牙周病患者拔牙后即刻种植与延期种植的临床研究

Immediate Implant vs. Delayed Implant in Periodontally Compromised Sites

目的:探讨牙周病患者拔牙后即刻种植与延期种植的临床效果。方法 :68例慢性中、重度牙周病患者,在牙周治疗后,随机选择34例拔除患牙后即刻种植41枚种植体;另外34例患者拔牙后3个月延期种植45枚种植体。术后随访2年,评价种植体的存留率、牙周探诊深度、美学评分、种植体颈部骨吸收率。结果:种植体脱落情况,即刻种植组3枚,延期种植组2枚,存留率分别为92.68%和95.56%;2年随访期内,仅第3个月的美学评分差异有统计学意义。结论:术前控制牙周炎,术中彻底刮除拔牙窝中的感染组织,配合使用抗生素,牙周病患者即刻种植可取得与延期种植类似效果。

Objective： To compare the clinical outcomes of immediate implant and delayed implant after tooth extraction in periodontits patients. Methods： 68 cases of moderate and severe periodontits patients were randomly divided into two groups： immediately implant group （34 cases, 41 implants）, delayed implant group （34 cases, 45 implants installed three months later）. Clinical examination of implants was performed regarding the survival rate, the stability, peri-implant bone absorption, peri-implantar sulcus depth, and pink esthetic score （PES） of peri-implant soft tissues. Result： All patients completed the follow-up of 2 years. 3 cases of screw loosening and lost occurred in immediate group, and 2 cases occurred in delayed group, the success rate was 92.68%and 95.56%respectively. The only difference in statistically significant was PES evaluation at 3 months after restoration. Conclusion：In conditions of the periodontal disease was controlled, immedi-ately implantion can achieved similar results with delayed implantion.
