Several methods are currently available for providing a preview of the prosthodontic treatment, including computer simulations, 3D models, wax-ups, and mock-ups. The aim of this study is to compare the aesthetic aspects and assessment of conventional versus digital prefigurative methods.
The study included 5 patients and 3 observers, for each of whom a wax-up was made in both the conventional and digital techniques. The analog method, which implied a mock-up molding with a silicone matrix of the wax-up, was compared to a digital workflow, which consisted of a mock-up milling from a digital design. The patient's clinical mock-ups were recorded with digital photographs and assessed for nine different criteria by three observers.
The analysis has shown a balanced assessment of the aesthetic criteria without any significant difference between the analog and digital prefigurative methods.
Between the two wax-ups (conventional and digital), there were some variations in smile and dental criteria; however, the obtained data were very similar. When it comes to the smile criteria, the general average grades of the mock-ups conducted using the conventional method are slightly higher than the ones using the digital technique.
目前有几种方法可用于提供口腔修复治疗的预览，包括计算机模拟、3D模型、蜡型和模型。本研究的目的是比较传统预成方法与数字预成方法的美学方面和评估。
该研究包括5名患者和3名观察者，对他们每个人都采用传统技术和数字技术制作蜡型。将模拟方法（即使用蜡型的硅橡胶基质进行模型成型）与数字工作流程进行比较，数字工作流程包括根据数字设计进行模型铣削。用数码照片记录患者的临床模型，并由三名观察者根据九个不同标准进行评估。
分析表明，美学标准的评估较为平衡，模拟和数字预成方法之间没有显著差异。
在两种蜡型（传统蜡型和数字蜡型）之间，微笑和牙齿标准存在一些差异；然而，获得的数据非常相似。在微笑标准方面，使用传统方法制作的模型的总体平均分数略高于使用数字技术制作的模型。
