Fracture Resistance and Wear Resistance of Esthetic Crowns for Pediatric Population: a Comparative In-vitro Study.
Year: 2024
Type: article
Abstract: Introduction And Objectives: Restoration of extensively decayed primary teeth is a challenging task. Hence full coverage crown restorations become mandatory for teeth with multi-surface carious lesions and teeth that have undergone pulp therapy. Pediatric dentists also report pressure from parents of child patients for an esthetic restoration. The major factors that inuence the nal choice of the restoration are, it's strength to bear the masticatory load and esthetics. Thus, this study aimed to compare the fracture resistance and wear resistance of three preformed esthetic crowns available for primary teeth. The mean force required to fracture the crowns was determined using Materials And Methods: servo hydraulic test. While the wear was noted using the pin on disk wear test machine. The results obtained were statistically analysed. Statistical analysis of the results received was done by using the software SPSS version Statistical Analysis: 20. Results: Fracture resistance Zirconia crowns was signicantly higher compared to the fracture resistance of Figaro crowns and the Biox crowns while no signicant difference was noted in the fracture resistance between Figaro and Biox crowns. No signicant difference was seen in the wear resistance between any of the three groups. Higher fract Conclusion: ure resistance was noted with the preformed Zirconia crowns compared to the garo crowns and Biox crowns which showed their fracture resistance in a comparable range. Thus, Zirconia crowns may be could be considered a better alternative, having promising properties to eliminate the traditional restorations in the coming years.
