Methods: In the displacement group, a localized surgical fracture of the sinus floor achieved through an electromagnetic device results in the distal displacement of the anterior wall. In the filling group, sinus lifting (with lateral access) and grafting with particulate xenogeneic bone substitute was performed. Bone volume beneath the maxillary sinus was investigated with computerized tomography after baseline and postoperative data superimposition. Clinical and radiological outcomes over three years had been evaluated. Results: Forty-three dental implants were selected. The two sinus lift procedures significantly increased the bone volume (p-value \u2264 0.0017) in the displacement group from 1.17 \u00b1 0.34 to 1.53 \u00b1 0.39 cc, with a final bone gain of +0.36 \u00b1 0.17 cc, and in the filling group from 1.24 \u00b1 0.41 to 1.94 \u00b1 0.68 cc, with a bone augmentation of +0.71 \u00b1 0.31 cc. No events of dental implant bulging into the maxillary sinus occurred. Two implants failed early on in the filling group, attesting the 3-year survival rate of 92.6% (CI95%: 82.7\u2013100%). Marginal bone loss at the distal aspect was 1.66 \u00b1 0.72 and 1.25 \u00b1 0.78 mm, respectively, for the displacement and filling groups, with a significant difference (p-value = 0.0497). Conclusion: Results showed a significant and effective bone gain around dental implants at a 3-year survey for both sinus augmented by backward displacement of the anterior wall (+34%) and sinus lifting and grafting with a lateral window approach (+57%).<\/jats:p>","DOI":"10.3390\/ijerph17197199","type":"journal-article","created":{"date-parts":[[2020,10,1]],"date-time":"2020-10-01T11:28:57Z","timestamp":1601551737000},"page":"7199","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Distal Displacement of Maxillary Sinus Anterior Wall Versus Conventional Sinus Lift with Lateral Access: A 3-Year Retrospective Computerized Tomography Study"],"prefix":"10.3390","volume":"17","author":[{"given":"Giovanni Battista","family":"Menchini-Fabris","sequence":"first","affiliation":[{"name":"Department of Multidisciplinary Regenerative Research, Guglielmo Marconi University, Via Vittoria Colonna, 11, 00193 Rome, Italy"},{"name":"San Rossore Dental Unit, Viale delle Cascine 152 San Rossore, 56122 Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paolo","family":"Toti","sequence":"additional","affiliation":[{"name":"Department of Multidisciplinary Regenerative Research, Guglielmo Marconi University, Via Vittoria Colonna, 11, 00193 Rome, Italy"},{"name":"Department of Stomatology, Tuscan Stomatological Institute, Foundation for Dental Clinic, Research and Continuing Education, Via Padre Ignazio da Carrara 39, 55042 Forte Dei Marmi, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giovanni","family":"Crespi","sequence":"additional","affiliation":[{"name":"Department of Stomatology, Tuscan Stomatological Institute, Foundation for Dental Clinic, Research and Continuing Education, Via Padre Ignazio da Carrara 39, 55042 Forte Dei Marmi, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ugo","family":"Covani","sequence":"additional","affiliation":[{"name":"Department of Stomatology, Tuscan Stomatological Institute, Foundation for Dental Clinic, Research and Continuing Education, Via Padre Ignazio da Carrara 39, 55042 Forte Dei Marmi, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberto","family":"Crespi","sequence":"additional","affiliation":[{"name":"Department of Multidisciplinary Regenerative Research, Guglielmo Marconi University, Via Vittoria Colonna, 11, 00193 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1394","DOI":"10.1097\/SCS.0000000000001725","article-title":"Maxillary Sinus Septa and Anatomic Correlation with the Schneiderian Membrane","volume":"26","author":"Rancitelli","year":"2015","journal-title":"J.
