Virtual articulation using sequential mandibular intraoral scans and computational functional rotation reference determination—Proof‐of‐concept

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Virtual articulators require accurate spatial orientation of digital casts for meaningful occlusal analysis during prosthesis design. Current methods for establishing this orientation rely on facial scanning, cone‐beam computed tomography, electronic jaw tracking, or arbitrary population–based values. This proof‐of‐concept technique presents a

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.

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

open access: yesJournal 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)

Effects of scanner type and prosthesis design–luting protocol combinations on the passive fit of interim implant‐supported complete‐arch fixed dental prostheses

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the effects of scanner type and prosthesis design–luting protocol combinations on the passive fit of interim implant‐supported complete‐arch fixed dental prostheses (ISCFDPs) fabricated using a non‐calibrated splinting grammetry system (OptiSplint).

Effect of metal framework design on the fracture resistance of implant‐supported metal–ceramic crowns fabricated by selective laser melting

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the fracture resistance of implant‐supported metal–ceramic crowns fabricated using selective laser melting (SLM), according to the metal support height around the screw access hole (SAH) and the substructure design. Materials and Methods Metal–ceramic crowns and rectangular bilayer specimens were fabricated using SLM in two
