Abstract
If dental ankylosis occurs in maxillary incisors of a growing child, the ankylosed tooth can not move vertically with the subsequent disturbance in vertical growth of the alveolar process.
Because ankylosed tooth does not respond orthodontic force, extraction was recommended in the past. But the loss of tooth and accompaning alveolar bone loss incur compromised esthetic situation. And it is very hard to replace by prosthetics.
So intentional surgical luxation and orthodontic movement was attempted, but usaafy this approach is followed by recurrence of the ankylosis. Nowadays the unitooth subapical osteotomy and rapid movement of block bone was reported.
Two cases are presented, one is treated by intentional luxation and the other is by unitooth subapical osteotomy following application of light continuous force soon.
