Q

What are the 5 ways to determine width of anterior teeth?

A
  • Measure the width of the central incisor on existing denture
  • 1/16 the bizygomatic width equals the width of the central incisor
  • Bizygomatic width divided by 3.3 equals the combined width of the 6 anteriors on a flat plane
  • Corners of the mouth marked on the wax rim equals the combined width of 6 anteriors on a curved plane
  • Use the Interalar Facial Meter
