Denture teeth: upper anterior teeth height?
distance from lower edge of occlusion rim
to smile line: height of central incisors
Denture teeth: upper anterior teeth width?
Canine line: total distance between canines
Denture teeth: lower anterior teeth height?
distance from lower edge of upper occlusion rim to lower record base.
Denture teeth: lower anterior teeth width?
4mm more than manufacturer’s recomendations
Denture teeth: upper posterior teeth height?
If porcelain teeth are selected, they must have a low profile (so underside is not cut)
Denture teeth: upper posterior teeth width?
From distal surface of canine to end of occlusal plane
Denture teeth: lower posterior teeth height?
distance from occlusal plane to record base
Denture teeth: lower posterior teeth width?
2 mm more than upper teeth

over residual ridge
Denture teeth arrangement steps? (12)
- Remove lower occlusion rim
- Draw retromolar trigone over lower cast
- Attach truwax to upper rim
- fix occlusal plane to lower record with wax
- draw midline
- draw upper front teeth incisal line
- remove upper rim
- mark mniddle of retromolar trigone
- Draw line from distal of canine to middle of retromolar trigone
- put upper record base in
- ass soft wax roll to upper record
- arrange upper central first then rest of teeth
After the teeth are arranged in the rim what do we do? (7)
- preform a 2mm protrusive movement in articulator
- arrange lower front teeth
- Get the articulator back in centric relation
- arrange lower first molars
- Continue towards midline
- small adjustments and 3mm protrusion
- 3mm lateral movement
Denture teeth: Objective of waxing? (4)
- Improve grip over denture teeth.
- Esthetics of soft tissues.
- Reshape teeth.
- Improve fit and border seal of denture base
