Denture Retention
Conditions
Brief summary
This study is aiming to evaluate the retention of implant supported mandibular overdenture using two different clip materials namely polyoxymethylene (POM) and poly-ether-ether-ketone (PEEK) on PEEK bar at three-time intervals; immediately after placement, after 3 months and after 6 months.
Interventions
DEVICEPEEK clip
The overdentures were attached with PEEK clip . The retention of overdenture was assessed
DEVICENylon clip
The overdentures were attached with Nylon clip . The retention of overdenture was assessed

| Overdenture retention assessed using Universal Testing Machine (Newton) | From enrollment and after 3 months and finally at the end of treatment at 6 months | Denture resistance corresponding to vertical displacement force was obtained using a universal testing machine (INSTRON, United States) to measure retention. Each patient had his chin securely fixed on a support while seated upright. The attachment portion of the universal machine was adjusted in accordance with the device's bar being securely attached to the denture. The device gradually increased the vertical load by 10 mm per minute until the denture completely fell out of place. A tuck sound can be heard to indicate the load at the dislodgment point. Additionally, the force plot in the recorded computer software data exhibits an abrupt drop (Nexyge; Lloyd Instruments; MT-4.6). Each test was repeated five times to obtain five records, and the mean of these records was calculated. Testing was carried out on the mandibular overdenture after insertion, as well as at 3 and 6 months. |
