Radiographic (Marginal bone loss) and clinical outcomes (Bleeding on Probing, probing pocket depth, plaque accumulation, incidence of peri\u2010implantitis and peri\u2010implant mucositis as well as prosthetic complications) were collected and compared at 1, 2, 3, and 5\u2009years. A linear mixed model was used to evaluate the differences between groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Five years after treatment, the MBL change was not significantly different between the groups at any point. The MBL was 0.23\u2009\u00b1\u20090.64\u2009mm (AL) and 0.23\u2009\u00b1\u20090.29\u2009mm (IL). The bleeding on Probing was 44% (AL) and 45% (IL) (<jats:italic>p<\/jats:italic>\u2009=\u2009.89). The mean probing depth was 2.91\u2009\u00b1\u20091.01\u2009mm (AL) and 3.51\u2009\u00b1\u20090.67\u2009mm (IL). This difference between the groups was statistically significant but clinical insignificant. Presence of plaque was slightly higher (<jats:italic>p<\/jats:italic>\u2009=\u2009.06) in the IL group (34.4%) compared with the AL group (26.3%).
