Study Notes
Cavity Classifications Using Posterior Matrix Systems
- Class II, III, and V cavities in posterior teeth
Plural of Matrix
- Matrices
Posterior Matrix Band Retention
- A "wedge" is used to hold a posterior matrix band in position intraorally.
Matrix Band Placement
- The smaller circumference of the band is placed gingivally.
Instrument for Matrix Band Contouring
- A contouring instrument is used to contour the matrix band.
Tofflemire Matrix System
- A wedge is used in the Tofflemire matrix system to reestablish proper contact with the adjacent tooth.
- The Tofflemire matrix retainer is tightened securely within the band loop.
Wedge Placement
- Improper wedge placement can cause open contacts or overcontoured restorations.
Clear Plastic Matrix
- Another term for a clear pastic matrix is mylar.
Tofflemire Alternative
- The universal matrix system is an alternative to the Tofflemire retainer.
Thin, Coated Matrix Band
- Another term for a thin, coated, nonstick matrix band used for posterior composites or amalgam restorations is a "clear" matrix.
Wedge Placement
- A wedge is most commonly placed from the buccal side into the interproximal space.
Tofflemire Retainer Placement
- The slotted surface of a Tofflemire retainer is always positioned facially.
Celluloid Band Placement
- A celluloid band is placed during an anterior composite resin restoration before placement of the initial composite resin increment.
Best Matrix System for Primary Teeth
- The universal matrix system, or other "clear" matrix systems are generally considered the best for primary teeth.
