Influence of prosthesis type and intraoral scanner‐based extraoral scanning protocol on the passive fit of CAD‐CAM verification devices

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the impact of different complete‐arch digital scanning techniques and prosthesis types on the passive fit of computer‐aided design and computer‐aided manufacturing (CAD‐CAM) verification devices. Materials and Methods Two different maxillary master casts with four multi‐unit abutment (MUA) implant analogs (FP‐1 and FP‐3 ...

Assessment of fit accuracy and retentive strength of additively manufactured zirconia crowns luted to Ti‐base abutments with different resin cements: An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study investigated the influence of cement gap size on the marginal and internal fit, and cement gap size and type on retention of additively manufactured zirconia (AM‐Z) crowns on titanium bases (Ti‐base). Materials and Methods A total of 135 zirconia crowns were designed with three different cement gap sizes: 20 µm, 30 µm, and ...

Bond strength enhancement for additively manufactured zirconia: Micro‐retentive design approach

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the effect of digitally designed micro‐retention features on the bond strength of additively manufactured (AM) zirconia copings. Materials and Methods Sixty titanium base abutments (NobelParallel, NobelBiocare), pretreated with 50 µm alumina particles were divided into four groups (n = 15 per group); one group with ...

Effect of material, prosthesis height, and aging on the fracture strength of additively and subtractively manufactured implant‐supported cantilevered prostheses

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to evaluate the inherent and after cyclic loading fracture strength of implant‐supported cantilevered fixed prostheses fabricated from recently introduced additively manufactured (AM) and subtractively manufactured (SM) materials, considering variations in prosthesis height.

A digital workflow for full‐arch implant fixed prosthesis: Clinical application of a 3D‐printed polychromatic flangeless trial denture, anatomic bone reduction guide, and intraoral scanning for definitive prosthesis fabrication

Journal of Prosthodontics, EarlyView.
Abstract This clinical report presents a comprehensive digital workflow for rehabilitating a patient with maxillary terminal dentition using a full‐arch, implant‐supported fixed dental prosthesis (FP‐1). It highlights the integration of a 3D‐printed polychromatic flangeless trial denture and a customized anatomic bone reduction template, enabling ...
