Abstract

Purpose: was to evaluate the effect of using two different types of overdenture attachment systems (ball and socket and magnet attachments) in single implant retained mandibular overdentures by measuring electromyographic activity and masticatory efficiency of the patient’s masseter and temporalis muscles. Materials and methods: Ten completely edentulous patients with ages ranged from 55-65 years. Each patient received overdentures retained by midline implant with two different types of attachments; ball and socket attachment (group A) and magnet attachment (group B). The masticatory efficiency and the electromyographic activity of the masseter and temporalis muscles were evaluated after one month and three months from attachment connection for both groups. Results: The results of this study showed that there were significant decrease in the measurement of masticatory efficiency and electromyographic activity of the masseter and temporalis muscles after one month from using ball and socket attachments. While, there were insignificant differences in the measurements of masticatory efficiency and electromyographic activity of the masseter and temporalis muscles after three months from delivery for both ball and socket and magnet attachments. Conclusion: The masticatory efficiency and electromyographic activity were more improved after using ball and socket attachments compared to magnet attachments.
