【摘要】 目的:观察隧道开放式模板在牙种植手术中的作用。方法:对13例缺牙患者取模后灌制工作模型,雕蜡牙,恢复牙列的完整性,在蜡牙上制作开放式植入隧道;二次取模灌模型后,采用热压成型技术制作隧道开放式模板。手术时按隧道方向钻孔并植入种植体。结果:12例患者的工作模型及X线片显示,植入位置和方向与预定方向基本一致,并取得了较好的修复效果。结论:使用隧道开放式种植模板,能使术者较准确地把握牙种植体植入的位置与方向,制作简单,使用方便。更多还原

【Abstract】 PURPOSE: To observe the effect of orbital dental template with part-opening channels used in dental implant surgery. METHODS: Working casts were made for 13 cases with missing teeth after impressions were taken. The dentitions of the cases were then restored with wax teeth. Part-opening channels were made through the wax teeth. After that, impressions and working casts were made again to fabricate the template with part-opening channels by thermo-forming technique. During the implant surgery, the drilling of the bur and inserting of the implants were guided by the part-opening channels on the templates. RESULTS: The working cast and X-ray films of the 12 cases showed that all implants were placed in desirable location and accurate direction with satisfactory prostheses. CONCLUSION: The dental template with part-opening channels could help the operator to place the implants in desirable location and direction successfully. Its fabrication was simple, but it could offer us great convenience. Supported by Research Fund of Science and Technology Bureau of Shandong Province (Grant No.022130150).更多还原
