1. To begin the process of injection mold, you need a minimum of:
 

a. Model of the existing teeth and the full smile design.
 

b. Model of the existing teeth and the every-other-tooth design.
 

c. Model of the every-other-tooth design and full smile design.
 

d. Model of the existing teeth, every-other-tooth design and full smile design.

 

2. In selecting the tray, you want to be sure it has the following:
 

a. With holes that are larger than your design.
 

b. Without holes that are larger than your design.
 

c. With holes that are as tight as possible to your design.
 

d. Without holes that are as tight as possible to your design.

 

3. All are important reasons for using a clear PVS material except:
 

a. Clear PVS material is more flexible than traditional impression materials.
 

b. It allows better visualization of flowable tip insertion.
 

c. It allows for the curing light to cure the material through matrix.
 

d. It allows the clinician to see when the tooth is filled all the way.

 

4. In selecting the best flowable for the injection mold technique, the most important attribute would be:
 

a. The flowable is not too viscous.

​

b. The flowable has small fillers throughout.
 

c. The flowable has large fillers throughout.
 

d. The flowable have high wear resistance and flexural strength.

 

5. During the first pass injections, you should:
 

a. Inject the every-other-tooth matrix and inject the teeth that are of the new design.
 

b. Inject the every-other-tooth matrix and inject the teeth that are of original teeth.
 

c. Inject the full smile design and inject every-other-tooth.

​

d. Inject the full smile design and inject the whole design.
