November 17, 2024 updated by: Sameh Abou-steit, Cairo University

Clinical Assessment of Endodontically Treated Posterior Teeth Prepared With Two Occlusal Designs and Two Ceramic Full Coverage Restorations (Randomized Clinical Trial)

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).
