Objectives The aim of this study was to evaluate the extent and quality of new bone 6 months after sinus lift with biphasic micro‐ and macroporous calcium phosphate combined with fibrin sealant ( MBCP‐FS ) and the 1‐year implant success rate in the augmented site. Material and methods MBCP‐FS was applied to one sinus in 96 subjects requiring augmentation for delayed dental implant placement. In subjects who required bilateral lifts ( N = 33), the MBCP‐FS sinus was randomly selected; the contralateral sinus was grafted with autologous bone (mixed with Bio‐Oss when harvested bone volume was insufficient. Panoramic views were taken periodically prior to and up to 18 months post‐lift. Histomorphometric analysis was conducted on biopsies taken during implant placement 6 months after augmentation. Implant functionality and prosthesis success were assessed clinically 1 year after implant placement. Results In MBCP‐FS sinuses, 20.6 ± 8.5% new, mainly lamellar bone was observed. Implants were placed as planned in 78/85 evaluable subjects (91.8%) 6 months after sinus lift. Graft heights remained stable 1 year after placement; 94.7% (142/150) of implants were functional. The amount and quality of new bone and implant success rates with MBCP‐FS were similar to autologous bone graft (mixed with Bio‐Oss in 30/31 evaluable subjects). MBCP‐FS was safe and well‐tolerated. Conclusions MBCP‐FS is safe and effective in sinus floor elevation for dental implant placement, supporting bone regeneration and with high 1‐year implant success rates similar to autologous bone mixed with Bio‐Oss.
