This article presents a clinical technique for transferring Digital Smile Design (DSD) information and a digital wax-up to fabricate highly personalized ceramic laminate veneers. The hybrid workflow of digitally designed wax-up and conventional hand-crafted veneers is showcased in a female adult who sought to improve her smile due to maxillary anterior incisal wear. The ceramic veneers, layered by feldspathic porcelain, followed the contours and shade blueprint planned with the digital wax-up. The DSD improved the harmony of the facial-and-smile relationship, and the ceramic restorations fulfilled the patient's esthetic and functional demands. Guides based on the printed model with the digitally designed wax-up can provide a reference for pressed lithium disilicate veneers layered with feldspathic porcelain.
本文介绍了一种将数字化微笑设计(Digital Smile Design,DSD)信息和数字蜡型转移到制作高度个性化的陶瓷贴面的临床技术。数字化设计的蜡型与传统手工制作贴面的混合工作流程在一位因上颌前牙切端磨损而寻求改善笑容的成年女性中进行了展示。分层施长石瓷的陶瓷贴面遵循了数字蜡型规划的轮廓和色调蓝图。DSD 改善了面部和微笑关系的协调性,陶瓷修复体满足了患者的美观和功能需求。基于带有数字设计蜡型的打印模型制作的导板可作为施加大理石瓷的加压硅酸二锂贴面的参考。
