Optimize the strategy of indirect bonded restorations to restore an endodontically-treated molar as a unit

This work focuses on endodontically-treated molars because clinical studies have shown that this tooth group had the lowest probability of survival. To restore these teeth, direct resin-based composites have many advantages but may lead to clinical difficulties for dental practitioners, and are also associated with some major disadvantages. Classical crowns are traditionally recommended to restore indirectly highly damaged endodontically-treated molars. Cuspal coverage has indeed been described as a very important prerequisite to restore those highly damaged molars. However, recent data have challenged some of the broadly accepted guidelines, notably that peripherical preparation and a ferrule effect may not be needed. Developments in bonding strategies have also led to the development of aesthetic and less mutilating partial bonded indirect restorations instead of cemented full-crowns. The global purpose of this PhD thesis is to refine the criteria for the choice of bonding technique, restorative materials and substrate treatment restoring single endodontically-treated molar with indirect bonded restoration. The goal is to contribute to improve the understanding, practicality and efficiency of indirect bonded restoration made in resin-based composite to endodontically-treated molars.
