Abstract:

Summary： After the use of second alveolar bone grafting， bone resorption is a common complication. The insufficiency of bone volume is proved to be a handicap to the stages of team approach afterwards. How to reduce or to avoid bone resorption is a hot spot in the study of the treatment for alveolar cleft. In the past years many scholars have applied guided tissue regeneration to alveolar cleft repair， including the use of secondary alveolar bone grafting in conjunction with barrier membranes to evaluate the outcome of reducing graft bone resorption， and the barrier membranes without bone grafting to appraise the effect and feasibility in bone regeneration. They also did some comparative studies and discussed how to choose membrane when applying it to alveolar cleft repair. In this paper， the study on using guided tissue regeneration to repair alveolar cleft is reviewed.

Key words: alveolar cleft, guided tissue regeneration, bone grafting
