The anatomic reconstruction of maxillofacial defects using maxillofacial prostheses is a challenging process for dentists and patients. However, advancements in digital imaging technologies (DITs) might offer substantial improvements for this scenario, as these techniques combine precision and practicality to acquire a more realistic facial design. The aim of this research was to carry out a literature review on the use of DITs in the manufacture of maxillofacial prostheses. An electronic search was carried out in the PubMed and Scopus databases using the MeSH terms "three-dimensional imaging", "maxillofacial prosthesis", and "dental technology”. Inclusion criteria comprised research articles and systematic reviews published in the last 10 years. A total of 78 entries were found, 30 of which were duplicates After abstract and full-text screening, six studies were included. Computed tomography, 3D photogrammetry, and laser scanners were the most reported techniques. These methods were associated with shorter chair time, more comfort to patients, and better precision and adaption of the prosthesis. The indication and effectiveness of each technique appear to be dependent on the region and type of the maxillofacial defect. Nevertheless, limitations in adequate volume reproduction, color accuracy, and adaptation to soft tissues and muscles were reported. In conclusion, DITs are reliable methods for the manufacturing of maxillofacial prostheses, albeit not exempt from obstacles. [ABSTRACT FROM AUTHOR] |
