An interim restoration is often used to assess the patient's functional and esthetic needs for implant-supported complete-arch fixed prostheses. A digital protocol for accurately transferring information from the existing dentition to the interim restoration is required. The purpose of this clinical report was to describe a digital workflow to fabricate an interim fixed restoration by using the vertical dimension of occlusion and occlusal relationship from the original dentition to provide an accurate, efficient, and predictable computer-aided design and computer-aided manufacturing (CAD-CAM) interim complete-arch implant-supported restoration.

The present article describes a step-by-step maximally digitalized workflow protocol with computer-aided design and computer-aided manufacturing (CAD/CAM) in partial-arch edentulous patients rehabilitated with fixed dental prostheses and removable partial dentures (FDPs and RPDs). Facial digitalization, intraoral scans, and functional mandibular movement recordings were used to create a 4D virtual patient on commercially available CAD software. The fixed components including post-and-cores, both metal-ceramic with extra-coronal attachment and monolithic zirconia crowns, and the RPDs were manufactured by computer numerical controlled direct milling.

Aim To evaluate and compare the fracture toughness and flexural strength of interim fixed partial dentures reinforced with carbon, glass, and Kevlar nanofibers. Materials and methods This study explored the effect of reinforcing poly methyl methacrylate with carbon, glass, and Kevlar fibers on its fracture toughness and flexural strength. A total of 120 samples were prepared, divided into two groups of 60 samples each, with one group tested for fracture toughness and the other for flexural strength.

An important step in the workflow for a complete arch fixed implant-supported prosthesis is the fabrication of a prototype resin prosthesis to allow the patient to visualize the definitive treatment outcome and also to use as an interim prosthesis. Producing a prototype prosthesis with the natural appearance of the gingival color and contour has been challenging. Current methods include painted stains, manually applied pink composite resin or autopolymerizing acrylic resin, and multicolored resin blocks, but these are all relatively expensive, have less than optimal esthetics, and are labor-intensive and time-consuming.

Objectives: The influence of printing parameters on the marginal and internal fit of three-dimensional (3D) printed interim fixed partial dentures (IFPDs) has been understudied. This investigation sought to elucidate the impact of printing orientation and post-curing time on these critical factors.
Methods: A total of 260 3-Unit IFDPs were printed using two different resins (130/NextDent C&B MFH and 130/ASIGA DentaTOOTH).

Purpose: To report interim results of a single center, randomized, double-blind, crossover-controlled clinical trial comparing wavefront-guided (wfg) scleral lenses (SLs) to traditional scleral lenses (tSLs) for patients with a history of irregular corneal astigmatism (ICA).
Methods: Thirty-one ICA eyes of 18 participants were reviewed, 23 with keratoconus, six postcorneal refractive ectasia, and two postpenetrating keratoplasty. Patients with corneal or lens opacities were not excluded from participating.
