title: Defect morphology: effects on regenerative predictability and membrane selection.
abstract: In clinical experience, guided tissue regeneration has been associated with complications, which include membrane exposure. The maintenance of a stable blood clot under the membrane is key to a successful regenerative outcome. This requires adequate membrane stabilization, tension-free suturing, and maintenance of a good vascular supply to the defect. Careful selection of defects after a thorough periodontal evaluation and modification of surgical techniques from those used for conventional resective procedures can lead to predictable outcomes for guided tissue regeneration.
