Occlusal Practice in Removable Prosthodontics

Self-Study Examination

Instructions: After studying the text answer the following true/false or multiple choice questions.  Remember, there's only one answer to each question.

1. Which of the following are not types of partial dentures:

a) tooth supported
b) tooth and mucosa supported
c) occlusal restoration supported
d) mucosal supported

2. It is extremely likely that a poorly designed occlusion will be immediately manifested by an unstable denture if the denture is totally tooth supported.

a) true
b) false

3. Which is not included in the EDEC principle?

a) examination
b) design
c) education
d) execute
e) check

4. Factors that might compromise the stability of full dentures include all except:

a) unilateral prematurities
b) occlusal tables that are too large
c) injudicious placement of teeth
d) poor esthetics

5. For stability in complete dentures, it is important that posterior contacts occur unilaterally in centric relation.

a) true
b) false

6. When making a new denture, it would be inappropriate to use the conformative approach if:

a) there is inadequate freeway space
b) there is evidence of excessive wear
c) crossbite
d) anterior posturing
e) all of the above

7. The re-organized approach may be indicated if there is:

a) TMJ dysfunction
b) grossly over-closed vertical dimension
c) inability to wear the existing denture due to instability
d) a broken tooth on the denture

8. Facebow records are no longer needed to determine the inter-arch relationship as more accurate measuring devices have been developed.

a) true
b) false

9. The ideal occlusion that is developed for dentures is:

a) one that will limit the tilting of the dentures
b) one that uses the least restorative material
c) one that utilizes porcelain teeth only
d) one where only posterior teeth are in occlusion

10. Denture teeth without cusps are ideal for a patient with a balanced dynamic occlusion.

a) true
b) false

11. Which of the following is not a scenario of a condition known as “new combination syndrome”?

a) complete maxillary denture opposed by partly dentate mandibular arch
b) complete mandibular denture opposed by partially dentate maxilla
c) complete mandibular denture opposed by implant-retained maxillary denture
d) complete maxillary denture opposed by implant-retained mandibular denture

12. Ways of reducing displacing forces on a maxillary denture by a dentate mandibular arch include:

a) coordinating the maxillary plane of occlusion to the mandibular movement
b) coordinating the mandibular teeth with the maxillary movement
c) utilizing denture adhesive
d) utilizing zero-degree teeth
e) utilizing yoga exercises

13. Implant-retained lower dentures may cause a significant change in the chewing pattern and this may not occur for some time after placement of the prosthesis.

a) true
b) false

14. Criteria for denture success is:

a) stability
b) esthetics
c) patient satisfaction
d) all of the above

15. An ideal occlusion in removable prosthodontics is one which:

a) increases de-stabilisating forces to a level that exceeds the denture’s retentive capacity
b) increases de-stabilisating forces to a level that is equal to the denture’s retentive capacity
c) reduces de-stabilisating forces to a level that is within the denture’s retentive capacity
d) reduces de-stabilisating forces
