Zur Indikation der Ausgleichsextraktion beim kieferorthopädischen Lückenschluß im Frontzahngebiet

This follow-up study presents patients who underwent orthodontic space closure in the maxilla after traumatic loss of frontal teeth or aplasia of a lateral incisor. Comparison covers findings obtained from casts and cephalograms in 24 patients with or without compensatory extraction. The findings indicate that acceptable results regarding axial tooth positioning and profile can be obtained without compensatory extraction, Prerequisites are distal occlusion of the first molars by one premolar width and continuous monitoring for regular overbite and uncrowded lower incisors. If orthodontic space closure can be achieved only by compensatory extraction, the indication for this space closure procedure calls for even more critical judgement.
