Les appareils amovibles ont représenté pendant longtemps le moteur de la thérapeutique fonctionnelle
La notion de la thérapeutique orthopédique fonctionnelle ne limite pas son action aux seules régions adjacentes aux arcades dentaires, mais qu’elle intéresse l’appareil dento-maxillo-facial dans sa totalité jusqu’aux régions plus lointaines de l’organisme, n’est pas d’acquisition toute récente.
Son objet est de modifier la morphologie de l’appareil dento-maxillo-facial en construisant une architecture osseuses plus adaptée à la fonction et à l'esthétique.

Mandibular Symphyseal Distraction Osteogenesis and SARPE aao 2018 Washington ...Dr Sylvain Chamberland
SARPE and Mandibular Symphyseal Distraction Osteogenesis
Transverse skeletal deficiency is a common clinical problem associated with narrow basal and dentoalveolar bone. Bimaxillary transverse distraction osteogenesis for correction of OSA was first reported by Conley & Legan (2006). Mandibular symphyseal distraction osteogenesis (MSDO) evolve form tooth anchor device to bone anchor device for a better control of the distraction segment in the 3 planes of space. Its success depends on good collaboration between the orthodontist and the surgeon, and on strict patient selection. Throughout case reports, we will review the diagnosis, orthodontic and surgical treatment planning considerations to achieve clinical success.
Learning objective:

Objectifs − Évaluer le rôle de l’âge sur la régénération osseuse par remodelage au niveau de la symphyse après génioplastie.
Méthode − Cinquante-quatre patients ayant bénéficié d’une génioplastie à la fin de leur traitement orthodontique ont été divisés en trois groupes selon leur âge au moment de l’intervention : moins de 15 ans (groupe 1), 15 à 19 ans (groupe 2) et 20 ans ou plus (groupe 3). Le groupe contrôle est constitué de 23 patients n’ayant pas désiré de génioplastie, suivis radiographiquement deux années après la fin de leur traitement. Les patients ont été évalués à trois moments : juste avant l’intervention (T1), juste après l’intervention (T2) et deux ans après l’intervention (T3).
Résultats − La quantité d’avancement mentonnier est identique pour les trois groupes, mais la quantité de remodelage osseux est plus importante pour le groupe 1, un peu moins notable pour le groupe 2 et encore moins pour le groupe 3 que pour le groupe 2. Pour les trois groupes, l’épaisseur de la symphyse a considérablement augmenté dans les deux années qui ont suivi l’intervention, mais la quantité d’os néoformé est bien plus importante dans le groupe 1 que dans le groupe 3. Le remodelage osseux, aussi bien au-dessus que derrière la symphyse déplacée, est également plus important chez les plus jeunes du fait de la croissance verticale des procès alvéolaires. Il n’y a aucune preuve d’un quelconque effet délétère de la génioplastie sur la croissance mandibulaire.
Conclusion − La génioplastie avec déplacement du segment mentonnier vers le haut et vers l’avant permet d’accroître l’épaisseur de l’os symphysaire, par apposition osseuse au-dessus du point B, ainsi qu’au niveau du point Gnathion. Lorsqu’elle est indiquée, la génioplastie doit être réalisée avant l’âge de 15 ans pour générer les meilleurs résultats en termes de remodelage osseux.
Objective: To evaluate the role of age as a moderator of bone regeneration patterns and
symphysis remodeling after genioplasty.
Method: Fifty-four patients who underwent genioplasty at the end of their orthodontic treatment
were divided into three age groups: younger than 15 years at the time of surgery (group 1), 15 to
19 years (group 2), and 20 years or older (group 3). Twenty-three patients who did not accept
genioplasty and had a follow-up radiograph 2 years after the end of their orthodontic treatment
were used as a control group. Patients were evaluated at three time points: immediate preoperative
(T1), immediate postoperative (T2,) and 2 years postsurgery (T3).
Results: The mean genial advancement at surgery was similar for the three age groups, but the
extent of remodeling around the repositioned chin was greater in group 1, less in group 2, and still
less in group 3. Symphysis thickness increased significantly during the 2-year postsurgery interval
for the three groups, and this increase was significantly greater in group 1 than in group 3.
Remodeling above and behind the repositioned chin also was greater in the younger patients. This
was related to greater vertical growth of the dentoalveolar process in the younger patients. There
was no evidence of a deleterious effect on mandibular growth.
Conclusion: The outcomes of forward-upward genioplasty include increased symphysis
thickness, bone apposition above B point, and remodeling at the inferior border. When indications
for this type of genioplasty are recognized, early surgical correction (before age 15) produces a
better outcome in terms of bone remodeling.

Management of Class II correction device.
Lecture presented at McIntyre joint plenary program for doctors at the 66th Annual scientific session of the Canadian Association of Orthodontists, Montréal, september 2014
Class II correction devices are commonly used in orthodontics and exist in many declension. Literature reviews show that such devices do not appear to cause any significant changes in mandibular length and their effectiveness in correcting class II malocclusion can be explained by a combination of some skeletal (mainly maxillary) and dentoalveolar (maxillary and mandibular) modifications. The SUS2 corrector device will be presented using bondable head gear tube and self-ligating mandibular molar tube. A case presentaion will be used to explain how to use SUS2 device in a successful manner.

Sarpe (2 stages) vs le fort 1 (single stage) approach to complex maxillary de...Dr Sylvain Chamberland
Orthognathic surgery seeks to correct maxillofacial deformities often associated with significant functional impairment. Procedures to alter the relationship of the jaws and teeth include osteotomies of the maxilla, mandible and chin. An understanding of the evolution of the principles and practices, combined with knowledge of recent advances in surgical technique and technology, helps the clinician effectively treat challenging problems. Interdisciplinary treatment planning, backed by strategies to manage complications, are necessary components of effective Orthognathic surgery.
