Flexural Strength of Various Provisional Restorative Materials for Rehabilitation After Aging

alexandrossfakianakis shared this article with you from Inoreader Flexural Strength of Various Provisional Restorative Materials for Rehabilitation After Aging via Journal of Prosthodontics Abstract Purpose Durability of provisional restoration is crucial for full-mouth reconstruction, which may be influenced by aging. This study evaluated the effect of aging on the flexural strength of provisional materials for oral rehabilitation. Materials and Methods Bar specimens (2×2×25 mm) were fabricated from CAD-CAM [Vita CAD-Temp® (VC), Telio®CAD (TC), artBloc® (RC)], auto polymerized- [Protemp™IV (PA), Luxatemp® (LA), Unifast™Trad (UA)]. Results TCNG indicated the highest mean of σ (133.49 ±4.32), whereas VCNG indicated the lowest mean of σ (84.62 ±3.73) for non-aging. Upon aging process, TCAG revealed the highest mean of σ (123.11 ±4.55), while VCAG possessed the lowest mean of σ (84.05 ±6.39). Significant differences among various provisional materials were indicated (p = 0.001). Aging significantly affected flexural strength (p = 0.001). Conclusions The CAD-CAM provisional material possessed higher flexural strength than heat-polymerized PMMA and auto-polymerized PMMA, which was suggested as a provisional material for rehabilitation. Aging reduced strength for all materials tested. This article is protected by copyright. All rights reserved View on Web
