Do the printing orientation angle and layer thickness influence the radiopacity of 3D‐printed dental resins?

Journal of Prosthodontics, EarlyView.
Abstract Purpose This in vitro study aimed to evaluate the effect of layer thickness, printing orientation angle, and resin type on the radiopacity of 3D‐printed dental resins. Materials and Methods Three dental 3D‐printed resins (VarseoSmile TriniQ, Crowntec, and Primeprint Temp) were investigated using two‐layer thicknesses (50 and 100 µm) and three ...

Comparison of tooth fracture load between different conventional and CAD‐CAM denture base materials

Journal of Prosthodontics, EarlyView.
Abstract Purpose To assess the fracture load at the tooth‐denture base interface in dentures fabricated using three different production methods: compression mold, computer‐aided design and computer‐aided manufacturing (CAD‐CAM) milled (monolithic and bonded), and 3D‐ printed dentures (monolithic and bonded).

Effectiveness of plasma‐enhanced chemical vapor film in surface treatments of resin‐matrix ceramics to preserve optical characteristics after different aging processes

Journal of Prosthodontics, EarlyView.
Abstract Purpose The aim of this study was to evaluate the surface roughness and optical characteristics of three ceramics with resin matrix for computer‐aided design and computer‐aided manufacturing, after different surface treatment protocols associated or not with the application of film deposition by plasma‐enhanced chemical vapor deposition (PECVD)

Does treatment‐induced surface roughness of 3 mol% yttria‐stabilized tetragonal zirconia polycrystals influence the wear of opposing restorative materials? An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to investigate whether different surface treatments applied to 3 mol% yttria‐stabilized tetragonal zirconia polycrystals (3Y‐TZP), with comparable mean roughness (Ra) values, result in comparable values of additional surface roughness parameters, and to evaluate the influence of zirconia surface topography on vertical ...

Mystery and misery of locally‐delivered drug therapy in periodontics. Historical concepts and current state

Periodontology 2000, EarlyView.
Abstract The primary objective is to critically analyze approaches to local therapy for periodontal disease, particularly in light of its well‐established systemic implications. We specifically address common misconceptions and overestimations regarding the potential of local treatments in contrast to their actual clinical effectiveness.
