This model manufactured by Nacional Ossos is a cross-section of the skull, manufactured with mechanical properties similar to human bone (type 2). The maxilla, with gingiva and maxillary sinus with flexible membrane, TMJ, zygomatic, auricular and occipital, has teeth 18 and 28 included. Tooth 13 is included in the palate and tooth 23 is included in the buccal. The mandible also covered with material that simulates soft tissue, has teeth 38 and 48 included. (All impacted teeth are encapsulated and radiopaque.) The support allows you to make all the necessary movements of opening the mouth, tipping and closing for the student to work with both hands as in the real patient, being ideal for studies, surgical practices and workshops, and can be cut and perforated. This practical and didactic model allows the professional who uses it to have training very close to the real thing, improving techniques with respect to Bioethics.
