Effects of framework design and layering material on fracture strength of implant?supported zirconia?based molar crowns

ConclusionsA framework design with standardized layer thickness and adequate support of veneer by zirconia frameworks, as in the ANA and SUP designs, increases fracture resistance in implant?supported zirconia?based restorations under conditions of chewing attrition. Indirect composite material and porcelain perform similarly as layering materials on zirconia frameworks. (Source: Clinical Oral Implants Research)
