Direct composite resin restorations have been recognized for their valuable clinical service and respect of intact hard tissue. The cost-effectiveness and inherent minimally invasive approach of resin-based materials means that they are also gaining popularity for use in computer-aided design/computer-aided manufacture (CAD/CAM) procedures. Several cases from the student clinics at the Herman Ostrow School of Dentistry of USC are presented that could have been resolved either with direct composite resin restorations or with indirect porcelain veneers. A novel semi-indirect CAD/CAM approach, characterized by its absolute noninvasiveness and simplicity, was chosen instead. The bilaminar restoration consists of a customized histoanatomical CAD/CAM dentin base (incisoproximal cutback), and a generic enamel skin. The patients can be treated either in one clinical session (semi-directly) or in two clinical sessions (semi-indirectly). The purpose of this article is to present another tool from the anterior restorative armamentarium to bridge the gap between direct and indirect techniques.
直接复合树脂修复因其宝贵的临床服务和对完整硬组织的保护而得到认可。树脂基材料的成本效益和固有的微创方法意味着它们在计算机辅助设计/计算机辅助制造（CAD/CAM）程序中的应用也越来越普遍。本文展示了南加州大学赫尔曼·奥斯特罗牙科学院学生诊所的几个病例，这些病例既可以用直接复合树脂修复，也可以用间接瓷贴面解决。相反，我们选择了一种新颖的半间接CAD/CAM方法，其特点是绝对无创且操作简单。双层修复体由定制的组织解剖学CAD/CAM牙本质基底（切端邻面磨除）和通用的釉质表层组成。患者既可以在一个临床疗程中接受治疗（半直接法），也可以在两个临床疗程中接受治疗（半间接法）。本文的目的是介绍前牙修复手段中的另一种工具，以弥合直接和间接技术之间的差距。
