The purpose of this study has been the evaluation of extra-short implants (\u2264 6.5 mm in length) that were placed in atrophic and non-atrophic anatomical sites to support the same prosthesis.<\/p>\n<p><strong class=\"sub-title\">Methods:\u00a0<\/strong>For that, a retrospective study was conducted by including complete dentures that were solely supported by extra-short implants in the maxilla and\/or the mandible. Clinical data about patients, implants, anatomy, and prosthesis were obtained. Statistical analysis was performed to assess implant- and prosthesis-survival, changes in the marginal bone level and prosthetic complications.<\/p>\n<p><strong class=\"sub-title\">Results:\u00a0<\/strong>A total of 87 implants in 15 screw-retained complete dentures were assessed. None of the prostheses nor the extra-short implant failed during the follow-up of 27.2 \u00b1 15.4 months. The changes in the mesial and distal marginal bone level were + 0.15 \u00b1 0.51 mm and + 0.11 \u00b1 0.50 mm, respectively. Comparing the implants according to the availability of sufficient bone to place longer implants, indicated the absence of significant differences in the changes of the mesial marginal bone level. However, the changes in the distal marginal bone level showed a statistically significant difference in favor of implants that were placed in non-atrophic sites. Two events of screw loosening were reported that were resolved by retightening the screws.<\/p>\n<p><strong class=\"sub-title\">Conclusion:\u00a0<\/strong>Implant- and prosthesis-related outcomes support the use of extra-short implants in atrophic and non-atrophic site to support complete prosthesis.<\/p>\n<\/div>\n<p><strong>Keywords:<\/strong>\u00a0Full-arch; Implant survival; Marginal bone level; Non-atrophic sites; Short dental implants.[\/vc_column_text][vc_empty_space][vc_column_text css=&#8221;&#8221;]<\/p>\n<h3>Figures<\/h3>\n<div id=\"eng-abstract\" class=\"abstract-content selected\"><\/div>\n<p>[\/vc_column_text][vc_empty_space][\/vc_column][\/vc_row][vc_row content_placement=&#8221;middle&#8221; content_text_aligment=&#8221;center&#8221;][vc_column]<div class=\"qodef-image-gallery qodef-grid-list qodef-disable-bottom-space  qodef-ig-grid-type qodef-four-columns qodef-tiny-space  qodef-image-behavior-lightbox\">\n\t<div class=\"qodef-ig-inner qodef-outer-space\">\n\t\t\t\t\t<div class=\"qodef-ig-image qodef-item-space\">\n\t\t\t\t<div class=\"qodef-ig-image-inner\">\n\t\t\t\t\t\t\t\t\t\t\t<a itemprop=\"image\" class=\"qodef-ig-lightbox\" href=\"https:\/\/www.btitrainingcenter.com\/wp-content\/uploads\/2023\/09\/40729_2023_499_Fig1_HTML.jpg\" data-rel=\"prettyPhoto[image_gallery_pretty_photo-404]\" title=\"&lt;strong&gt;Figure 1&lt;\/strong&gt; Bone-level measurements.
