![]() Authors emphasized on the need of digital library for prostheses selection, especially for bilateral defects. ![]() For unilateral defects, CAD was used to mirror the healthy tissue over to the defect side. For auricular prostheses, laser scanning was most preferred. Moisture and muscle movement affected the overall fit especially for prostheses directly designed and printed. Designing and printing the mold was more preferred. After image processing, computer aided design (CAD) was used to design and merge the prosthesis to the peripheral healthy tissue. For nasal prostheses, Common Methods of data acquisition mentioned were computed tomography, photogrammetry and laser scanners. Thirty-nine selected papers from 1992 to 2019 were then read and categorized according to type of prosthesis described in the papers. Articles were searched from Scopus, PubMed and Google Scholar based on the predetermined eligibility criteria. Secondary objectives were to analyze the methods of data acquisition recorded with challenges and limitations documented with various software in the workflow. The objective of the review was to primarily identify the recorded cases of orofacial rehabilitation made by maxillofacial prosthetics using computer assisted 3D printing. A systematic review was conducted in early 2019 to evaluate the articles published that dealt with digital workflow, CAD, rapid prototyping and digital image processing in the rehabilitation by maxillofacial prosthetics. ![]()
