PURPOSE: To evaluate the histologic and histomorphometric data 10 years after grafting of maxillary sinus in a case using anorganic bovine bone matrix (ABBM) and plasma rich in growth factors (PRGF).
MATERIALS AND METHODS: Histomorphometric measures were performed for newly formed bone, ABBM particles remnants, marrow spaces, and the presence of osteoblastic and osteoclastic activity.
RESULTS: Histologic analysis showed ABBM particles surrounded by new compact and mature vital bone. Osteocytes were noted within lacunae. Some osteoblastic and osteoclastic activity could be identified. The histomorphometric results were 21.7% of newly formed bone, 33.9% of ABBM, and 44% was composed of marrow spaces.
CONCLUSIONS: After 10 years postoperatively, the histologic evaluation of this case report demonstrated slow replacement of the ABBM particles by newly formed bone, even with the addition of PRGF. The residual ABBM particles were found in close contact to the newly formed bone.
