Loading Variables on Implant-Supported Distal-Extension Removable Partial Dentures: An In Vitro Pilot Study
Purpose:
The aim of this study was to investigate strain on implants used for adjunctive support of distal extension removable partial dentures.
Materials And Methods:
An implant with strain gauges was used for testing purposes in two positions, parallel and inclined. Three loading scenarios--loading apparatus (LA), artificial teeth via cotton roll (CR), and artificial teeth (UT)--were studied and strains compared via the Kruskal-Wallis test (P=.05).
Results:
Strain under CR was significantly larger than UT in parallel (P<.05). However, the opposite was observed in inclined.
Conclusions:
Strain in parallel was smallest for UT, whereas in inclined it was largest for CR.
