LAYERING ZIRCONIA WITH COMPOSITE OR PORCELAIN? AN ANALYSIS OF FRACTURE RESISTANCE
Journal Title: IDA Ludhiana's Journal - Le Dentistry - Year 2017, Vol 1, Issue 3
Abstract
Introduction:Porcelain layered zirconia restorations are aesthetic but have an essential drawback associated of chipping and difficult repair. Indirect composites, on the other hand, when layered have shown higher mean longevity compared to metal-ceramics The present study was carried out to evaluate the fracture resistance of composite layered zirconia crowns compared to porcelain layered zirconia crowns using fracture resistance analysis. Materials and Methods: Zirconia substructures were fabricated and divided into two groups. A static load was applied and the load was recorded until fracture.Results: Fracture resistance of composite layered zirconia crowns show comparable results to that of porcelain veneered zirconia crowns (p=0.628). Conclusion: Composite layering can withstand high occlusal loads similar to the porcelain veneered zirconia crowns with no significant difference with the added advantage of easy and less damaging cohesive repair.
