Implant mobility is an essential clinical characteristic that should be monitored continuously during the maintenance phase. It may be a critical indication of fixture health. In the Limor Avivi research [6], all 42 monitored implants were clinically asymptomatic and immobile. In our study, implant mobility was measured using the clinical implant mobility scale at the time of implant insertion, second stage surgery, and the first and third months following crown cementation. All of the implants were clinically immobile [Table/Fig. 14].

PERIOTEST is an electronic instrument that measures an implant's mobility by monitoring how the peri-implant tissues react to a specific impact load [7]. It assesses the damping-like features of the tissues immediately adjacent to the implants, identifies micromobility caused by the elasticity of the surrounding bone, and evaluates the osseointegration of dental implants [7]. The PT values vary from -8 to +50, with values beyond 20 being unimportant in implantology [7]. The lower the PT, the greater the stability damping effect. Negative readings are typically considered positive and suggest that the implant is well osseointegrated [1,7]. In Alexandera Behneke's research [3], the periotest readings were negative, with a median of (-4.0) following prosthesis insertion. After the third month after crown cementation, we examined implant mobility with PERIOTEST, and the mean PT value was (-01.6), indicating well-osseointegrated implants [Table/Fig-13]. These findings were consistent with the preceding investigation.

Summarize

Implant Mobility and Fixture Health Monitoring

• Implant mobility is a critical indicator of fixture health and should be continuously monitored during maintenance.
• In a study, all 42 monitored implants were clinically asymptomatic and immobile.
• The study used the clinical implant mobility scale to measure implant mobility at various stages, including implant insertion, second stage surgery, and the first and third months after crown cementation.
• The peri-implant tissues (PT) react to a specific impact load, assessing damping-like features and evaluating osseointegration.
• Negative readings indicate well osseointegration, as seen in Alexandera Behneke's research.
• After the third month after crown cementation, the mean PT value was (-01.6), indicating well-osseointegrated implants.
