简要总结

This is a single-center, ten-year, randomized controlled, split-mouth clinical trial. A total of 164 adult patients requiring full-cuspal coverage onlays will be enrolled. Each participant will receive one milled and one 3-D printed restoration, randomly assigned.

详细描述

Restorations will be evaluated at 1 week, 6 months, and 1-10 years using the revised FDI criteria for indirect restorations. The primary outcome is the survival rate of the onlays.
