Q

There are 3 classifications of medical/dental devices grouped according to the amount of control needed to ensure their safety and efficacy

A

Class I: lowest risk; ex. Gloves, prophy paste, OTC PRODUCTS

Class II: products required to meet performance standards set by FDA or ADA. EX. Amalgam, composite

Class III: most regulated devices which sustain or support human life- require FDA approval. Ex. Bone grafting material, implants

Q

What is the most widely used impression material

A

Alginate hydrocolloid

22
Q

Alginate hydrocolloid changes from

A

Sol phase to a gel phase via chemical reaction and it cannot be reversed

23
Q

Alginate hydrocolloid is not accurate enough for final impressions, why?

A

Does not capture fine detail
Does not flow well into embrasures or occlusal surfaces

24
Q

Alginate is

A

Elastic irreversible impression material made from seaweed

25
Advantages of irreversible hydrocolloid
Good for Subgingival impression Working in a “wet” environment Pouring models
26
Disadvantages of irreversible hydrocolloids
Shrinkage (syneresis) Swelling (imbibition) Poor tear strength Client care- burning “tissues”
27
Using incorrect tray size when taking an impression will result
In an unacceptable impression
28
What may be used to extend the tray
Utility wax
29
Custom trays allow for
A more comfortable fit allowing for more accurate impressions
30
Triple trays allow clinician to take an impression of
Max mand and bite reg at the same time
31
Elastomeric materials are used (2)
-Where teeth are present and material flexibility is needed for removal from the oral cavity or teeth - for impressions of preparations and for demanding highly accurate reproductions
32
Elastomeric materials have qualities similar to? Composed of ? Do they have different viscosities?
Have qualities similar to rubber Composed of a base and an accelerator Have different viscosities (putty, heavy, light bodied)
33
What is polysulfide
Oldest of the elastomers known as mercaptan rubber or rubber base
34
Polysulfide has an unpleasant
Taste, odor and stains clothing
35
Silicone material is available as
Additional reaction and condensation reaction
36
What should not be mixed with latex gloves on
Silicone putty
37
What is added to condensation silicone as a filler to keep the silicone paste from being runny and to provide stiffness
Silica or copper carbonate
38
What is the stiffest of all elastomers
Polyether
39
Most common method of displacing the gingival tissue away from the tooth prep to create space for impression material
Gingival retraction cord
40
Bleeding when using a retraction cord can be controlled by using (3)
LA with epinephrine Astringent Coagulation with laser or electrocautery
41
Advantages of digital impressions
No need for impression trays or materials Images can be magnified, reviewed and retaken More accurate
42
Disadvantages of digital impressions
Cost Training/practice Lab fees Size of scanner
43
What does chroma refer to
Intensity or strength of the colour *teeth are generally pale in colour
44
Value refers to
How light or dark the colour is; teeth have value ranges in light scale; they are determined by the way they reflect light
45
What does metamerism refer to
Colours look different under different light source
46
Bridge: what does retainer refer to
Part of bridge that fits over abutment
47
What is a Pontic
False or artificial tooth
48
What is abutment
Supporting natural tooth
49
Does an inlay involve cusp tips
No
50
What cavitron tip is the latest addition to the cavitron inserts designed for plaque and calculus removal around titanium implants and abutments
Cavitron softip ultrasonic implant insert
51
The cavitron softip implant insert is only used with a
Softip disposable prophy tip attached (single use item)
