摘　　要：目的:通过对牙周病患者前牙的即刻种植临床研究,探讨牙周病患者前牙即刻种植的成功及风险因素。方法:对186名患者进行拔牙后即刻种植。所有患者都有轻度至中度的牙周病且均要求即刻种植治疗。种植术前患者均进行了牙周的基础治疗。最长临床跟踪随访5年。通过临床和放射的角度评估即刻种植的治疗效果。结果:自2007-2012年,186名牙周病患者超过500枚CDIC或replace种植体即刻植入拔牙窝,种植体存留率达到95.1%。接近80%的种植体松动发生在种植术后的六个月以内。结论:牙周病患者前牙的即刻种植较延期种植风险更大。上颌前牙即刻种植风险高于下颌。感染是失败的主要原因。根据患者的全身和局部条件合理选择手术时机和手术方式能有效控制失败风险。Objective：The purpose of this clinical study on periodontal patients with anterior immediate im-plant was to discuss the survival and risk factors, which affect anterior teeth immediate implant of peri-odontitis patient. Methods： In this study 186 patients were be operated with anterior teeth immediate implant. All the patient had moderate chronic periodontitis and required immediate implant therapy. Before the operation of implant, the patients received the basic periodontal therapy. The longest clinical followed-up were for 5 years. Clinical results of treatment were evaluated from clinical and radiographic standpoint. Results： More than 500 dental implants of 186 patients were placed in the sockets that the anterior teeth were extracted immediately from 2007 to 2012. The survival rate of immediate implant in periodontitis patient was 95.1% during 5 years. Nearly 80% of implant loosing happened during the first 6 months after the operation of implant. Conclusion： Anterior teeth immediate implant of peri-odontitis patient had higher risk than delay implant of periodontitis patient. Immediate implant in max-illa had higher risk than immediate implant in mandible. Inflammation was the primary risk that caused the implant loosing. According to the systemic and local conditions of the patients, the appropriate choice of operation and operation mode can effectively control failure risk.
