Abstract
Aim: The aim of this study was to evaluate biting force in completely edentulous patients with a thermoplastic denture versus conventional heat cured resin denture relined with soft liner.
Materials and Methods: 28 completely edentulous patients were randomly chosen. Each patient received two dentures. Group A (patients received a conventional heat cured resin denture relined with Soft liner). Group B (patients received a thermoplastic (nylon) denture). Each patient was allowed to wear each denture for six months with two weeks as a rest period between the two dentures. For each denture, the biting force was measured after one month and after six months of denture placement.
Results: The patients recorded higher biting force with conventional heat cured acrylic denture relined with soft liner (group A) than thermoplastic denture (group B) after one month and six months.
Conclusion: After six months of denture use, patients with a conventional acrylic denture relined with soft liner had a higher biting force than patients with a thermoplastic denture. As a result, it might be regarded a treatment plan alternative based on the nature and quality of the ridge to address the issue of decreasing biting force in elderly individuals.
