    A comparison of the accuracy of fit of major connectors in conventional and digital partial denture frameworks: an in vitro study
    (University of the Western Cape, 2025) Naidoo, Keraysha Vorania
    Background: Premature loss of teeth has been attributed to numerous causes. Dentures are the most frequent form of oral rehabilitation approach to ensure the maintenance of function. Currently, dentures are either conventionally or digitally fabricated. Major connectors make up the key apparatuses of a removable partial denture (RPD), and the accuracy of the fit in a conventional and digitally fabricated RPD will impact not only its numerous functions but also the success of the removable partial denture. Aim: The aim of this study sought to compare the accuracy of fit of major connectors in conventional and digitally fabricated upper removable chrome-cobalt partial denture frameworks. Method: An in vitro research design was implemented for this study. This study was conducted on chrome-cobalt frameworks manufactured for a Kennedy class III maxillary RPD. There were two conventional and two digital groups. Ten frameworks were manufactured for each group, totalling 40 frameworks. 7 identified palatal landmarks were designated, namely: incisive papilla; left palatal rugae; left lateral gingiva; palatine raphe; posterior border; right lateral gingiva; and right palatal rugae. The accuracy of fit of the major connectors of each chrome cobalt framework was conducted by superimposing each framework on its respective model and measuring the accuracy of fit at the identified palatal landmarks.
