Fracture resistance of teeth restored with dentin-bonded crowns constructed in a leucite-reinforced ceramic

摘要

Objectives; Laboratory studies and preliminary clinical data have demonstrate satisfactory fracture resistance of all-ceramic crowns placed using a resin-composite luting material and a dentin-bonding system. This study investigates the fracture resistance of crowns constructed in a leucite-reinforced ceramic when placed using a dentin-bonding system and a dual-cure resin composite luting material and compares this with the fracture resistance of field spathic porcelain crowns.
