Aim: In this research, we aimed to use an electromyogram to look at the muscle activity of people who were wearing a maxillary class III modification 1 removable partial denture made from two distinct materials: Bre-flex and PEEK.
Subjects and methods: Twenty patients with Kennedy class III modification 1, exhibiting maxillary partial edentulous ridges and a full dentulous mandibular arches, were placed into two similar groups for the fabrication of thermoplastic materials. The Bre-Flex material was given to the first group. The PEEK material was given to the other group. We evaluated the muscular activity of each studied group using an electromyogram at the time of denture insertion, three weeks later, and four weeks later, according to the follow-up recall visit schedule. The data were organized into tables and subjected to statistical analysis.
Results: The two groups' differences regarding muscular activity values were statistically significant
Conclusion: Bre-flex RPD shows better adaptability of the neuromuscular system during follow-up periods.
