Master Abstract
The aim of this study was to compare between the maximum retentive forces of two conventional prefabricated attachments (Dentium locator and Dentium ball) and the retentive forces of custom made attachments with retention sil material.
Acrylic model simulating an edentulous mandible was fabricated, two implants analogues (Dentium implant analogue) was inserted in the canine region parallel to each other.
Overdenture with metallic occlusal plate was constructed to facilitate the retention test procedure.
Two locator abutments (Dentium locator attachment) was tightened to the implant analogues and their prefabricated attachments (clear locator attachment) were picked up in the overdenture fitting surface.
The maximum retentive forces of the prefabricated attachment were recorded with universal testing machine (Instron universal testing machine). The prefabricated locator attachment was removed and replaced with custom made locator attachment with retention sil material and the maximum retentive forces were recorded.
The locator abutment was removed and ball abutments was tightened to the implant analogues (Dentium ball abutment) and their prefabricated attachments were picked up.
The maximum retentive forces of the prefabricated ball attachment were recorded then the prefabricated attachment replaced with custom made attachment with retention sil material and the maximum retentive forces were recorded.
After 3240 cycles of insertion and removal the highest retentive fore was recorded for the prefabricated locator attachment then the prefabricated ball attachment then the custom made locator attachment and finally the custom made ball attachment.
