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

open access: yesJournal 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.

Workflow to facilitate complete denture scanning with an intraoral scanner: A technique report

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Scanning a denture with an intraoral scanner is typically more challenging than scanning a dentate arch. This article describes a novel technique for digitally duplicating a complete denture. The workflow involves scanning an existing denture using an intraoral scanner with the addition of specific markers and subsequently constructing a ...

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

open access: yesJournal 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

open access: yesJournal 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 ...

Effect of margin thickness and cement gap on the fabrication and fit accuracy of additively manufactured crowns in definitive resins with different filler content

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate how commercially available composite resins in varying filler content affect the fabrication and fit accuracy (trueness and precision) of additively manufactured (AM) definitive crowns with different margin thickness and cement gaps by comparing them to subtractively manufactured (SM) polymer‐infiltrated ceramic crowns ...

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

open access: yesJournal 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 ...
