Incisors: designed for cutting central and lateral (front teeth) Cuspids: canine/eye teeth, designed for tearing bicuspids- 2 points/cusps o. Molars: designed for grinding and pulverizing (1st, 2nd, 3rd/wisdom) Enamel: hardest tissue in body to resist abrasion. Pulp: the heart of the tooth, contains the nerve. Cementum: thin layer of bone, holds tooth in place. Buccal or labial surface (next to the cheek) Occlusive surface (where the top tooth fits in to the bottom tooth) Open bite: front teeth don"t occlude excessive posterior dental eruption. Class one: 1st manudbular retracted distance of 1/2 re: 1st maxillary molar. Class two: maloccultion- most common (1st mandibular retracted 1 + re:1st maxillary molar)
