目的：评价数字化快速成型种植导板在上前牙区种植的临床应用效果。方法对2010年4月至2012年6月在河南大学第一附属医院口腔科就诊的6例上前牙缺失患者，拍摄螺旋CT及常规取超硬石膏模型，经过三维重建、模拟种植及数字化快速成型技术制作导板后，将该导板应用于手术中。术后再次拍摄螺旋CT并与术前的情况进行对比。结果6例患者均应用该导板完成手术，手术效果满意。患者术后反应轻微，植入后3～6个月均顺利完成冠部修复，美观效果良好。经过术前、术后CT结果对比，种植体颈部的偏移为（0.71±0.17）mm，根部的偏移为（0.85±0.19）mm。结论数字化快速成型种植导板应用于上前牙种植，具有明显的技术优势与广阔的应用前景。

Objective To evaluate the effect of the application of digital rapid process implant template in implant sur-gery of maxillary anterior teeth area. Methods Totally six patients with maxillary anterior teeth missing who need im-plant surgery were collected and the implant template was made by digital rapid process technology and was used in im-plant surgery. Then the deviations of the implant body were measured. Results The surgery process was satisfactory. Slight postoperative reaction was observed,and 3-6 months after implant crown repair was successfully completed. In CT image the deviation of the neck and apical of the implant body was(0.71±0.17)mm and(0.85±0.19)mm,respectively. Conclusion The digital rapid process implant template is a very effective method in implant surgery of maxillary anteri-or teeth area.
