Achievement of an excellent contact, one that provides a natural look and feel, reproducing the natural tooth contact or sometimes improving it, can be achieved in many ways. Understanding the separate issues of tightness and anatomy is crucial to achieving the desired result. In most cases, use of a contoured sectional matrix and McKean-style ring is the surest way to achieve the desired result. Unusual circumstances, such as wide preparations and malpositioned teeth, call for innovative techniques, some of which are illustrated in this article.
实现良好的接触，即呈现自然的外观和感觉，再现天然牙齿的接触情况，有时还能加以改善，可通过多种方式达成。理解贴合度和解剖结构等不同问题对于实现预期效果至关重要。在大多数情况下，使用塑形分段成型片和麦基恩式环是实现预期效果的最可靠方法。特殊情况，如牙体预备宽大和牙齿位置异常，则需要创新技术，本文将举例说明其中一些技术。
