Abstract: 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, immediately implantion can achieved similar results with delayed implantion.

Key words: immediately implant, delayed implant, periodontal disease, bone loss

摘要： 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。
