COMPLETE SOLUTIONS
What type of material is used to make master (definitive) casts correct answer: Type III Stone
Which of these materials will set the fastest:
A. Alginate mixed with warm water
B. Microstone mixed with warm water
C. Alginate mixed with cold water
D. Microstone mixed with cold water correct answer: a. Alginate mixed with warm water
What is the purpose of using BOTH Accu-film (articulating paper) and shim stock for occlusal analysis? A. Because some people need to see their marks of where to check with shimstock
B. You don't - one is as good as the other
C. The darker the mark made with accufilm, the better the occlusion - so only check light spots with shimstock
D. Shimstock verifies the occlusal analysis markings made by accufilm to ensure they are not artifact marks. correct answer: D. Shimstock verifies the occlusal analysis markings made by accufilm to ensure they are not artifact marks.
Shim stock is a thin material used for: correct answer: Register occlusal contacts Which part of the facebow is used to point at 43 mm above the incisal edge of the patient's maxillary incsisors? correct answer: Anterior Reference Pointer
(T/F) Centric Relation (CR) is independent of tooth contact? correct answer: True
The CR record should contain impressions of cusp tips from which teeth correct answer: Posteriors of Mandibular and Maxillary teeth

above the central incisors
(T/F) The anterior reference point in an edentulous patient is measured from the lower border of the upper lip at rest. correct answer: True. Measured from the lip, not the gingiva!
What is main purpose(s) of occlusal analysis? correct answer: A. Identify initial contact
B. Identify occlusal wear
