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 |
