Articulating paper mark size is now understood to be non-descriptive of occlusal loads; in fact, many different sized marks can represent the same load, and equal sized marks do not represent similar loads. With a reported reliability between mark size and applied occlusal load of only 21%, choosing the paper marks to occlusally adjust, based upon their relative size and operator-subjective assessment of those various sizes, is tantamount to clinical guessing. Computerized occlusal analysis completely removes the operator subjectivity from the clinical decision-making process when attempting to isolate problem occlusal contacts. When an operator properly uses this technology, mark size, mark color-depth, donut-shaped halo contacts, as well as other color and mark appearance characteristics, are ignored as force indicators and used only as contact locators. Operator-subjective paper mark misperceptions are replaced with accurate knowledge of the true and measured contact order, contact applied load, contact quality, and proper contact isolation where problematic. This results in better overall force application to any installed implant prostheses during occlusal function, thereby enhancing its chance for an undamaged clinical service lifespan.
目前已认识到,咬合纸印记大小并不能描述咬合负荷;实际上,许多不同大小的印记可能代表相同的负荷,而相同大小的印记并不代表相似的负荷。据报道,印记大小与施加的咬合负荷之间的可靠性仅为21%,基于印记的相对大小以及操作者对这些不同大小的主观评估来选择用于咬合调整的纸印记,无异于临床猜测。在试图分离问题咬合接触时,计算机化咬合分析完全消除了临床决策过程中的操作者主观性。当操作者正确使用这项技术时,印记大小、印记颜色深度、甜甜圈状光晕接触以及其他颜色和印记外观特征都被视为力的指标而被忽略,仅用作接触定位器。操作者对纸印记的主观误解被对真实和测量的接触顺序、接触施加的负荷、接触质量以及有问题时的适当接触隔离的准确认识所取代。这导致在咬合功能期间对任何已安装的种植体假体有更好的整体力应用,从而增加其临床使用寿命不受损害的机会。
