Abstract: Objective: To analyze the clinical application effect of tooth extraction site preservation technology in dental implantation. Methods: To choose between April 2017 and May 2017 in our hospital to see a doctor to 60 patients with tooth extraction and dental implants as the research object, using the random number table method divided into control group and experimental group, 30 cases in each group. The ref-erence group underwent routine treatment after tooth extraction, followed by dental implant implantation. In the experimental group, tooth extraction was followed by tooth extraction site preservation and dental implant implantation. Results: The planting success rate of the experimental group was 96.7% (29/30), and that of the control group was 66.7% (20/30). The score of aesthetic effect and satisfaction index of pa-tients in the experimental group was significantly higher than that of the control group, and the data of the two groups were significantly different(P<0.05). Conclusion: Oral planting restoration process of the tooth extraction sites preservation technology, can effectively reduce pressure after tooth extraction in patients with bone absorption, reduce loss of teeth and bone height, width, late to give oral implant prosthesis to create more good planting environment, can effectively improve oral planting the chances of success.
