Wired/Classic and Wireless/Periotest “M” Instruments: An In Vitro Assessment of Repeatability of Stability Measurements

This in vitro study evaluated agreement among 10 trained evaluators when assessing implant stability with the Wired/Classic and Wireless/Periotest “M.” A difference of 1 Periotest value (PTV) between the wired (−7) and wireless (−8) instruments was observed for the pretest calibration ring. No significant differences were found between the instruments and for all evaluators for all tests (analysis of variance, P < .05). Each instrument can provide meaningful and reproducible recordings of stability measurements.
