Pages 109-120, Language: EnglishMellonig / TriplettThis paper presents an evaluation of the use of the principles of guided tissue regeneration to correct the osseous defects associated with the placement of dental implants. The biologic rationale for the use of supplemental materials, such as decalcified freeze-dried bone allograft, is discussed. The results of this investigation suggest that the use of a physical barrier in combination with a bone allograft can produce successful results in 97% of the defects treated.
