• Resumen

  • 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.
