(2) Methods: Patients who received simultaneous lateral sinus floor augmentation and implant placement were included. Subjects were divided into two groups according to the grafting material, namely xenograft or blood clot, and into sub-groups based on the residual alveolar bone height (RABH) below the maxillary sinus, namely 4 to 6 mm or &gt;6 mm. Kaplan\u2013Meier survival estimates were calculated for each material group and for each sub-group at 1, 3, and 6 years. (3) Results: In total, 289 implants inserted in 136 patients with a one-stage procedure were considered. A total of 35 failures were registered. Overall survival rates were 94.2% for xenograft and 85.9% for blood clot alone at 1 year, 91.1% and 81.6% at 3 years, and 91.1% and 78.7% at 6 years. (4) Conclusions: In patients with 4\u20136 mm RABH, graftless interventions exploiting blood clot alone were not as successful as those using xenograft. When the RABH is low, sinus floor augmentation associated with grafting materials should be preferred whenever possible.<\/jats:p>","DOI":"10.3390\/ma14102479","type":"journal-article","created":{"date-parts":[[2021,5,11]],"date-time":"2021-05-11T11:30:16Z","timestamp":1620732616000},"page":"2479","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Clinical Outcome of Dental Implants after Maxillary Sinus Augmentation with and without Bone Grafting: A Retrospective Evaluation"],"prefix":"10.3390","volume":"14","author":[{"given":"Gianluca Martino","family":"Tartaglia","sequence":"first","affiliation":[{"name":"Department of Biomedical, Surgical and Dental Sciences, University of Milan, 20122 Milan, Italy"},{"name":"Fondazione IRCCS C\u00e0 Granda, Ospedale Maggiore Policlinico, 20122 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3739-1490","authenticated-orcid":false,"given":"Pier Paolo","family":"Poli","sequence":"additional","affiliation":[{"name":"Department of Biomedical, Surgical and Dental Sciences, University of Milan, 20122 Milan, Italy"},{"name":"Fondazione IRCCS C\u00e0 Granda, Ospedale Maggiore Policlinico, 20122 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen Thaddeus","family":"Connelly","sequence":"additional","affiliation":[{"name":"San Francisco Veterans Affairs Health Care System, Department of Oral &amp; Maxillofacial Surgery, University of California, San Francisco, CA 94143, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlo","family":"Maiorana","sequence":"additional","affiliation":[{"name":"Department of Biomedical, Surgical and Dental Sciences, University of Milan, 20122 Milan, Italy"},{"name":"Fondazione IRCCS C\u00e0 Granda, Ospedale Maggiore Policlinico, 20122 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0328-470X","authenticated-orcid":false,"given":"Davide","family":"Farronato","sequence":"additional","affiliation":[{"name":"Department of Medicine and Surgery, School of Dentistry, University of Insubria, 21100 Varese, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7866-5024","authenticated-orcid":false,"given":"Silvio","family":"Taschieri","sequence":"additional","affiliation":[{"name":"Department of Biomedical, Surgical and Dental Sciences, University of Milan, 20122 Milan, Italy"},{"name":"Dental Clinic, IRCCS Istituto Ortopedico Galeazzi, 20161 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"7","DOI":"10.1111\/prd.12157","article-title":"Geriatric periodontology: How the need to care for the aging population can influence the future of the dental profession","volume":"72","author":"Lamster","year":"2016","journal-title":"Periodontology 2000"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"119","DOI":"10.1111\/j.1365-2842.2012.02316.x","article-title":"Interactions between occlusion and human brain function activities","volume":"40","author":"Ohkubo","year":"2012","journal-title":"J.
