title: Secondary closure of alveolar cleft with resorbable collagen membrane and a combination of intraoral autogenous bone graft and deproteinized anorganic bovine bone.
abstract: OBJECTIVE
  Secondary alveolar bone grafting is a method that enables an excellent oral rehabilitation of the patients having alveolar cleft. The aim of this work is to report the closure of the alveolar cleft with the use of harvested autogenous bone graft combined with deproteinized anorganic bovine bone (Bio-Oss) under local anesthesia.
  
  
  METHODS
  Nine patients with age range, 8-11 years were consulted for their unilateral alveolar cleft.
  
  
  METHODS
  A combination of symphyseal bone and deproteinized bovine bone mineral (DBBM) was placed into the alveolar cleft defect. Clinical and radiographical assessments were performed at 1, 3, and 6 months postoperatively.
  
  
  RESULTS
  The healing period was uneventful in all cases, and no complications, such as membrane exposure, infection, or harvest site morbidity, were observed. All treated defect sites exhibited excellent bone formation, with an average of 5.45 mm (range, 2-9 mm; standard deviation 1.93 mm) of augmentation achieved overall.
  
  
  CONCLUSIONS
  The treatment of vertically deficient alveolar ridges with guided bone regeneration using a mixture of autogenous bone and DBBM and resorbable collagen membrane can be considered successful, using this technique in an out-patient office setting.
