abstract = {Aim: To compare the effectiveness of two xenografts for maxillary sinus floor augmentation
in terms of clinical, radiographical, histologic, and molecular outcomes.
Materials and methods: A split-mouth
randomized clinical trial was conducted at the
University of Granada. Ten consecutive patients in need of bilateral two-staged
maxillary
sinus floor augmentation were included. Each patient received both biomaterials
(porcine bone mineral and anorganic bovine bone), which were randomly assigned
for bilateral sinus augmentation. The maxillary autogenous bone scraped from the
sinus access window was mixed with each xenograft at a 20:80 ratio. After a healing
period of 6 months, bone biopsies were collected with a trephine during the implant
placement in the regenerated area. Histologic, histomorphometrical, immunohistochemical,
and molecular outcomes were analyzed. Clinical and radiographical data
throughout the treatment phases were also evaluated.
Results: The resulting anatomic features were similar between both groups. After six
months of graft consolidation, the graft resorption rates were similar between both
biomaterials. The histologic, histomorphometrical, and immunohistochemical results
showed no statistical differences between groups.
Conclusion: Anorganic bovine bone and porcine bone mineral combined with maxillary
autogenous cortical bone show similar biologic and radiologic features in terms of
biomaterial resorption, osteoconduction, and osteogenesis when used for maxillary
sinus floor augmentation.},
