摘要： 目的 分析数字化口腔模型采集技术在前牙区种植翻瓣术（FS）和非翻瓣术（FLS）中的应用效果。方法 选择2016年3月至2019年3月我院收治的前牙区牙缺失患者36例（56颗牙），依据手术方式分为FS组（18例，28颗牙）和FLS组（18例，28颗牙）。术前进行数字化口腔模型采集，获得锥形束CT图像，利用3D打印制作种植导板。评价指标包括术后种植精度、术后修复效果、患者主观舒适度。结果 FS组患者的种植体轴向和三维误差均明显低于FLS组，修复体与实际种植窝的吻合性评分明显优于FLS组，患者的主观舒适度优良率明显优于FLS组，差异均有统计学意义（P<0.05）。结论 在前牙区牙缺失的患者中合理使用数字化口腔模型采集辅助的种植操作，有利于提高模型采集与临床诊治的效率，模型的可操作性、可重复性较好。对于状态复杂的患者建议优先选择FS术式，有利于在前牙区种植中获得更高的精度，取得更好的种植体修复效果，改善患者的主观舒适度。

Abstract: Objective To analyze the effect of digital model acquisition technology on anterior teeth implantation in flap surgery (FS) and flapless surgery (FLS). Methods From March 2016 to March 2019,36 patients (56 teeth) with missing anterior teeth were enrolled and divided equally into FS and FLS groups (18 patients and 28 teeth in each group). Digital models were captured preoperatively,and cone beam CT imaging was obtained. The implant guides were made by 3D printing. The observation indexes included implant precision,repair effect,and subjective comfort. Results The axial and 3D errors were significantly lower in the FS group than in the FLS group (P<0.05). Additionally,the FS group had better anastomosis and subjective comfort scores than the FLS group (both P<0.05). Conclusion In patients with missing anterior teeth,the reasonable use of digital model acquisition technology is conducive to improve the efficiency of model collection and clinical diagnosis and treatment. In addition,the model has good operability and repeatability. For patients with complex conditions,it is advisable to choose FS first,which provides benefits of higher precision,better implant repair effect,and subjective comfort.
