即刻种植义齿的临床研究

目的 评估即刻种植义齿的临床技术特点及近期临床效果。方法 32例患者共59个牙位在拔牙的同时植入了种植体，55个牙位同时植骨。平均6个月后行Ⅱ期手术，暴露种植体，修复牙冠。修复后追踪时间平均39个月。结果 1颗种植体在愈合期内脱落，其余病例在修复后至最后1次复查，临床效果良好。结论 即刻种植的临床方法可行，3年成功率与传统种植方法相同，其具有避免骨吸收，手术创伤小，种植体位置与轴向好，修复美学效果好等优点。

Clinical study of immediate implant

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.
