Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study was to assess the impact of flat occlusal preparation design (FOD) of endodontically treated molars on the fracture resistance and distribution of stresses among a ceramic crown-molar structure when compared to two planes occlusal preparation design (TOD).
