Orthodontic technology has advanced significantly, allowing an orthodontist to precisely design the course of therapy. The software enables the analysis of dental mobility and the provision of digital treatment choices. Cephalometric analysis, digital imaging, intraoral and extraoral image capture, morphing capability to show patients what their teeth could look like after treatment, case presentation capability, treatment planning capability, and oral maxillofacial surgery applications are typical features of orthodontic practice software and orthodontic digital treatment planning systems. You can give patients graphics through these technologies that will assist them in understanding the benefits of proceeding with orthodontic or surgical-orthodontic therapy. Since patients can now comprehend and see the treatment plan, communication between clinicians and patients has also become easier due to digitization. Thanks to digital orthodontics, getting a healthier and straighter smile is much easier. Because of this, the majority of this assessment is based on software that is currently accessible for orthodontic applications.

Orthodontics is one branch of dentistry which deals with dynamic manipulation and function of the stomatognathic system. Likewise, it has to witness the dynamic changes in its diagnosis method and treatment planning. The field of orthodontics has witnessed many revolutionary techniques and evolved enormously in terms of benefiting the patient. CAD/CAM is one promising methodology that has shown a significant impact in modern dentistry and surpassed some of the challenges an orthodontist has been facing all these years. It has changed the view through which we see the patient’s condition. The application of 3D technology allows the practitioner and patient to utilize virtual treatment planning software to better identify case objectives and visualize treatment outcomes. CAD/CAM has many applications in orthodontics, which include aids for diagnosis and treatment planning, clear aligner treatment, customized lingual appliances, customized brackets with patient-specific torque, machine-milled indirect bonding jigs, robotically bent archwires, indirect bonding systems, customization of orthodontic appliances like distalization appliance etc., Acceleration of orthodontic treatment (OT) has received growing attention in recent years, especially in adult patients.Digital workflow is the current trend in orthodontic practice and has speckled every aspect of orthodontics in terms of documentation, study casts, analysis of dental malocclusion, smile designing, treatment planning and fabrication of orthodontic appliances. The current article aimed to establish a narrative description of the digital workflow and applications of the CAD/CAM process in Orthodontics.

Nanotechnology has gained importance in recent years due to its ability to enhance material properties, including antimicrobial characteristics. Nanotechnology is applicable in various aspects of orthodontics. This scientific work focuses on the concept of nanotechnology and its applications in the field of orthodontics, including, among others, enhancement of antimicrobial characteristics of orthodontic resins, leading to reduction of enamel demineralization or control of friction force during orthodontic movement. The latter one enables effective orthodontic treatment while using less force. Emphasis is put on antimicrobial and mechanical characteristics of nanomaterials during orthodontic treatment. The manuscript sums up the current knowledge about nanomaterials’ influence on orthodontic appliances.

With the development of digital information technology and big data technology, the medical industry has also undergone tremendous changes. Traditional medical treatment mainly relies on the technical experience of the attending doctor for treatment, and there is no sophisticated instrument or scientific analysis system to assist in treatment. With the improvement of people’s living standards, people’s attention to teeth has increased significantly. Traditional orthodontics is based on the subjective judgment of orthodontists and manual treatment. Due to the differences in the experience of orthodontists, the traditional orthodontic effect is often very poor. Using digital information and big data technology to carry out quantitative diagnosis and treatment analysis of teeth, 3D modeling, and simulation of prosthesis, personalized treatment of the prosthesis model, and finally applied to orthodontics, digital-based orthodontics make the orthodontic diagnosis and treatment process evidence-based, safer, and more effective. This article compares orthodontics and traditional oral orthodontics based on the mathematical model, to analyze the comfort of orthodontics, the aesthetics of orthodontics, the matching degree of aligners, and the stability of the environment in the periodontal ligament. It is concluded that the average orthodontic comfort based on the mathematical model is 85.6%, and the average aesthetic degree is 64.0%, which are more than 20% better than traditional orthodontics. It is also superior to traditional orthodontics in terms of the degree of matching of the appliance and the stability of the environment in the periodontal ligament. Therefore, the combination of mathematical models and orthodontics can lead to better orthodontic results.

Nanotechnology is the science of manipulating matter, measured in the billionths of a nanometer, roughly the size of two or three atoms. It is widely used in our day-today life including its use in medicine and is considered as a vital current technology of the 21st century based on its economic and scientific potential. Its application is being experimented in various domains in orthodontics, from surface coatings to the development of novel materials. Orthodontic materials must have specific characteristics such as biological safety, functionality, and adequate tissue response. They have to pass specific biocompatibility tests to meet regulatory standards. Any material used in oral cavity might encourage unnecessary disturbance due to its complex and varied environment. The nanomaterials have many advantages in the field of orthodontics, especially with improved mechanical and antimicrobial properties. Nanoparticles can easily penetrate tissues and can affect biological behaviours at different levels. The introduction of nanotechnology gives better opportunities to both patient and orthodontist to new physicochemical, mechanical, and antibacterial properties of nanosized materials and can be used in coating orthodontic wires, elastomeric ligatures, and brackets, producing shape memory polymers and orthodontic bonding materials. The present review article focuses on the application of nanoparticles in orthodontics. This article presents a brief overview of nanotechnology, types of nanoparticles, biological safety of different nanoparticles used in orthodontics and their applications in the field of dentistry and orthodontics.

Malocclusion is the world's third most common oral ailment. The fixed orthodontic procedure is now the most successful treatment strategy for malocclusion. Archwire bending is an important part of orthodontic therapy. However, because to the great stiffness and exceptional flexibility of orthodontic wire, it is a very difficult task. The old method of obtaining the created archwire curve is dependent on manual operation, which would bring various errors induced by human causes. Customised archwires are required in clinics for lingual orthodontics treatment. Previously, only expert orthodontists could physically bend these archwires. This is a pattern demands specialised skill training, precision, and extensive chairside time, but cannot guarantee the accuracy of appliances. So, what are the most recent developments?

Summary. Today, the need for orthodontic treatment of anomalies of tooth position and occlusion is constantly growing. In the practice of orthodontics use a variety of orthodontic appliances. The most widely used non-removable appliances that allow treatment of adult patients. However, dentists often intensify orthodontic appliances to speed up the end of treatment result. Unfortunately, this has a very adverse effect on periodontal tissues. This article analyzes the data of the dental literature on the impact of orthodontic treatment on the hard tissues of the teeth and, especially, on the periodontium. The main factors of periodontal damage during orthodontic treatment are determined. An analysis of possible areas of prevention of periodontal disease during orthodontic treatment was presented. Key words: orthodontic treatment, oral cavity, periodontium, periodontal lesions, prevention.
Objectives: Dental Monitoring® (“DM,” Dental Monitoring, Paris, France), is a cloud-based software that allows orthodontists to track patients’ treatment remotely. The purpose of this study was to investigate the accuracy of the software in making linear measurements.
Methods: Patients took intraoral photographs using the DM application, immediately followed by impressions for plaster models. Intercanine and intermolar width and arch depth measurements were made by DM and compared to measurements made on the plaster models. Data was analyzed using two one-sided t-tests for equivalence with equivalence bounds of
+/-0.5mm. Significance level was set at 0.05.
Results: Thirty sets of measurements were compared. The intercanine and intermolar measurement differences were on average 0.17mm and -0.02mm, respectively, and were deemed equivalent. The arch depth measurements had an average difference of -0.54mm and were deemed not equivalent.
Conclusion: The monitoring software seems to provide an accurate assessment of linear tooth movements.

L'analyse et le diagnostic précis à partir d'images dentaires sont un facteur essentiel de la réussite des traitements orthodontiques. De nombreux procédés de traitement d'image ont été proposés pour résoudre ce problème. Cependant, ces études fonctionnent principalement sur de petits ensembles de données de radiographies dans des conditions de laboratoire et ne sont pas vraiment applicables en tant que produits ou services complets. Dans cette thèse, nous construisons des modèles d'apprentissage profond pour diagnostiquer des problèmes dentaires tels que la gingivite et les dents chevauchées à l'aide de photos prises par de téléphones portables. Nous étudions les couches cachées de ces modèles pour trouver les forces et les limites de chaque méthode. Nous proposons un pipeline complet intégrant le prétraitement des images, l'apprentissage du modèle et le post-traitement des résultats pour créer un processus d'analyse complet prêt à être mis en production en situation réel. Afin d'améliorer la fiabilité des modèles, nous avons étudié différentes méthodes d'augmentation des données, en particulier les méthodes d'adaptation de domaine en utilisant des approche de transfert d'images, à la fois supervisée et non supervisée, et obtenons des résultats prometteurs. Les approches de transformation d'images sont également utilisés pour simplifier le choix des appareils orthodontiques par les patients en leur montrant à quoi pourraient ressembler leurs dents pendant le traitement. Nos méthodes permettent de générées des images réalistes et en haute définition. Nous proposons également un nouveau modèle de transformation d'image non supervisé qui peut manipuler les caractéristiques de l'image sans nécessiter d'annotation supplémentaire. Notre modèle surpasse les techniques de pointe sur plusieurs applications de transformation d'images et est également étendu pour les problèmes de « few-shot learning » Accurate processing and diagnosis of dental images is an essential factor determining the success of orthodontic treatment. Many image processing methods have been proposed to address this problem. Those studies mainly work on small datasets of radiographs under laboratory conditions and are not highly applicable as complete products or services. In this thesis, we train deep learning models to diagnose dental problems such as gingivitis and crowded teeth using mobile phones' images. We study feature layers of these models to find the strengths and limitations of each method. Besides training deep learning models, we also embed each of them in a pipeline, including preprocessing and post-processing steps, to create a complete product. For the lack of training data problem, we studied a variety of methods for data augmentation, especially domain adaptation methods using image-to-image translation models, both supervised and unsupervised, and obtain promising results. Image translation networks are also used to simplifying patients' choice of orthodontic appliances by showing them how their teeth could look like during treatment. Generated images have are realistic and in high resolution. Researching further into unsupervised image translation neural networks, we propose an unsupervised imageto- image translation model which can manipulate features of objects in the image without requiring additional annotation. Our model outperforms state-of-the-art techniques on multiple image translation applications and is also extended for few-shot learning problems

2013 Orthodontic archwires are made from different alloys. It is now possible to match phases of treatment with orthodontic archwires according to its mechanical properties. On this basis, the titanium molybdenum alloys (TMA) in its beta phase have an excellent combination of strength and flexibility when used as archwires to apply biomechanical forces that affect tooth movement. It has recently gained increased popularity in orthodontic treatment. There are, however, disadvantages associated with the use of orthodontic archwires, such as high surface roughness, which increases friction at the archwire-brackets interface during the sliding process. The surface roughness of dental materials is of utmost importance. Properties such as desirable tensile strengths, load deflection, hardness and low modulus of elasticity and resistance against corrosion & wear determine the area of the contact surface, thereby influencing the friction.
The main object of this study was to improve the strength and surface roughness of the beta-titanium orthodontic archwires (β-Ti III) and timolium archwires (TIM), taking into account of retention of the archwires strength. The following tasks were performed. Layers of Zr were deposited on the β-Ti archwires and compared with the archwire strength before and after Zr deposition. The structure of selected archwires and its composition and surface roughness was investigated before and after Zr deposition, using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The force of selected archwires before and after deposition with layers of Zr by Hounsfield deflection testing was studied.
Two commercially available orthodontic archwires were used in this study, namely, β-Ti III and TIM orthodontic archwires. The archwires were cut into 25 mm long specimens. In this study, the electron beam-physical vapour deposition (EB-PVD) technique was applied to deposit pure Zr (thicknesses of 5, 10, 25 and 50 nm) on selected archwires and the effects thereof were investigated using AFM, SEM and the Hounsfield deflection test. Results of SEM and AFM analysis and deflection tests showed significant differences between Zr-coated archwires compared with uncoated archwires. Zr-coated archwires (5, 10, 25 and 50 nm depositions) had reduced surface roughness compared with uncoated archwires. A high load deflection rate was exhibited by the coated β-Ti III archwires and a low load deflection rate was exhibited by the coated TIM archwires. There was a difference in load deflection rate between the coated and uncoated archwires. Deposition of 5, 10, 25 and 50 nm Zr on both types of β-Ti orthodontic archwires is recommended for even sliding mechanics due to resulting reduced surface roughness with a good load deflection rate compared with uncoated β-Ti orthodontic archwires.

Les progrès des nombreux champs qui composent la médecine possèdent de nombreuses origines, l'une d'entre elles étant l'évolution des matériaux utilisés. En particulier, l'essor des matériaux dit intelligents permet d'envisager de nouvelles solutions techniques, ou bien d'améliorer significativement les dispositifs existants ou leur tenue en service. Les alliages à mémoire de forme font partie de cette famille des matériaux intelligents, en raison de leur comportement dépendant de la température. Leur comportement mécanique est par conséquent plus complexe par rapport à des matériaux plus connus comme les aciers. Cela permet par exemple d'atteindre un niveau de déformation réversible de l'ordre de plusieurs pourcents. L'une des premières applications de ces matériaux concerne le domaine de l'orthodontie, avec le développement de fil orthodontique en alliage à mémoire de forme NiTi. Son intérêt est de profiter de l'application d'une force quasi-constante au cours du traitement. Une problématique à laquelle sont confrontés les chirurgiens-dentistes est celle due à la présence d'hydrogène qui conduit à une rupture prématurée et d’une dégradation des propriétés mécaniques de fils en NiTi lors des traitements orthodontiques. Le caractère fragile de la rupture est un indice sur l'origine multi-physique de ce problème. Ce sujet de thèse propose d'analyser ces effets de l'hydrogène sur le comportement pour ensuite prendre en compte les phénomènes prépondérants dans un modèle élément fini. Pour cela, on s'appuiera sur des résultats expérimentaux pour développer un modèle de comportement couplé chimio-thermo-mécanique adapté. Deux éléments finis (2D et 3D) à degrés de liberté chimio-thermo-mécanique seront formulés en considérant la loi de comportement développée. Ils seront ensuite implémentés dans Abaqus via une UEL pour étudier les effets de la diffusion de l'hydrogène et son absorption sur le comportement ainsi que ses répercussions, par exemple sur le piégeage de martensite. Les prédictions par éléments finis des effets de l'hydrogène sur les performances des arches dentaires en AMF NiTi seront confrontées aux observations expérimentales Advances in the many fields that form medicine have many origins, one of them being the evolution of the materials used. In particular, the rise of the intelligent materials enables to consider new technical solutions, or to significantly improve existing devices. Shape memory alloys belong to this family of intelligent materials, due to their temperature dependent behavior. Their mechanical behavior is therefore more complex compared to more well-known materials such as steels. This allows, for example, to achieve a level of reversible deformation of the order of several percent. One of the first applications of these materials concerns the field of orthodontics, with the development of orthodontic wire in NiTi shape memory alloy. Its interest is to take advantage of the application of an almost constant force during the treatment. One problem with which dentists are confronted is due to the presence of hydrogen which leads to premature rupture and degradation of NiTi wires mechanical properties during orthodontic treatments. The brittle nature of the rupture is an indication of the multi-physical origin of this issue. This PhD proposal will focus on the analysis of these hydrogen effects on the thermomechanical behavior of Shape Memory Alloys (SMAs) in order to develop a finite element model. For that end, experimental characterizations will be carried out and analysis of obtained results will allow to formulate an adapted coupled chemo-thermo-mechanical constitutive model. This behavior model will be integrated in two special finite elements (2D and 3D) with coupled degrees of freedom (thermal, mechanical and chemical degrees of freedom). These elements will be implemented in the Abaqus code via the subroutine UEL. The obtained numerical tool will allow to analyze the effect of hydrogen diffusion on the performance of SMA-based orthodontic arches. These finite element predictions will be confronted with experimental observations

Thesis, King's College London (University of London), 2017. https://kclpure.kcl.ac.uk/portal/en/theses/the-angiogenic-response-of-human-dental-pulp-to-orthodontic-force-application(518decf5-ed49-4c36-b2a0-99a56f089802).html.
In order to characterise the angiogenic response of human dental pulps to orthodontic force application, transcriptomic and proteomic changes were investigated relative to three early time-points of routine clinical treatment in contralateral pairs of treated and control teeth. It was hypothesised that varied intensities of hypoxic exposure (intermittent, repeated intermittent and chronic) would result in distinct angiogenic responses within untreated pulp tissues. It was further hypothesised that angiogenic responses of pulps exposed to early time-points of orthodontic treatment would correlate with those of tissues exposed to varied hypoxic intensities; and changes would be associated with known stages of clinical treatment, namely: initial, lag, acceleration and linear phases of orthodontic tooth movement. Prior to performing all experimentation, methodologies for handling of rare clinical samples were established. Protocols for sample storage, homogenisation, RNAtotal isolation, quantification, purification and amplification were optimised; a normalising factor created from the mean expression of reference genes RPL13A and UBC was found to be most appropriate for RT-qPCR analysis of human dental pulps under these experimental conditions. Orthodontic force application resulted in a potential angiogenic or putative inflammatory response at all treatment time-points; and altered gene expression associated with hypoxia is evident in pulps following 2 weeks of force application. The response to each defined hypoxic intensity was unique; and the associated angiogenic response correlated with the duration of hypoxic exposure. Reoxygenation following hypoxia was linked to the putative inflammatory response of pulps during orthodontic treatment. Results showed that the experimental potential of a single clinical sample can be amplified significantly, dependent upon the selection of specific experimental protocols; thus eliminating the need for pooling samples or using cell lines which are far removed from true physiological conditions. Both angiogenesis and hypoxia appear to have a significant role in response of human dental pulps to routine orthodontic treatment.

Maumela, Patricia Mutsinda. "Application of the dental aesthetic index in the prioritization of orthodontic service needs." Thesis, University of Limpopo (Medunsa Campus), 2010. http://hdl.handle.net/10386/444.
Thesis (M.Med. (Orthodontics))--University of Limpopo, 2010 Introduction: Orthodontic services in South Africa are mainly offered by the private sector and to a lesser extent by the four government funded training institutions which are plagued by limited resources. The majority of patients cannot afford private fees and seek treatment at these training institutions. The growing number of patients on waiting lists is a problem. Prioritization of orthodontic services would assist to ensure that these services are preferentially provided to those patients most likely to derive the greatest benefit.
The Dental Aesthetic Index (DAI) is used to estimate orthodontic treatment need and can also be used as a screening tool to determine treatment priority (Cons, Jenny & Kohout, 1986). The DAI focuses on aesthetics and therefore omits other malocclusion traits thereby limiting its comprehensiveness as an assessment tool. To date no published study has been found that identified other malocclusion traits not included in the DAI and examined the influence that these malocclusion traits have in the prioritization of orthodontic service needs whilst using the DAI.
Thus the aim of this research was to assess the application of the DAI to prioritize orthodontic services needs within a government funded institution. The objectives were: 1) To identify other malocclusion traits not included in the DAI. 2) To evaluate how much influence other malocclusion traits not included in DAI have in the prioritization of orthodontic service needs. 3) To compare the mean DAI scores according to age and gender.
Materials and methods: One hundred and twenty (120) pre-treatment study models of patients in the permanent dentition stage were collected from the records archive of the Department of Orthodontics, University of Limpopo (Medunsa campus) using a systematic sampling method. The study models were assessed using the DAI by two calibrated examiners.
Other malocclusion traits were identified and recorded according to the basic method for recording occlusal traits (Bezroukov et al., 1979). Specific codes were assigned to each identified malocclusion trait from code 01 to 09. The traits were recorded once, by marking the respective code/malocclusion trait with an x when present on each study model.
Descriptive statistics, Pearson correlation coefficient, Chi-square values and t-tests were employed to analyze the data and p values of less than or equal to 0.05 (p < 0.05) were considered statistical significant.
Results: The sample consisted of 58 females and 62 males, aged 10-45 years with a mean age of 17.9 years and a SD of 6.2 years. The DAI scores showed that 19.1% had normal or minor malocclusion, 17.5% had definitive malocclusion, 21.7% had severe malocclusion and 41.7% had handicapping malocclusion. The mean DAI score was 35.2 with a SD of 10.3. A statistical significant difference was found between mean DAI score of adults and adolescence (p < 0.05), while no statistical significant difference was found between males and females (p > 0.05).
The study identified the following other malocclusion traits: crowded and rotated posterior teeth (27.5%), posterior crossbite (22.8%), retained primary teeth (13.4%), missing molars (10.7%), partially erupted teeth (9.4%), deep overbite (8.1%), transposition (3.4%), peg lateral (3.4%) and supernumerary teeth (1.3%). These malocclusion traits accounted for 21.1% of the total malocclusion traits of the sample whilst the DAI accounted for 78.9%.
About 47.6% of these other malocclusion traits were found in handicapping category of the DAI, 19.5% in the severe category, 18.1% in the definitive category and 14.8% in the normal or minor category. The distribution of subjects over the four DAI categories and the distribution of subjects with other malocclusion traits over the same DAI categories did not differ significantly (Chi-square test, p = 0.917). The intra and inter examiner reliability was tested using the Pearson correlation coefficient and found to be highly correlated (r = 0.9).
Conclusions: The study showed that the DAI is a valid and reliable index that can be applied to prioritize orthodontic service needs in a financially constrained situations without any modification as two thirds of other malocclusion traits were found in categories which the DAI had already prioritized for treatment.

In orthodontic treatment, anchorage is the most important element that affects the treatment’s success. To improve the load bearing capacity of the anchorage there are several devices developed in recent decades such as midpalatal implants and onplants but they also have limitation on directions of applied load and their support position adjustability. The purpose of this study was to investigate the efficiency of a new anchorage device by analyzing the load-bearing and stress distribution among the cortical and cancellous bones of the mandible as well as the anchorage system components using nonlinear 3D Finite Element (FE) method. The new device is composed of an adjustable stainless steel plate equipped with bracket and mounted with two titanium mini-screws into the mandible. The response of this new system was compared to an isolated mini-screw system under different loading scenarios. A maximum of 500gr force was applied in different directions on the bracket and the isolated mini-screw head to simulate the orthodontic loading. Using the new anchorage device reduced von-Mises stress in the whole structure approximately by 50% comparing to the isolated mini-screw. In the cortical bone and depending on the direction of the applied force, von-Mises stress decreased from 6 to 3MPa under vertical shear force and from 6 to 1.5MPa under horizontal and inclined shear forces. In the cancellous bone the stress decreased similarly as in the cortical bone from 0.6 to ≈0.3MPa under horizontal and inclined shear. Under vertical shear force the decrease was less significant from 0.57MPa to 0.5MPa. This new device while offering wide fields of orthodontic forces applications thanks to its bracket provides the same resistive force (500gr) as the isolated mini-screw with much lower stresses in the bone and anchorage implant as well. The next step is to investigate the efficiency of this new device in the teeth movement.
