Various techniques or devices have been used to measure implant stability such as insertion torque measurement, the Periotest
, implant tapping, and removal torque analysis (2).
Periotest values seem to differ between the gingiva former, abutment placement and after single crown cementation on implants.
Positif Periotest values on implant single crown might be considered normal when the healing abutment measurements range between -3 and 0.

Actually in clinical work, the damping characteristics during loading can be measured using Periotest
An electronic device (Periotest
) has been recommended to monitor initial degrees of implant mobility, but the prognostic accuracy of Periotest
value for the diagnosis of peri-implantitis and early signs of implant failure has been criticized because of the lack of resolution, poor sensitivity, and susceptibility to operator variables .
The mobility was confirmed through Periotest (Figure 2).
Ankylosis and replacement resorption can be diagnosed by equipments like Periotest and the Osstell.
Diagnosis of ankylosis in permanent incisors by expert ratings, Periotest and digital sound wave analysis.
Determination of the tooth mobility change during the orthodontic tooth movement studied by means of Periotest and MIMD (the mechanical impedance measuring device for the periodontal tissue).
Longitudinal measurements of tooth mobility during orthodontic treatment using a periotest.

and Osstell Mentor.
