A COMPARATIVE ANALYSIS OF WEAR RESISTANCE, SURFACE HARDNESS AND FRACTURE RESISTANCE OF INTERIM RESTORATION FABRICATED BY CAD/CAM AND CONVENTIONAL METHOD” - AN IN- VITRO STUDY - ORIGINAL RESEARCH

Abstract

Introduction: Fixed Prosthodontics Treatment can only be successful with a good Interim restoration. Increase in demand of cosmetic dental procedures, provisional restorations have become a diagnostic tool rather than a space maintainer. Aims: A Comparative Analysis of Wear Resistance, Surface Hardness and Fracture Resistance of Interim Restoration Fabricated By CAD/CAM and Conventional Method. Materials and Methods:-The present study was a Comparative study. This Study was conducted from 1 year 6 months in Department of Prosthodontics and Crown & Bridge at Institute of Dental Sciences, Siksha ‘O’ Anusandhan (Deemed to be University) Result: The distribution of data for the groups was found to be non-normal, as was seen from histogram and applying tests of normality (Shapiro-Wilk test and Kolmogorov Smrinov test). Conclusion: Mechanical properties hold one of the most important criteria for the longevity of the Interim restorations. Recent advancement and cosmetic needs had led to huge advancement in the materials which are commercially available for temporary restorations. Evaluation of materials is necessary to estimate their mechanical properties so that they can be easily fabricated and used for long term.
