Comparative Evaluation of Masseter and Buccinator Muscle Activity using Electromyography in Denture Wearer and Nondenture Wearer by Fabricating Dentures with Neutral Zone Technique – An In vivo Study

Abstract

Introduction: The objective of this study was to analyze buccinator and masseter muscle activity in previous denture wearer and nondenture wearer wherein dentures were constructed with neutral zone technique; however, complete dentures for patients with no history of previous dentures can be made with a neutral zone technique for improved stability. Methodology: A total of 50 patients were included in this study among which, Group A consisted of a total of 25 patients, who were old denture wearer and for whom a new denture was fabricated with the neutral zone technique. Group B consisted of 25 patients who were first-time denture wearer for whom a new denture was fabricated with a neutral zone technique. Results: The muscle activity does not significantly differ in previous denture and nondenture wearers. However, complete dentures for patient with no history of previous dentures can be made with a neutral zone technique for improved stability. Conclusions: Buccinator and masseter muscle activities significantly differ due to morphological changes that occurred in denture wearers and nondenture wearers.
