Maxillary sinus lift with a collagenic equine heterologous bone substitute. Histomorphometric analysis
Objectives: In this article, the authors describe their use of a heterologous equine collagen bone substitute for a maxillary sinus lift, and they assess the efficacy of this biomaterial when utilized with autologous bone
Materials and methods: Maxillary sinus lift is a common surgical procedure in dentistry practices. A wide array of biomaterials and bone substitutes are available for this purpose. Their efficacy varies in terms of the amount of de novo bone production observed at a given point in time. Nonetheless, histomorphometric analyses are not usually performed during routine clinical practice. The authors performed a sinus lift procedure in a 66-year-old male with the aid of an equine collagen graft. Eight months later, at the time of implant placement, two biopsies were collected for the histomorphometric analysis.
Results and conclusions: The histomorphometric analysis revealed spongy bone tissue undergoing remodeling, and 42% of the tissue was newly formed bone. There was no evidence of an inflammatory reaction.
