Relationship between contact time measurements and PTV values when using the Periotest to measure implant stability.

摘要: PURPOSE: The Periotest is an electronic instrument that has been advocated for the measurement of implant stability and osseointegration. aims this investigation were to establish relationship between contact time PTV values when was used assess implants in vivo vitro, investigate influence striking height handpiece length abutment. MATERIALS AND METHODS: accelerometer signal from a captured compared with resulting value. In vitro measurements contract performed on 3-mm abutment had attached 15-mm luted into aluminium block, repeated patient vivo. further made abutments six turn maxilla same patient. standard lengths 3, 4 (x 2), 5.5 7 mm. RESULTS: results indicated there linear value measured Greater scatter data attributed test variables including position, distance, damping as result presence soft tissue. There vitro. CONCLUSION: It can be concluded sensitivity clinical heights angulation limit application diagnostic aid measure stability.
