Regeneration of bone graft donor sites

When crestal volume is greatly insufficient for the placement of dental imp lants, bone grafting is usually the most reliable ridge augmentation proced ure. The grafts are most often taken in parietal or mandibular symphysis re gions. Though not too noticeable, it seems contra-indicated and even potent ially dangerous to leave zones like the cranium to repair spontaneously. Gu ided bone regeneration techniques have shown their ability to regenerate ne w bone under difficult conditions in jaws. Their use in bone graft donor si tes is simple and the results are consistent. This report shows that 2 type s of resorbable membranes are equally as efficacious in terms of new-bone f ormation.
