FACTORS LEADING TO IMBALANCE IN REMOVABLE PARTIAL METAL PROSTHESES IN ANTANANARIVO AND MAHAJANGA MADAGASCAR
Abstract
The metal partial denture (MPD) is defined as a metal device that restores a partially edentulous arch. It provides dual support for hard (dental) and soft (mucosal) tissues. The aim of this study was to identify the sources of imbalance in the MPD.
An analytical study of 92 practitioners in Antananarivo and Mahajanga, making dental prostheses was carried out in 2023.
It was shown that 38% of the practitioners surveyed had already experienced prosthetic instability at least once.
Several factors were found to be responsible for this imbalance in the MPD, such as: professional status (p=0.02), number of years in practice (p=0.001), practitioners not casting the model (p=0.002), not having a paralleling machine in the dental practice (p=0.001), not tracing the framework (p=0.01), and so on.
In the future, in order to improve the analysis, the sample should be extended to make it more representative.
