We present a prospective randomized experimental study comparing bone regeneration obtained in 60 post-traumatic frontal sinuses obliterated with either calvarial bone dust (n = 30, group I) or calvarial bone and demineralized bone matrix (DBM; n = 30, group II). Radiological follow-up included high-resolution computed tomography with quantitative micro-density analysis in Hounsfield units (HU), together with a volumetric evaluation of the ossification at 6 and 24 months after surgical treatment. Epidemiological information and potential drawbacks were analysed. Bone volume and density data (HU) for the regenerated areas were subjected to statistical analysis at 6 and 24 months for both groups. Results were compared with reference values obtained from frontal and temporal bone in every patient. Complications developed for 10% of operated sinuses. The resulting bone formation (HU) in group I patients was significantly better than that obtained in group II. Ossification progressed in a statistically significant manner in both groups when compared at 6 and 24 months postoperatively. The use of DBM as a biomaterial associated with calvarial bone dust for sinus obliteration shows long-term safe results, similar to autogenous bone, but with a lower final bone density.
