The allure of multiple porcelain veneers resides in the conservative preparation and the potential for excellent esthetics. To uphold the pennant of adhesive technology on which the procedure is founded, the fastidious guidelines of direct adhesive techniques should be carried over to porcelain veneers. Delivery of porcelain veneers is compromised in the absence of rubber dam isolation. Traditional rubber dam application is cumbersome and impractical, however, during placement of multiple veneers, with their priority of gingival margin access. This article introduces a rubber dam-retaining appliance that improves access and isolation during the restoration of anterior teeth with multiple porcelain veneers.
多颗瓷贴面的魅力在于其保守的牙体预备方式以及实现出色美学效果的潜力。为秉持该修复程序所基于的粘接技术理念,直接粘接技术的严格指导原则应适用于瓷贴面。在未使用橡皮障隔离的情况下,瓷贴面的就位会受到影响。然而,传统橡皮障的应用在多颗贴面修复时很麻烦且不实用,因为此时重点在于龈缘的操作空间。本文介绍一种橡皮障固定装置,它能在多颗瓷贴面修复上前牙的过程中改善操作空间并增强隔离效果。
