Pink and White Esthetic Scores of Polymer-infiltrated-ceramic-network and Lithium Disilicate Implant Hybrid Abutment Crowns

Pink and White Esthetic Scores of Polymer-infiltrated-ceramic-network and Lithium Disilicate Implant Hybrid Abutment Crowns: Randomized Clinical Trial

The aim of this study is to evaluate the effect of polymer-infiltrated-ceramic-network hybrid ceramic on pink and white esthetics in comparison with lithium disilicate.

The research hypothesis is that there will be comparable clinical performance results between polymer-infiltrated-ceramic-network and lithium disilicate hybrid abutment crowns.
