Clinical Trial Summary

Objectives: The aim of the study was to compare histological and histomorphometric results of six bone substitute materials used as graft in two-stage maxillary sinus augmentation model, after 6-month-healing.

Description:

Materials and Methods:

A two-stage sinus augmentation was carried out in six patients using mineralized solvent-dehydrated bone allograft (MCBA), freeze-dried mineralized bone allograft (FDBA), anor-ganic bovine bone (ABB), equine-derived bone (EB); synthetic micromacroporous biphasic calcium-phosphate block consisting of 70% beta-tricalcium phosphate and 30% hydroxyap-atite (HA-β-TCP 30/70), or bioapatite-collagen (BC).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	to perform biopsies from each six augmented site using to compare, histologically and histomorphometrically, the percentages of newly formed bone, residual grafted material, and marrow spaces.	After 6 months clinical and radiographic examinations were undertaken and each patient was reappointed for biopsy at the time of implant placement in the same location. Under local anesthesia, a full thickness flap was raised, a biopsy was performed using a 3.5 mm tre-phine bur under sterile saline solution irrigation, guided by the radiographic/surgical template in the selected implant site. A total of six bone samples was retrieved from the occlusal aspect to the alveolar crest, one from each augmented site to compare histologically and histomorphometrically the different materials.	6 month-healing after surgery
