For my STEAM project I focused on teeth. The first photo shows the parts of the teeth, like nerves, blood vessels, enamel, dentin, etc. That model also shows the tooth joint with the bone. The last three photos show the different types of teeth, like incisors, canines, premolars, and molars. They are attached to the alveolar processes of both the maxilla (top bone) and mandible (lower jaw bone).
