摘要
目的探讨牙周病患者前牙拔除后种植体不同植入时机对手术结局、美学效果及稳定性的影响,为临床对该类患者修复时机的选择提供借鉴。方法对2018年1月至2019年7月在南阳市中心医院接受种植体植入修复前牙的71例(86颗种植体)牙周病患者临床资料进行回顾性分析,根据种植体植入时机不同将其分为即刻种植组(拔牙后6 h内)、早期种植组(拔牙后6 h后7 d内)和延期种植组(拔牙后7 d后)3组。修复后随访3年,比较3组种植体种植成功率、牙周探诊深度、红色美学(PES)评分、骨吸收量等参数。结果本研究71例研究对象共种植86颗种植体,其中即刻种植组25例(29颗),早期种植组22例(27颗),延期种植组24例(30颗),种植成功79颗,总种植成功率为91.86%;其中即刻种植组种植成功率为93.10%(27/29),早期种植组为92.59%(25/27),延期种植组为90.00%(27/30),组间比较差异无统计学意义(χ^(2)=1.937,P=0.185)。3组种植体植入时、术后3个月、6个月、12个月、24个月、36个月牙周探诊深度比较差异无统计学意义(P>0.05);3组间种植体植入时PES评分、骨吸收量,组间对应比较差异均无统计学意义(均P>0.05),术后3个月、6个月、12个月、24个月、36个月时即刻种植组PES评分均高于早期种植组和延期种植组(P<0.05);术后3个月、6个月、12个月时即刻种植组骨吸收量低于早期种植组和延期种植组(P<0.05),术后24个月、36个月时3组间骨吸收量比较,差异均无统计学意义(均P>0.05)。结论种植体即刻植入与择期植入对种植成功率与牙周探诊深度影响不大,但即刻植入可减少手术次数,减轻组织损伤程度,降低早期骨吸收量,提升植入体长期稳定性和软组织美学效果。
【Objective】To investigate the effects of different implant timings on surgical outcomes,aesthetic effects and stability after anterior tooth extraction in patients with periodontal disease,in order to provide reference for the selection of restoration timing for these patients.【Methods】The clinical data of 71 patients with periodontal disease(86 implants)who received implants to repair anterior teeth in our hospital from January 2018 to July 2019 were retrospectively analyzed.They were divided into three groups:immediate implantation group(within 6 hours after tooth extraction),early implantation group(within 6 hours and 7 days after tooth extraction)and delayed implantation group(7 days after tooth extraction).The three groups were followed up for 3 years,and the parameters such as implant placement success rate,periodontal probing depth,PES aesthetic score,and bone resorption were compared among the three groups.【Results】A total of 86 implants were implanted in 71 subjects in this study,including 25 cases(29 implants)in the immediate implantation group,22 cases(27 implants)in the early implantation group,and 24 cases(30 implants)in the delayed implantation group.Seventy-nine implants were successfully implanted.The implantation success rate was 91.86%;the immediate implantation group was 93.10%(27/29),the early implantation group was 92.59%(25/27),and the delayed implantation group was 90.00%(27/30).There was no statistical difference between the groups(χ^(2)=1.937,P=0.185).There was no significant difference in periodontal probing depth between the three groups at the time of implant placement,3 months,6 months,12 months,24 months,and 36 months after surgery(P>0.05).There was no significant difference in the PES aesthetic score and bone resorption between the groups at the time of implantation(all P>0.05).The PES aesthetic scores of the immediate implantation group were higher than those of the early implantation group and the delayed implantation group,and the difference was statistically signifi
