New study tests plastic vs. ceramic tooth restorations

This study compares two materials used to make dental onlays (a type of tooth filling for molars): a high-performance polymer called BioHPP and a ceramic called lithium disilicate. Forty participants received onlays made from one of these materials. Researchers will evaluate how well the onlays fit, their color, surface smoothness, and overall performance using standard dental criteria. The goal is to see if the polymer is a good alternative to ceramic for restoring damaged back teeth.
