The sites were randomly assigned into two groups of six each: group 1: 2.8 mm neck implants and group 2: neck implants. The parameters plaque index (Pl), gingival index (GI), probing depth (PD), gingival margin level (GML), relative clinical attachment level (r\u2010CAL), and optical density (OD) were measured at loading (4 months) and 12 months after implant placement. The radiographic parameter osseous level (OL) was measured at implant placement, loading, and at 12 months. Analysis of variance and the paired Student <jats:italic>t<\/jats:italic> test were used to detect difference over time and between groups.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> The results showed significant differences (<jats:italic>P<\/jats:italic> &lt;0.05) for both groups for PD, r\u2010CAL, and OL for intragroup comparisons over time.
