ABSTRACT
Objectives: The Aim Of This Study Is To Compare The Electromyographic Muscle Activity Of Both The Buccinator And Temporalis Muscles In Patients Wearing Implants Supported Mandibular Over-dentures Using Two Different Types Of Attachments Namely:
A) Bar Attachments.
B) Magnet Attachments.
Materials and Methods: Ten Patients Were Selected Having Completely Edentulous Upper And Lower Arches, Divided Into Two Groups, Group A Having Implant-supported Mandibular Overdenture With Bar Attachment And Group B Having Implant-supported Mandibular Overdenture With Magnetic Attachment. In Both Groups, The Implants Were Placed In The Canine Region, Muscular Evaluation Was Performed In Each Phase During The Study By Using A Digital Electromyogram (EMG)* Muscular Activity, Represented By The Root Mean Square Value (RMS), Was Evaluated.
Results: The Data Obtained From The Present Study Showed That There Was No Significant Difference Between Bar And Magnet Attachments According To Muscular Activity Measured.
Conclusion: Within The Limitations Of This Study, It Was Concluded That:
In Elderly Patients, The Treatment With 2 Inter-foramina Implants Provides Evidence Of Neuromuscular Adaptation Towards Values Of Healthy Dentate, Thus The Known Benefits Of Implant Placement Such As Tissue Perseverance And Improved Function Are Complemented By Improved Neuromuscular Adaptation.
II. There Was No Significant Difference Between Bar And Magnet Attachments Regarding The Muscular Activity Measured.
