Evaluation of Dental Prosthesis Colors Using a Neural Network
2020 IEEE 5th International Conference on Signal and Image Processing (ICSIP), 2020One of the most important tasks in the work of dental technicians is to reproduce the color of dental prostheses. Experienced dental technicians can correctly estimate the true color from a photograph of the patient’s teeth taken by the dentist, but this is a very difficult process for inexperienced dental technicians.

Color Stability of Polymers for Facial Prosthesis
Journal of Craniofacial Surgery, 2010Color stability of resin and silicone is an important factor for longevity of facial prostheses. The aim of this study was to evaluate the color stability of resins and silicone for facial prostheses. Three brands of acrylic resin and 1 of facial silicone were evaluated considering pigment incorporation for the colorless materials.

Transesophageal color flow Doppler findings are reported in 36 patients with a St. Jude Medical mechanical mitral valve prosthesis who had no auscultatory evidence for prosthetic valve dysfunction. Multiple jets consistent with mitral regurgitation originating from the central and lateral portion of the prosthesis were found in all patients.

Temporary fixed prosthesis materials and beverage colorants: an in vitro study.
General dentistry, 2023The esthetic outcome of temporary prostheses, especially those in the anterior area, is of primary importance. The purpose of this in vitro study was therefore to evaluate the color stability of 3 temporary restorative materials: self-curing (SC) acrylic resin (Tempron); heat-curing acrylic resin (SR Ivocron); and polymethyl methacrylate resin blocks ...

Technique for superimposing a color slide onto a facial cast to sculpt a facial prosthesis
The Journal of Prosthetic Dentistry, 1989A precise and uncomplicated technique for superimposing a color slide onto a facial cast for sculpting a facial prosthesis of the periorbital region is described. This technique allows making a facial impression with the eye closed. The superimposed slide in full-face and profile views provide a natural appearance to the facial cast.

Safe-zone in total hip replacements (THR) means that the acetabular cup is placed within 30 to 50° of abduction and 5 to 25° of anteversion. To help surgeons with prosthesis placement into the safe zone and real-time prosthesis pose estimation, a femoral head prosthesis with a camera mounted inside is designed.
