Orthognathic treatment and aligners, which protocol?

Abstract

Introduction : Les technologies numériques dentaires de conception, simulation et fabrication sont en constante évolution. Il est possible de simuler numériquement des mouvements dentaires, ainsi que des déplacements des deux arcades et de réaliser des gouttières thermoformées fabriquées à partir de cette simulation. Objectif : Les auteurs présentent le couplage de la numérisation 3D intra-buccale avec la radiographie 3D de basses doses d'irradiation qui permet de réaliser un setup chirurgical très précis, de préparer des gouttières de repositionnement et de fabriquer des plaques d' ostéosynthèse. Le protocole de prise en charge orthodontico-chirurgicale par aligneurs utilisé par le premier auteur sera décrit en détail. Matériels et méthodes : Les auteurs présentent, au travers des cas cliniques exposés, les progrès réalisés en chirurgie orthognathique grâce à la 3D et au système des gouttières thermoformées Invisalign ® . Résultats : En observant les trois cas cliniques présentés, on peut constater que la durée moyenne de traitement était bien inférieure à la durée moyenne des protocoles orthodontico-chirurgicaux traditionnels.

Major considerations and clinical outcomes of aligner plates in orthodontic treatments to achieve dental harmonization: a concise systematic review

“…The articles selected in the present study showed that the aligners are created by computer software, require only one impression, require few complementary exams, and allow excellent predictability of the treatment, when used within their indications [1,2]. They have a satisfactory aesthetic level, are comfortable, easy to clean, cause less trauma when compared to conventional fixed appliances, are less uncomfortable for patients since they can be removed and placed back without difficulty by the patient, and demonstrate excellent results.…”

“…There are numerous options involving technologies that serve people of the most varied ages and lifestyles. Among them, the aligner plates are ideal for those who want to correct imperfections in the dental position [1]. The aligner plates are transparent acetate orthodontic appliances, used to harmonize the smile through the movement of the teeth.…”

“…The aligner plates are transparent acetate orthodontic appliances, used to harmonize the smile through the movement of the teeth. In addition to being completely transparent, and not affecting aesthetics, these plates can be removed so that the patient can have his meals free of any interference and discomfort [1,2].…”

“…A digital model is printed in 3D and over it, the plate is stamped with all the necessary activations so that the treatment can be performed with greater precision and comfort. An average of 20 pairs of plates are used throughout the entire treatment, which must be planned by a specialized orthodontist [1][2][3].…”

Effectiveness and Efficacy of Thermoformed and 3D Printed Aligners in Correcting Malocclusion (Spacing) and Its Impact on Periodontal Oral Health and Oral Microbiome: A Double-Blinded Parallel Randomized Controlled Multicenter Clinical Trial

“…A recent randomized clinical trial confirmed that treatment duration and chair time in mild-to-moderate cases appear to be significantly short over conventional systems [ 19 ]. There is also a lack of evidence on the use of aligners in space closure and its impact on periodontal health [ 20 ]. There is a need for evidence in conducting well-designed clinical trials.…”
