Care should be taken for grafts not to be overfilled to avoid exposure due to soft tissue shortage. Primary closure of the flaps is desirable. There should be no voids between the buccal and the lingual flaps or part of the graft material will be exposed. Excessive suture tensions should not be placed on flaps to avoid necrosis. Mattress sutures are the most suitable ones since they minimize contact of the suture material with the graft which will in turn minimize oral bacteria from coming in contact with the graft by capillarity.
Synthetic sutures are better than silk because they have less capillarity.
Radiographically, it cannot be said that true regeneration took place. Clinically, treated lesions are evaluated in terms of pocket depth and attachment level. A previous pocket which does not probe after treatment is considered a success. True periodontal regeneration could only be confirmed by histologic evaluation which, for obvious reasons, cannot be routinely done. Since this was a research case, a reentry surgery was performed.
