This document discusses factors that control the arrangement of artificial teeth in complete dentures. The four main factors are the horizontal and vertical positions of the teeth, esthetic requirements, and inclinations for occlusion. It describes anatomical landmarks that guide the placement of teeth, such as the retromolar fossae and papilla in the mandible. Correct vertical positioning provides denture stability, favorable forces, lip and cheek support, and compatibility. The arrangement is also influenced by age, sex, personality, and cosmetic preferences to provide a natural appearance.
