Crestal Bone Loss in Implants Postloading and Its Association with Age, Gender, and Implant Site: A Retrospective Study

We evaluate crestal bone loss in implants after loading and bone loss associated with age, gender, and implant site. This retrospective study was conducted in the Department of Prosthodontics, Saveetha Dental College, India. We obtained ethical clearance from the Scientific Review Board at the college. Data were collected from 86,000 patients who visited Saveetha Dental College between June 2019 and March 2020. From these, we retrieved data from 335 patients, in whom implants were placed during this time frame. We tabulated data using the Statistical Package for the Social Sciences (IBM; Armonk, NY), ver. 20 for Windows. Chi-squared tests determined association among bone density, implant site, crestal implant position, and primary implant stability. We observed significant correlation between age and crestal bone loss (p = 0.019), but not between gender (p = 0.792) nor implant site (p = 0.223) with crestal bone loss.
