This exposure immediately allows the formation of bacterial colonization to occur on the implant and periimplant environment. The bacteria associated with this healing process vary considerably from one patient to another. The overall clinical success and limited research suggest that a flora commonly associated with health establishes after the periimplant tissue has formed a sulcus. During the early post surgical period, implant healing is at a vulnerable stage. In cases of early failure with this treatment approach an association has been shown to exist with pathogenic periimplant bacteria.
Most clinicians arbitrarilly use systemic antibiotics for all one stage surgeries.
Antibiotics of choice are those that will reduce the possibility of post-operative infections. Therefore, in the Penicillin group, either Penicillin , Amoxicillin , or Amoxicillin plus Clauvonic Acid are recommended. Dosage will range from 250mg to 500mg every six to eight hours depending on body weight. The duration is generally 7 to 10 days. In patients who have a history of allergy to the Penicillin group, the alternative antibiotics are Erythromycin , 250mg to 500mg, every 6 hours for 7 to 10 days or Ciprofloxacin, 200-750 mg every 12 hours for 7 to 10 days.
