Abstract

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.

无牙弓放射形态测量指标与牙槽骨丢失的相关性:印度视角

印度口腔修复学会杂志|第20卷|增刊1 | 2020年12月S5粘接剂和30%混合失效。第三组用Ivoclar修复试剂盒修复，陶瓷样品(CIII) 100%混合失效，钴铬(MII)组80%混合失效，粘结失效20%。三组间的失败类型采用卡方检验。陶瓷和钴铬三亚组的失效模式存在显著差异(p<0.05)。结论:口腔内喷砂器表面修饰和Ivoclar修复试剂盒修复的陶瓷和钴铬样品在剪切结合强度和破坏模式方面效果最好。表面改性对复合修复材料与金属陶瓷修复体的结合强度有很大的提高作用，表面改性后Ivoclar修复套件修复样品的破坏模式由对照组的粘结破坏改善为混合破坏的比例更大。DOI: 10.4103/0972-4052.306352在无牙弓放射形态测量指标和牙槽骨丢失的相关性:一个印度的观点
