Several treatment options have been proposed, but some of them may require advanced surgical skills to achieve best results. In this article, we present a novel and easier technique to allow implant placing in localized areas of severe atrophy. In a first step, a 4.5-length extra-short (unloaded) implant is placed after a transcrestal maxillary sinus floor augmentation (MSFA). After the gained apical bone consolidation, this &#8220;temporary implant&#8221; is atraumatically removed and a longer and wider definitive implant is placed to support the definitive single restoration. The case of a 45-year-old female treated with this approach is also presented. The patient suffered a severe resorption in the upper right molar area after a tooth extraction. Four months after the &#8220;temporary implant&#8221; placement and MSFA grafting with plasma rich in growth factors and autologous bone, 3 mm of dense apical bone gain could be observed. In a second surgical time, the 4.5 mm-length &#8220;temporary implant&#8221; was removed, and a 5.5 mm-length &#8220;definitive implant&#8221; was placed. This second implant was placed in a denser type 1 (1,000 Hounsfield Unit) new formed apical bone. Four months later, the implant was loaded with a screw-retained crown over a transepithelial (intermediate abutment). After 1-year follow-up, the implant was in health and no mechanical or biological complications were noticed. The satisfactory results of this case encourage the realization of new studies to elucidate its reproducibility.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<p>[\/vc_column_text][vc_empty_space][vc_column_text]<\/p>\n<h3>Figures<\/h3>\n<div id=\"eng-abstract\" class=\"abstract-content selected\">\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\/2021\/08\/10-1055-s-0042-1755557-i2252126-1.jpg\" data-rel=\"prettyPhoto[image_gallery_pretty_photo-3]\" title=\"&lt;strong&gt;Figure 1.&lt;\/strong&gt; Cone-beam computed tomography image.
