Despite its predictability, the technique is not without complications, such as graft material dispersion in the sinus cavity, wound dehiscence, hematoma, fenestrations, oroantral fistulas, epistaxis, acute sinusitis, and Schneider membrane perforations. The treatment of the latter can be complex, and depending on its extent, surgery deferral may be necessary, leading to increased patient morbidity. Case Presentation: A patient with apical surgery underwent sinus floor elevation with a significant Schneider membrane perforation using a new approach involving titanium mesh, resorbable membrane, and xenograft. This allowed the continuation of surgery, reducing the number of interventions and patient morbidity. Conclusions: Despite limitations due to a small sample size, this case report demonstrates that addressing large Schneider membrane perforations and placing implants is effective and predictable using the technology and approach of mesh formwork with titanium.<\/jats:p>","DOI":"10.3390\/reports7040113","type":"journal-article","created":{"date-parts":[[2024,12,12]],"date-time":"2024-12-12T03:52:49Z","timestamp":1733975569000},"page":"113","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Formwork Technique with Mesh in Elevations of Sinus Floors with Large Perforations of the Schneider Membrane: A Case Pilot"],"prefix":"10.3390","volume":"7","author":[{"given":"Erick Rafael Fern\u00e1ndez","family":"Castellano","sequence":"first","affiliation":[{"name":"Department of Surgery, University of Salamanca, 37008 Salamanca, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9938-4187","authenticated-orcid":false,"given":"Cosimo","family":"Galletti","sequence":"additional","affiliation":[{"name":"School of Medicine and Surgery Kore, University of Enna, 94100 Enna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1338-0551","authenticated-orcid":false,"given":"Javier Flores","family":"Fraile","sequence":"additional","affiliation":[{"name":"Department of Surgery, University of Salamanca, 37008 Salamanca, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,12]]},"reference":[{"key":"ref_1","first-page":"e639","article-title":"Alveolar ridge reconstruction with titanium meshes: A systematic review of the literature","volume":"19","author":"Poli","year":"2014","journal-title":"Med.
