Abstract
This systematic review aimed to evaluate the masticatory, fonetic, aesthetic and psychological functioning of palatal obturator prosthesis fabricated using digital technology in patient with maxillectomy defect. According to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, an electronic search of the PubMed, PMC, Science Direct and Wiley databases was carried out in January 2022. The titles and abstracts of all articles were screened by two independent reviewers. The references of the subsequently selected studies were further screened for potential articles. Assessment of the selected full texts was performed independently according to established inclusion and exclusion criteria. A total of 10 studies were included with total of 251 patients. Obturator Functional Scale (OFS) for evaluation of the function was analyzed in 7 studies. Accuracy and dimensional differencies were analyzed in three other studies. From the limited number of studies, the patients showed good results in all fields of functional outcomes and social acceptance. The OFS scores were comparable with those reported in other studies using conventional method. CAD/CAM also tend to produce more extended dimension compared to original design, meanwhile conventional heat-cured PMMA palatal obturator show an overall reduction in dimensions with no significant difference and constant accuracy. CAD with RP technology in conclusion could possibly be an alternative and feasible method for manufacturing palatal obturators for patients after maxillectomy. It has shown significant clinical value, particularly with excellent accuracy and efficient working time.
