即刻种植与种植体早期加载的临床研究

目的探讨即刻种植与种植体早期加载的临床效果。方法患者37例，拔牙后即刻植入64枚种植体。36枚为Ⅰ期完成手术，其中无牙颌患者覆盖义齿的种植体17枚均即刻加载；14枚种植体于术后1～2个月早期加载，22枚种植体于3～4个月加载。28枚3～6个月后行Ⅱ期手术，常规修复。结果全部种植体稳定无松动，种植体周围无炎症。X线片未见明显骨吸收，即刻加载和即刻修复的病例与常规方法修复的种植体周围龈袋深度差异无统计学意义。结论即刻种植与种植后早期加载缩短了种植修复疗程，其疗效与常规方法修复无差异。

Clinical study of immediate placement and early loading of dental implants

Objective To evaluate the clinical results of immediate placement and early loading of dental implants. Methods Sixty-four dental implants were inserted into the edentulous section of 37 patients immediately after the teeth were extracted. 36 implants were inserted by one-stage operation procedure, of which 17 implants were loaded immediately in 3 edentulous jaws by temporary mandibular overdenture. Fixed crown restoration were completed on 14 implants in 1-2 months and on 22 implants in 3-4 months. The twostage operation for another 28 implants were performed after 3-6 months and then were restored by routine methods. Results All implants were inserted successfully and stable. There was no peri-implantitis and X- ray films indicated that no remarkable bone resorption occurred. There were no significant differences in the pod-implant depths of gingival pocket between early loading implants and routine restoration. Conclusions Dental immediate implant and early loading after implantation can shorten the treatment period of implantsupported prosthesis. The short-term clinical performance was not different from the routine method.
