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.
