On a partial denture case similar to the scenario that you have on the typodont with the 5 remaining teeth, which statement best describes the patient's plan of occlusion?
a) the ala trogus line b) The frankfort plane c) anterior esthetics and the half way point of both retromolar pads |
c
|
|
|
|
T/F
On your typodont case of 5 remaining mandibular teeth, the best method of developing esthetics is to use the natural teeth both incisally or occlusally and gingivally as a guide to setting your prosthetic teeth. |
False
We change the plane of occlusion |
|
|
|
T/F
Acrylic anterior prosthetic teeth do not have metal retentive pins and posterior teeth do not have diatoric openings. |
False
This is a tricky question, because technically there are situations where acrylic teeth can have these. Artificial porcelain teeth are mechanically retained. The posterior teeth are retained by acrylic resin in their diatoric holes. The anterior porcelain teeth are retained by acrylic resin surrounding their lingually placed retention pins. Artificial resin teeth are retained by a chemical union with the acrylic resin of the denture base, which occurs during laboratory processing procedures. |
