Resonance frequency analysis of implants subjected to immediate or early functional occlusal loading. Successful vs. failing implants.

Objectives: The objective of this study was to analyze the development of implant stability by repeated resonance frequency analysis (RFA) measurements during 1 year in 23 patients treated according to an immediate/early-loading protocol. The objective was also to evaluate the possible differences between failing and successful implants.

Material And Methods: Eighty-one Brånemark System implants were placed in 23 patients for immediate/early-occlusal loading in all jaw regions.
