In vitro study on reliability of digital scanning in duplicating removable partial dentures casts
AUTHOR(S): Dr. Omar Mohammad Al tammas and Dr. Hussein Ali Al Essa
The main purpose of this study is to determine the dimensional accuracy of digital models as compared to that of study models and the reliability of digital scanning. The study aims to measure and compare distances between selected landmarks on study models and digital models and angles of cervical convergence of the abutment teeth.
Material and Methods: The study used partially edentulous study models of each of Kennedy’s class I and III classifications. All the models were scanned using scanner and digitized on the computer. The physical models and digitized models were scanned and measured using various parameters and study designs. Measurements were conducted directly on study models and computer models using Altair Hyper mesh network version 7.0. The differences between the two seta of measurement were statistically analyzed using a suitable method (t- test).
Results: The differences between measurement of distance on study models and digital models were found to be within the precision of 0,08 mm and 0,21 for the angle of cervical convergence of the abutment teeth. All these measurements were statistically slightly significant and well within the range of intra operator variations.
Conclusion: This study shows that dental cast can be scanned with the help of an accurate and sophisticated scanner and the scanned data can be transferred to the computer and used for the purpose of digital scanning.
