The procedure described provides a novel and accessible virtual facebow transfer based on standardized photographs loaded in the virtual articulator module of a computer-assisted design and computer-assisted manufacturing (CAD-CAM) software program for dental applications. The practical application of the technique in a digital workflow is the correct alignment of the digital maxillary cast to the virtual articulator with respect to the patient's planes and the skin markings of the condylar axis.

Clinical Considerations: Conventional facebow records are used to transfer the maxillary cast into the analog articulator. Different reference planes have been described, including the true horizontal or gravity reference plane. A conventional facebow (Kois Dentofacial Analyzer; Panadent) allows the recording of the gravity plane for transferring the maxillary cast into the analog semi-adjustable articulator.

Statement Of Problem: Accurately transferring the maxillary cast to the articulator is an essential step in most prosthodontics procedures in both digital and conventional workflows. Recently, the use of a smartphone 3-dimensional (3D) scanner-based virtual facebow record has been reported, but its accuracy is unclear.
Purpose: The purpose of this clinical study was to compare the trueness and precision of a virtual facebow record made with a smartphone 3D scanner with that of a conventional facebow technique.
Parameters to Improve the Accuracy of Intraoral Scanners for Fabricating Tooth-Supported Restorations.

Objectives: To review the factors that impact the accuracy of intraoral scanners (IOSs) when fabricating tooth-supported restorations.
Overview: Factors can have a different impact on IOS accuracy depending on the scanning purpose. If the goal is to fabricate tooth-supported restorations, it is essential to review the following operator-related factors: IOS technology and system, scan extension and starting quadrant, scanning pattern, scanning distance, and rescanning methods.
The Orientation in Space of the Maxillary Arch: New and Old Devices in the Prosthetic Digital Workflow.

Objective: In extensive prosthetic rehabilitations and in those involving the anterior area, a correct 3D spatial position is of fundamental importance for effective communication between the clinician and the dental technician. The aim of this article is to analyze the different methods used to position in space and/or in an articulator the maxillary arch in analog workflows highlighting shortcomings and difficulties in order to understand how to overcome them when employing digital workflows.
Overview: Traditional mechanical devices, such as anatomical, kinematic, esthetic and postural facebows, have clear indications, but also limitations, especially in cases of skeletal asymmetries.
The Role of Digital Facebow for CAD/CAM Implant-Supported Crowns Workflow.

Article Synopsis
- Recent digital technology advancements in dentistry have improved clinical workflows, particularly in creating custom-made crowns and fixed partial dentures (FPDs) using virtual articulation and digital facebows for personalized CAD settings.
- A case report involving a 68-year-old patient needing a replacement for missing teeth led to the initial plan of an implant-supported FPD using zirconia (ZrO2), but complications due to spatial constraints shifted the focus to porcelain fused to metal (PFM).
- The study found that individually crafted PFM FPDs needed fewer adjustments compared to milled ZrO2 restorations, benefiting from reduced working time and fewer intraoral modifications thanks to data from the digital facebow.
