Kashani H, et al. - In this randomized clinical trial, researchers analyzed 447 subjects who received 963 implants to study the outcome of a single preoperative dose of antibiotics on the early implant failure rate in the county council of West Sweden, Vastra Gotaland. They observed the failure of 12 implants in 11 patients for the AB group (subjects receiving a single dose of preoperative antibiotics) and 32 implants in 29 cases for the noAB group (receiving no antibiotics earlier to implant surgery). Lower implant failure of 2.2% in preoperative antibiotics, AB group as compared to 7.5% in the noAB group was noticed.
