Clinical study on a surgically assisted rapid orthodoontics using dentoalveolar distraction osteogenesis

ABSTRACT

treatment outcomes after surgically assisted rapid tooth orthodontics using the corticotomy and dentoalveolar distraction osteogenesis technique. In a total of 78 patients, We have performed surgically assisted rapid tooth movement in the department of oral and maxillofacial surgery and orthodontics, Wonkwang university from January in 2000 to December 2002. They were classified into 4 types, type I has categorized as anterior segmental protraction, anterior segmental retraction and tooth or dentoalveolar segment mesiodistal movement cases, type II cases included in tooth or dentoalveoalr segment bucco-lingual movement, rapid palatal expansion and mandibular symphysis widening, type III in anterior dentoalveolar segment intrusion, posterior tooth or dentoalveolar segment intrusion and molar uprighting cases and finally type IV was included in vertical alveolar distraction and mandibular lengthening cases. We have investigated results according to treatment options, indications, orthodontic strategy and final complications. As a results, these techniques are very useful and effective in cases of difficult tooth movement in adult orthodontics, and even in dentofacial deformities by way of dentoalveolar corticotomy and distraction osteogenesis. There were few intraoperative or postoperative complications and were not clinically significant.
