Crowns and veneers provide distinct treatment strategies with different outcomes in terms of tissue conservation, periodontal distress and esthetic result. It is not always clear where a crown or veneer is indicated, but in the last two decades, adhesive technology, conservative approaches and esthetic demands have increased clinical indications for porcelain veneers in restorative dentistry. A combination of veneers and crowns may be required, especially in the anterior region. It may be desirable to reinforce some teeth and preserve tissue on others. Problems can arise with the esthetic integration of both types of restoration, owing to their inherent mechanical and optical properties. Several clinical and laboratory techniques can be applied for a successful combination. In this article the authors describe the procedures and difficulties in treating a case with such needs.
牙冠和贴面提供了不同的治疗策略，在组织保存、牙周不适和美学效果方面有不同的结果。牙冠或贴面的适用情况并不总是很明确，但在过去二十年里，粘结技术、保守方法和美学需求增加了瓷贴面在修复牙科中的临床应用指征。可能需要结合使用贴面和牙冠，尤其是在前牙区。可能需要加固一些牙齿并保留其他牙齿的组织。由于这两种修复体固有的机械和光学特性，在美学整合方面可能会出现问题。可以应用几种临床和实验室技术来实现成功的结合。在本文中，作者描述了处理此类需求病例的程序和困难。
