Each patient received at least one implant of each diameter (\u00d83.3 and \u00d84.1\u00a0mm), placed either in the maxilla or mandible to support single crowns. A total 44 implants (22 NDIs and 22 RDIs) were placed and included in the study. Twenty\u2010one implants were placed in the premolar, whereas 23 were placed in molar areas. Radiographic evaluations to access the MBL were performed immediately after implant placement, 1 and 3\u00a0years after implant loading. Peri\u2010implant clinical variables including probing pocket depth (PPD) and bleeding on probing (BoP) were obtained after crown delivery, 1 and 3\u00a0years after loading. Furthermore, the survival and success rates of the implants and prosthesis were also evaluated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Twenty patients were able to complete the study.

BoP was present at 15% and 10% of NDIs and RDIs, respectively, at 3\u2010year follow\u2010up. PPD &gt;5\u00a0mm was observed in 5% and 0% of the implants of NDIs and RDIs, respectively, at 3\u2010year follow\u2010up.
