These data suggest that Le Fort I internal distraction for severe cleft maxillary deficiency leads to better dental occlusion, less relapse, and better speech results.
Harvest of the autogenous iliac crest bone graft for an alveolar cleft defect (the gold standard) may cause short- and long-term pain and sensory disturbances. To determine if a tissue engineering technique with similar bone healing results offered decreased morbidity, we compared techniques for postoperative donor site pain. Traditional iliac crest bone graft had more donor site complications compared with both tissue engineering and minimally invasive iliac crest bone graft. With donor site pain, traditional had the most patients with pain and tissue engineering had the least patients with pain at all time points. The mean pain score, including both intensity and pain frequency, was greatest at all time points in traditional and least at all time points in tissue engineering. Closure of alveolar cleft defects with a resorbable collagen sponge and bone marrow stem cells resulted in reduced donor site morbidity and decreased donor site pain intensity and frequency.
Rapid palatal expansion using a bone-borne distraction device in cleft patients with transverse maxillary hypoplasia who have failed nonsurgical orthodontic expansion provides adequate expansion necessary for alveolar bone grafting and stable results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
