Introduction: The main artery that supplies the mucoperiosteum of the hard palate is the greater palatine artery. The knowledge detailed of the vascular anatomy of the palate and, in special, of the region of the greater palatine foramen is important for prevention of lesions vascular during procedures in this region. Among these procedures, it included the making of shreds for correction of failures in the hard palate, soft palate and cranial base. Objective: To develop an anatomical model that can illustrate the endoscopic anatomy of the greater palatine foramen and analyze the technical of injection intra vascular of colored silicone is sufficient for fill the lower arterial branches than irrigate the hard palate. Method: The form of study was experimental through the endoscopic dissection of 10 greater palatine arteries in five heads of corpses prepared with injection intra vascular of colored silicone. Results: Of the total of 10 arteries dissected, 8 properly were colored by the technique of injection employed. What corresponds to an efficacy of 80%. Conclusion: The anatomical model showed to be a feasible approach for the endoscopic study of the greater palatine foramen, being the injection of efficient silicone in the terminals vessels coloring in 80% of the cases.
