Anterior Restoration in Primary Teeth Flashcards
What are some treatment options for anterior teeth?
- intracoronal restorations (fillings)
- extracoronal or full-coverage restorations (crowns)
- extraction
- defer
Should you perform the following intracoronal restorations?
A. Class V
B. Class III
C. Class IV
A - yes
B - good luck
C - no thanks!
Describe the prep and materials used with a Class V prep on primary teeth.
prep
-similar to permanent teeth
-remove caries and extend beyond any decalcifications
materials
-esthetic materials (GI, RMGI, composite)
-do not use amalgam on primary anteriors
Why are Class III preps difficult to perform on primary teeth?
small crown
large pulp chamber
pulp horns close to the surface
If you keep the prep conservative to avoid the pulp exposure means you may not have the surface area for good bonding
What type of restoration is also known as ‘scoop and fill’?
interim therapeutic restorations (ITR)
What are some indications for ITR?
- very young (pharm contraindications)
- uncooperative or lacking ability to cooperate
- traditional prep and restoration not feasible
- caries control
- used in posterior also
The clinical success of ITR is with a ___ surface or small __-surface lesions.
single; 2
When are extracoronal or full-coverage restorations indicated?
-caries on multiple surfaces
-incisal edge involved
-pulp therapy indicated
-small cavitated lesion but extensive cervical decalcification or poor oral hygiene
-large single surface lesions
behavior makes precision difficult
What should the prep be for a strip crown?
- incisal reduction = 1-1.5mm
- interproximal reduction = 0.5-1mm BREAK CONTACT
- facial reduction = 1mm
- lingual reduction = 0.5mm
- All margins are FEATHER EDGE
When you select crown forms, what should you look for?
alignment and rotation
What are the steps to strip crowning?
- Occlusal radiograph
- pre-op
- prep
- select crown
- gingival retraction and hemostasis
- rinse retraction paste, then etch
- rinse etch, dry then bond
- fill crown form with composite but make room from the tooth
- seat crowns. remove excess composite before curing
- cure
- remove crown form with an instrument
T/F. With the Pedo Jacket and Life Like Crown, you fill with composite but the crown form is NOT removed.
True.
What preformed option is easiest to place, most durable, has a quick procedure, and can be crimped to fit?
SSC
obviously esthetic problem
___ SSCs have better esthetics, can be placed with poor moisture and hemorrhage control and some can be crimped on the lingual. But they are difficult to fit, have limited shades, the white facing can break off, and they are more expensive.
Preveneered
What preformed option must you make the tooth fit the crown?
preveneered SSCs because the crown can’t be forced on or facing will crack
