“…The presence of a radiopaque area entirely surrounding the implant apex was observed post‐surgery in cases treated with either BC alone or in combination with an adjunctive biomaterial. The isolation of a BC with a trephine drill at the implant site and its implosion with osteotomes to obtain the elevation of the maxillary sinus floor has been already described in association with delayed (Fugazzotto & De Paoli, ; Kolerman, Moses, Artzi, Barnea, & Tal, ) and immediate implant placement (Soltan & Smiler, ; Teng et al, ). On the other hand, the effectiveness of the association of BC with graft materials such as ß‐TCP, DBBM, DPBM, and S‐HA is well documented for tSFE procedures and immediately followed by implant positioning (Farina et al, , ; Franceschetti et al, , , ; Trombelli et al, , ; Trombelli, Minenna, Franceschetti, Minenna, Itro, et al, ).…”
