Materials and Methods: Medically unremarkable 215 patients were included in this study and allocated into 2 groups. The first group consisted of 125 patients (58 females, 67 males, mean age 52 yrs) in whom 445 implants were placed in a 2-stage procedure. These patients received penicillin or clindamycin preoperatively only. The second group consisted of 90 patients (46 females, 44 males, mean age 64.3 yrs) in whom 302 implants were placed. This group received both preoperative (penicillin or clindamycin) and longterm postoperative antibiotics (penicillin 300mg 4 times/day or 150mg clindamycin 3 times/day) for 7 days. Patients returned for postoperative evaluation at 1 wk, 2 wk, and just prior to surgical uncovering. All wounds were assessed for pain, swelling, erythema, and purulence.
