Obtaining a firm anatomic contact has been a difficult criteria in placing Class II posterior composite restorations. Various techniques have been developed and a number of products marketed to accomplish this task, but none have combined the necessary qualifications of ease, simplicity, and effectiveness for consistent and predictable results. To address this challenge, two innovative devices--a precontoured (biplanar concave) sectional matrix band and a light--focusing tip-have been developed. Using a clinical case presentation, this article describes the application of these devices to obtain high quality proximal contacts, even in widely separated teeth. The learning objective of this article is to familiarize clinicians with this procedure. The technique is simple and universally applicable with a variety of posterior composite materials and placement methods.
在放置Ⅱ类后牙复合树脂修复体时，获得稳固的解剖接触一直是一项困难的标准。已经开发了各种技术，并销售了许多产品来完成这项任务，但没有一种技术能将简便性、简易性和有效性这些必要条件结合起来，以获得一致且可预测的结果。为应对这一挑战，已开发出两种创新装置——一种预成型（双平面凹面）分段成型片带和一个聚光尖端。本文通过一个临床病例展示，描述了这些装置在获得高质量邻面接触方面的应用，即使是在间隙较大的牙齿中。本文的学习目标是让临床医生熟悉这一操作程序。该技术简单，普遍适用于各种后牙复合树脂材料和放置方法。
