Abstract

Bacteremia—the access of bacterium to the bloodstream—may yield lifethreatening complications The aim of this study was to compare the incidence duration and type of bacterium leading to bacteremia with relation to conventional and computerassisted flapless implant surgeryA total of 377 implants were placed in 68 edentulous jaws using the conventional conventional group or a computerassisted stereolithographic SLA templateguided surgery technique flapless group Bacteremia was monitored from pre and postoperative blood samplesThe duration of the surgical intervention was significantly shorter in the flapless group p = 03510 Baseline samples were sterile Following the 15th minute after the placement of the last implant bacteria were present in 62 and 12  of the patients in the conventional and flapless groups respectively p  00001 relative risk 305 The differences in the incidence of the bacteremia detected at the baseline and 15 min after the last implant placement were statistically significant in the conventional group p = 00001 However no such statistical significance was present in the flapless group Staphylocccus epidermidis Bifidobacterium spp Streptococcus viridans Corynebacterium spp and Streptococcus sanguinis were the isolated bacteriumIrrespective of the utilized technique bacteremia may occur upon the placement of four to eight implants to an edentulous jaw The probability of bacteremia for the patients operated with the conventional technique is however 305 greater than those operated with the flapless techniqueThis study was supported in part by Istanbul University Research Fund Projects 2460 and 19100 Risus Medical Istanbul Turkey Turkish Branch of Thommen Medical Waldenburg Switzerland and DENTSPLY Friadent Turkey The authors thank Prof Dr Tayfun Özdemir Department Chair of Oral Implantology Faculty of Dentistry Istanbul University and Prof Dr Nezahat Gürler Department Chair of Microbiology and Clinical Microbiology Faculty of Medicine Istanbul University for their support in this study Dr Sevda Özel of the Department of Biostatistics and Medical Informatics Faculty of Medicine Istanbul University is also acknowledged for her support in the statistical analysis
