Abstract:
Objective:To study the feasibility of a new composite mineralized collagen membrane in alveolar ridge preservation.Methods:The third mandibular premolars on both sides were extracted from 12 dogs,the 24 alveolar sockets were randomly assigned into A,B and C groups(n =8).The distal alveolar sockets of group A was immediately implanted with the new composite mineralized collagen membrane and bone graft material,those of group B with bone graft material,group C was the blank control.The healing of sockets was evaluated by gross observation,morphological measurements,X-ray microscope and photographs of spiral CT.Results:The horizontal width of the alveolar process of group A was bigger than that of group B (P ＜ 0.05),that of group B was bigger than that of group C (P ＜ 0.05).The region of extraction interest in spiral CT value was higher in group A than that in group B and C (P ＜ 0.05).The extraction sockets were generated new bone and the degree of reconstruction measurements was higher in group A than that in group B and C (P ＜ 0.05).Conclusion:The new composite mineralized collagen membrane can induce the regeneration of new bone,and preserve the alveolar.
