Infection of the dental implant surgery area caused by microbe is an important reason for early failure of dental implants.On the one hand,oral microbe can migrate to the surgery area with saliva and cause localized infection.On the other hand,it can also cause transient bacteremia by entering the circulatory system,and even lead to systemic diseases such as endocarditis in severe cases.The oral cavity contains a large number of microorganisms,and most of the dental implant surgeries are performed in the outpatient department,reducing pathogenic microorganisms in the implantation area is crucial.Although achieving a completely sterile environment is challenging,strict aseptic procedures and appropriate pre-and post-operative care can minimize the risk of complications.Additionally,by analyzing microbiology,selecting targeted antibiotics,and improving perioperative care,the treatment outcomes can be further optimized,thereby increasing the success rate of implants.
