Correlation between radiomorphometric indices and alveolar bone loss in edentulous arches: An Indian perspective

The Journal of Indian Prosthodontic Society | Volume 20 | Supplement 1 | December 2020 S5 adhesive and 30% mixed failure . The third group repaired with Ivoclar repair kit showed 100% mixed failure in ceramic samples(CIII) and the cobalt-chromium (MII) group showed 80% mixed and 20% adhesive failure. Failure type among the three groups was tested by Chi-square test. It was found that significant difference in the failure mode existed among the three sub-groups of both ceramic and cobalt-chromium.(p<0.05). Conclusion: The surface modified with intraoral sandblaster and repaired with Ivoclar repair kit showed the most favorable results for both shear bond strength and the failure mode among the ceramic and cobalt chromium samples . The surface modification had a great role in improving the bond strength of composite repair material to metal ceramic restoration and the failure mode improved from adhesive failure in the control group to a greater proportion of mixed failure in the samples repaired with Ivoclar repair kit after surface modification.
