Abstract

Aim: The aim of this in vitro study is to compare three different techniques of scanning post space at different depths.
Background: The important factor for success of treatment depends on endodontic treatment as well as by restoring it with prosthodontic treatment. The post is mainly used to retain and hold the core so that crown prosthesis can be given.
Materials and Methods: Fifteen freshly extracted single rooted teeth were selected and endodontically treated. Post space were created. Total Sample size taken was fifteen. There were three groups each with sample size of five. First group consist of Post space scanned with Omnicam intra oral scanner. Second group consist of Post space pattern scanned with InEos X5 Extraoral scanner. Third group consist of Post space impression made with Addition silicone, Poured and scanned with InEos X5 Extraoral scanner. Scanning files of all the three techniques were then converted to standard STL files. Diameter was measured at three different depths i.e., 3mm, 6mm & 9mm. Also, height & diameter was measured by 2 examiners to reduce bias.
Results: The intra oral scanner showed the best accuracy of diameter and as the depth increases the accuracy decreases.
Conclusion: Intraoral scanners showed the better accuracy and precision for scanning the post space as compared to extra oral scanner.
