[Management of incisor supraclusion]

The orthopaedic treatment of incisor supraclusion is possible by ingression of the superior incisors under both following conditions: the ingression to be obtained should not be superior to 8 mm, and there is a strong assumption that restitution of normal labial and lingual functions will be simultaneously obtained and especially a good labial competence in function and at rest. Dr Burstone's technique of incisor ingression uses an appliance operating only on the superior dental arch with light and constant forces which can be precisely adjusted. F.E.O. is only exceptionally required for maintenance of the posterior fixation.
