Clinical effect analysis of guided bone tissue regeneration technique in implant repair of tooth losswith bone defect after oral and maxillofacial trauma

Objective To analyze the practical effect of guided bone tissue regeneration technique in implant repair of tooth loss with bone defect after oral and maxillofacial trauma.Methods A total of 80 cases of tooth loss with bone defect after oral and maxillofacial trauma were divided into group A and group B according to random numerical table,with 40 cases in each group.Group A was treated with second-stage maxillary anterior teeth implant repair,and group B was treated with guided bone tissue regeneration technique.The osteogenesis effect,aesthetic effect and implant restoration effect of the two groups were compared.Results After treatment,the pink esthetic score(PES)and white esthetic score(WES)of group B were(10.48±1.93)and(8.82±1.24)points,which were all higher than(9.03±1.07)and(7.14±1.10)points of group A,and the difference was statistically significant(P<0.05).After treatment,the alveolar bone thickness and osteogenesis thickness of group B were(6.90±0.72)and(2.46±0.51)mm,which were all higher than(5.45±0.91)and(1.17±0.36)mm of group A,and the difference was statistically significant(P<0.05).There were 35 cases of successful implant restorations in group A,with a success rate of 87.50%;40 cases of successful implant restorations in group B,with a success rate of 100.00%;the success rate of implant restoration in group B was higher than that in group A,and the difference was statistically significant(χ2=5.33,P<0.05).Conclusion Guided bone tissue regeneration technique has a significant application effect in the implant restoration of tooth loss with bone defect after oral and maxillofacial trauma,which can effectively accelerate the bone formation rate of implant and improve the success rate of implant restoration,and is beneficial to the improvement of oral and maxillofacial aesthetics.
