When were acrylic resins first used in dentistry? |
1940's |
|
|
What does cross linking do to an acrylic resin? |
It improves the toughness of the material. |
|
|
Name three types of resin systems used in dentistry. |
Cold cure Heat activated Light activated |
|
|
Complete dentures are held in place by? |
Suction and saliva. |
|
|
Porcelain teeth in dentures are rarely used because they __________? |
Wear the opposing teeth. (Noisy) |
|
|
What is the first step in constructing a denture? |
A base plate and wax rims are constructed. |
|
|
What determines the patient's midline? |
The base plate and wax rims. (Nose) |
|
|
When the denture teeth are set in wax it is called the __________? |
"Denture set up" |
|
|
Partial dentures are supported by what? |
Natural teeth and alveolar ridge. |
|
|
What part of the partial denture goes around the abutment teeth? |
The clasps. |
|
|
How can the fit of an old denture be improved? |
Religning |
|
|
What is an immediate denture? |
It is placed in the same appt. as extractions. |
|
|
How can a dental hygienist help keep a denture clean? |
Remove the calculus from it. |
|
|
The term used when the denture teeth are set in wax is? |
Denture setup |
|
|
To repair a broken denture, a thin layer is ground off. Next, monomer is applied to the surfaces so that: |
Some of the set material is dissolved. |
|
|
Heat-activated acrylic resins systems are very similar to chemically activated systems. The major difference (or exception) is: |
No chemical activator is present in the liquid of heat-activated systems. |
|
|
True or False
Most denture teeth used today are acrylic rather than porcelain. Porcelain teeth are softer than acrylic teeth and do not cause excessive wear on natural opposing teeth. |
The first statement is true; the second statement is false. |
|
|
Partial denture frameworks usually include? |
Clasps, connectors, and mesh. |
|
|
Cross-linking of acrylic resins will improve the mechanical properties. The most important or beneficial property it would improve would be? |
Toughness. |
|
|
True or False
Mandibular dentures are easier to wear than maxillary. Saliva helps to improve the suction needed to hold a denture in place. |
The first statement is false; the second statement is true. |
|
|
The wax rims used for denture construction serve to determine the patients? |
Midline Plane of occlusion Size of denture teeth |
|
|
The acrylic resin of a partial denture is processed the same way as a complete denture, EXCEPT? |
The acrylic resin must flow through and around the mesh of the framework. |
