Abstract

Introduction: Electromyography is used to evaluate the muscle activity of temporalis and masseter muscles in a comparative clinical research on effectiveness of masticatory cycle by conventional overdenture and use of overdenture with Hader bar attachment for five years established on a scientific level and is first of its kind.

Aim: Thepurpose of this studyis todeterminethe responseof co-ordinationof stomatognathic systemand the functional status of long-termoverdenture use,which can be recorded inEMG.

Material and Methods: Ten patients were treated with maxillary conventional complete denture and mandibular overdenture. Electrical activity of masseter and temporal muscles were obtained in 3 groups. (Gp. I) After insertion of conventional overdenture with copings; (Gp. II) Overdenture with Hader bar attachment and (Gp.III) five years of use of overdenture with Hader bar attachment.

Results and Conclusion: The mean and standard deviation for all the patients showed an increase in muscular activity of temporalis and masseter muscles after long-term rehabilitation (x = 0.405; 0.407 and s = 0.0668; 0.1344 respectively, p = 0.0042 and 0.0074 which is <0.05). This study concludes that overdenture with Hader bar system, after five years of function provide a sound justification for a viable alternative treatment modality to provide overdenture with attachment service to patients.
