Abstract

A clinical instrument was developed to analyze resonance frequency by using a new unit called implant stability quotient (ISQ). ISQ replaces hertz, which is dependent on the transducer used, and is recorded as a number between 1 and 100, 100 representing the highest degree of stability. The Aim of the current prospective clinical study was to evaluate changes in the post insertion stability of implants following osteotomy site preparation.

In this study 30 implants were placed in healthy adult patients presenting with completely or partially edentulous jaws. After placement of implant with conventional drilling protocol, stability of implant was checked with “RESONANCE FREQUENCY ANALYSIS METER” and the ISQ values were recorded as Smart Peg® was screwed into implant and tightened at 5 Ncm. Transducer Probe attached to RFA meter was held stable at the top of Smart Peg® at a distance of 2-3 mm during pulsing until the instrument beeped and Implant stability quotient (ISQ) value was displayed on the device. All the results were analyzed.

At 1st postoperative week, there was decrease in the mean ISQ values in all the implants (100%) when compared with the mean ISQ values achieved immediately after implant placement. At 4th postoperative week, there was decrease in the mean ISQ values in all implants. At 8th postoperative week, there was an increase in the mean ISQ values in all the implants (100%) when compared with the mean ISQ values obtained at 4th postoperative week. At 12th, 16th and 24th postoperative week, there was increase in the mean ISQ values in all the implants (100%) when compared to the mean ISQ values of the previous follow up. No statistical analysis was done for 1st, 8th, 12th, 16th and 24th postoperative weeks as there were no differences in the values in both the groups.

The existence of a time interval between primary and secondary stability during which the mobility of the implant may increase that leads to decrease in the ISQ values approximately at 3-4 weeks post-surgically.
