Chapter 34 Dantal Dam/Tofflemire & Amalgam/Composite
Term | Definition |
---|---|
Matrix Band | Wraps around tooth and held by Tofflemire to secure tooth; works as artificial wall during restoration |
Clear Plastic Matrix | Used on composite restorations; works with Tofflemire and wraps around tooth to secure mesial and distal walls |
Vise | Holds ends of matrix in place diagonal slots of Tofflemire |
Spindle | Screw like rod that secures band in vise in Tofflemire; by turning the outer knob |
Outer Knob | Tightens and loosens spindle against band in vise; makes band tight in Tofflemire |
Tofflemire Retainer | For posterior restorations (class II); creates artificial wall around tooth |
Jaw | Part of clamp that expands to fit over tooth then released to securely fit on 1/3 of tooth |
Bow | The arch part of the clamp |
Overhang | Excess material left behind interproximal after restoration |
Wedges | Small triangular pieces of wood or plastic. Inserted interproximal during restorations to secure Tofflemire band |
Class II Cavity | Posterior proximal and occlusal |
Class I Cavity | Pits and Fissures |
Class III Cavity | Interproximal on anterior |
Class IV Cavity | Interproximal anterior and incisal edge |
Class V Cavity | Cervical 1/3; at gum line |
Ligature | Placing floss or cord to secure stabilized dental dam |
Inversion | Tucking edges of dental dam around tooth; stops leaking around gingival margin |
Winged Clamps vs Wingless Clamps | Winged - have extra projection for better retraction; angled towards gingival Wingless - no projections and have "W" on clamp |
Punch Plate | Part of working end on the dental dam punch; the dial turns for different sized holes to punch |
Septum | Dental Dam material that slides between teeth |
Key Punch Hole | 1st and largest hole punched; this hole slides over clamp and over anchor tooth |
Anchor tooth | Tooth that clamp is placed on |
Circumference | Area around; Edge that faces towards gingival. Larger circumference edge faces towards occlusal |
Stylus | Pointy sharp projection on Dental Dam Punch that punches hole |
