Interim veneers present an esthetic and functional challenge for restorative dentists. Moreover, inadequate fit or trauma to the soft tissue during their fabrication or subsequently may affect soft-tissue health and stability and lead to bleeding that will compromise the adhesive cementation of the definitive ceramic veneers. This article describes a technique for the atraumatic fabrication of interim veneers with a custom, rigid, clear matrix designed for multipurpose use during the patient's restorative care. Based on a diagnostic waxing, the clear matrix is made and first used for the fabrication of the trial restorations and as a tooth-preparation guide. Subsequently, it is used for the atraumatic fabrication of interim veneers with a photopolymerizing direct restorative material.
临时贴面给修复牙医带来了美观和功能上的挑战。此外，在制作或随后的过程中，如果临时贴面与软组织的贴合不充分或对软组织造成创伤，可能会影响软组织的健康和稳定性，并导致出血，从而影响最终陶瓷贴面的黏结。本文介绍了一种使用定制、刚性、透明模板进行微创制作临时贴面的技术，该模板设计用于患者修复治疗过程中的多种用途。基于诊断性蜡型，制作透明模板，首先用于制作试修复体和牙体预备指南。随后，用光固化直接修复材料进行微创制作临时贴面。
