Obtaining full‐arch implant scan with smartphone video and deep learning: An in vitro investigation on trueness and precision

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the accuracy of complete‐arch implant scans generated by a smartphone camera and a deep learning model. Materials and Methods A deep learning model was trained to generate 3D scans from smartphone videos using a maxillary edentulous model with 6 implants and scan bodies (SBs).

Finite element analysis of primary healing implants with different transmucosal designs

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to assess the response of peri‐implant tissues, both hard and soft, to mechanical stress when using a primary healing implant (PHI) with two different transmucosal profiles: concave (Model A) and divergent (Model B). The investigation also sought to observe bone modeling under post‐extraction conditions.

Effects of autoclave sterilization on the dimensional stability of implant surgical guides: A 3D in vitro analysis

Journal of Prosthodontics, EarlyView.
Abstract Purpose Surgical guides are medical devices used in static implant surgery to replicate the prosthetic and surgical implant position planned with computer‐assisted software before surgery. Their use reduces invasiveness and improves safety and outcomes of implant surgery, provided that their accuracy is ensured from design to manufacturing and

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

Journal 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.

Assessment of impact of a control die on marginal fidelity of milled zirconia crown copings for finishing and polishing

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study evaluated and compared the marginal fidelity of milled zirconia copings before and after finishing and polishing with and without a control die. Materials and Methods This prospective multicenter in vitro trial involved two methods regularly used in two clinics for hybrid and full‐digital workflows.

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

Journal 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 ...
