Introduction: In 85% of orthodontic patients, lingual dyspraxias are present and may justify orofacial myofunctional rehabilitation because of their morphogenetic potential. The objective of this literature review is to search for scientific arguments corroborating or not the relationships between dysmorphias and the static, dynamic labio-lingual-jugal balance during functions and parafunctions.

Material And Method: A review of the literature was carried out by keywords on PubMed.

Introduction: The prevalence of lingual dyspraxia is high but not all patients require management by a physical therapist. The aim of this article is to propose a decisional flow chart separating, via diagnostic criteria, patients who can be managed in office from patients requiring oromyofunctional rehabilitation by an oro-myo-functional rehabilitation (OMR) professional and to provide, if necessary, simple exercise sheets.

Material And Method: An expert, a maxillofacial physiotherapist from the Fournier school, has proposed, based on the literature, her experience as a clinician and in consultation with orthodontists, different criteria for the severity of dyspraxia as well as exercises to be implemented for cases that are manageable in the office.

Introduction: The aim of the study was to assess the time factor and tooth type during premature debond of orthodontic brackets.

Material And Method: A retrospective epidemiological study was carried out on adolescents who had benefited from a multi-metal vestibular attachment treatment, having all 6 to 6 teeth bonded to the arch on the day of installation.

Results: 333 patients were included.

[Third molars in the orthodontic therapeutic decision].

Introduction: Despite a high prevalence of agenesis, third molars should frequently be considered in our orthodontic treatment plans.

Material And Method: The aim of this study was to describe, according to the literature, the therapeutic possibilities of third molar management.

Results: The avulsion isn't systematic.

[Bisphosphonates: how to proceed in orthodontics].

Introduction: Bisphosphonates are mainly used in the treatment of osteoporosis and in oncology. They bind to bone and inhibit the action of osteoclasts, leading to a decrease in bone remodeling and thus hindering tooth movement. The main objective was to present, through a review of the literature, the indications and therapeutic modalities for orthodontic treatment of patients who are or have been treated with bisphosphonates.

[Does positional plagiocephaly affect the need for orthodontic treatment, and the mandibular and occlusal symmetry?].

Introduction: Positional plagiocephaly (PP) is characterized by an asymmetrical flatness of the posterior part of the skull which may involve the frontal part of the skull and the face. The aim is to assess whether children and adolescents with PP have more occlusal and skeletal asymmetries and whether the need for orthodontic treatment is greater than in the healthy population.

Material And Method: A comparative cross-sectional epidemiological study was carried out.

[Comparative study of two software for the detection of cephalometric landmarks by artificial intelligence].

Introduction: Manual, tedious cephalometric analyzes of a lack of productivity (errors in plotting and measurement) making the prospect of a fully automated algorithm turning out attractive. The objectives of the study were to evaluate the positioning (accuracy and precision) of common landmarks by two software programs offering detection by artificial intelligence (WebCeph™ and DentaliQ®) compared to a manual reference and then to the comparators.

Materials And Methods: 68 lateral cephalograms were selected, 22 landmarks were distributed manually and then the differences between this gold standard and the points detected by each software were measured, as well as the success detection rate (SDR).

Due to many innovations, bonding in the sense of bracket positioning is continually remodeling itself. Therefore, we wanted to define what a good bonding was and how to achieve it, both by identifying factors that could alter it and by evaluating the bonding assistances currently available. We carried out the synthesis of 65 comparative studies from PubMed.

The relevance of Class II interceptive therapy is controversial. The objective of this literature review was to note its indications and if a benefit is proven. We carried out a systematic search on PubMed from 1999 to 2019 by keywords on randomized trials.

[Miniscrews during the retention phase: indications, therapeutic means and effects].

Even if miniscrews are mainly used in the active phase, their uses during the contention have been reported for a few years either by installation of miniscrews de novo or by taking advantage of miniscrews inserted during the active phase. The objective of this article is to describe the uses - reported in the literature - of miniscrews during the retention phase. We have conducted a research from the database PubMed with keywords associations.

The objective of this case series was to show how only one miniscrew can be used to treat simultaneously or successively canine impaction and different malocclusions. Three patients aged of 13 years old who had malocclusions, such as Class II, overbite and canine impaction, were each one treated with the same miniscrew throughout the treatment period. Palatal miniscrews were placed mesially to the first molar and used as a direct or indirect anchorage depending on the moment of the treatment.
