Question 285 (part 2) · LDEK · Functional disorders of the masticatory system
In order to assess the TMJ various test and functional manipulations are used. One of them is resiliency test. Indicate true statements regarding this test:
1) thank to resiliency test we may assess the compression or distraction of articular gap with an accuracy of 0.1 mm;
2) resiliency test is performed with the use of articulation paper of 100 µm;
3) resiliency test is performed with the use of articulation foil of 60 µm;
4) resiliency test is performed by placing the tin foil of 0,3 mm thickness, which prevents the occlusal contact on opposite side and holding the foil of 21 µm thickness during clenching the teeth in maximum intercuspal contact;
5) this test is always negative in normal occlusal conditions thank to the estasticity of TMJ tissues.
Correct answer is:
2) resiliency test is performed with the use of articulation paper of 100 µm;
3) resiliency test is performed with the use of articulation foil of 60 µm;
4) resiliency test is performed by placing the tin foil of 0,3 mm thickness, which prevents the occlusal contact on opposite side and holding the foil of 21 µm thickness during clenching the teeth in maximum intercuspal contact;
5) this test is always negative in normal occlusal conditions thank to the estasticity of TMJ tissues.
Correct answer is:
- A. 1,2.
- B. 2,4.
- C. 4,5.
- D. 3,5.
- E. 1,6.
Hint
Focus on how a tin-foil spacer on one side and a thin control foil on the other reveal abnormal compressibility of the joint.
