To investigate the feasibility of immediate implantation after extraction of anterior teeth in patients with periodontal disease and its clinical effect within 2 years.
Thirty patients (36 implants) who underwent anterior dental implant treatment for periodontal disease from 2016 to 2018 were randomly divided into immediate implantation group (17 implants) and delayed implantation group (19 implants). The patients were followed up for 2 years, the clinical parameters such as periodontal probing depth, pink esthetic score（PES）and implant neck bone resorption volume of implant neck were obtained. The data was statistically analyzed with SPSS 21.0 software package.
During the 2-year follow-up period, no implant loss, and there was no significant difference in the depth of peri-implant probing between the two groups at each time point(P＞0.05). There was no significant difference in the volume of bone resorption at implant neck between the two groups(P>0.05). At 6, 12 and 24 months after completion of superstructure repair, there was no significant difference in pink esthetic score（PES）between the two groups (P＞0.05), but there was significant difference in pink esthetic score（PES) at the third month after restoration (P＜0.05). The immediate implantation group obtained more satisfactory soft tissue morphology around the implants.
Under appropriate treatment conditions, there is no significant difference in implant success rate between immediate implantation and delayed implantation of anterior teeth in patients with periodontal disease. At the same time, it reduces the number of operations and shortens the course of treatment. In terms of soft tissue aesthetics, immediate implantation is slightly better than delayed implantation in the early stage after restoration, and can maintain a good soft tissue aesthetic effect.
探讨牙周病患者前牙拔除后即刻种植的可行性及其2年内的临床效果。
选取2016年至2018年因牙周病接受前牙种植治疗的30例患者（36枚种植体），随机分为即刻种植组（17枚种植体）和延期种植组（19枚种植体）。对患者进行2年随访，获取牙周探诊深度、粉色美学评分（PES）及种植体颈部骨吸收量等临床参数。采用SPSS 21.0软件包对数据进行统计学分析。
在2年随访期内，无种植体脱落，两组在各时间点的种植体周围探诊深度差异无统计学意义（P＞0.05）。两组种植体颈部骨吸收量差异无统计学意义（P>0.05）。在完成上部结构修复后6、12和24个月，两组的粉色美学评分（PES）差异无统计学意义（P＞0.05），但在修复后第3个月粉色美学评分（PES）差异有统计学意义（P＜0.05）。即刻种植组种植体周围软组织形态更满意。
在适当的治疗条件下，牙周病患者前牙即刻种植与延期种植的种植成功率差异无统计学意义。同时，减少了手术次数，缩短了疗程。在软组织美学方面，即刻种植在修复后早期略优于延期种植，且能维持良好的软组织美学效果。
