Resumen
To develop a new surgical model for sinus floor augmentation (SFA) in rabbit for experimental purposes. Materials and Methods: Eight adult rabbits were used, two for a surgical design using the anatomical dissection study, and the other six for an endoscopically assisted intraoral approach of SFA unilaterally, creating a subantral space where an allograft biomaterial was deposited. SFA was verified through cone-beam computerized tomography. Healing, weight, food, feces, and
behavior were evaluated for 4 weeks post operatively. Results: All animals survived. There was no bleeding or infection; inflammation was mild. No changes were observed in terms of feeding, weight, feces, or behavior. Tissue healing was normal. Conclusion: This model is a refinement of the experimental technique and is a real option for SFA, without compromising
animal morbidity because of its conservative design. The
minimally invasive approach with endoscopic assistance reduces bias and improves surgical predictability.
Sinus floor augmentation (SFA) is a useful technique for
treating severe sinus pneumatization before the placement of
dental implants. The singular anatomy and physiology of this
anatomical site, in addition to the clinical importance that it has acquired, makes it ideal for investigating biomaterials,
which has led to the proposal of various animal models including the rabbit (1-3).
