Smile Design Flashcards
Contraindications for veneers:
- Active caries
- Active perio
- Active erosion and wear
- Lack of posterior occlusion
- When ortho is a better option
- When crowns would provide better contours
Indications for veneers:
- Deep internal staining
- Chipped teeth
- Slight to moderate crowding
- Spaces (peg lateral)
- Replacing previous veneers
What happens to the condyles when the molars are missing.
The mandible advances forward to find a position of maximal contact of remaining (anterior) teeth.
Forces placed on anterior teeth when posterior contact is missing.
COMPRESSIVE
Anterior teeth without molar occlusion will:
Break, wear, or flare
Eruption with loss of attachment.
Active eruption
When the periodontium and bone grow, causing supereruption. There’s no attachment loss.
Periodontal growth
Supereruption that’s more common in:
Females
Maxilla
Younger patients
Premolars
Periodontal growth
This type of supereruption is more common in:
- Older patients
- Mandibular teeth
Relative wear
Loss of posterior teeth can lead to this.
TMD
Tells you the age of the tooth.
Central
Tells you the gender of the person.
Lateral
Tells you the PERSONALITY of the person.
Canine
This says that as you go from midline to distally, each successive tooth should look proportionally smaller.
Golden Proportion
The golden proportion for anterior maxillary teeth.
1.618 –> 1.0 –> 0.618
The proximal contacts of the upper incisors should be what percent of the length of the CENTRAL?
50-40-30
The cervical part of the interproximal contact should not be more than how manny mm from alveolar crestal bone in order to avoid black triangles?
5
Older teeth have smaller _________.
embrasures
Length of anterior teeth in older patients.
Shorter (due to wear)
Length to width ratios of anterior teeth in older patients.
Shorter
Color/Chroma of teeth in older patients.
Higher
Embrasure size in older patients.
Smaller
2 ideal elements of an occlusion.
1) Only centrals contact in protrusion
2) Only posteriors contact on the working side in lateral protrusion
Ideal gingival zenith for anteriors.
Centrals and canines are equal, and laterals are lower.
