Abstract

Purpose: The aim of this in vitro study was to evaluate reliability of the Periotest and Osstell Mentor in assessment of periimplant vertical and circular bone loss.

Materials and Methods: Sixteen dental implants were embedded into acrylic resin blocks. The portion of resin around the implant neck was successively removed to mimic periimplant vertical and circular bone loss. Measurement values of 2 devices were compared by assessing the change of Periotest value (PTV) and Implant Stability Quotient (ISQ) values, by calculating correlation analysis and by means of regression analysis referring to increasing bone loss.

Results: Both devices were able to discriminate differences of circular bone loss. However, PTVs were not noticeably changed in buccal, buccal-mesial, and buccal-mesial-distal bone loss. The differences in buccal and buccal-mesial bone loss were not discriminated by Osstell Mentor. As the range of bone loss was increased, there was a noticeable correlation of the PTV and ISQ values.

Conclusions: The results of this study suggest that both diagnostic devices for implant stability are useful in detecting the circular bone loss. However, the clinical reliability of both devices for detecting the partial vertical bone loss is low.
