Occlusal
Chewing surface of posterior teeth
Lingual
The inside or “tongue” surface of all teeth
Buccal
Outside surfaces of posterior teeth
Distal
The surface of the tooth that is away from the the median line
Mesial
The surface of the tooth that is toward the median line
Median Line
An imaginary line between two central incisors
Proximal
The surface of a tooth adjoining another tooth
Cusps
Tapering projections on the crown of a tooth
Sulcus
A depression in the occlusal surface of a tooth
Incisal
The biting edge of anterior teeth
Operative Dentistry (objective)
To restore the functional and esthetic viability of the teeth
Step 1 of Operative Dentistry
Removal of decay or old restorations. Completed as “direct” proceedures
Step 2 of Operative Dentistry
Prep the site
Step 3 of Operative Dentistry
Restore the tooth using materials such as amalgam or composite
Step 4 of Operative Dentistry
Polish the restorative material

Name 6 Types of Crown & Bridge Prep Designs
Chamfer, Curettage, Shoulder, Modified Shoulder, Beveled Margin, Feather
Chamfer Preparation
A type of crown & bridge prep design that involves a rounded gingival margin. Uses a Round End Taper. Popular for PFM and some ceramic restorations
850 shape is used for anteriors
856 shape is used for posteriors
Chamfer Preparation sizes
Curettage Preparation
Rounded margin with 60’ finish line. Popular for PFM restorations. Also known as Modified Chamfer
877k & 878k shapes used for this
Curettage or Modified Chamfer sizes. The K is german for Kurettage.
Shoulder Preparation
90’ gingival finish line with square internal angle. Popular for all ceramic restorations.
836 & 837 shape is parallel
846, 847, 848 is taper design
Shoulder Preparation sizes
Modified Shoulder Preparation
90’ gingival finish line with rounded internal angle. Popular for CAD/CAM restoration
847KR
Modified Shoulder preparation size
Beveled Margin Preparation
Parallel axial wall and 45’ gingival finish line. Popular for full cast crowns. Not as prevalent due to the increase in price of gold.
878 & 885
Beveled Margin Preparation sizes
Feather Preparation
Tapered axial wall with an extended chamfer finish line. Popular for full cast crowns and pedo stainless steel crowns
862, 863, 864
Feather preparation sizes
2 Types of Direct Restoration
Composite & Amalgam
2 Types of Indirect Restoration
Fixed Prosthetics (i.e. crowns) & Removable Prosthetics (i.e. dentures)
Direct Restorative Procedures
Done in the dental office only. Mainly fillings.
Indirect Restorative Procedures
Involves dental lab. Includes treatments such as Crowns, Veneers, Onlays, Inlays, Fixed Bridges, Partial and Complete Dentures
Direct Restorative Materials
Direct gold, silver amalgam, composites, glass ionomers, compomers
Indirect Restorative Procedures (objective)
The rehabilitation of oral function and esthetics by restoring or replacing missing teeth with synthetic replacements.
5 Types of Indirect Restorations
Crowns, Bridges, Veneers, Inlays, Onlays
Indirect Restorative Materials
Cast alloys, PFM, ceramics, lab processed composites, acrylics
5 Steps of Indirect Restoration
- Removal of existing restoration or decay
- Prep the tooth. Bulk reduction of dentin and enamal.
- Finish the margins
- Restore the tooth using porcelein, PFM, Zircona, etc
- Polish the restoration and make bite adjustments
2 types of crown materials
PFM and Zirconia
Onlay
Similar to a crown, but more conservative. It will replace one or more cusps but not cover the entire occlusal surface
Inlay
A type of indirect restoration that restores the occlusal surface between the cusps
4 Uses of Diamonds
Bulk reduction of dental or enamel
Bracket removal
Contouring and finishing prep, margin, & dental materials.
Crown removal (porcelain material only)
3 fun facts of diamonds
- Axis carries over 700 shapes & sizes
