Portraying the lower jaw of an eleven year old magnified 3.5X natural size - making observation effortless - this unbreakable vinyl model dramatizes progressive stages in tooth succession.
Four teeth, each typifying a distinct tooth type, are individually extractable - a rear plus for hands on investigations
Other highlights include: cutaway jaw bone exposing roots of teeth, and the nerves and blood vessels which supply them - delineated in contrasting colors. Developing permanent teeth - even a wisdom tooth (3rd molar) - still embedded in the jaw, below the gum line, one molar sectioned lengthwise, from crown to root revealing its internal arrangement of enamel, dentin, and pulp.
21 pertinent features, hand numbered on the model, are identified and fully defined in the accompanying 4 page study guide.
Overall dimensions: 14" x 5" x 9" (36cm x 13cm x 23cm)
