Simplifying the digital workflow of facial prostheses manufacturing using a three-dimensional (3D) database: setup, development, and aspects of virtual data validation for reproduction

Osseointegrated implant‐retained auricular prosthesis constructed using cone‐beam computed tomography and a prosthetically driven digital workflow: a case report

“…13 Use of optical scanning of the contralateral ear (such as the detailed approach described by Ballo et al), 19 direct and indirect molding 16 have been reported as being clinically useful in creating anatomically and esthetically precise ear replacements, using digital workflows to varying degrees, with varying degrees of accuracy and consistency in regard to faithful reproduction of anatomic features and esthetics. 13,14,16 A specific comparison between conventional and digital workflows was published by Unkovskiy et al 16 This case report compared three approaches to fabricate three separate prostheses: direct mold-making (DMM; similar to our approach), indirect mold-making (IMM), and the conventional use of thermoplastic wax in a three-part stone mold. The authors concluded that IMM provided the best overall result (closest to that of conventional fabrication), and afforded the greatest opportunity for adjustment and color matching.…”

Accuracy Evaluation of a Three‐Dimensional Model Generated from Patient‐Specific Monocular Video Data for Maxillofacial Prosthetic Rehabilitation: A Pilot Study

“…However, these workflows are rarely adopted for tissue parts that are not symmetrical pairs, including the nose, because it is difficult to obtain healthy‐state CT or MRI digital data of patients. Thus, an extraoral 3D scanning system based on structured‐light 3D technology 10,11,36,37 and LS techniques 22,38 has been proposed to obtain digital data of specific sites, even though extraoral 3D scanners have been reported to have limited ability to capture complex details. Additionally, a digital workflow for impressions of the ear using intraoral scanners was recently proposed following improvements in their accuracy, precision, and recognition of potential 39 …”

A simplified CAD/CAM extraoral surgical guide for therapeutic injections

“…The integration of extraoral or facial scanning technology in computer-aided design/computer-aided manufacturing (CAD/CAM) has been utilized in several different health fields, including smile design diagnostics and implantology in dentistry [ 9 10 11 ]. Different methods have been proposed for the alignment of these facial scans and intraoral scans of both dentate and completely edentulous patients [ 12 ].…”
