4. PROVISIONALS
PREPARATIONS THAT INVOLVE THE REMOVAL OF CUSP TIPS OR EXTEND OVER A CUSP TIP ON THE FACIAL OR LINGUAL SURFACE THE RESTORATION NEEDS A EXTRACORONAL TEMPORARY.
Inlay Onlay
Short-Term
Dentin Primer
Reduce sensitivity
Coat entire prep
Glass Ionomer
Pulpal floor
Custom acrylic Resin temp
Place in prep –patient bite down (intercuspation)
Non retentive design
Polycarboxylate cement
Eugenol cement (tempbond)
CAN/CAM – CEREC same day

5. CRITERIA Comfortable and esthetically acceptable
Stable with mesial and distal contacts
Occlusal alignment
Easily removed without damage to prep
Fits snug and accurately along prepared margins (>.5mm from finish line/margin)
Original tooth contours
Protect gingiva from irritation and food impaction

6. Preformed Aluminum Crowns
Different sizes and anatomical features
Lack esthetic value
Without anatomy- resemble thimbles- parallel
Contouring necessary to adapt to tooth
Fill with acrylic or composite- custom fit
Preformed Acrylic Crowns
Different sizes, shape and shades
More esthetically pleasing for anterior
Shape and contour of tooth
Tabs on incisal- ease of placement- remove prior to cementation
Fill with acrylic then trimmed before cementation
Custom Acrylic/ Resin Crowns
Accurate anatomical features
Proximal contacts
Proper occlusion
Food deflection
Marginal contours
Matrix
Direct- alginate, block,wax or thermo plastic buttons
Indirect- matrix on model, wax or vacuumed formed shell
Self-cure
Methyl Methacrylate R’Methacrylate (resin)
Physical properties
Esthetics color stability
Strong odor
High shrinkage (R’ less)
High exothermic heat during curing (R’ slightly lower)
Composite
Excellent color stability
Two pastes
Trim with diamond bur
Remove greasy inner coating
Use folwable to add to margins or repair
