摘要/Abstract

摘要： 目的评价自主研发CAD-CAM种植导板制作系统在无牙颌种植修复中的临床应用。方法选择5例单颌无牙颌患者。锥形束CT扫描采集数据，导入自主研发种植导板软件进行导板的数字化设计，快速成型机制作种植导板。在导板引导下进行无牙颌种植手术，植入ITI种植体。3个月后复查，行种植义齿修复。术后定期随访。结果为5例患者制作完成丙烯酸树脂CAD-CAM种植导板，在导板引导下采用不翻瓣术式共植入38枚ITI种植体，初期稳定性良好，术后反应小。术后3个月骨结合良好，仅1枚种植体脱落。5例患者均采用固定式种植修复，术后6个月及1年的随访显示，修复体功能和美观良好。结论该自主研发的CAD-CAM种植导板制作系统应用于无牙颌种植手术，能实现术前精确设计和术中精确控制种植体位置，减少了手术创伤和术后并发症，取得良好的种植修复效果。

Abstract: Objective To evaluate the clinical application of a self-developed CAD-CAM implant guide template system used in implant restorations for edentulous patients. Methods Five patients with single edentulous jaw were selected. Data were acquired by cone-beam CT scan and imported into the self-developed software to design the digital implant guide templates. Physical guide templates were then rapid-prototyped. ITI implants were implanted guided by the template. After three months, definite prostheses were finished. Postoperative follow-ups were made periodically. Results Five acrylic resin CAD-CAM implant guide templates were fabricated. In the guidance of templates, flapless surgeries were made to place 38 ITI implants with good initial stabilities and small postoperative reactions. After three months, good osseointegrations were generated except one implant off. Fixed implant restorations were made for five patients. Six months and one year follow-ups showed good functional and aesthetic restorations. Conclusion The self-developed CAD-CAM implant guide template system can be applied in the edentulous implant surgery to achieve precise preoperative design and intra-operative accurate control of implant position, which can reduce surgical trauma and postoperative complications, and good effect of edentulous implant restoration can be acquired.
