Abstract Summary and ConclusionSummary: Six healthy completely edentulous male patients their age ranged from 50 – 65 years, were selected from the outpatient clinic of Removable Prosthodontics Department, Faculty of Dentistry, Suez Canal University. Each patient received two stages root form titanium implant in the canine area of the mandible. Patients received complete maxillary denture and implant retained mandibular overdenture with locator attachment. Patients’ grouping: All Patients contributed in this study used two different nylon inserts. According to the used nylon insert, grouping was: Group1: All the six patients in this study used blue (extra light retention, 1.2 pounds) nylon inserts for one and two months respectively. Group2: All the six patients in this study used pink (light retention, 2.4 pounds) nylon inserts for one and two months respectively. Between using the blue and pink nylon insert all patients were allowed for two months rest period, where the black processing caps were placed in the metal housing instead of the retentive inserts during the rest period. Summary and Conclusion 95 Surface electromyography (SEMG) was done to evaluate muscle activity of the tested muscles (masseter and temporalis) recordings were performed five times as following: - Baseline record, after complete absence of any discomfort, and patients were presumed to be adapted to their dentures. - Patients were allowed for two months adaptation period after the pickup procedure. - Second and third records respectively, after one and two months of using blue inserts. - Patients were allowed for two months rest period where the black processing caps were placed in the metal housing instead of the retentive inserts. - Fourth and fifth records respectively, after one and two months of using pink inserts. The means of changes were collected, tabulated and statistically analyzed and the following conclusions were obtained: Conclusion: 1- Pink locator nylon inserts showed significantly higher masticatory muscle activity than blue inserts. 2- Using pink locator nylon inserts with only two implants showed economical advantage for elderly people who require less invasive solutions |
