Therefore, the aim of this study was to evaluate the association between self\u2010reported penicillin allergy and the use of alternative antibiotics with post\u2010implant placement surgical complications, early implant failure, and preloading crestal bone loss (PLCBL).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective cohort study examined dental records of patients who received at least one dental implant. Patients who reported a penicillin allergy were identified as the exposed group, whereas patients without a reported penicillin allergy were selected as unexposed in a 1:2 exposed\u2010to\u2010unexposed ratio. Relevant patient\u2010 and implant\u2010related factors were recorded. Implants were evaluated for postsurgical complications, PLCBL, and early failure. Data were analyzed using bivariate analyzes and mixed\u2010effects regression models.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 179 subjects and 374 implants were evaluated. Early implant failure and surgical complications occurred in 6.1% and 8.0% of implants, respectively, while PLCBL was observed in 32.5% of implants. A higher prevalence of surgical complications and implant failure was observed among patients who reported a penicillin allergy compared with those without a reported allergy (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05). Implants prescribed azithromycin showed a higher prevalence of surgical complications, and those prescribed azithromycin or clindamycin had higher early failure rates compared with penicillin (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05).
