Abstract

AIM: The aim of the present study is to evaluate the effect of CAD designing on the dimensions of the clasp arm. METHODOLOGY: A Kennedy Class III mod I cast was selected as the reference cast. Samples were divided into 2 groups, Group I with DMLS and Group II with Conventional lost wax technique. Three reference points were selected on the clasp arm and the vertical dimensions were measured in the digital design and compared it with the dimensions at the same points in the final framework. RESULTS: There was slight expansion in group 1 (p-value > 0.05) with mean of -0.035 and standard deviation 0.088. And there was decrease in dimensions in the clasp arm in group 2 (p-value < 0.05) with mean of 0.1741 and standard deviation 0.081. CONCLUSION: From the present study, it was concluded that the dimensions of the clasp arm of DMLS framework increased slightly, whereas the there was significant decrease in the clasp arm dimensions in the framework produced through conventional lost wax technique. Both the frameworks had clinically acceptable fit.

通过 DMLS 和传统失蜡技术制作的可摘局部义齿框架中扣臂的尺寸变化：体外研究

目的：本研究旨在评估 CAD 设计对扣臂尺寸的影响。方法：选择肯尼迪 III 类 I 型铸件作为参考铸件。样品分为两组，第一组采用 DMLS 技术，第二组采用传统失蜡技术。在扣臂上选择三个参考点，测量数字设计中的垂直尺寸，并与最终框架中相同点的尺寸进行比较。结果：第一组有轻微膨胀（p 值大于 0.05），平均值为-0.035，标准差为 0.088。而第 2 组的扣臂尺寸有所减小（p 值小于 0.05），平均值为 0.1741，标准差为 0.081。结论：本研究得出的结论是，DMLS 框架的扣臂尺寸略有增加，而通过传统失蜡技术制作的框架的扣臂尺寸显著减少。两种框架在临床上都具有可接受的密合度。
