title: Histomorphometric analysis of delayed implantation after horizontal distraction osteogenesis of the mandible in dogs.
abstract: OBJECTIVE
  Insufficient alveolar width is known to impede successful implantation and is a major obstacle to successful oral reconstruction using intraosseous implants. The aim of this study was to evaluate the osseointegration at implantation after consolidation in distracted narrow alveolar bone.
  
  
  METHODS
  Three adult mongrel dogs weighing 9 to 10 kg were studied. The lower premolars were extracted and horizontal distraction was performed using a distraction device after 8 weeks. Eight weeks after consolidation period, SLA surface implants were installed. The dogs were killed after 4 weeks implantation.
  
  
  RESULTS
  The preoperative and postoperative buccolingual widths of alveolar ridge were 2.7 ± 2.1 mm and 4.8 ± 2.5 mm, respectively. Direct bone contact was achieved, with no significant difference in new bone formation observed between implants placed in the distracted and undistracted bone after 4 weeks.
  
  
  CONCLUSIONS
  It was concluded from this study that horizontal distraction is a useful technique in augmenting a narrow alveolar ridge necessary for implant placement.
