Research progress on the fabrication of polymer-infiltrated-ceramic-network composite for dental restorations
Polymer-infiltrated-ceramic-network(PICN)composite is a new type of dental restorative material with an interpenetrating network of resin and ceramic phases.It has excellent natural tooth biomimetic properties and good ma-chinability,making it suitable for rapid tooth repair and restoration through chairside computer-aided design/manufactu-ring.Thus,PICN composite has become a hotspot of research and application.Their comprehensive properties(including mechanical and aesthetic properties)can be controlled through appropriate component design,optimized preparation,and surface modification.This work performs a comprehensive review of the research progress on the fabrication of PICN composites,focusing on the state-of-the-art fabrication of porous ceramics,resin infiltration,and curing and providing a fresh perspective on the future development and research emphasis in this field.
