Abstract

Aim : To compare and evaluate the marginal fit and fracture resistance of PEEK material with two other
restorative crowns namely – DMLS (metal-ceramic – cobalt-chromium) & All ceramic
Materials and methods: 35 artificial crownsn were fabricated. 20 samples were earmarked for evaluation
of marginal fit using stereomicroscope and 15 samples were intended for fracture resistance. Materials used
for fabrication of crowns were metal ceramic, all-ceramic, and PEEK materials
Results : There was no statistically significant difference between these materials (P > 0.05). than fracture
resistances were compared.
Conclusion : The marginal fit of all ceramic-zirconia crowns was higher than that of the PEEK and DMLSmetal-ceramic crowns and Fracture resistance of DMLS - metal-ceramic crowns was higher than the fracture
resistance of the PEEK and all-ceramic- zirconia restorative crowns.
