中文摘要
目的 研究数字化导板应用于前牙美学区种植修复的精确度。方法 选择50例需接受上前牙种植修复的患者为研究对象,随机分为2组,每组25例,分别实施常规种植修复（对照组,45枚种植体）和数字化导板辅助种植修复（试验组,51枚种植体）,术后测量2组植入体术前虚拟设计位置与实际植入位置的颈部距离、根尖部距离、深度和角度偏差。在全瓷冠修复完成后1周（基线）、6个月和1年,观察2组患者术后种植体的临床修复疗效,采用红白美学评分[包括红美学分数（PES）和白美学分数（WES）]评价软组织及牙冠修复的美学效果。结果 50例患者的96颗种植体术后均取得了良好的骨结合。试验组种植体植入位置的各项偏差均小于对照组（P<0.05）;修复完成后1周、6个月和1年,试验组的PES及WES均高于对照组（P<0.05）。结论 数字化导板辅助种植修复技术可以提高种植体三维位置的准确性和前牙美学区的修复效果。
英文摘要
ObjectiveTo study the precision of digital guide plates applied to the implant surgery of anterior teeth.MethodsFifty patients scheduled to receive implant restoration treatment in anterior teeth were enrolled in this study and divided into two groups (n=25, each group): those who were given routine implant restoration treatment (control group, 45 implants) and those who received implant restoration treatment using a digital guide plate (test group, 51 implants). After implantation, planned and placed implants were superimposed using digital software, and deviations (corona, apex, depth, degree) were analyzed. Esthetic parameters were assessed at 1 week (baseline), 6 month, and 1 year post final restoration. Pink esthetic (PES) and white esthetic (WES) scores were respectively used to evaluate the soft tissue and restoration esthetic outcome.ResultsThe deviation parameters in the test group were significantly lower than those in the control group (P<0 .05). pes and wes values recorded for the control group at 1 week, 6 month, and 1 year post final restoration were significantly lower than those in the test group (P<0 .05).ConclusionThe digital guide plate can improve the accuracy of the three-dimensional position of implants in the maxillary esthetic zone. As such, this device may play an important role in obtaining the ideal aesthetic effects of maxillary anterior teeth.
