Flashcards
Central incisor width estimation
Central incisor width estimation
The width of the central incisor is estimated as approximately 1/16th of the distance between the two cheekbones (zygomatic arches).
Lip lines and anterior tooth length
Lip lines and anterior tooth length
The height and position of the lip lines, particularly the high lip line, play a crucial role in determining the ideal length of the front teeth (anterior teeth).
Nose-canine alignment
Nose-canine alignment
A vertical line drawn from the side of the nose, specifically the wing (ala), should ideally pass through the middle of the upper canine tooth for balanced facial aesthetics.
