Association between Implant Primary Stability and Operator Experience - A Retrospective Hospital Based Study

Abstract

Primary stability plays a major role in determining the success of implant therapy. The main aim of this study was to investigate the association between primary stability and operators experience. This retrospective study was conducted among operators who placed implants in Saveetha Dental College, Chennai. Data were reviewed and collected from 86,000 patient records over ten months from June 2019 to March 2020. Data collected was assessed and tabulated using Microsoft excel. The study included 990 implant sites from 476 patients with a mean age of 42.5 years and a gender distribution of 293 males and 183 females. Implants were placed by 125 operators who belonged to different years of study. The gender distribution of the operators included 73 males and 52 females. Data collected was then exported to Microsoft Excel 2010. The collected data were then subjected to statistical analysis using the Statistical Package for Social Science (SPSS). The most frequently obtained primary stability value was 30-40 Ncm with 53.8%. It was observed that clinicians with four or more years of experience place more implants when compared to others with 69.7% of the total study sample. Clinicians with four or more years of experience attain the optimum insertion torque value of 30-40 Ncm. Within the limits of the study, the implants were most frequently placed by students with four or more years of experience and the most frequent primary stability value observed was 30-40 Ncm. Insertion torque value of 30-40 Ncm was obtained by students with four or more years of experience.
