A novel method to treat and interpret distortion of denture impression trays has been proposed. When compared with the conventional method this approach, based on the general least squares principle, offers a significant advantage since the displacement for each individual point can be traced providing more profound insight into the character of the overall deformation itself. The method was applied to study dental impression trays manufactured of self-curing acrylic. The results indicate the existence of a large degree of individuality and non-uniform behaviour of a specific tray material. The method developed here can be applied to specimens of any arbitrary size and shape and it is not limited by the number of the reference points.
一种治疗和解释义齿印模托盘变形的新方法已被提出。与传统方法相比，这种基于广义最小二乘法原理的方法具有显著优势，因为可以追踪每个单独点的位移，从而更深入地了解整体变形本身的特征。该方法被应用于研究由自凝丙烯酸制成的牙科印模托盘。结果表明特定托盘材料存在很大程度的个体差异和非均匀行为。这里开发的方法可应用于任何任意大小和形状的标本，并且不受参考点数量的限制。
