Abstract: Bilateral mandibular first molars of 36 rabbits were extracted.The tooth extraction wounds were treated by:platelet-rich fibrin +acellular dermal matrix(group A),platelet-rich fibrin(group B),acellular dermal matrix (group C) and without treatment (group D,the control) (n =9) respectively.The measurments of alveolar bone height and width showed that there were no significant differences among groups at different times(P ＞ 0.05).Bone histomorphometry showed that at the 2th and 4th week,the best result was found in group A(P＜0.01).While,at the 8th week,the result of group A was still better than that of other 3 ones (P ＜ 0.01),but group B and C showed no significant difference(P ＞ 0.05).The combination of PRF and ADM shows the most significant effect.
