Antibiotic Prescribing Habits of Oral and Maxillofacial Surgeons in Conjunction With Routine Dental Implant Placement

Purpose: Although various prophylactic systemic antibiotic regimens have been suggested to minimize failure after dental implant placement, the role of antibiotics in implant dentistry is still controversial. The purpose of the present survey was to determine the current antibiotic prescribing habits of oral and maxillofacial surgeons in conjunction with routine dental implant placement to determine whether any consensus has been reached among such practitioners. Materials and Methods: An electronic survey was sent by electronic mail to all members of the American College of Oral and Maxillofacial Surgeons. The questions asked were related to whether antibiotics were routinely prescribed either pre- or postoperatively during routine dental implant placement, and, if so, what antibiotics, dosage, frequency, and duration were used. The survey participants were also asked to specify whether they were in solo private practice, group private practice, academia, military, or other. The results were tabulated and analyzed using SAS software. Descriptive statistics and chi(2) analyses were used. Results: A total of 217 members responded to the survey. Overall, 112 of 217 (51.6%) prescribed antibiotics preoperatively (95% confidence interval [CI] 50.0 to 58.2%) and 152 of 213 (71.4%) prescribed antibiotics postoperatively (95% CI 65.0 to 77.0%) during routine dental implant placement. Also, 72 (34%) indicated that they prescribed antibiotics both pre- and postoperatively. The most common preoperative regimen used was amoxicillin 2 g given 1 hour before the procedure (32%, n = 36). The most common postoperative regimen used was amoxicillin 500 mg 3 times daily for 5 days (53%, n = 81). Conclusions: We found no consensus among oral and maxillofacial surgeons regarding the use of antibiotics in association with routine dental implant placement, the type of regimen to use, or whether such use is even effective in preventing early implant loss. Furthermore, most of the antibiotic regimens being used are not in accordance with the recommendations current in the published data. (C) 2015 American Association of Oral and Maxillofacial Surgeons
