Book Description
Obtaining and maintaining implant stability are prerequisites for the clinical success of implant prostheses. Since primary stability is a direct consequence of bone-implant contact, it depends on bone density, surgical technique, and macroscopic and microscopic morphology of the implant used. Primary stability can be either measured by insertion torque or ressonance frequency analysis, but no relation between these two is clearly described. The objective of this study was to evaluate the statistical correlation of primary stability through ressonance frequency analisys (RFA) and manual torque of insertion through literature review and case series study.This study was conducted on a post-graduate clinic (CLIVO- Rio de Janeiro,Brazil), where fourteen dental implants had their manual torque and RFA measured using a manual torque device during instalation. RFA measured the Implant stability Quoeffcient(ISQ) using a smartpeg after instalation in 5 different positions ( bucal, lingual, occlusal,mesial and distal).All of the fourteen implants had the same conical connection and were placed in the mandible or maxila. The mean ISQ measurements and manual torque were submitted to statistical analysis to determine a possible correlation.We evaluated 13 implants, 9 implants performed in female patients and 4 male patients, 5 in maxilla and 8 in mandible. For the study, internal connical connection dental implants were used. In order to verify the correlation between TORQUE and ISQ, the statistical software.
