NCT03682315

Brief Summary

The study aims to evaluate the clinical and radiological behavior, the histological and morphometrical components, the expression of proteins related to bone formation, and the analysis of markers of reparative mesenchymal stromal cells, after using a biphasic phicogenic biomaterial in comparison with anorganic bovine bone. A randomized split-mouth clinical study is designed to include patients in need of two-stage bilateral maxillary sinus floor elevation. Patients are assigned to receive a mix of autogenous bone and a biphasic phycogenic biomaterial in one maxillary sinus and a mix of autogenous bone and xenograft bovine hydroxyapatite in the other maxillary sinus. Cone-beam computerized tomography (CBCT) scans are performed before sinus floor elevation and 6 months after the procedure to assess the bone gain. Bone core biopsies are obtained at the site of implant placement 6 months after the floor elevation. Histological sections are subjected to histomorphometric and immunohistochemical evaluation of differentiation markers.

Outcome Measures

Primary Outcomes (1)

  • Sinus floor height change

    CBCT scans are performed before the sinus floor elevation and 6 months later before implant placement to calculate vertical bone height change from the crestal bone to the floor of the maxillary sinus

    From surgery to 6 months

Secondary Outcomes (3)

  • Area of new mineralized tissue

    6 months

  • Area of non-mineralized tissue

    6 months

  • Area of remaining graft particles

    6 months
