RESUMO
Author explains an orthodontic appliance which permits uprighting of horizontal impacted mandibular second molar teeth, associating a mandibular anchorage and an uprighting auxiliary spring. The anchorage consist in a Mollin lower lingual arch. The auxiliary spring will upright the tooth in two steps. First one, it will induce a distal movement of the second molar. Second one it will induce the crown tipping. The significant benefit of this appliance is to permit an only orthodontic approach, without necessity of any surgical assistance.

Excessive cartilage growth on the condyle process of the mandible can result from primary hyperreactivity of the growth cartilage or be a secondary adaptation to an imbalance in occlusive and/or cervicofacial conditions. Treatment depends on the distinction between these two forms. Primary active overgrowth is treated by condylectomy sparing the distal apparatus although conservative surgery to re-centering the temporomandibular joint and re-establish symmetry without condylectomy may be used in quiescent moderately active forms saving the joint. For secondary forms, the joint is re-centering and symmetry is re-established without condylectomy. If started early enough, orthopaedic treatment can avoid the development of secondary forms resulting an imbalance in occlusive and/or cervicofacial conditions.

Orthodontic preparation before orthognatic surgery must straighten teeth alignment to enable correct adaptation of the upper and lower arches. It must also rectify dento-alveolar abnormalities partially responsible for the dysmorphosis and which can hinder smooth articulation of the bones. Thus before and after the operation, the orthodontist will have to prepare and monitor the surgical splints used in posterior deficiencies.

Posterolateral segmentary maxillary impaction osteotomy has a role to play in the treatment of gaps between the upper and lower jaws. It has several advantages, especially an uncomplicated postoperative period and the single-maxillary contention it provides. The indication must be established after an articulator assessment in order to take into account the mandibular protrusion caused by autorotation and to prevent a sagittal shift. Associated marginal glossectomy will frequently be required. Similarly, in case of vertical excess, genioplasty for vertical reduction will improve the facial balance. This technique may also be proposed as "pre-prosthetic surgery" in cases of egression in the premolar and molar areas, for which it has shown excellent results.
