Assignments
Reading 1: Read about opaqueing and be able to describe the process of deoxidizing metal ceramic frames and the chemical reaction between opaque and metal understructure. 
Reading 2: Read about opaque and be able to describe and define the three primary purposes of the opaque porcelain. 
Writing, problem solving, performance 1: Write a one-page essay describing how shade matching, color control and characterization are among the most vital aspects of ceramic restoration development. 
Writing, problem solving, performance 2: Write a one-page narrative on a current dental ceramic technique, material or alloy from the Trends and Techniques magazines available in the Diablo Valley College Library Dental Technology section. 
 
Evaluation
Sample One: Prepare porcelain frame designs and copings: (a) Metal finish copings to the appropriate thickness, (b) Degas non-precious alloys, (c) Stack and contour incisal and body porcelain, (d) Bake stacked porcelain in a porcelain furnace. 

Sample Two:

Answer the following questions: (a) Describe two methods of removing moisture from dental porcelain. (b) Describe the difference between natural glaze and artificial glaze, (c) Describe the opaquing process.

 

Frequency of Evaluation:

Evaluations will adhere to the DVC "Fairness in Grading" guidelines and will include as a minimum:

  • Evaluation of students within the first quarter of the course and notifying student of the results

  • Counting a final examination for no more than one-half the course grade

  • Basing final grades on at least three students' tests and/or reports
