In overdentures retained by Locator attachments, the distribution of dental implants had a significant effect on the force measured on the palate of the oral analogue. The measured load was not significantly lower than the eight dental implant design, when the distance between the four dental implants was sixteen or more millimeters, suggesting that the palate of a four dental implant-retained overdenture with a distance of sixteen millimeter or more, does not contribute significantly to the load transfer to underlying hard palate in the in vitro analogue evaluated.
This is based on the study done by Dr. Sahar Damghani, et al entitled “The effect of number and distribution of unsplinted maxillary implants on the load transfer in implant-retained maxillary overdentures: An in vitro study”.
