Abstracts [Antibiotikum_Implantation] 072011

The aim of this study was to attempt to determine the minimum effective regimen of Amoxicillin antibiotic prophylaxis for dental implant surgery. One hundred patients were randomly allocated to four different antibiotic prophylactic treatment groups. At second stage surgery only 2 implants failed in the non-antibiotic group. No statistically significant differences were found in the 4 groups, probably because the limited number of the samples. Until a study with a larger population may definitely rule on the role of antibiotic in oral implant surgery, in may be prudent for the pratictioner to adopt the Single Preoperative Antibiotic Dose as the minimal effective regimen. Retrospective analysis of 521 endosseous implants placed under antibiotic prophylaxis and review of literature. Rizzo S, Zampetti P, Rodriguez Y Baena R, Svanosio D, Lupi SM. Minerva Stomatol. 2010 Mar;59(3):75-88. Abstract AIM: Antibiotic prophylaxis in surgical implants has not a consensus in the scientific world. This is due both to reports and statistical studies with contradictory results, both to the risk of severe anaphylactic reactions and the emergence of antibiotic resistance and, finally, to the lack of published RCTs. The purpose of this study is to retrospectively analyze and assess the success of surgical therapy with endosseous implants inserted under antibiotic prophylaxis at the Department of Oral Sciences "S. Palazzi", University of Pavia. The data presented are compared to those published in international literature. The work is complemented by a statistical data analysis in order to propose a statistically valid judgement on the effectiveness of antibiotic prophylaxis in preventing postoperative infections. METHODS: Retrospective observational study with an average follow-up of 4.5 months, until the abutment connection. Furthermore, after extensive review of the literature, published data are compared with what retrieved in our department. Patients operated consecutively from June 2002 to December 2007. Review of literature data concerning the influence of antibiotic prophylaxis on the implant success.
