The best way to adjust proximal contacts of newly fabricated indirect restorations has been a long-standing unresolved issue in dentistry. Excessively tight contacts cause incomplete seating of indirect restorations and intrusion of adjacent teeth, which leads to patient discomfort, hypersensitivity, and recurrent dental caries at the crown margins. When seating indirect restorations, interproximal relief should be restored as it exists in natural dentition. This article presents an innovative method of crown seating using diamond strips. This simple, consistent, method makes it easier for clinicians to provide comfortable and long-lasting restorations with minimal time and effort. Laboratory technicians utilize diamond strips to provide properly fitting indirect restorations that require minimal adjustment upon clinical delivery. Diamond strips also allow for accurate determination of heavier proximal contacts, allowing dentists to adjust the proximal contact properly in the patients' mouths. Clinically, restoring natural proximal contacts is a critical factor to the success of indirect restorations. Using this method standardizes proper proximal contact adjustments of laboratory-fabricated indirect restorations between dental labs and dental offices. The method also helps to limit or eliminate the lingering proximal contact issue between clinicians and laboratory technicians.
调整新制作的间接修复体的邻面接触关系的最佳方法，长期以来一直是牙科领域未解决的问题。过紧的接触会导致间接修复体就位不全以及邻牙侵入，进而导致患者不适、过敏以及牙冠边缘复发性龋齿。在间接修复体就位时，应恢复天然牙列中存在的邻面间隙。本文介绍了一种使用金刚砂条进行牙冠就位的创新方法。这种简单、一致的方法使临床医生能够以最少的时间和精力提供舒适且持久的修复体。实验室技术人员使用金刚砂条来制作贴合良好的间接修复体，这些修复体在临床交付时只需进行最少的调整。金刚砂条还能准确确定较紧的邻面接触，使牙医能够在患者口腔中正确调整邻面接触。临床上，恢复天然邻面接触是间接修复成功的关键因素。使用这种方法可使牙科实验室和牙科诊所之间实验室制作的间接修复体的邻面接触调整标准化。该方法还有助于限制或消除临床医生与实验室技术人员之间长期存在的邻面接触问题。
