自体骨结合人工骨粉对前牙美学区骨量不足患者骨增量的影响

Impact of Autogenous Bone Combined with Artificial Bone Powder on Bone Augmentation in Patients with Bone Loss in Anterior Aesthetic Area

目的 探讨自体骨结合人工骨粉对前牙美学区骨量不足患者骨增量的影响。方法 90例前牙美学区骨量不足患者随机分为两组,观察组给予自体骨结合人工骨粉修复,对照组给予完全自体骨修复,比较两组的骨增量、美学评分、牙周指标以及并发症。结果 两组垂直向、水平向的骨增量比较,差异均无统计学意义(P>0.05)。治疗后,两组的PES、 GI、 SBI、 PLI评分均显著改善(P <0.05),但组间比较差异无统计学意义(P>0.05)。观察组的并发症发生率显著低于对照组(P <0.05)。结论 对于前牙美学区骨量不足患者,自体骨结合人工骨粉修复与完全自体骨修复的效果相当,但前者的并发症发生率更低。

Objective To explore the impact of autogenous bone combined with artificial bone powder on bone augmentation in patients with bone loss in anterior aesthetic area.Methods 90 patients with bone loss in anterior aesthetic area were randomly divided into two groups.The observation group received autogenous bone combined with artificial bone powder repair,while the control group received complete autologous bone repair.The bone augmentation,aesthetic score,periodontal indicators and complications were compared between the two groups.Results No significant difference was found in the vertical bone augmentation and horizontal bone augmentation between the two groups(P >0.05).After treatment,the PES,GI,SBI and PLI scores of the two groups improved significantly(P 0.05).The incidence of complications in the observation group was significantly lower than that in the control group(P <0.05).Conclusions For patients with bone loss in anterior aesthetic area,the effect of autogenous bone combined with artificial bone powder repair is equivalent to that of complete autologous bone repair,but the former has lower incidence of complications.
