OBJECTIVE
To evaluate the clinical result of immediate implant.
METHODS
32 cases underwent immediate implant surgery for 59 implants simultaneously when the teeth or roots extracted. 55 implants were placed with bone grafts or bone substitutes. The second stage operation were performed in the sixth month and ceramic crown were fixed in the seventh to eighth month postoperatively, the follow up were mean 39 months.
RESULTS
One implant was lost. Bone resorption of alveolar crest was observed in 4 implants. Mean resorption was 2 mm.
CONCLUSIONS
The result of immediate implant is predictable, the advantages are avoiding the alveolar bone resorption after teeth extraction, implant could be placed in an ideal position; less operation trauma, good esthetics results.
目的
评估即刻种植的临床效果。
方法
32例患者在拔牙时同时对59颗种植体进行即刻种植手术。55颗种植体植入时使用了骨移植材料或骨替代物。术后6个月进行二期手术，7至8个月安装烤瓷冠，平均随访39个月。
结果
1颗种植体脱落。4颗种植体出现牙槽嵴骨吸收，平均吸收2毫米。
结论
即刻种植效果可预测，优点是避免拔牙后牙槽骨吸收，种植体可置于理想位置；手术创伤小，美学效果好。
