E95SHP-UCO.19 – The maxillary model has the sinus along with tooth #8, 12 and 14 that consist of a bi-layer material to simulate the hard enamel and soft dentin. The #8, 12 and 14 are also anatomically rooted, radiopaque and have the canals in place. This allows you to practice endodontic procedures on the teeth and then see if the teeth were over filled and also the ability to take radiographs. Below the teeth (on every tip) there is a silicone lesion. The gum can be refracted and surgery can be performed. The lesions can be removed and the gingiva can be sutured back into place.
