Aim: The aim of this systematic review was to determine the advantages of the osseodensification technique for the placement of dental implants with or without immediate prosthetic loading in type III-V bone, in narrow bone crest, in a post-extraction implant site, simultaneously with crestal sinus lift. Methods: An electronic bibliographic search was carried out in the databases PubMed (Medline), Cochrane Library and Scopus, without applying language and time restrictions with respect to the publication dates of the
sources. The articles were selected using different inclusion and exclusion criteria. Randomised controlled clinical trials, cohort studies, case-control studies, cross-sectional
studies were included in this systematic review, and animal studies, ex vivo, in vitro, case reports, systematic reviews and meta-analyses were excluded. Studies in which the osseodensification technique was not performed with Densah burs were excluded. Results: After a thorough evaluation, 10 articles were selected and included in the
qualitative synthesis. Randomised clinical trials were evaluated via the Jadad Scale, cross-sectional studies via the Axis checklist, case-control studies, and cohort studies
via the Newcastle-Ottawa Scale (NOS). Conclusions: The osseodensification technique favors high implant stability values in D3-D5 type bone, < 850 Hu, without presenting an increased risk of bone necrosis due to heat or poor vascular perfusion. This technique is reliable and minimally invasive also in cases of simultaneous implant placement
with crestal sinus lift in moderately and severely atrophic bone, without an increased risk of Schneider’s membrane perforation. Further long-term human studies on the osseodensification technique with Densah drills are needed in the future.
