Laboratory Materials And Procedures
Chapter 47
Anatomic portion - correct answer ✔The structural portion of a dental model
created from the alginate impression
Articulator - correct answer ✔Dental laboratory device that simulated
mandibular and temporomandibular joint movement when models of the
dental arches are attached to it
Crystallizations - correct answer ✔Chemical processes in which crystals
form a structure
Die - correct answer ✔An accurate replica of the prepared portion of a tooth
used in the laboratory during the fabrication of a cast registration
Dihydrate - correct answer ✔Related to gypsum products and indicating two
parts of water to one part of calcium sulfate
Dimensionally stable - correct answer ✔Resistant to changes in width,
height, and length
Face bow - correct answer ✔Portion of the articulator used to measure the
upper teeth as compared with the mandibular joint
Gypsum - correct answer ✔Mineral used in the formation of plaster is Paris
and Stone
, Hemihydrate - correct answer ✔Removal of water to become one half part
water to one part of calcium sulfate, forming the powder product of gypsum
Homogeneous - correct answer ✔Having a uniform quality and consistency
throughout
Lathe - correct answer ✔Machine used for cutting or polishing dental
appliances
Model - correct answer ✔Replica of the maxillary and mandibular arches
made from an impression
Monomer - correct answer ✔A molecule that when combined with other
molecules, for a polymer
Polymer - correct answer ✔Compound of ma y molecules
Slurry - correct answer ✔Mixture or gypsum and water used in the finishing
of models
Volatile - correct answer ✔Substance that can evaporate easily and is very
explosive
Where it should be the laboratory localized? - correct answer ✔In a separate
area away from the patient treatment area
What is the used of a laboratory in the dental offices? - correct answer
✔Pour up preliminary impression
Trim and finish diagnostic models
