摘　　要：目的:观察钛合金种植体与纯钛种植体修复牙列缺损的力学性能及美学效果。方法:回顾性分析2020年1月-2022年9月笔者医院收治的160例牙列缺损患者的临床资料,按种植体不同修复方式分为观察组79例(108颗牙,采用钛合金种植体)和对照组81例(112颗牙,采用纯钛种植体)。比较两组的种植有效率、咀嚼效率、牙齿总咬合力、牙周健康指数、并发症发生率及美学评分差异。结果:两组种植总有效率比较,差异无统计学意义(P>0.05),但观察组显效率显著高于对照组(P<0.05);两组咀嚼效率治疗后均显著升高,且观察组咀嚼效率显著高于对照组(P<0.05);两组牙齿总咬合力随时间延长逐渐升高,且观察组各时间段内总咬合力显著高于对照组(P<0.05);两组菌斑指数、牙龈指数及龈沟出血指数均较术前降低,且观察组显著低于对照组(P<0.05);观察组种植体周围炎发生率显著低于对照组(P<0.05);观察组红白美学指数评分显著高于对照组(P<0.05)。结论:相比于纯钛种植体,钛合金种植体用于修复牙列缺损患者具有更强力学性能,可改善患者咀嚼和咬合能力,降低种植体周围炎的发生率,提高美学效果。Objective To observe the mechanical properties and aesthetics of titanium alloy implant and pure titanium implant in the restoration of dentition defects.Methods The clinical data of patients with dentition defects admitted to the hospital from January 2020 to September 2022 were retrospectively analyzed.According to different restoration methods of titanium alloy implant and pure titanium implant,the patients were divided into 79 cases(108 teeth)in observation group and 81 cases(112 teeth)in control group.The effective rate of implantation,masticatory efficiency,total bite force of teeth,periodontal health indexes,incidence rates of complications and aesthetics scores were compared between the two groups.Results There was no significant difference in the total effective rate of implantation between the two groups(P>0.05),but the markedly effective rate in observation group was significantly higher than that in control group(P<0.05).After treatment,the masticatory efficiency in the two groups was significantly increased(P<0.05),and the masticatory efficiency in observation group was significantly higher compared with that in control group(P<0.05).The total bite force of teeth in the two groups was gradually increased with time,and the total bite force in observation group at each time point was significantly higher than that in control group(P<0.05).The plaque index,gingival index,and sulcus bleeding index were reduced in the two groups compared with those before surgery,and the above indexes in observation group were significantly lower compared with those in control group(P<0.05).The incidence rate of peri-implantitis was significantly lower in observation group than that in control group(P<0.05).The pink aesthetic score and white aesthetic score were significantly higher in observation group compared to control group(P<0.05).Conclusion Compared with pure titanium implant,titanium alloy implant for patients with dentition defects has stronger mechanical properties,and can better improve the masticatory ability
