Post-Eruptive Tooth Movement Flashcards
1
Q
what 3 things must be accommodated for when a tooth is erupting?
A
- growth
- occlusal wear
- interproximal wear
2
Q
what may happen if the opposing tooth is absent
A
the tooth may over-erupt until the masticatory forces meet an equilibrium
3
Q
what is proximal drifting? aka mesial drift
A
the migration of tooth from its normal position in the dental arch
- posterior teeth move forward into gaps
4
Q
what forces drive mesial drifting?
A
multiple forces acting on teeth
- anterior component of occlusal force
- forced into socket and forwards
- pressure from cheek muscles and tongue
5
Q
why do teeth mesially drift?
A
suggested that there is contractibility within the tooth tissue transeptal fibres
