L'extraction en orthodontie: quand et pourquoi?

During the last century orthodontic treatment philosophies changed continuously. The necessity to extract teeth in order to correct a lack of space has many times been the subject of discussion. In fact there exists several techniques which make it possible to avoid extractions in many cases. A number of criteria which influence the decision to extract or not, as well as some techniques to regain space in upper and lower arch are discussed

Indications de la chirurgie orthognathique, limites de l'orthodontie et de la chirurgie.

The different sagittal, vertical or transversal skeletal dysmorphosis can be treated with orthodontic or orthopaedic appliances. Certain limits of treatment will be due to the age of the patient, the importance of the skeletal dysmorphosis, technical limits of the orthodontic appliances or the motivation and compliance needed from the patient. For this reason an orthodontic treatment combined with orthognathic surgery may be indicated. Nevertheless the combined orthodontic-surgical treatment has also its limitations and specific treatment needs from orthodontist and maxillo-facial surgeon

La prise en charge primaire et secondaire des fentes labio-palatines au centre labio-palatin de Bruxelles.

Since 1987, we chose a neonatal repair of the cleft lip and nose and closure of the cleft palate at 3 months of age. Ventilation tubes are systematically inserted in the drums at time of palatoplasty. Alveolar clefts are grafted when canine erupts. Secondary correction, which might be early, are scheduled according to functional, aesthetic or psychological demands. A interdisciplinary follow-up by a stable and united team is essential for an adequate management of sequels.Depuis 1987, nous avons opté pour une correction précoce néonatale de la fente labio-narinaire et une fermeture de la division palatine à l’âge de trois mois. Des drains trans-tympaniques sont systématiquement placés lors de la palatoplastie. Les fentes alvéolaires sont comblées lors de l’éruption de la canine. Les corrections secondaires, qui peuvent être précoces, sont programmées en fonction des demandes fonctionnelles, esthétiques ou psychologiques. Un suivi interdisciplinaire par une équipe stable et soudée est essentiel pour une prise en charge correcte des séquelles

Objectifs orthodontiques pré- et post-chirurgicaux et préparation orthodontique.

Orthodontics in combination with orthognathic surgery is a possibility today for correcting sagittal, vertical and transversal dysmorphosis. To do this, orthodontic preparation before surgery is necessary. In the sagittal plane, dental compensations should be removed. In the vertical plane, levelling of a severe mandibular SPEE curve should be accomplished postsurgically, and transverse coordination obtained. Orthodontic preparation is very specific to the type of dysmorphosis: class II malocclusion, class III malocclusion or in open bite. Postsurgical orthodontic treatment is used to finalize tooth alignment as in conventional orthodontics
