Zimmer种植系统在后牙即刻种植的临床应用研究

CLINICAL APPLICATION OF IMMEDIATE IMPLANT PLACEMENT OF ZIMMER DENTAL IMPLANT SYSTEM IN THE MOLARREGIONS

目的观察Zimmer种植体在后牙区即刻种植的临床效果。方法选择14例19颗后牙区即刻种植病例,采用Zimmer种植系统,其中17颗同时行GBR技术,Ⅰ期术后4～6个月,Ⅱ期术后2周,上部结构采用钯金烤瓷冠修复。结果 19颗种植体骨结合良好,追踪12个月,种植体稳存。结论 Zimmer在后牙区采用即刻种植可以取得良好的骨结合。在后牙区即刻种植手术过程中,正确的软硬组织处理可以在缩短疗程的同时,良好的恢复了原缺失牙周围的骨组织缺损及周围牙龈组织形态。在后牙区即刻种植时,应选择恰当的适应症,避免盲目即刻种植。

Objective To observe the clinical effects of the immediate implant placement of Zimmer dental implant system in the molar regions. Methods 14 cases with a total of 19 molar teeth to be scheduled for immediate implant were selected to be treated with Zimmer dental implant system. 17 of the 19 molar teeth were simultaneously operated with GBR technique. The upper structure was repaired with Palladium PFM porcelain crown after the postoperative phase I of 4 ～ 6 months and postoperative phase II of 2 weeks. Results All the 19 dental implants were well combined and were stable in the following 12 months. Conclusion A good osseointegration is obtained in the molar teeth with Zimmer dental implant system. Correctly dealing with the soft and hard tissues in the process of immediate implant of molar teeth shortens the period of treatment,and repairs the bone tissue defects around the original lost teeth and the surrounding gingival tissue form. The immediate implant should be applied properly in the molar teeth.
