Advancement of the anterior maxilla by distraction (case report)

Anterior segmental distraction osteogenesis in the hypoplastic cleft maxilla: report of five cases

“…8,10,19 The distractor used in this case series had the advantage of easy fabrication, minimal expense and good patient tolerance.…”

Anterior maxillary segmental distraction for correction of maxillary hypoplasia and dental crowding in cleft palate patients: a preliminary report

“…The results show that the premaxilla moved antero-superiorly, the soft tissue profile also improved, the length of the palatal plane and maxillary arch increased, and sufficient space was gained to align the crowding teeth. In 2004, KARAKASIS et al 15 presented a case report of gradual distraction osteogenesis using two intraoral bone-borne unidirectional devices of Zür-ich pediatric ramus distractor for anterior maxillary segment advancement. The patient achieved satisfactory final occlusion and considerable aesthetic improvement.…”

“…Similar results have been noted in other AMSD studies. 1,13,15 Possible reasons are that the muscles of the velopharynx are not affected by anterior maxilla advancement, and the velopharyngeal closure remains intact.…”

“…7 Subsequently, clinical researchwas carried out to determine the optimal protocols for AMSD. 1,3,9,10,13,15 In this paper, the authors present their preliminary clinical results for correction of maxillary hypoplasia and severe dental crowding secondary to CLP by advancement of the anterior maxillary segment using two types of distraction devices. The effectiveness, advantages, and disadvantages are discussed.…”

Maxillary Anterior Segmental Distraction Osteogenesis with the Dynaform System for Severe Maxillary Retrusion in Cleft Lip and Palate

“…10 Because the patient they presented had not undergone secondary bone grafting, two intraoral cylindrical distractors were applied to each segment. The distraction osteogenesis using an intraoral cylindrical distractor is as well known 11.…”
