“…In such cases, to recreate more favorable conditions, different bone reconstructive techniques have been proposed, including guided bone regeneration (Buser et al, 2002;Chiapasco, Abati, Romeo, & Vogel, 1999;Hämmerle, Jung, & Feloutzis, 2002;Lang, Hämmerle, Brägger, Lehmann, & Nyman, 1994;Simion, Jovanovic, Tinti, & Benfenati, 2001;Urban, Nagursky, Lozada, & Nagy, 2013), maxillary sinus floor elevation (Pjetursson, Tan, Zwahlen, & Lang, 2008;Pjetursson et al, 2009), distraction osteogenesis (Chiapasco, Consolo, Bianchi, & Ronchi, 2004;Chin & Toth, 1996;Jensen, Ringeman, Cottam, & Casap, 2011), and onlay grafting with autogenous bone blocks (Chiapasco, Brusati, & Ronchi, 2007;Chiapasco et al, 2006Chiapasco et al, , 2009Esposito et al, 2008Esposito et al, , 2009Nkenke & Neukam, 2014;Sbordone et al, 2009;Schwartz-Arad, Ofec, Eliyahu, Ruban, & Sterer, 2016;Smolka, 2014;Von Arx & Buser, 2006). Among these, the reconstruction with autogenous onlay bone grafts still represents a versatile and very well-documented procedure (Aghaloo, Misch, Lin, Iacono, & Wang, 2016;Aloy-Prósper, Peñarrocha-Oltra, Peñarrocha-Diago, & Peñarrocha-Diago, 2015;Chiapasco et al, 2006Chiapasco et al, , 2007Chiapasco et al, , 2009, which allows the correction of the majority of defects in different clinical scenarios, with no limitations regarding the defect extent.…”
