摘　　要：目的:探讨即刻种植和延期种植在单颗牙种植中的应用价值。方法:选择2013年3月-2018年3月于笔者医院就诊的需行种植牙治疗的500例患者为研究对象,患者均为单颗牙种植修复,其中即刻种植患者250例,延期种植患者250例。即刻种植组在拔牙即刻行种植术,延期种植术在拔牙后6个月行种植术,术后均随访12个月。回顾性分析两组患者术后种植体成功率、PD、改良菌斑指数(mPL1)、改良龈沟出血指数(mBI)、红色美学(PES)评分、种植体边缘骨吸收量及不良反应发生率。结果:两组患者种植术后3、6、9、12个月的种植体成功率无统计学差异(P>0.05);两组患者种植术后12个月的PD、mPL1、mBI水平无统计学差异(P>0.05);即刻种植组术后3个月、6个月PES评分高于延期种植组(P<0.05);即刻种植组术后3个月、6个月种植体边缘骨吸收量小于延期种植组(P<0.05);两组患者种植术后不良反应发生率无统计学差异(P>0.05)。结论:即刻种植与延期种植在单颗牙种植患者中成功率、PD无明显差异,而即刻种植短期内边缘骨吸收更小,美观性更好。Objective To study application value of immediate implantation and delayed implantation in single tooth implantation.Methods 500 patients who were treated in the hospital and needed tooth implantation during the period from March 2013 to March 2018 were enrolled in the study.All patients underwent single tooth implantation repair,including 250 cases undergoing immediate implantation and 250 cases undergoing delayed implantation.The immediate implantation group was given implantation immediately after tooth extraction,while delayed implantation group was given implantation at 6 months after tooth extraction.All patients were followed up for 12 months.The success rate of postoperative implant, PD, modified plaque index (mPL1), modification sulcus bleeding index (mBI), pink esthetic score (PES) , volume of implantmarginal bone loss, and incidence of adverse reactions in both groups were statistically analyzed. Results There was nosignificant difference in success rate of implant between the two groups at 3 months, 6 months, 9 months, and 12 months afterimplantation (P >0.05). There was no significant difference in PD, mPL1 or mBI level between the two groups at 12 monthsafter implantation (P >0.05). At 3 months and 6 months after surgery, PES scores of immediate implantation group were higherthan those of delayed implantation group (P <0.05), while volume of implant marginal bone loss was less than that of delayedimplantation group (P <0.05). There was no significant difference in incidence of adverse reactions between the two groupsafter implantation (P >0.05). Conclusion There is no significant difference in the success rate of single tooth implantation andPD between immediate implantation and delayed implantation. The marginal bone loss of the former is less in the short term,and aesthetic property is better.
