Abstract
The fracture strength of implant supported zirconia-titanium base (Zi-Ti) base restorations with and without modification of submucosal cervical contour is of interest to dentists. 80 zirconia specimens were adjusted onto the Ti-base. One category consisted of specimens that underwent modification. Other category consisted of abutments without modification. There was polishing and recon touring at the interface of Zi-Ti base in cervical regions. Using the universal testing apparatus fracture resistance was assessed for every sample in every category in Newtons (N). The fracture strength of abutments with modification ranged between 4465.79 - 6523.50 N with mean value of 5604.24 ± 497.62 N. On the other hand, values of fracture strength varied between 5511.42 - 7064.33 N. in abutments without modification with mean fracture strength values of 6265.95 ± 331.61. It was observed that the fracture strength was lesser in abutments that underwent modification.
