Adult Orthodontics Flashcards
Why do adults sometimes seek orthodontics?
- improve aesthetics
- relapse of malocclusion
- facilitate restorative treatment
- after periodontal drift
How does adult orthodontics differ from in children?
- lack of growth in adults (no growth modification)
- perio disease risk
- missing/heavily restored teeth
- physiological factors
- adult motivation
Can skeletal discrepancy be altered in adults easily?
NO
- surgery required
What is essential that the dentist does before committing to adult orthodontics?
PERIODONTAL ASSESSMENT
- no active periodontal disease allowed
- perio disease leads to lack of support
What does periodontal disease lead to in adult orthodontics?
Loss of support:
- tooth centre of rotation moving apically
- anchorage value reduces
Why might heavily restored teeth be a problem in adult ortho treatment?
can complicate bonding
What physiological factors complicate orthodontics in adults?
- decreased cell turnover, initial movement can be slower
- use lighter forces
Why might orthodontics be required as an adjunctive to restorative work in adults?
- upright abutment teeth to aid restoration
- intrusion of over-erupted teeth
- extrusion to increase crown length
Why might adults need orthodontics after periodontal disease?
- tooth spacing after perio disease
- increased overbite
- proclined incisors
What are Andrews Six Keys of orthodontics?
- Tight appoximal contacts with no rotations
- Class I incisors
- Class I molars
- Flat occlusal plane or slight curve of Spee
- Long axis of the teeth have a slight mesial inclination except the lower incisors
- The crowns of the canines back to the molars have a lingual inclination
