Do I Need Antibiotics Before Dental Implant Surgery?

Dental implant surgery is a common procedure used to replace missing teeth. While it is generally a safe and effective treatment, there are certain risks associated with the procedure. To reduce the risk of infection, the American Dental Association (ADA) and the American Heart Association (AHA) recommend taking antibiotics before dental implant surgery if you have a prosthetic heart valve, a history of infective endocarditis, a heart transplant, or some congenital heart conditions. The use of prophylactic antibiotics for every implant surgery is not mandatory.

However, antibiotics can be useful in preventing postoperative infections after implant placement. To achieve high survival rates and long-term success of dental implants, antibiotic prophylaxis is recommended. A meta-analysis of studies found that taking a single-dose antibiotic before surgery may reduce the occurrence of implant failures. Administering prophylactic antibiotics before implant surgery can provide significant benefits to patients receiving treatment.

The observed overall reduction in risk supports the use of prophylactic antibiotics in dental implantology. The influence of prophylactic antibiotic administration on postoperative morbidity in dental implant surgery has been studied. To prevent the onset of infection at the implant placement site, prophylactic antibiotics are prescribed to raise the concentration of antibiotics in the blood and reduce the possibility of bacterial proliferation and spread. A two-tailed paired t-test showed a significant difference in the average rates of implant failure between two treatment groups, with an average failure rate of 1.8% among patients with antibiotic prophylaxis and 6.0% in patients without prophylaxis (test t, t %3D 2,562; df %3D 8; P %3D 0.0335).

The RCT group had a hazard ratio (RR) of 0.38 (95% CI: 0.25-0.5) for the use of the preoperative antibiotic. The placement of dental implants with the use of a mucoperiosteal flap does not represent a significant risk of developing bacteremia and, therefore, casts doubt as to whether antibiotic prophylaxis is essential for patients considered “at risk of bacterial endocarditis or other focal infections”. However, dentists' understanding of the use and prescription of antibiotic prophylaxis for implant surgery should be reinforced. More economic evaluation studies should be explored to assess the cost-effectiveness of antibiotics, analyzing whether antibiotic treatment contributes enough to health to justify its costs.

If the type of implant surgery (flap lift, bone site condition or number of dental implants) were detailed, the data related to the prescription of antibiotics for individual implants in mature bone sites with flap lift were recorded. This systematic review aims to evaluate the effectiveness of the use of antibiotics, mainly through administration before and immediately after dental implant surgery. The objective is to use a bactericidal drug that prevents the occurrence of infections in the surgical wound by achieving a concentration of antibiotics in the blood that prevents the proliferation and spread of bacteria. In conclusion, taking antibiotics before dental implant surgery can reduce your risk for infection and improve your chances for successful treatment outcomes.

However, there is no standardized guide on the use of antibiotics in dental implant surgery, which accentuates the need for more research to identify the most effective antibiotic regimen to reduce implant failures.
