Abstract　： [Introduction] Granular artificial bone graft materials such as hydroxyapatite and tricalcium phosphate are frequently used for the recovery of tissues lost as a result of periodontal diseases. These materials have been reported to have good biocompatibility, to be relatively inexpensive and to have excellent handling ability. On the other hand, they are associated with certain basic problems: poor ability to form new attachment, inability to actively induce bone formation, difficulty in achieving morphological formation in complicated bone defects, and delayed healing due to leakage or outflow of granules from the postoperative root surface and the gingival flap or sutured site. Some reports have noted that if outflow of the granules could be prevented as soon as possible, it would increase the attachment gain and decrease the gingival recession, leading to possible improvement in the outcome. On the other hand, some reports have already described ways to protect against a granule leakage. Takei et al. developed the papilla preservation technique by improving incisive suturing of the conventional flap procedure, and reported its usefulness.
