Ortodoncia Digital. Sistema de Alineación Mediante Placas Transparentes: caso clínico / Digital orthodontics. Alignment system using transparent plates: a clinical case

El tratamiento ortodóncico permite rehabilitar la función como también la estética facial y de la sonrisa. En muchos casos, esto puede realizarse sin la utilización de brackets. Las placas alineadoras realizan movimientos en las arcadas dentarias y las posibilidades y los resultados obtenidos cada vez son mejores. La utilización del sistema de alineación con placas permite que muchos pacientes, que no están dispuestos a utilizar brackets, encuentren una respuesta a sus problemas de oclusión (AU)

Clear aligner therapy: risks and clinical strategies / 中华口腔医学杂志

Clear aligner, as a transparent and removable appliance, offers an alternative to conventional fixed appliance to patients with high demands for esthetics and comfort. Meanwhile, the rapid development of materials and techniques has made clear aligner more widely used in orthodontics. However, there are still several concerns and risks in clinical practice of clear aligners, which may result in unfavorable outcomes. Herein, we have discussed the clinical risks of clear aligner therapy, and provided some targeted strategies, in order to promote the clinical application of clear aligners.

Application of digital technology in orthodontic clinic / 口腔疾病防治

@#The rapid development of digital technology has made the processes of orthodontic data collection, diagnosis, design and treatment more accurate, comprehensive, convenient and safe and has improved the clinical efficiency of orthodontists. Safe, non-invasive, rapid three-dimensional facial imaging and digital dental models have enabled orthodontists to collect accurately visualized case data. In addition, during diagnosis and design, orthodontists can comprehensively analyze teeth, jaws, and cranial surfaces in 3 dimensions. Through advances that range from digitized whole-dentition information to computer-replicated design and computer-aided manufacturing, invisible orthodontic technology without brackets has become one of the best manifestations of the combination of digital technology and oral orthodontics. In addition, individualized fixed orthodontic devices have become widely used in orthodontic clinics. In this paper, the applications of digital technology in orthodontic clinics is described. It is hoped that orthodontists will be able to use digital technology rationally to benefit increasing numbers of patients with orthodontic demands.

Application of an individualized appliance in orthodontic treatment / 口腔疾病防治

@#More than 20 years have passed since the advent of individualized appliances, which are designed according to the corrective target position. Through a series of digital technology-aided design and production processes, individual appliances have been increasingly recognized and accepted by the public. At present, there are three types of individualized orthodontic appliances: individualized lingual orthodontic appliances, non-bracket invisible appliances and individualized labial appliances. Because of their good effects in orthodontics, these appliances have gradually become mainstream orthodontic treatment tools. However, many doubts persist regarding their use in clinical treatment. This article reviews the development history, design principles and characteristics of the three types of individualized appliances. The results of a literature review showed that CAD/CAM and CBCT provide a hardware foundation for personalized orthodontic appliances that simplifies the therapeutic process. Additionally, individualized appliances also place higher demands on orthodontists. This article could provide references for and help with the clinical selection and use of individualized appliances.

Factors related to the control of maxillary anterior teeth torque in invisible appliances / 口腔疾病防治

@#Invisible appliance technology is a novel orthodontic technology that uses computer aided design and polymer materials to achieve a more aesthetic and comfortable treatment. Compared with traditional lip-bracket orthodontic treatments, the greatest advantages of an invisible appliance are aesthetics. In the orthodontic process, the control of the anterior teeth may not be accurate, which often directly affects the patient′s postoperative side appearance; however, in clinical practice, there is still a large deficiency in the control of the anterior tooth torque by an invisible appliance compared to traditional lip-bracket orthodontic treatments. The factors related to the expression efficiency of anterior tooth torque include the combination of morphology and position of different types of brackets and wires, the tooth movement mode and clincheck design. This article reviews the factors that influence lingual orthodontics and clear aligner therapy in the treatment of anterior tooth torque.

Invisible orthodontics: clear aligners and customized lingual appliances / 中华口腔医学杂志

In recent years, invisible orthodontics has been one of the concerns of both orthodontists and patients. As two types of invisible orthodontics, clear aligners fit for cases that have high demand for living quality, need distalization of molars or intrusion of incisors, suffer from severe periodontitis, or that have non-abundant time for visits. While customized lingual appliances fit for cases that have high demand for aesthetics, have deep overbite or complex malocclusion, need maxillary expansion or retraction of incisors, or that have low compliance and good economic conditions. Based on aspects of clinical application, this article presents the characteristics of these two types of invisible orthodontics, in order to provide reference for individualized options according to different situations.
