目的观察即刻种植修复缺失牙后软硬组织的临床变化情况.方法 10例患者的种植体20枚(直径为4.1或4.8 mm,长度10或12 mm),其中10枚为即刻种植,10枚为常规种植,在即刻植入的同时进行引导骨再生(guided bone regeneration,GBR)的骨增量手术.完成义齿修复后随访观察1年,通过X线片分别测量即刻种植和常规种植的硬组织变化量,进行对比分析.同时记录各组种植体的牙周探诊深度和龈乳头指数,分析即刻种植对牙周软组织有无影响.结果 1年后10例患者的种植体20枚均存留,患者主观全部满意.种植体周软硬组织无病理性异常.1年后硬组织平均吸收值常规种植组(1.76±0.21) mm,即刻种植组(1.80±0.15) mm,两者比较差异无统计学意义(P＞0.05).对比1年后两组牙周探诊深度:即刻种植组(2.31 ±0.84)mm,常规种植组(2.27±0.84) mm,两组间差异无统计学意义(P＞0.05).两组龈乳头指数的频数分布比较,差异无统计学意义(P＞0.05).结论即刻种植的近期种植体周软硬组织变化达到临床治疗要求.

Objective To observe the change of hard tissue in dental immediate implantation.Methods Twenty implants were implanted in 10 patients including 10 implants of immediate implantation and 10 regular implantation.They were followed up for one year after functional loading.Hard and soft tissue changes were evaluated by measuring the mesial and distal bone lever on X-ray.Pocket probing depth and papilla index were assessed during 1 year follow up period.Results After one year of functional loading,the implant retention rate was 100％,the patient subjective satisfaction rate was 100％.Hard and soft tissues around implant showed no pathological abnormalities.The average absorption of hard tissue after 1 year in conventional group was (1.76 ±0.21) mm,and (1.80 ±0.15) mm in immediate implant group,which showed no statistically significant difference between the two groups.The pocket probing depth in immediate implantation group was (2.31 ± 0.84) mm and (2.27 ± 0.84)mm in conventional group (P ＞0.05).The frequency distributions of the scores of papilla index of both groups were not significantly different between the two groups.Conclusions The hard and soft tissue changes in immediate dental implantation were within the normal ranges.
