Radiographs examined crown height, crown-to-implant ratio, and marginal bone loss at baseline, six months, and 12 months. The correlation between crown height and marginal bone loss was examined.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The average crown-to-implant ratio was 1.8:1 in the study. Implant crown heights above 10 mm showed increased marginal bone loss. The mean marginal bone loss at six months was 0.25 \u00b1 0.08 mm, rising to 0.38 \u00b1 0.10 mm at 12 months. Implants with crown heights \u226410 mm had considerably reduced bone loss (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.05) compared to implants with greater crown heights.
