Effect of Implant Location on Palateless Complete Overdenture Retention: an Study.

Objectives: The purpose of this study was to evaluate effect of implant location on initial retention values of palateless complete overdentures retained by four o-rings at different inter-implant distances.

Material And Methods: Two standard acrylic models representing completely edentulous maxillary arches were used. Four single piece ball type implants were placed in each model.
