Adjustment of CAD–CAM crowns with and without a 3D‐printed model: Comparative study of marginal fit

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This study evaluated and compared the marginal fit of CAD–CAM zirconia crown copings with and without a 3D‐printed control model. Materials and Methods This prospective in vitro trial involved 30 zirconia crown copings made from the same STL file. These were divided into two groups.

Fracture load of cantilevered implant‐supported prostheses of varying heights fabricated from additively and subtractively manufactured resins

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose The purpose of this in vitro study was to evaluate the fracture load, both before and after aging, of implant‐supported cantilevered prostheses with different prosthesis heights fabricated additively using an experimental resin and a commercially available resin, or subtractively from a high‐impact polymer composite.

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

open access: yesJournal 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 ...

Effects of high‐speed sintering on the translucency and color of dental zirconia with different shades and yttria contents

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This study evaluated the effects of high‐speed sintering on the translucency and color of various yttria‐stabilized zirconia (YSZ) compositions and identified factors influencing these properties to improve clinical predictability. Materials and Methods A total of 144 disc‐shaped specimens fabricated from 3YSZ, 4YSZ, and 5YSZ pucks in ...

3D assessment of the marginal and internal gap and fracture load of ceramic surveyed inlays designed for removable partial denture support: An in vitro comparative study

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To assess the internal and marginal gaps and the fracture load of different machinable ceramics for an inlay acting as a support for a removable partial denture. Materials and Methods Sixty extracted human teeth (first maxillary premolar) were collected (n = 10 for each group).
