Abstract

Purpose: was to evaluate the effect of two different implant attachment designs on retention and Electromyographic activity in narrow implant retained mandibular overdentures. Material and Methods: Ten patients were selected ranging in age from 50-70 years. Each patient received two implants with a narrow diameter placed in the canine region of the edentulous mandible. Patients were divided into two groups: Group I (Ball and socket group): all patients received ball and socket attachments for six months. Group II (Equator Group): all patients received equator attachments for another six months with a one-month washout period. Retention and Electromyographic activity were evaluated at insertion, after three months, and after six months from delivery. Results: The descriptive statistics of retention showed statistically significant difference in the retention values at the three periods of time within the same group and also between the two studied groups at each observation time (p < 0.001 at the three observation times). Regarding electromyographic activity, there was a statistically significant increase in the muscles activity after using attachment in the studied groups. Nevertheless, the comparison between the two groups at the end of follow up period revealed a statistically insignificant difference. Conclusion: Within the limitations of this study, it can be concluded that narrow diameter implants are an effective treatment option that allows us to avoid more invasive procedures. Reduction of retention should be considered when selecting dental attachments. Muscles activity significantly increased after using dental attachments, with no significant differences among the studied attachments (Ball and equator).
