Abstract

Abstract: Objective: To evaluate the application of Onlay bone grafting technique in dental aesthetic area of anterior teeth. Methods: To select 82 cases of patients undergoing dental implants repair surgery, according to the preoperative evaluation, the patients were given the Onlay bone grafting techniques and dental implants repair surgery. It was observed that the changes of alveolar ridge and dental aesthetic indexes during the period of Onlay bone grafting, and the survival rate of dental implants was recorded. Results: It was found that the horizontal bone mass of alveolar ridge(7.84±0.42)mm and the vertical bone mass of alveolar ridge(11.65±0.85)mm at the end of 3 months after Onlay bone grafting, and the horizontal bone mass of alveolar ridge(7.15±0.60)mm and the vertical bone mass of alveolar ridge(10.86±0.63)mm at the end of 6 months after Onlay bone grafting were significantly higher than that of pre-grafted bone, P=0.035、0.039、0.035、0.040, The PES(7.48±1.36) points,WES (7.56±1.09) points at the end of 3 months after dental implants surgery, and the PES(7.78±1.42) points,WES(7.82±1.51) points at the end of 6 months after dental implants surgery, were significantly higher than those before operation, P=0.040、0.043、0.038、0.032. After Onlay bone grafting, the bone tissue was beautiful and plump, the wound was well healed, there was no bone necrosis, and the implant survival rate was high. Conclusion: The application of Onlay bone grafting technique in the implantation and repair of the aesthetic area of anterior teeth can significantly improve the problem of insufficient bone quantity in the planting area. The bone healing is good and the implant survival rate is high, so it is worthy to be popularized.

Key words: Onlay bone grafting technique, dental aesthetic area of anterior teeth, dental implants, dental bone mass
