Abutment tooth and base movement witl attachment retained removable partial dentures

Abstract

Using a laboratory model for the distal extension removable partial denture situation, the effect of resilient and rigid precision attachment retainers on abutment tooth and denture base movement was studied. It was found that both abutment tooth and denture base movement was least with the rigid and semi-precision attachments used compared to the resilient attachments. Abutment tooth movement was generally towards the mesial, except for the C and L attachment which produced distal movement.
