After 4\u00a0months of healing, flaps were elevated, and two implants were installed at each side of the mandible, one in the premolar and the other in the molar regions. Four different types of healing abutments were positioned on the top of each implant: (i) titanium (Ti); (ii) <jats:styled-content style=\"fixed-case\">PEEK<\/jats:styled-content> material bonded to a base made of titanium (Ti\u2010P), randomly positioned in the premolar region; (iii) <jats:styled-content style=\"fixed-case\">PEEK<\/jats:styled-content>, pristine (P); and (iv) <jats:styled-content style=\"fixed-case\">PEEK<\/jats:styled-content>, roughened (P\u2010R), randomly positioned in the molar region. The flaps were sutured to allow a non\u2010submerged healing, and after 4\u00a0months, the animals were sacrificed and ground sections obtained for histological evaluation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A higher resorption of the buccal bone crest was observed at the <jats:styled-content style=\"fixed-case\">PEEK<\/jats:styled-content> bonded to a base made of titanium abutments (1.0\u00a0\u00b1\u00a00.3\u00a0mm) compared to those made of titanium (0.3\u00a0\u00b1\u00a00.4\u00a0mm). However, similar dimensions of the peri\u2010implant mucosa and similar locations of the soft tissues in relation to the implant shoulder were observed.
