The effect of COVID-19 on dental implant osteointegration was not studied thoroughly. In this retrospective study we compared the success rate of dental implants placed before and after the Pandemic, in patients with various medical conditions. The difference of both of immediate and delayed implantation in relation to COVID-19 was also investigated. Two groups of patients were retrospectively evaluated, the first group consisted of 325 patients who had dental implants before the epidemic of COVID-19, and for two years started from August 2017 till August 2019.The second group consisted of 406 patients who had implant placement after the epidemic from February 2020 to February 2022.

This study showed that COVID-19 infection affects the success of dental implantation, there was decrease in the success of implantation placed at the era of Corona virus pandemic. Immediate implantation showed more successful results. Diabetic and ischemic heart patients were more affected with corona pandemic, the success of dental implantation in this group was decreased. Patients with no previous medical conditions, were also affected with this pandemic. In this study the success of dental implantation was decreased in this group of patients, this could be due to the fact were asymptomatic and did not know they were infected previously, or due to the change in life style with decrease in physical activity and decrease in calcium intake and Vitamin D.
