The effect of number and distribution of unsplinted maxillary implants on the load transfer in implant-retained maxillary overdentures: an in vitro study.

Statement Of Problem: There is little information as to how the number and distribution of implants affect the amount of load transmitted to the palate in implant-retained maxillary overdentures.

Purpose: The purpose of this study was to evaluate the effect of the number and distribution of dental implants on the load transmitted to the palate.

Material And Methods: Eight implant analogues were placed in a replica of an average sized edentulous maxilla corresponding to the position of canines, first and second premolars, and first molars.
