[Flap techniques in secondary alveoloplasty: a comparison between two types of flap].
BACKGROUND
The aim of this study was to compare two surgical soft tissue coverage techniques of secondary alveolar grafts in cleft lip and palate patients: the gingival mucoperiostal slidind flap and the mucosal rotation flap.


METHODS
Fifty-two secondary alveolar bone grafts were retrospectively included in the study. Four clinical parameters were evaluated: post-operative dehiscence, oro-nasal fistula relapse, canine eruption through the graft and postoperative secondary periodontal procedures.


RESULTS
Gingival mucoperiostal flaps had less postoperative dehiscence, more fistula relapse and needed less secondary periodontal procedures.


CONCLUSIONS
Based on this study and on literature data, gingival mucoperiostal flap provides better quality of soft tissue coverage. Flap design doesn't influence canine eruption. Bone graft complications are increased with poor oral hygiene, if canine eruption occurred before surgery and in older patients.
