title: [Clinical study of pure titanium membranes in oral implant surgery].
abstract: OBJECTIVE
  To evaluate predictability and treatment outcome of the pure titanium membranes in bone defects around endosseous implants.
  
  
  METHODS
  81 patients and 92 dental implants were included in this study. The defects around implants were filled with bone grafts and Bio-Oss, and then covered by titanium membranes. 6 - 10 months later, all of the membranes were removed.
  
  
  RESULTS
  5 patients showed complications in soft tissue healing with exposure of the membranes. Bone defects around 89 implants were successfully covered with new regenerated bone.
  
  
  CONCLUSIONS
  Pure titanium membranes show excellent biocompatibility, exhibit good mechanical properties, avoid grafts displacement, ingrowth of connective tissue and contour collapse.
