    Abstract:
    Cleft lip and palate patients often present maxillary retrusion and class III malocclusion after cleft repair. Maxillary distraction is a technique that can provide simultaneous skeletal advancement and expansion of soft tissue. Twelve patients with cleft maxillary deficiency due to cleft lip and palate were treated by Le Fort I osteotomy and two intraoral distraction devices that were activated after 4 days of latency period, 1mm per day on both sides. Long-term clinical and cephalometric evaluation of one and two years demonstrate stable results concerning the skeletal, dental and soft tissue relations. In this paper we discuss the advantages of distraction osteogenesis as a method for treatment of maxillary deficiency in cleft patients in terms of stability and relapse. The indications for maxillary distraction: (1) Moderate and severe retrusion that needs large advancement as in cleft lip and palate patients. (2) Forward and downward lengthening of the maxilla with no need for intermediate bone graft. (3) Growing patients. In conclusion, maxillary distraction in moderate or severe retrusion, as in cleft patients offers marked maxillary advancement with long-term stability.
