Abstract:
BACKGROUND Clear aligners are orthodontic devices that are transparent, a plastic used to correct malaligned teeth. Here patient wears a series of customized clear, removable aligners that gradually move the teeth to the desired position. The clear aligner system is a modern adaptation of the systems described since the middle of the 20th century, therefore there were different devices and philosophies that have led to its creation and the system has evolved a lot over the decades. Clear aligner therapy has been a part of the orthodontic practice for years, but, popularity was increased since the introduction of Invisalign appliances (Align Technology) in 1998. There are almost 27 different clear aligner products currently on offer for orthodontic treatment. Nowadays, more people prefer clear aligner treatment because it is aesthetically superior to brackets and lingual orthodontics. The superiority of clear aligners lies in their aesthetics. The optical properties of the clear aligner material play a major role in aesthetics. The rising demand among adult patients for “invisible” orthodontic treatment has led to an exponential growth in the clear aligner market. Indeed, these aligners have a low aesthetic impact, as well as being able to effectively and progressively guide the teeth into their programmed positions. They are also removable and therefore do not hamper oral hygiene maintenance, in turn reducing the risk of white spots, caries, gingivitis and periodontal disease. All the materials do not possess the same chemical composition. The properties change before and after wear. In this article, we bring out the different materials used for the manufacture of clear aligners and their various properties.

Abstract:
As the demand for aesthetic treatments is increasing, more people are seeking alternatives to fixed orthodontic appliances. Clear align­ers are aesthetically pleasing and comfortable option for orthodontic treatment and have gained immense popularity over the last decade. Moreover, with increasing demand there has been a constant attempt for cost reductions by number of aligner companies and laboratories. It will be beneficial not only to orthodontist but also to patients if aligners can be fabricated in-house itself. Thus, this review will highlight the fabrication of In-house aligners in detail.

Abstract:
The clear aligner treatment in the last years has been increasing its relevance and use. The use of aligners to treat malocclusion has had a remarkable surge in the last decades, a growing interest has been reported for such methods of invisible orthodontics, especially among adult patients. Clear aligners are orthodontic devices that use elastic thermoplastic material, applying pressure to the teeth to move into the aligner’s position, being an alternative to dental braces. They are esthetic, efficient, and comfortable compared to a traditional fixed appliance for mild-to-moderate malocclusion. A clinician should know strengths and weaknesses of aligners for a correct use, being guided by clinical indications. The present paper will highlight the increasing popularity of clear aligner appliances, as well as the clinical scope and the limitations of aligner therapy in general.

Abstract:
Aesthetics is a major factor in Orthodontic treatment and it is a primary concern among patients seeking orthodontic treatment. To meet the growing aesthetic desire for an alternative to traditional braces, researchers have created a variety of alternatives, including ceramic or composite braces, lingual orthodontics, and transparent aligners. Clear aligner therapy is a treatment that consists of a set of clear dental appliances that are custom-made to fit the contour of a patient's teeth. Clear Aligners are an alternative to traditional braces that are used to guide teeth into appropriate alignment. Clear aligners, like braces, utilise a progressive force to regulate tooth movement, but without the need of metal wires or brackets.

Abstract:
The paradigm shift in orthodontics arrived with the introduction of Aligner System. It allows both dental practitioner and patient to develop a visual understanding of orthodontic tooth movement. The esthetic and practical advantages of the system have extended orthodontic services to a greater population. The transparency of the clear aligners enhances its esthetic appeal for those adult patients who are averse to wearing conventional labial fixed orthodontic appliances. Although guidelines about the types of malocclusions that this technique can treat exist, few clinical studies have assessed the effectiveness of the appliance.

Abstract:
Lately, in orthodontic treatments, the use of transparent aligners for the correction of malocclusions has become prominent owing to their intrinsic advantages such as esthetics, comfort, and minimal maintenance. Attempts at improving upon this technology by varying various parameters to investigate the effects on treatments have been carried out by several researchers. Here, we aimed to investigate the biomechanical and clinical effects of aligner thickness on stress distributions in the periodontal ligament and changes in the tooth’s center of rotation. Dental finite element models comprising the cortical and cancellous bones, gingiva, teeth, and nonlinear viscoelastic periodontal ligaments were constructed, validated, and used together with aligner finite element models of different aligner thicknesses to achieve the goal of this study. The finite element analyses were conducted to simulate the actual orthodontic aligner treatment process for the correction of malocclusions by generating pre-stresses in the aligner and allowing the aligner stresses to relax to induce tooth movement. The results of the analyses showed that orthodontic treatment in lingual inclination and axial rotation with a 0.75 mm-thick aligner resulted in 6% and 0.03% higher principal stresses in the periodontal ligament than the same treatment using a 0.05 mm-thick aligner, respectively. Again, for both aligner thicknesses, the tooth’s center of rotation moved lingually and towards the root direction in lingual inclination, and diagonally from the long axis of the tooth in axial rotation. Taken together, orthodontic treatment for simple malocclusions using transparent aligners of different thicknesses will produce a similar effect on the principal stresses in the periodontal ligament and similar changes in the tooth’s center of rotation, as well as sufficient tooth movement. These findings provide orthodontists and researchers clinical and biomechanical evidence about the effect of transparent aligner thickness selection and its effect on orthodontic treatment.

Abstract:
As an innovative approach to overcome the rate-limiting staging of conventional aligners, using shape memory polymers (SMPs) as aligners’ materials was investigated in this in vitro study. The ability of SMPs to shape recover and consequently move tooth, upon appropriate stimuli, was evaluated on a typodont model before clinical application. The study design was to achieve 1.9 mm correction movement of an upper central incisor by one aligner after multiple steps/activation. A custom-made aligned typodont model with a movable upper central incisor was scanned. Using an orthodontic software and a 3D printer, resin-models were generated. Seven aligners of ClearX sheets (SMPs) were fabricated by thermoforming on the resin aligned model. Each aligner was tested for repositioning of the central incisor in the typodont model. The model was scanned after each step and the corrective movement was measured through the superimposition of scans. Results showed that the total correction efficiency of the SMPs’ aligner was ≈93% (1.76 mm). The corrective movement was 0.94 ± 0.04 mm after the reforming step, 0.66 ± 0.07 mm after the first activation step, and 0.15 ± 0.10 mm after the second activation step. It was concluded that aligners made of SMPs could have a promising future-use in orthodontic aesthetic treatment.

Abstract:
Orthodontic therapy using aligners is a modern treatment option among adult patients. In order to have an optimal control of the orthodontic resuslts, there is a need for knowing the deformation values that can appear in each type of aligner, the optimal thickness values of the appliances and the needed number of aligners for each case. The deformation values for a 0.2 mm repositioned lower central incisor were measured with the use of some strain gauges applied at this level, after a manual set-up was manufactured. Different orthodontic forces were applied on each aligner in order to compare the deformation value during the dental correction. The thickness values of the aligners that were used for this study were 0.625 mm, 0.75 mm and 1 mm. The 0.625 mm aligner had the lowest deformation value dueto a high elasticity of the material.

Abstract:
Background. The composite attachment loss during orthodontic clear aligner therapy is an adverse event that commonly happens in our daily practice. However, there is a lack of related statistical analysis and studies analyzing the related risk factors. Therefore, the aim of this study is to assess the incidence of attachment loss during orthodontic clear aligner therapy and to identify rick factors that may predict such event. Materials and Methods. The demographics and clinical variables of 94 patients undergoing clear aligner therapy (27 males and 67 females; average age: 27.60 ± 0.86 years ) were recorded. Both patient-related and tooth-related attachment loss was recorded. The chi-squared test and logistic regressive analysis were applied to identify the potential risk factors. SPSS for Mac (version 23.0, IBM, USA) was used for statistical analyses. P < 0.05 was considered statistically significant. Results. Our study suggested that the risk factors for attachment loss include frequent aligner removal (≥ 5 times a day) ( losing rate = 60.0 % , P = 0.005 ), aligner wear time less than 18 hours a day ( losing rate = 50.8 % , P = 0.014 ), eating without aligners inserted ( losing rate = 47.9 % , P = 0.034 ), utilizing aligner tray seaters ( losing rate = 48.2 % , P = 0.006 ), and unilateral mastication ( losing rate = 52.1 % , P = 0.002 ). The multivariable logistic regression analysis indicates that aligner wear time less than 18 hours a day ( P = 0.020 , B = 0.925 ), using aligner tray seaters ( P = 0.007 , B = 1.168 ), and unilateral mastication ( P = 0.034 , B = − 0.458 ) were considered independent factors that can predict the composite attachment loss in orthodontic clear aligner therapy. Conclusion. Wearing aligner less than 18 hours a day, using aligner tray seaters, and unilateral mastication may contribute to increased incidence of composite attachment loss during orthodontic clear aligner therapy.

Abstract:
Purpose: To evaluate the factors that influence potential orthodontic patients choosing between an orthodontist, general dentist, and direct-to-consumer (DTC) aligners for their treatment, and to determine the demand for each provider type. Methods: An electronic survey was administered to 250 individuals among the general population of adults in the United States. Questions were designed to determine the respondent’s level of interest in pursuing orthodontic treatment with each provider type, evaluate their current level of knowledge concerning provider options, and identify factors influencing their selection. Pearson’s chi-squared test and ANOVA were used to evaluate the factors influencing patients in their selection. Results: When asked their preference in provider type, 43.8% of respondents selected orthodontist, 34.1% selected DTC aligners, and 22.1% selected general dentist. Among respondents with the highest level of interest in pursuing orthodontic treatment, 50% selected an orthodontist and 27% selected DTC aligners. For respondents with moderate levels of interest in pursuing treatment, only 21% selected an orthodontist and 48% selected DTC aligners. The biggest perceived advantage of treatment with an orthodontist was quality of treatment, and the biggest disadvantage was cost. For DTC aligners, the biggest perceived advantage was convenience, followed by cost, and the biggest disadvantage was quality of treatment. Among adults with children, 34% selected DTC aligners for themselves and only 16% selected DTC aligners when selecting for their children. Conclusion: Adults in the United States have similar levels of interest in pursuing orthodontic treatment with orthodontists and DTC aligners and, to a lesser degree, general dentists. A significant portion of those who select DTC aligners for their treatment are patients who would not have otherwise undergone treatment with an orthodontist. Patients tend to select orthodontists due to quality of treatment, whereas DTC aligners are selected due to convenience, followed by cost. Even among parents who prefer DTC aligners for their own treatment, parents tend to select an orthodontist for their child’s treatment.

The relationship between applied force and aligner thickness is poorly understood. Therefore, the aims of the present study were to: 1) Evaluate the effect of initial material thickness on force output of clear aligners; and 2) Recommend a consistent, repeatable method for measuring aligner cross-section and distribution. A total of 40 clear aligners were fabricated over stereolithographic (SLA) models with ideal dentition, using proprietary gRxh material in four different thicknesses: (10) Rx15 [0.015h], (10) Rx20 [0.020h], (10) Rx30 [0.030h], (10) Rx40 [0.040h]. For measuring initial force output when tipping a tooth, a custom-made force measurement apparatus (FMA) was used with the upper right central incisor translated facially 0.25 mm. All six components of force and torque were measured (Fx, Fy, Fz, Tx, Ty, Tz) over a 16 second period of time upon seating each aligner. After gathering FMA data, cross-section and distribution of aligner material thickness was then measured using three methods for comparison: hall effect transduction, computed tomography (CT) scanning, and cross-sectional analysis under a stereomicroscope. All measurements were taken along the mid-sagittal plane of the facial surface of the upper right central incisor. Force output and variability both generally increased with an increase in material thickness. The range of measured forces were 3.5 to 28 times higher than ideal tipping forces reported by Proffit. The results for lingual force correlated well with those of total force (ã(Fx)2 + (Fy)2 + (Fz)2). As for the thickness measurement results, the hall effect transducer (HET) data correlated well with that of the CT scan. The stereomicroscope produced values that were relatively elevated. Mean measurements taken with both HET and CT consistently got smaller when moving from occlusal to middle to gingival points. The same trend was noted with the stereomicroscope, but with less consistency. The thinner Rx15 material appeared best suited for lingual tipping of a maxillary central incisor in vitro. The hall effect transducer produced simple measurements that were extremely similar to those from the CT scan, and appears to be a suitable stand-in for the more expensive and labor intensive CT scanning process.

Abstract:
Introduction: Surgically Facilitated Orthodontic Therapy (SFOT) has been utilized for years to overcome the limitations encountered with traditional orthodontic treatment of dentoalveolar and alveoloskeletal malocclusions. The procedure, which consists of full flap corticotomies and bone grafting, has many proposed benefits including increased speed and range of tooth movement. The purpose of this study is to evaluate arch expansion in patients treated with SFOT and clear aligners. Materials and Methods: A retrospective cohort study design was used to evaluate 51 consecutive adult patients that were treatment planned for significant arch expansion with corticotomies, bone grafting, and clear aligners. 17 of the 51 patients refused the surgical procedure and served as controls. Eight transverse arch width measurements were obtained at three different time points (Initial, ClinCheck, Refinement). Five calculations were performed to determine the magnitude, predictability, and efficiency of arch expansion. Results: The difference in treatment time between the two groups was statistically significant at 5.2 months (P < .0001). On average, corticotomies reduced the length of treatment by 46% and increased the rate of expansion 2.4x. Patients that received SFOT achieved a greater magnitude (+28%) of expansion at a significantly higher rate (P< 0.002) than controls for all eight interarch measurements. The SFOT group displayed higher predictability (% goal achieved) and a smaller difference between predicted and achieved tooth movements for all measures obtained. The mean age for the entire sample was 42.81 (+12.51 years). Conclusion: Arch expansion with corticotomy-assisted clear aligner therapy is significantly more effective, efficient, and predictable than with clear aligners alone. The predictability of expansion with aligners appears to have a higher range than initially thought, even in patients that do not receive corticotomies.

For each model, three retainers were made using the three methods (a total of 27 retainers). To determine the trueness, the distances between the intaglio surface of the retainers and the occlusal surface of the reference models were measured using an engineering software. A small difference was indicative of a good fit. Results: Average differences of the traditional vacuum formed retainers ranged from 0.10 to 0.20mm. The commercially-available and 3D printed retainers had a range of 0.10 to 0.30mm and 0.10 to 0.40mm, respectively. Conclusions: The traditional vacuum formed retainers showed the least amount of deviation from the original reference models while the 3D printed retainers showed the greatest deviation.

Abstract:
Introduction: Orthodontic and orthopedic expansion is necessary to create space to resolve crowding due to arch deficiency or tooth size discrepancy. The Invisalign First clear aligner appliance as a modality for early interceptive orthodontic treatment has become incorporated into orthodontic practices in very recent years. The present study aims to investigate the magnitude of expansion of the Invisalign First clear aligner appliance compared to a Schwartz removable expander in patients with mixed dentition. Additionally, the study aims to compare the efficacy and predictability of Invisalign First clear aligners in this population. Materials & Methods: In this retrospective study, a sample was collected from a single orthodontist practitioner. The sample consisted of 34 patients, 16 patients treated with Invisalign First clear aligners only (Group1) and 19 patients treated with a Schwartz removable appliance and Invisalign First clear aligners (Group 2). Intraoral scans of four timepoints, initial (T1), post-expansion for Group 2 only (T1Exp), first refinement (T2), and final (T3), and planned Clincheck goal (P) model from Clincheck software were imported to Align Technology’s digital measure program (Quantify©). Arch widths and molar inclinations were measured at each timepoint and the changes between timepoints were calculated. Predictability of arch expansion was calculated as T13 (change between initial and final) divided by the Planned dimension multiplied by one hundred. A two sample t-test was used to assess differences in the changes in arch widths and predictability of expansion between two groups. Results: There were statistically significant differences found in the magnitude of expansion and predictability of arch expansion between two groups. Group 2 showed a greater amount of expansion and predictability. Group 1 showed about 50-60% of the planned expansion at the end of treatment. In regards to magnitude of expansion when comparing the two groups, the efficacy predictability of transverse dimensional changes were significantly greater in the Group 2 compared to Group 1, 83% vs 56% (p = 0.001), respectively. The changes in inclination were similar in both groups, with no statistically significant differences.Conclusions: There is a significantly greater amount of expansion and greater predictability with the Schwartz removable appliance compared to the Invisalign First clear aligner appliance in the mixed dentition. The predictability of Invisalign First was 56% and indicates a significant overcorrection of arch expansion is required at the virtual treatment planning stage in Clincheck in order to obtain the arch expansion that was planned

Introdução: O avanço na Ortodontia que ocorreu nas últimas décadas foi impulsionado pela demanda estética. O aumento do interesse dos adultos na correção dentária impõe o fator estético como ponto determinante na decisão do tipo de aparelho ortodôntico a utilizar. Assim sendo, os alinhadores surgem como uma alternativa aos dispositivos multibrackets com arcos, uma alternativa não só confortável, mas também impercetível. Por sua vez, a responsabilidade de se realizar atualizações frequentes e conhecer as aplicações e principalmente limitações da nova técnica, é unicamente do Ortodontista. Objetivos: Esta revisão de literatura tem como objetivo avaliar as vantagens, desvantagens e eficácia clínica da Ortodontia Plástica em comparação com os sistemas multibrackets. Metodologia: Para a busca eletrônica de artigos usamos as seguintes bases de dados: “Cochrane”, “ScienceDirect”, “B-on”, “Google Acadêmico” e finalmente o “PubMed”. Restringimos a pesquisa a artigos na língua portuguesa, inglesa e espanhola publicados desde 2013 incluindo todos os tipos de estudo com preferência pelas revisões sistemáticas e meta-análises, bem como artigos chave listados nas referências dos artigos selecionados. Recorremos ainda ao arquivo bibliográfico do IUEM. Conclusão: Concluímos neste trabalho que as vantagens do uso dos alinhadores plásticos como aparelho ortodôntico apresentam a estética como principal ponto de decisão, seguido do conforto do paciente e por último da higiene oral. Por outro lado, a desvantagem dos sistemas plásticos está atualmente relacionada com a limitação de tipos de movimentos ortodônticos, sendo estes os movimentos de extrusão, rotação e torque os mais difíceis de serem alcançados. Acreditamos que avanços na tecnologia ocorrem continuamente e podem vir a mudar definitivamente as limitações ortodônticas dos alinhadores plásticos.

Objective: To assess in orthodontic treatment the distalization of uppers molars with invisalign Materials and methods: A literature review was carried out through articles and journals retrieved from the “PubMed" data base using the following keywords "orthodontic treatment", "tooth movement technique", "aligner appliances", "invisalign", "removable orthodontic appliance” “clear aligners”. Several articles were pre-selected, of which 24 were used to compose write this document. Discussion: Clear aligner as an orthodontics treatment during the distalization purposes has been a controversial topic due to its complexity and lees studies. In This paper provides a deeper knowledge of the distalization in upper molars under invisalign treatment enable and helping professionals to make the right decision when planning orthodontic treatment. Conclusion: The Upper Molars Distalization with clear aligner could be effective, being able to reach up to 3mm of movement; however, is very important for the clinician to develop a thorough knowledge of the current Align Protocol and to acquire sufficient Invisalign experience before attempting the complex movements required for successful completion of these types of cases.

Abstract:
O sistema de alinhadores do sistema Invisalign® foi introduzido como uma alternativa estética ao uso de brackets no tratamento ortodôntico. Os alinhadores são aparelhos removíveis transparentes feitos à medida e capazes de induzir movimento dentario. Face a uma maior procura por parte dos pacientes, este sistema tem evoluído significativamente com o objetivo de atingir resultados semelhantes aos obtidos com os tratamentos convencionais com brackets. Levando em conta os fatores que podem influenciar o movimento dentário ortodôntico, através de uma revisão bibliográfica, a autora deste trabalho teve como objetivo a avaliação da eficácia e eficiência do sistema Invisalign®.
Clear aligners of the Invisalign® system were introduced as an aesthetic alternative to the use of brackets in orthodontic treatment. The aligners are custom-made removable transparent appliances capable of inducing tooth movement. Faced with increasing patient demand, this system has evolved significantly in order to achieve results similar to those obtained with conventional brackets treatments. Taking into account factors that may influence orthodontic tooth movement, through a bibliographic review, the author of this work had the objective of evaluating the effectiveness and efficiency of the Invisalign® system.

Abstract:
Os sistemas de alinhadores surgiram devido ao aumento da exigência estética do tratamento ortodôntico pelos pacientes. Graças ao desenvolvimento destes sistemas e ao aumento da procura verifica-se uma evolução significativa, cujo objetivo é atingir resultados semelhantes aos obtidos com os aparelhos ortodônticos fixos convencionais, no entanto, existem outros fatores que diferem entre estes dois sistemas. Esta revisão bibliográfica tem como principal objetivo realizar uma comparação entre o aparelho ortodôntico fixo convencional e o sistema Invisalign® em relação a alguns fatores, nomeadamente, à saúde periodontal, à dor, às reabsorções radiculares e à eficácia dos tratamentos. Para além do sistema Invisalign® ter como vantagem a estética, é possível concluir que com este sistema os pacientes apresentam maior conforto, menos dor e melhor saúde periodontal, proporcionando maior qualidade de vida, contudo, não estão indicados em todos os pacientes, uma vez que, são mais eficazes no tratamento de maloclusões leves a moderadas.
The aligners system emerged due to the increase in the aesthetic demand of orthodontic treatment by patients. With the development of these systems and the increase in demand, a summarized evolution has been achieved, the objective being to achieve results like those obtained with conventional fixed orthodontic appliances, however there are other factors that differ between these two systems. The main objective of this literature review is to make a comparison between the conventional fixed orthodontic appliance and the Invisalign® system in relation to some factors, namely periodontal health, pain, root resorption and the effectiveness of treatments. In addition to the aesthetic advantage of the Invisalign® system, it is possible to conclude that with this system patients have greater comfort, less pain and better periodontal health, providing a better quality of life, however, they are not indicated for all patients, since they are more effective in the treatment of mild to moderate malocclusions.

Abstract:
Orthodontics is ‘the specialty of dentistry concerned with growth of the face, the development of dentition, and the prevention and correction of occlusal anomalies. A malocclusion can be defined as ‘a deviation from the ideal that may be aesthetically or functionally unsatisfactory, with a wide range of occlusal traits’. Orthodontics is a constantly evolving specialty, with ever changing principles and techniques continuing to be developed. There has been huge progress in orthodontics in recent times, with changes in the types of brackets, archwire materials, and appliance systems (such as tem­porary anchorage devices and aligner technology). The key principles of orthodontics date back to 1899 when Edward Angle described ‘the key to a normal occlusion as the anteropos­terior relationship between the upper and lower first molars’. In 1972, Lawrence Andrews described ‘six keys to an ideal static occlusion’. This was the basis of early orthodontic treatment planning. Knowledge of craniofacial development and growth is required as a foundation for understanding the aetiology of a patient’s malocclusion, to reach a diagnosis, and to plan orthodontic treatment. A basic under­standing of the types of orthodontic appliances is beneficial (mainly fixed appliances, functional appliances, some use of removable appliances, and retainers). In addition to the management of a malocclusion, orthodontic treat­ment is often required in conjunction with other specialties, including oral and maxillofacial surgery, paediatric and restorative dentistry Key topics discussed in this chapter include: ● Fixed appliances ● Functional appliances ● Removable appliances ● Retention ● Index of treatment need ● Orthodontic assessment and diagnosis ● Cephalometric analysis ● Malocclusion ● Ectopic canines ● Dental anomalies.

Abstract:
Clear aligners, as a transparent and removable appliance, offer an alternative to conventional fixed appliance to patients with high demands for esthetics and comfort. Only a few investigations have focused on the efficacy of clear aligner therapy in controlling orthodontic tooth movement. Furthermore, the stability after treatment has not been thoroughly investigated. The purpose of this chapter was to update the knowledge of the available evidence about effectiveness and stability of clear aligners in non-growing subjects. Searches was made in different databases from January 2015 to January 2021. Relevant articles that met the inclusion criteria were selected. The level of evidence of the studies was moderate. The vertical movements of tooth were difficult to accomplish. Mesiodistal tipping showed the most predictability (82.5%) followed by vestibulolingual tipping. Molar distalization was also recorded as the highest accuracy. Derotation was difficult to accomplish with aligners especially of rounded teeth. The effectiveness of aligners in achieving the simulated transverse goals was 45%. The stability of clear aligner therapy was assessed by only two studies. Refinements are likely needed in almost all cases and to ensure treatment stability a retention period using a specific protocol is necessary.

Abstract:
This chapter reviews T-Scan use in orthodontics from diagnosis to case finishing, and then in retention, while defining normal T-Scan recording parameters for orthodontically-treated subjects versus untreated subjects. T-Scan use in the case-finishing process is also described, which compensates for changes in the occlusion that occur during “post-orthodontic settling,” as teeth move freely within the periodontium to find an equilibrium position when the orthodontic appliances have been removed. T-Scan implementation is necessary because, often, despite there being a post treatment, visually “perfect” angle's Class I relationship established with the orthodontic treatment, ideal occlusal contacts do not result solely from tooth movement. Creating simultaneous and equal force occlusal contacts following fixed appliance removal can be accomplished using T-Scan data to optimize the end-result occlusal contact pattern. The T-Scan software's force distribution and timing indicators (the two- and three-dimensional force views, force percentage per tooth and arch half, the center of force trajectory and icon, the occlusion time [OT], and the disclusion time [DT]), all aid the Orthodontist in obtaining an ideal occlusal force distribution during case-finishing. Fortunately, most orthodontic cases remain asymptomatic during and after tooth movement. However, an occlusal force imbalance or patient discomfort may occur along with the malocclusion that needs orthodontic treatment. Symptomatic cases require special documentation at the baseline, and careful monitoring throughout the entire orthodontic process. The clinical use of T-Scan in these “fragile” cases of patient muscle in-coordination, mandibular deviation, atypical pain, and/or TMJ idiopathic arthritis, are illustrated by several case reports. The presented clinical examples highlight combining T-Scan data recorded during case diagnosis, tooth movement, and in case finishing, with patients that underwent lingual orthodontics and orthognathic surgery, orthodontic treatment using clear aligners, or conventional fixed treatment with a camouflage treatment plan, which require special occlusal finishing (when premolars are extracted in only one arch).

Abstract:
Advanced digital technology is rapidly changing the world, as well as transforming the dental profession. The adoption of digital technologies in dental offices allied with efficient processes and accurate high-strength materials are replacing conventional aligners workflows to improve overall patients’ experiences and outcomes. Various digital devices such as 3D printers, intraoral and face scanners, cone-beam computed tomography (CBCT), software for computer 3D ortho setup, and 3D printing provide new potential alternatives to replace the traditional outsourced workflow for aligners. With this new technology, the entire process for bringing clear aligner production in-office can significantly reduce laboratory bills and increase patient case acceptance to provide high-quality and customized aligner therapy.

Abstract:
Most adult patient cases are multidisciplinary cases, so it’s planning can become difficult when we need to connect many dentistry fields to achieve ideal results. The interdisciplinary reverse planning is a well-known topic for dental rehabilitation professionals, so this chapter will address the role of orthodontics in reverse digital planning, improving longevity, reducing biological impacts and helping to communicate with patients, other doctors and dental technicians. 3D CAD technology allows us to plan these complex cases before the patient starts treatment, this tool will be essential to orchestrate the exact moment to start orthodontic, prosthetic and/or surgical interventions, so the workflow becomes ordenate and the outcome will be aligned with aesthetics and functional aspects and in harmony with facial references.

Abstract:
In the last decades, research in the orthodontic field has focused on the development of more comfortable and aesthetic appliances such as thermoformed aligners. Aligners have been used in orthodontics since the mid 20-century. Nonetheless, there is still not enough knowledge about how they interact with teeth. This paper is focused on the development of a Finite Element Method (FEM) model to be used in the optimization process of geometrical attributes of removable aligners. The presented method integrates Cone Beam Computed Tomography (CBCT) data and optical data in order to obtain a customized model of the dental structures, which include both crown and root shapes. The digital simulation has been focused on analyzing the behavior of three upper frontal teeth. Moreover, the analyses have been carried out by using different aligners’ thicknesses with the support of composite structures polymerized on teeth surfaces while simulating a 2 degrees rotation of an upper central incisor.

Abstract:
In this paper, a new prototype is proposed for accelerated orthodontic tooth treatment. In contrast to conventional methods, where heavy vibration generators are used, the proposed design is light and small and may remain into patient’s mouth without obstructing his daily activities. To do that, a PVDF Piezoelectric actuator layer is incorporated into a bio-compatible flexible structure which is to be excited by an external electric source. Generally, application of cyclic loading (vibration) reverses bone loss, stimulates bone mass, induces cranial growth, and accelerates tooth movement. This reduce the pain experience and discomfort associated with the treatment and also enhances the patient compliance with the treatment. Vibration has the advantage of minimal side effects in comparison to medicinal treatments. This configuration enables the operator to adjust the vibration frequency as well as the orthodontic force exerted on the tooth.
