mark and a food for thought. Keywords: Resin Bonded Bridges, Conservative Dentistry, Minimally Invasive Dentistry.

Abstract (sommario):

Porcelain fused to metal (PFM) bridge is the most of treatment that commonly used as a fixed partial dentures. One of the indication for PFM bridge is to replacing the loss of posterior teeth. This case report discussed about the treatment of posterior missing teeth with PFM bridge. Objective: to explain the clinical procedures of PFM bridges to treat the patient with posterior missing teeth. Case report: A 29-years old woman came to prosthodontic clinic in Faculty of Dentistry University of Padjadjaran with chief complaint of right maxillary posterior missing teeth. The treatment planning that have been choosen for this case was the porcelain fused to metal bridge due this excellent characteristic of resistence to mastication force compared with other types of bridge such as all ceramic or all acrylic bridge. Beside that, the aesthetic achievement of this kind of bridges is more excellent than all metal bridges. Disscussion: A spatial analysis, calculation the number of abutment against which used, and selected design bridge very determine the success of this treatment. In addition to that, the clinical procedures consisting of abutment teeth preparation, an accurate impression, and appropriate cementation were needed to get the satisfactory result. Conclusions: The porcelain fused to metal bridge is a appropriate option for posterior missing teeth treatment that fullfil satisfactorical biomechanical and esthetic factors.

Abstract The aim of the current investigation is to evaluate optimal pontic and retainer fiber positions for Polyethylene fiber-reinforced composite (FRC) restorations. In series I notch disc specimens were used to mimic loading cuspal regions of pontics. Four groups (n=15/group; codes A to D) were prepared from Artglass composite. Groups A to C were reinforced with polyethylene fibers, and group D was an unreinforced control. Fibers were positioned either around (A), beneath the notch (B), or at the disc base (C). Specimens were stored in distilled water at 37°C for 24 h before testing to failure (CHS=1mm/min) in a universal testing machine. Mean torque to failure values ranked [P< 0.05; one-way analysis of variance (ANOVA)] as follows A = B > C = D. In series II five groups of three unit bridges (n =5/group; codes A to E) were prepared from Artglass dental composite without (group A) or with (groups B to E) different Connect fiber reinforcement locations/ techniques. Bridges were cemented using 2 bond resin cement to a standardized substructure. After storage, as per series I, bridges were loaded mid-pontic region to failure. One-way ANOVA showed no significant (P=0.08) difference between test groups. The research hypothesis was that notched disc and 3 unit bridge test techniques would discriminate equally between fiber-reinforced specimens and an unreinforced composite control was rejected.

Abstract (sommario):

A clinical trial, concerning 203 resin-bonded bridges (RBBs), was performed for investigation of the influence of retainer-type and cementation materials on the survival of these restorations. The survival rates after a 7.5-year follow-up were 75% for anterior RBBs and 44% for posterior bridges. Etched metal RBBs (E-bridges) were significantly more retentive than perforated RBBs (P-bridges); the survival rates were 78% and 63%, respectively. With respect to the cementation materials, Clearfil F, in combination with E-bridges, had the best overall survival (89%, anterior and posterior). Maxillary anterior RBBs were more susceptible to failure than mandibular anterior RBBs.

Abstract (sommario):

Once an adult tooth is misplaced or lost, a patient may search for its replacement in order to restore his or her esthetics and function. Clinical dentistry, in the last few decades, has remarkably developed and enhanced in accordance with the evolution of scientific disciplines and individual’s requirements and demands. Traditional choices in dentistry for replacing a missing adult tooth involve the demountable partial denture, resin-bonded dental bridges, and full or partial coverage dental bridges. Implants have achieved wide acceptance and demand over time because they have the ability to restore function to almost normal in complete and partially edentulous arches. With considerable studies available, implants are highly admitted as a good treatment choice for the substitution of missing teeth these days. While implants are widely becoming an effective choice for missing tooth replacement, the complications and risks related to them are also progressively appearing.

Abstract (sommario):

ABSTRACT Background: Dental implant and fixed bridges are the common and acceptable means of prosthetic restoration of missing tooth. Although each is a viable treatment option, the implant restoration has definite advantages. A major shortcoming of the fixed bridge is the significant tooth reduction of the abutments. This study aimed to know the reasons that make some dentists choose a dental bridge in the edentulous area with adjacent sound teeth over the implant in cases suitable for implant. Materials and Methods: An observational questionnaire study was conducted between January and May 2022. An online questionnaire was sent to qualified dentists practicing in different cities of Saudi Arabia. Absolute frequencies were used to describe the data. Results: A total of 602 dentists received the questionnaire, and 430 responded, resulting in a response rate of 71.7%. The majority of responders (98%) recommended implant as a first choice to replace missing tooth when both implant and fixed bridge can be used in case of sound abutments. However, they mentioned factors such as cost of treatment, patient wishes, and patient’s medical condition act as an obstacle or difficulty to support their use of the implant in some cases. Conclusions: More efforts should be done to encourage dentists to select appropriate treatment option of proven scientific basis without any bias. Patients should be given more information about the advantages of implant over fixed partial denture and should be motivated. Finally, more support from implant companies should be encouraged as well as more knowledge and skill about implant dentistry should be gives during undergraduate courses.

Abstract (sommario):

Dental bridges are one of the treatments for tooth loss cases. Dental profession students at the Faculty of Dentistry of Universitas Padjadjaran (Unpad) conducted their first dental bridge treatment on patients. Evaluating patient satisfaction is essential to measure the success of treatments provided by dental students. This study aims to determine patient satisfaction with the dental bridges treatment provided by dental professional students at the Prosthodontics Polyclinic in terms of chewing, aesthetics and phonetics function, maintenance of the denture, and psychological aspects. This type of research is descriptive cross-sectional. Eighty-two dental bridges users were selected using total sampling at the Prosthodontic Polyclinic from September 2022 to February 2023 out of a total population of 86 users. The inclusion criteria included male or female patients using PFM or full metal dental bridges in the upper or lower jaw, worn for at least seven days to 6 months after definitive cementation, and made a control visit after the insertion of dental bridges. The instrument used was a modified questionnaire called the Patient Denture Assessment (PDA) and an Indonesian version of PDA (PDA-ID), with 12 modified Likert scale questions given online. The results of the study showed that 86,6% of the respondents were satisfied with masticatory function, 97,6% were satisfied with aesthetics and phonetics, 82,9% were satisfied with the maintenance of the denture, and 93,9% were satisfied with the psychological aspects of the use of dental bridges. Most patients were satisfied with dental bridges regarding chewing, aesthetics and phonetics function, denture maintenance, and psychological aspects.

ABSTRACT Introduction Ever since the introduction of the minimal preparation fixed partial dentures, the major concern of the clinicians has been its longevity. Aims and objective The objective of the present study was to compare the clinical performance of resin bonded cantilever bridges with conventional cantilever bridges for a period of 1 year and to evaluate the periodontal changes of abutment teeth using radio visio graphy. Materials and methods Fourteen patients with missing first or second premolar were selected for the study. The patients were divided into 2 groups, conventional cantilever group and resin bonded cantilever group. Results The results were analyzed using Student's t test and Mann-Whitney U test. The clinical success rate for both the groups was 100%. The amount of bone loss at 6 months for conventional group was 0.11 mm and for resin bonded bridge group was 0.10 mm. The amount of bone loss at 1 year for conventional cantilever group was 0.14 mm and for resin bonded fixed partial denture group was 0.16 mm. There was no statistical difference between both the groups. The results showed that the resin bonded cantilever bridges can be used for the treatment of missing posterior tooth.

Abstract (sommario):

Background: Forensic dentistry identification commonly involves using dental cast models as ante-mortem data. Here, dentists generally send the pictures as well as the dental records. However, in recent times, dentists – especially orthodontists and prosthodontists – are using 3D scanners in view of reducing the space for cast model storage as well as sending the 3D imaging for fabricating clear aligners and other items such as crowns and bridges. This new trend means data transmission and viewing has become more complicated since sophisticated laptops or personal computers are generally required. For more practical use, smartphones would be a better option, meaning various simple ideas for viewing 3D data must be explored. Furthermore, the conclusions must be evaluated in terms of the validity for forensic dentistry use. Purpose: To evaluate a number of smartphone applications that are simple, user friendly, scalable and capable of the measurement and superimposition of 3D imaging data. Review: Standard tessellation language (STL) is one of the 3D scan file formats that is also useful for 3D printing. Recently, several applications for 3D viewing have been made available for iPhones (iOS) and Android-based devices, which are able to view STL files. However, they have all received both positive and negative reviews in terms of various applications, including forensic dentistry, and they thus require further evaluation by forensic odontologists. Conclusion: Each application has advantages and disadvantages; however, in our experience as forensic odontologists, the CAD Assistant, exocad and Adobe Photoshop Mix, which are available for iOS and Android devices, are preferable for forensic dentistry needs

Abstract (sommario):

Objective: Congenitally missing maxillary lateral incisors present challenges to dentists in terms of treatment planning and can negatively affect aesthetics and function in patients. The aim of the present study was to determine the preferred treatment approach of dentists with different specialties. Material and Methods: We carried out a descriptive, cross-sectional study using a questionnaire that was self-administered to 12 specialists in removable prosthodontics, 18 specialists in restorative dentistry, 14 specialists in orthodontics, and 173 registered general dentists. Results: General practitioners (72.7%), prosthodontists (92.9%) and, restorative dentists (80%) preferred prosthodontic replacement of missing maxillary lateral incisors, while orthodontists (57.1%) preferred canine substitution. Most general practitioners (62.7%), prosthodontists (71.4%), and orthodontists (92.9%), as well as many restorative specialists (40%), preferred implant-retained crowns for prosthetic replacement of missing lateral incisors. The dental specialties differed significantly in terms of their preferred modalities for treating children over the age of 12 years. General practitioners (56%) preferred removable partial dentures (RPDs), while a mere 17.2% preferred to carry out no treatment. All prosthodontists (100%) preferred treatment with RPDs. Restorative dentists preferred RPDs and adhesive bridges in equal number (33.3% in each case). Fifty percent of orthodontists treating children with missing lateral incisors preferred RPDs, followed by (28.6%) who preferred canine substitution. Conclusion: Preference varied for several reasons among dentists’ treating both adults and children over 12 years of age. KeywordsMaxillary missing teeth; Dentist's preference; Teeth replacement; Dental implant.

Abstract (sommario):

Background. Monolithic zirconia is an emerging material for crowns and bridges. The possibility of full digital design has made it an attractive alternative material for implant-supported prostheses. A proper design is vital in the success of such a prosthesis like any other. This study, in the shortage of scientific evidence, has tried to assess the stress distribution of occlusal forces inside the implant-prosthesis system of a 3-unit bridge made of monolithic zirconia. Methods. A 3-unit monolithic zirconia bridge supported by two implant fixtures placed on the teeth #13 and #15 was digitalized. It was converted to a mesh of 59000 nodes and 34000 elements. Five types of occlusal forces (one as vertical centric, two at 15º and 30º simulating canine pattern of lateral movement, and two at 15º and 30º simulating group function pattern) were applied. The stress distribution among all the components of the implant-bridge system was assessed using Ansys Workbench 14 software and finite element analysis. Results. The maximum stress was between 286 and 546 MPa, which were found in either the fixture‒abutment screw area or in the upper part of the pontic connector between the canine and first premolar. The maximum pressure increased with an increase in the angle of occlusal force. Significantly higher stress was recorded in the group function occlusal pattern. Conclusion. Monolithic zirconia can be promising in designing bridges in the canine‒premolar area. However, proper design is necessary with more attention to the connectors and types of occlusal forces.

A survey was conducted through a printed and online standard questionnaire with 18 open as well as multiple choice questions delivered to dental practitioners. All data were collected and coded, the statistical analysis was done using SPSS statistical software package. Descriptive statistics were used for data analysis. Result: The study showed that 167 (66.8%) were males while 83 (33.2%) were females. 80 (32%) of dentists were practicing crown and bridge for 1‑3 years, 88 (35.2%) of dentists were practicing crown and bridge for 4‑10 years, 38 (15.2%) of dentist were practicing for 11‑15 years while 44 (17.6%) of them were practicing for more than 16 years. Most of respondents 175 (70%) worked in private clinics. 90(36%) of participants fabricated study models before commencing fixed prosthodontic treatment. 190(76%) of participants always used radiographs for abutment tooth evaluation. Vitality test for restored abutments were always done by 115 (46%) respondents. Majority of respondents 200 (80%) were using high-speed hand pieces and diamond bur during preparation 130 (52%) While preparing of teeth for dental prosthesis. additional cured silicon was mostly used by most of the practitioners 110 (44%) for making final impression with a Putty and wash techniques 183 (73.2%).165 (66%) participants used wax for bite registration, 100 (40%) of respondents always used retraction cord and 08(43.2%) practitioners never give provisional crown and bridges. Both written prescriptions and verbal communications were used during communication between dentist and lab by 175 (70%) respondents. Conclusion: The dental practitioners of Eastern part of Nepal displayed acceptable level of knowledge and awareness regarding fixed prosthodontics practice. However, to further enhance efficiency and performance, an effort should be made to update the knowledge by conducting CDE on recent advances in dentistry and dental practices.

Abstract (sommario):

Manufacture of 3D objects is of most extreme significance in different medical fields counting dentistry. Its appearance started when Charles Hull printed, for the first time, in 1984, a 3D object using the first 3D printer. 3D printing is well gotten by dental experts because of its capability to create complex parts with ease, accuracy, ease of fabricating and decreased chair time permitting the dental practitioner to supply more successful treatment. 3D printing is an additive manufacturing process in which a 3D object is created by the establishment of successive material layers. There are various 3D printing techniques, mainly stereolithography, selective laser sintering, fused deposition modeling in dentistry, which is mainly used in teaching and or managing cases involving implants, different surgeries, periodontal treatment, crowns and bridges, endodontic and orthodontic appliances. This article is focused around the various technologies of additive manufacturing, its developing applications, advantages and limitations in the field of dentistry.

Abstract (sommario):

Purpose: To compare the dimensions accuracy and surface roughness of polymeric dental bridges produced by different 3D printers. Design/methodology/approach: Four-part dental bridges were manufactured by three printing systems working on the basis of digital light projection (DLP) stereolithography (SLA), laser-assisted SLA and fused deposition modeling (FDM). The materials used from SLA printers are liquid methacrylate photopolymer resins, while FDM printer use thin wire plastic polylactic acid. The accuracy of the external dimensions of dental bridges was evaluated and the surface roughness was measured. Findings: It was found that compared to the base model, the dimensions of the SLA printed bridges are bigger with 1.25%-6.21%, while the corresponding dimensions of the samples, made by FDM are smaller by 1.07%-4.71%, regardless the position of the object towards the substrate. The samples, produced by FDM, are characterized with the highest roughness. The average roughness deviation (Ra) values for DLP SLA and lase-assisted SLA are 2.40 μm and 2.97 μm, respectively. Research limitations/implications: For production of high quality polymeric dental constructions next research should be targeted to investigation of the polymerization degree, stresses and deformations. Practical implications: Our study shows that 3D printers, based on laser-assisted and DLP SLA, can be successfully used for manufacturing of polymeric dental bridges – temporary restorations or cast patterns, while FDM system is more suitable for training models. The results will help the dentists to make right choice of the most suitable 3D printer. Originality/value: One of the largest fixed partial dentures – four-part bridges, produced by three different commercial 3D printing systems, were investigated by comparative analysis. The paper will attract readers’ interest in the field of biomedical materials and application of new technologies in dentistry.

Abstract (sommario):

AbstractResin-bonded bridges are one of the main options for replacing missing teeth for hypodontia patients. This technique offers several advantages for these patients, who are often young, have unrestored abutment teeth, and have had tooth positions optimised by orthodontic treatment. However, the replacement of missing teeth can be challenging due to tooth positions and anomalies of abutment tooth shape and size.These patients are often young adults at the time of restoration, making the minimally invasive nature and predictable long-term success of resin-bonded bridges advantageous over other treatment methods.This paper in the hypodontia themed issue discusses the importance of case selection and gives practical advice for the design and provision of resin-bonded bridges.

Abstract (sommario):

Summary. Having and maintaining a smile aesthetic is an essential component of modern popular culture. Adhesive bridges («Maryland bridge») have been developed to eliminate single included defects in the dentition in the frontal areas, without preparing the supporting teeth. In modern conditions this technology is the method of choice since single defects in the anterior part of the dentition can also be eliminated through orthodontic treatment, manufacturing of a partially removable plate prosthesis, a traditional dental bridges, the manufacturing of cantilever orthopedic structures and prosthetics based on a dental implant. Adhesive dentures are a relatively new dental technology (which is on the border of orthopedic and therapeutic dentistry) the first work in this direction was carried out in the early 80s of the twentieth century. Modern adhesive bridges are divided into two large groups – solid metal and photopolymer (composite) which prevail in practice. The optimal form of the release of the reinforcing element which combines a slight preparation of abutment teeth to a safe depth, high physical and mechanical properties, simple achievement of the anatomical shape of the teeth in the bridge structures of the anterior and posterior teeth is fiberglass in the form of ribbons 2 mm wide, up to 0.5 mm (this is the most effective width and thickness for clinical practice) and braided type. Using adhesive bridges, it is possible to optimally restore the aesthetics of the anterior part of the dentition in one visit without preliminary preparation of adjacent teeth. An example of the manufacture of a photocomposite adhesive prosthesis reinforced with glass fiber for the restoration of a single included defect in the dentition in the frontal area using domestically produced materials is given. Key words: teeth, defect, composite, adhesion, fiberglass.

Abstract (sommario):

ABSTRACT Congenitally missing maxillary lateral incisors pose a difficult esthetic and treatment planning problem for clinicians. Age, location, space limitations, alveolar ridge deficiencies, uneven gingival margins, occlusion and periodontal factors often necessitate an interdisciplinary approach. Over the last several decades, dentistry has focused various treatment modalities for replacement of missing teeth. Treatment plans for patients with missing maxillary lateral incisors have traditionally included either space closure or space reopening. To remove healthy tooth structure of adjacent teeth to replace a tooth, for some patients and dentists, is a very aggressive treatment option which eliminates the option of three unit bridges. Removable partial dentures are also not preferred for its bulkiness and reduced esthetics. Presently, the single implant supported crown is a predictable method of tooth replacement in adolescents. The aim of this case report is to provide a conservative method for the management of bilateral missing lateral incisor.

Abstract (sommario):

Introduction: Taking an impression of the oral cavity, which accurately recreates the prosthetic field, the surrounding hard dental and soft tissues, is one of the main and most important stages in the process of making any fixed prosthetic restoration. In modern prosthetic dentistry, impressions taken with the help of polyether and vinyl polysiloxane impression materials are common. Digital impressions eliminate some of the steps of conventional impression techniques and save clinical time. Aim: The aim of this article is to compare the clinical time in digital and conventional impression techniques from a whole dental arch using a controlled clinical trial. Material and methods: The present study includes 36 patients from Varna who need prosthetic treatment with fixed 3-unit bridge construction. For all participants, the conventional impression technique was performed first and one week later - the digital one. All clinical manipulations related to the implementation of the two impression techniques were performed according to the instructions of the manufacturing companies by the same specialist dentist. Results: In all participants, the time required to perform the digital impression technique is significantly less than that of the conventional impression technique. Conclusion: The digital impression technique has proven to be more efficient in terms of clinical time required for its implementation than the conventional impression technique.

Abstract (sommario):

Abstract This essay focuses on a thirteen-inch-high reclining chair with a carved walnut frame, brass base, and emerald green velvet upholstery in the Winterthur Museum collection [1 and 2]. Created by Ira Salmon of Boston circa 1866, the chair is a patent model and part of Salmon’s efforts to win a professional reputation as a dentist early in his career. This essay documents the transformation of dentistry in America from an itinerant practice in the early republic to a professionalized career in the mid-nineteenth century. It offers evidence of how the material world of dentists changed when tools of the profession became standardized and mass produced. Developing technologies facilitated reclining chairs suited for newfangled operative techniques. The essay also focuses on a period that anticipates the development of germ theory in the early twentieth century and the sterilization of the dentist’s office. In this mid-nineteenth century moment, the aesthetics of dentist offices, and their chairs’ designs, bridge a divide between the traditional values associated with dentists and those ascribed to dentists today. The patent model demonstrates Salmon’s desire to appeal to his clients’ interest by capturing the dramatic potential of a dentist’s visit while satisfying their desire for comfort and expectation of skilful technique.

Abstract (sommario):

Over the last 10 years, the use of zirconium dioxide ceramics as a framework material for the manufacture of microprostheses, single crowns and small bridges has increased. Their use in dental practice became possible with the help of CAD/CAM technologies. Clinical studies of ceramic restorations based on zirconium dioxide showed promising clinical results and high survival rates. However, chipping and fragility of ceramic masses layered on frameworks made of zirconium dioxide remains an actual and urgent problem of modern orthopedic dentistry. In modern global dental practice, layer-by-layer veneering on refractory models, CAD/CAM technology, and hot pressing techniques are used to achieve such results. In modern dentistry, the IRS e.max Press technologies occupy a rather significant place due to the simplicity and manufacturability of the process, but their use is restrained by the fear of orthopedists-dentists related to the fragility of metal-free structures and the complexity of clinical stages. Therefore, most often in case of destruction of the crown part of the tooth, metal hip inserts are used, the manufacturing technology of which continues to be improved. That is why in modern orthopedic dentistry, the problem of improving the quality of restoration of the frontal group of teeth by improving and approving the technology of pressed ceramics is urgent.
