This clinical trial analyzes the bone remodeling and marginal bone loss that occur around conical\u2010connection implants placed equicrestally and subcrestally, assessing the effect of the peri\u2010implant soft\u2010tissue phenotype.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Fifty\u2010one patients received 56 implants of distinct diameters (3.5\u2009mm \u00d8 <jats:italic>n<\/jats:italic>\u2009=\u20096; 4.3\u2009mm \u00d8 <jats:italic>n<\/jats:italic>\u2009=\u200941; 5\u2009mm \u00d8 <jats:italic>n<\/jats:italic>\u2009=\u20099) in the posterior part of the maxilla or mandible. The implants were placed equicrestally, 1\u2009mm subcrestally and &gt;1\u2009mm subcrestally, depending on the initial supracrestal tissue height (STH). After 3\u2009months of non\u2010submerged healing, single metal\u2010ceramic screw\u2010retained implant\u2010supported crowns were placed. Longitudinal measurements of STH, mucosal thickness and keratinized mucosa width (KMW) were made at the time of implant placement (T0), crown placement (T1), and after 3 (T2) and 6\u2009months (T3) of prosthetic loading. At each of these points, a radiographic evaluation of bone remodeling and marginal bone loss was also performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>STH was significantly greater for implants placed &gt;1\u2009mm subcrestally than for those placed 1\u2009mm subcrestally. After 12\u2009months of follow\u2010up, a very significant (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) loss of KMW was observed, in addition to a marginal bone loss of 0.08\u2009\u00b1\u20090.1, 0.15\u2009\u00b1\u20090.2, and 0.14\u2009\u00b1\u20090.2\u2009mm in the groups placed equicrestally, 1\u2009mm subcrestally and &gt;1\u2009mm subcrestally, respectively. After the multiple linear regression, marginal bone loss was found to depend primarily on KMW (<jats:italic>\u03b2<\/jats:italic>\u2009=\u2009\u22120.43), while also being affected by STH (<jats:italic>\u03b2<\/jats:italic>\u2009=\u20090.32) and implant diameter (<jats:italic>\u03b2<\/jats:italic>\u2009=\u2009\u22120.28).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Marginal bone loss may be influenced by the position with respect to the bone crest, as well as the KMW, STH, and implant diameter.
