- All metal Eg. metal cast crown
- All porcelain (ceramic) Eg. Porcelain jacket crown
- A metal-ceramic combination Eg veneer
- A metal with processed resin Eg veneered crown
What does a partial veneer crown cover?
Restores only a portion of the clinical crown
Types of partial veneer crowns?
- three-quarter crowns
- reverse three-quarter crowns
- seven eighths crowns
- one half (1/2) crown veneers
- pinledge retainer
- laminates
- resin bonded restoration
- inlay retainer
- onlay retainer
What does Three quarter crown restore?
- occ surface
- all other surfaces except facial surface
What does the Reverse Three-Quarter Crowns restore?
Restore all surface except the lingual surface
What does Seven-Eighths Crowns restore?
Are extensions of the three-quarter crown to include a major portion
of the facial surface
EXCEPT MB cusp of max molars
What does one half (1/2) crown veneers restore?
Restores:
Occ surface
M surface
Portions of facial and lingual surfaces
All surfaces except D
Info on Pinledge Retainer?
- Restoration on ant three-quarter crown
- to obtain primary retention + resistance from long parallel pins in the lingual or palatal surface of the clinical crown
Pins and ledges of pinledge retainer?
3 pins and 2 ledges
Laminates✨
- R veneer restorations that restore the facial/labial surface
- fabricated from resin or dental porcelain + bond to etched enamel w/ composite resin luting agent.
Resin-bonded Restorations🫧
- r cast metal partial veneers that bond to etched enamel.
- r used as retainers for a fixed partial dentures (FPD).
- commonly referred to as a Maryland bridge.
Inlay Retainer 🦷
- is an intracoronal cast restoration
- that restores proximal + occlusal surfaces
- does not protect or cover the cusps
Onlay Retainer 💉
Deals w/ cusp damage on occ surface
Components of post crown system
- post
- core
- crown or extra coronal restoration
define bridge:
- It is a fixed dental prosthesis
- which replaces + restores function + esthetic of one or more missing natural teeth
- and can’t be removed from the mouth by the patient.
- It is primarily supported by natural teeth or root.
list the components of a bridge:
- Abutment Tooth
- Retainer (Attachment), (Abutment Piece)
- Pontic
- Connector Joint
Abutment Tooth def:
Is the natural tooth which supports and retains the bridge at one or both terminals.
define Pier (Intermediate Abutment tooth)
Is an isolated abutment tooth where the anterior and posterior adjacent teeth to it are missing.
Define Retainer (Attachment), (Abutment Piece):
Is a restoration rebuilding the prepared tooth and by means of which the pontics are anchored to the abutment teeth.
