Abstract
Objective:The present study aimed to observe the influence of xeograft of mixture of autologous and artificial bone powder plus an absorptive membrane on the alveolar bone regeneration of odontectomized wisdom tooth sockets. Methods:24 mesial impacted third molar were selected to experimental or control group according to randomization prin-ciple. The extraction socket was grafted with mixture of autologous and artificial powder plus a membrane. Probing depth level (PDL), bone density (BD) and bone gain (BG) were evaluated by probing, X ray, and CBCT respectively at 6 months post-operation; t test was made between groups via SAS software. Results: Only one case in experimental group felt hot and cold stimulation pain and nine cases felt that pain in the control group;the PDL was (2.92±0.90) mm in experimental group and (3.00±1.35) mm in the control group respectively(P=0.8603);the BD was 129.42±7.81 in the experimental group and 121.82±9.44 in the control group respectively (P=0.0.0429); bone gain of experimental group was (4.07±0.91) mm, higher than (2.38±1.09) mm of the control, P<0.01. Conclusion:Graft of autologous bone and artificial bone powder mix-ture plus absorbable membrane in the same period of third molar extraction, can decrease the distal alveolar loss of second molar after impacted third molar extraction, enhance bone gain, and clinical attachment level, thus reduce the risk of caries and periodontal disease, and helps to develop long-term stability of adjacent molar's periodontal tissue.关键词
