Evaluation of the Integrity of Ceramic Laminates After Adhesive Cementation

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives This study evaluated the effects of resin‐based materials on crack occurrence in ceramic laminate veneers (CLVs) after adhesive cementation. Additionally, the polymerization shrinkage stress (PSS) and maximum polymerization rate (MPR) of the resin‐based materials were determined. Materials and Methods Four resin‐based materials were

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.
