“…Autologous bone has been the first grafting material used for this procedure, being regarded for a long time as the gold standard for its osteoconductive, osteoinductive and osteogenetic properties. However, even if autologous bone grafts demonstrated significantly higher new bone formation after sinus augmentation if compared with other bone substitutes (Browaeys et al, 2007 ; Danesh‐Sani et al, 2017 ), their use is associated with major drawbacks such as increased morbidity, limited availability and low dimensional stability over time (Truedsson et al, 2013 ). For these reasons, the possible use and behaviour of alternative biomaterials (including allografts, xenografts, alloplastic grafts, composite grafts, platelet concentrates and growth factors) has been widely investigated in this specific clinical application (Batas et al, 2019 ; Dursun et al, 2016 ; Galindo‐Moreno et al, 2011 ; Monje et al, 2017 ; Stacchi et al, 2017 ).…”
