A resonance frequency analysis to investigate the impact of implant size on primary and secondary stability

Abstract

Objective: Recent years have seen a rise in the usage of dental implants to restore lost teeth. The stability of a dental implant is the main factor in determining its success. Implant stability is influenced by various factors. Several approaches have been employed clinically to evaluate stability at different time intervals. One non-invasive way to assess implant stability is by resonance frequency analysis. Utilizing the resonance frequency analysis method, this study seeks to understand how implant length and diameter affect primary and secondary stability. Methods: The current prospective study was conducted in the Prosthodontics Department of Institute of Dentistry, CMH Lahore Medical College. The duration of the study was six months. A total of 90 implants of sizes 4.5 x 8.5 mm and 4 x 10mm were placed. Resonance frequency measurements were recorded using OsstellTM AB device for primary stability at implant insertion and at 12 weeks for secondary stability. All the measurements were carried out by only one of the researchers to minimize inter-observer bias. Results: The average primary stability was 70.33±6.60, and the average secondary stability was 71.43±5.44. The data was stratified for age, gender, and implant site, and the mean primary and secondary stability of both sizes didn’t show any statistically significant differences. Conclusion: Without forfeiting implant stability, both implant sizes (4x10mm and 4.5x8.5mm) can be used interchangeably, depending on available space and anatomical constraints. doi: https://doi.org/10.12669/pjms.40.6.8213 How to cite this: Khan MW, Inayat N, Zafar MS, Zaigham AM.
