目的:探讨根尖周感染拔牙后即刻种植术的临床疗效。方法:随即选择根尖周感染患者38例,不可保留患牙42颗,抗感染治疗,拔除患牙,即刻非埋入式种植。回顾分析,随机选择既往病例资料,根尖周感染患者38例,不可保留患牙42颗,延期非埋入式种植。结果:两组近期并发症中松动、折断无差别,而术后肿胀、慢性牙龈炎存在显著差别,P<0.05。负荷1年的随访记录表明,X线垂直骨吸收、满意度调查无显著差别。结论:选择合适的材料,初期稳定性好,炎症期拔牙后即刻种植,是可取的治疗方法,疗效确切,疗程短、费用少、患者乐于接受。 Objective: To investigate the clinical effect of immediate peri-implant surgery after perianal infection. Methods: Thirty-eight cases of periapical infection were randomly selected. 42 cases of the affected teeth should not be reserved. Anti-infective treatment should be performed to remove the affected teeth and implant immediately. Retrospective analysis, the random selection of previous case information, periapical infection in 38 patients, can not retain 42 teeth, postponed non-buried planting. Results: There was no difference between the two groups in the recent complications, but there was a significant difference between postoperative swelling and chronic gingivitis (P <0.05). One-year follow-up records showed that there was no significant difference in vertical bone resorption and satisfaction survey. Conclusion: It is preferable to choose suitable materials with good initial stability and implantation immediately after tooth extraction in inflammatory stage. The curative effect is exact, the course of treatment is short, the cost is low, and the patients are willing to accept it.
