Chapter 9 Flashcards
used to isolate area of restoration
dental dam or rubber dam
prevent saliva from obstructing the procedure, protection against caustic materials, swallowing small objects, and injury to adjacent structures
Barrier
the tooth requiring treatment can be isolated from the remaining dentition, allowing it to better visualized
isolation
removal of the carious lesion
debridement
cutting the tooth to accommodate and hold the restorative material, and assuring that once restored, the tooth will withstand use
Preparation form
any impurities are removed and the tooth surfaces are cleaned
refine
is a “molding” device that surrounds the tooth to ensure the tooth wall maintains its original shape
matrix
maintaining the original tooth shape and contour, and ensuring that gingival space is not obstructed
embrasure
metal retaining device that is fitted and tightened around the tooth
Tofflemire matrix
round band with locking ends that are tightened and locked into place
AutoMatrix
cone-shaped steel rings with “wings” to retain its shape and hold
T-strip
metal strip acts to “replace” the tooth wall and is kept in position by the retainer
Sectional matrix and ivory retainer
strip is used for anterior restorations and is manually kept in place
Mylar strip
produces a lining against stress force, heat, and jolts
Insulation
encourages dentin growth
Palliation
temporary shield between treatment visits
Protection
usually used as a temporary measure to fasten the base material to the restorative material, between treatment visits
Luting
permanent attachment of restorative material to the prepared tooth
Cementation
thin layering of sub-material to the prepared tooth
Lamination
prevents leakage under restorations by sealing the cut edges of the prepared tooth
Varnish
liquid coating that produces a barrier against chemical irritation
Liner
acid solution that scratches/carves microspaces
Acid etchant
allows restorative agent to unite or “fuse” to the tooth surface
Bonding agent
barrier against heat and chemical irritation
Base
to retain metal posts and pins in deep tooth preparations
Cement
basic handling techniques (different products require different methods)
Manipulation
some products require a uniform blended mixture
Homogenous
preparing for an amalgam restoration by mixing the mercury and the metal alloy in a mechanical device.
Amalgamation or trituration
triturated mass is “kneaded” as a final step in amalgam mixing
Mulling
spreading the materials out, to be mixed in a larger area
Dissipate
a curing process that adds a compound to a movable/liquid material, to transform it into a solid form
Polymerization
scratching/etching tooth surfaces to leave microspaces to which the material bonds, or “locks” into
Bonding
various metals and liquid mercury blended into a soft form that hardens
Amalgam
non-metallic material mixed into a plastic mass that sets
Cement
hardened resin material available in several forms
Composite
white porcelain material often used on tooth facial surfaces
Veneer
ultra-thin sheets of pure gold
Gold foil
small amounts of material are added at one time
Increment
packing the material into the prepared tooth using force that prevents unmissed void areas
Condensation
smoothing the restorative material toward the margins
Burnish
coloured paper to bite down on, to assess occlusal surface contacts
Articulating paper
porcelain bond applied to the front surface of anterior tooth for permanency and to improve appearance
Laminate
