摘　　要：目的探究三维虚拟牙科患者的建立对前牙美学修复效果的影响。方法选取30例需进行上前牙瓷贴面或全瓷冠修复的患者,分3组:组一建立三维虚拟牙科患者进行修复设计;组二结合二维面部照片设计;组三不参考面部信息,仅基于CAD/CAM形态数据库进行设计。制定前牙美学修复效果评价量表,由三位医师对术后美学效果进行评分比较。患者采用视觉模拟评分法(visual analogue scales,VAS)进行前牙美学修复效果满意度评价。结果(1)实现三维虚拟牙科患者的临床建模路径,完成整合面部美学要素的前牙修复效果评价量表的制定。(2)术后美学效果医师评价:组一、组二、组三总评分分别为(82.53±2.70)、(80.30±1.77)、(72.90±3.39)分,组三显著低于组一及组二(P<0.05);三组面部效果评分分别为(27.97±1.39)、(24.43±2.21)、(22.33±2.25)分,组一显著高于组二及组三(P<0.05)。三组患者满意度VAS评分分别为(8.70±0.71)、(7.30±0.67)、(6.60±0.84)分,组一显著高于组二及组三(P<0.05)。结论三维虚拟牙科患者的建立提高了前牙美学修复的可预测性;提升了修复体的整体协调度、平衡感与美观性;降低前牙区美学修复风险;具有临床应用价值。Objective To explore the effect of three-dimensional virtual dental patients on the aesthetic restoration of anterior teeth. Methods Thirty patients requiring porcelain veneers or all-ceramic crowns on anterior teeth were selected and divided into three groups: Group 1 established three-dimensional virtual dental patients for restoration design;Group 2 combined with two-dimensional facial photographs for design;Group 3 was designed based on CAD/CAM morphological database without personalized information of patients. Three clinicians were invited to rate postoperative aesthetic outcome on a dental aesthetic evaluation scale. Satisfaction with the aesthetic outcome of restoration was evaluated by patients with visual analogue scales(VAS) in all groups. Results The digital model of three-dimensional virtual dental patient was established successfully. A dental aesthetic evaluation scale incorporating aesthetic elements of the face was developed. The total score of three groups were(82.53±2.70),(80.30±1.77),(72.90±3.39) points;score of Group 3 was significantly lower than that of Group 1 and Group 2(P<0.05). The facial outcome score of three groups were(27.97±1.39),(24.43±2.21),(22.33±2.25) points;score of Group 1 was significantly higher than that of Group 2 and Group 3(P<0.05). The VAS score of three groups were(8.70±0.71),(7.30±0.67),(6.60±0.84) points;score of Group 1 was higher than that of Group 2 and Group 3(P<0.05). Conclusion The establishment of three-dimensional virtual dental patients improves the predictability of aesthetic restoration in anterior teeth and reduces the risk of aesthetic restorations in the anterior zone. The harmony, balance and aesthetics of restoration are improved, which has clinical application value.
