ClinConnect Summary

This clinical trial is exploring different ways to create facial prostheses, which are artificial devices that help replace or cover facial defects like missing ears or noses. Participants will have a 3D scan of their face and the area needing a prosthesis. The study will use this scan to create a virtual model of the prosthesis and then test three different manufacturing techniques to make the final product. These techniques include using a special type of rubber-like material, creating a negative mold, and duplicating a prototype using wax and stone. All prostheses will be carefully colored to blend in with the person's natural skin tone.

To be eligible for the trial, participants need to be between 20 and 60 years old and have specific types of facial defects, whether from trauma, congenital issues, or previous unsuccessful surgeries. Unfortunately, those with certain health conditions, like active tumors or serious illnesses, cannot participate. Throughout the trial, participants will provide feedback on how well the prostheses match their appearance, and the accuracy of the prostheses will be measured using advanced software. This study aims to improve the aesthetic outcomes for people with facial defects, helping them regain confidence in their appearance.
