This type of restoration is applied directly to the tooth in a single visit.
Direct Restoration
What is the purpose of a matrix system?
Provides a temporary wall for the placement of restorative materials
The replacement of missing teeth with cast prostheses that are permanently cemented in place. EX: Crown and Bridge
Fixed Prosthodontics
A temporary crown or bridge that protects the tooth while the final prosthesis is being fabricated.
Provisional Coverage
What are the components of a fixed bridge?
Pontic and Abutment
BONUS POINTS*** Tell me what they are
This type of restoration is fabricated outside of the mouth and requires multiple visits
Indirect Restoration
What are the components of a universal Tofflemire?
Retainer frame, spindle, vise, and matrix band
What are some indications for fixed prosthodontic appliances?
One or two adjacent teeth are missing in the same arch, supportive tissues are healthy, suitable abutment teeth are present, the patient is motivated and able to maintain good oral hygiene.
Indications for a provisional crown
Protects the pulp, maintains periodontal health, provides occlusal stability, maintains tooth position, and protects the margins from fracture.
Use of proper ventilation, amalgam separators, and disposable procedures to avoid mercury exposure
Safety protocols for dental amalgam
Name two types of direct restorative materials
Composite and Amalgam
BONUS POINTS: Give me post op instructions for both.
What are the two types of matrix bands?
Universal and Extension
BONUS POINTS*** Tell me the difference
Restoration that covers only the occlusal and proximal surfaces (Fixed Prostheses)
Inlay
In a crown prep procedure, do you take your initial impression before or after the doctor preps the tooth?
BEFORE!!!!
Used when interproximal decay extends onto the buccal surface to allow proper positioning from the lingual side.
Contra-Angle retainer
What is Amalgam?

What is the difference between a sectional and universal matrix system?
Sectional: used for posterior composite restorations and offers tight anatomic contact
Universal: Used with amalgam restorations
Restoration that covers the occlusal surfaces and includes one or more cusps. (Fixed Prostheses)
Onlay
Crowns that are shell-like, made from polycarbonate material.
Preformed polycarbonate crowns
Materials used in indirect restorations
Gold, Porcelain, and composite resin
These are the steps for Composite Resin
Etch, bond, layering of restorative material, light curing, shaping, and polishing

Holds the matrix band against the gingival margin, ensures proper contour, prevents overhang.
A metal crown with a porcelain exterior offers both strength and aesthetics.
PFM crown
Crowns made specifically for the patient, offering the best fit and esthetics but time-consuming.
Custom provisional
Occlusal errors, locking on, marginal discrepancies
Complications with provisional crowns
