Since 1907, the international community has used Angle's classification to assess the mesio-distal relationships of the dental arches. It is the basis of the diagnosis of malocclusion in the sagittal dimension and indicates or not an orthodontic correction treatment. This work was aimed to inventory the classification methods of malocclusions used today. Indices of treatment need were also presented because they are based on one or more occlusal anomalies to indicate treatment. The classifications were criticized and the contribution of a functional analysis based on the use of the trilogy setting, centering and guiding was detailed. The type of anomalies (skeletal and dental) must be completed by the analysis of the occlusal anomaly of setting (centering or guiding) and of the category of occlusion (functional occlusion, functional malocclusion or pathogenic malocclusion), ie its possible pathogenic impact on orofacial structures. A consensus on the classification of occlusal anomalies is necessary in order to better identify the anomalies and their global repercussions, and to better define the needs for orthodontic treatment.

Objectives: The objectives of this systematic review were to assess the efficacy of transcutaneous electrical nerve stimulation (TENS) for the management of temporomandibular disorders (TMD) and to determine the indications and most appropriate application modalities.Methods: Papers published in the Medline database, EMBASE, and the Cochrane Library before November 2018 were included.Results: Fourteen articles were retained, corresponding to a total of 532 patients, among which, 285 had a TMD. Immediately after a TENS session, significant relief of pain (19.2% to 77%), significant functional improvement (mouth opening amplitude increased by between 8.7% and 19.46%), and reduced electromyographic activity of the anterior temporalis and masseter muscles were observed. However, studies comparing TENS to other physical medicine modalities (ultrasound and laser) reported equivalent results.Conclusion: Further randomized comparative clinical trials will be necessary to optimize the use of TENS (program, duration of sessions, duration of treatment) for different types of TMD.

The success is evidenced by the longevity of aesthetic and functional therapeutic result. The occlusal «postorthodontic¼ failure could result in dental instability, functional discomfort, dental or musculo-articular complaint. Analysis of the occlusion research potential occlusal pathogenic dysfunction listed in stabilizing (shimming), centering and guiding anomalies. The large capacity of tolerance of the masticatory system makes it difficult to define the border between physiology and pathology but it is necessary to have benchmarks that can be summarized as follows: - shimming: occlusal contact of mesio-lingual cusp of the first maxillary molars (in Class I, II or III) and occlusal contacts between the canines antagonists; - centering: no transversal deflected occlusion between maximal Intercuspation (ICP) and occlusion in Centric Relation (RCP); - guiding: absence of posterior interference, absence of anterior interference (locking).

These interventions usually aimed at the correction of the skeletal discrepancy by mandibular retrognatism with an advancement of the distal portion of the mandible after mandibular osteotomy. The position of the condyle is determined during the osteosynthesis with miniplates. Condyles are set back in relation with the supine position of the patient and the weakness of his (her) curarized muscle. All studies show that surgery of mandibular advancement causes a lateral, torque and backward movement of the condyles, all harmful to the condyles. Factors that predispose to condylar resorption are "the patient": a woman, young (between 15 and 40), high mandibular angle, with a history of temporo-mandibular disorders and surgical overload applied to the condyles. What are the possible solutions to avoid failures? Patient preparation before surgery and surgery simulation with an articulator, condylar position control during surgery, working with surgeons to achieve a condylar portion stabilization system (with the CAD), quickly set up a mobilization of the mandible by physiotherapy.

Our aim was to evaluate symphyseal distraction in relation to duration of expansion, and to propose an optimised procedure. Eighteen patients (mean (SD) age 19 (7) years) with transverse mandibular deficiency were treated by symphyseal distraction osteogenesis. The mean (SD) anterior dental crowding measured was 6.8 (4.2) mm. We retrospectively compared the width of expansion between the canines (ICE) and expansion between the first molars (IFME) after symphyseal distraction according to the distraction time. The median (range) duration of expansion was 13.6 (7-21) days. The median (range) ICE distraction width was 5.5 (3.4-8) mm and IFME width 3.3 (1-7.9) mm (p<0.001). There was a significant correlation between expansion width and distraction time (p<0.001). The transverse anterior and posterior expansion widths differed significantly until 14 days after expansion. The expansion ratio (ICE:IFME) decreased as expansion time increased. The results suggest that the duration of activated expansion can be predicted from the degree of incisal crowding using the formula: distraction time (days)=0.84+3.4×[IC (mm)]-0.2×[IC (mm)](2).

UNLABELLED: The aim of this exhaustive descriptive epidemiological study was to determine the clinical approach to be adopted by practitioners specializing exclusively in pediatric odontology and by orthodontists when confronted with decayed molars in children and adolescents. MATERIAL AND METHOD: A questionnaire was sent out to all corresponding practitioners (n=2076). Six questions related to treatment decisions taken when faced with decayed permanent first molars (unfavorable short or middle-term prognosis) in patients needing, or not, orthodontic care. The Chi(2) test was used to compare responses. RESULTS: Thirty-eight per cent of pedodontists (n=38) and 12.5% (n=246) of orthodontists answered the questionnaire. Faced with a permanent first molar with an unfavorable middle-term prognosis, 75.7% needed criteria to help them reach their treatment decision. In decreasing order of importance, these criteria were: presence of the third molar, patient motivation, inter-arch relationship, patient's oral hygiene, facial type, anterior jaw-teeth discrepancy and the number of molars to be extracted. Faced with a permanent first molar requiring extraction and when orthodontic treatment was not required, 31.7% of practitioners decided to close the maxillary space immediately as opposed to 13.4% who closed the space at the mandible. In the presence of a single decayed first molar, 68.7% of practitioners did not extract the antagonist or contralateral first molars. CONCLUSION: These treatment decisions were not always unanimous and call for a combined approach between dental surgeon and orthodontist.
