New Approach for Midface Hypoplasia in Cleft Lip and Palate Patients

Purpose : To introduce a more effective and efficient protocol for protraction of maxillary complex in CLP patient and demonstrate it by case presentation. Methods : Miniplates are placed on zygomatic buttress and anterior part of mandible, at the time of secondary alveolar bone graft. During the night time, the orthopedic force is applied by wearing elastics from maxillary miniplates to facemask (500 g per side). During the day time, theintermaxillary elastics connecting maxillary miniplates to mandibular miniplates are applied (200 g perside). During the orthopedic treatment, dental alignment is possible. Results and conclusion : By the new protocol, the intermaxillary relation and occlusion are improved due to the stable intraoral anchorage and better cooperation of patients.
