Question 187 · LDEK · Partial dentures
Indicate the steps and their right order in establishing occlusal relationship in partially edentulous patients with the correct occlusal vertical dimension:
1) evaluate the occlusal rims;
2) establish physiological resting position of the mandible;
3) establish the occlusal vertical dimension;
4) examine the correct tooth contacts in the supporting zones before the insertion of the occlusal rims;
5) insert the occlusal rims into the patient’s mouth and check whether the rims are trimmed to the occlusal vertical dimension;
6) plastify the occlusal rims with a hot knife;
7) insert the occlusal rims and check whether the distance between the natural teeth is approx. 0.2 cm;
8) insert the plastified occlusal rims into the patient’s mouth and ask the patient to close the mouth;
9) check the correct tooth contacts; 10) mark the midline, smile line and canine lines; select the color of the artificial teeth; 11) after a removal of the occlusal rims from the patient’s mouth, check the correct contacts of the natural teeth on working casts.
The correct answer is:
2) establish physiological resting position of the mandible;
3) establish the occlusal vertical dimension;
4) examine the correct tooth contacts in the supporting zones before the insertion of the occlusal rims;
5) insert the occlusal rims into the patient’s mouth and check whether the rims are trimmed to the occlusal vertical dimension;
6) plastify the occlusal rims with a hot knife;
7) insert the occlusal rims and check whether the distance between the natural teeth is approx. 0.2 cm;
8) insert the plastified occlusal rims into the patient’s mouth and ask the patient to close the mouth;
9) check the correct tooth contacts; 10) mark the midline, smile line and canine lines; select the color of the artificial teeth; 11) after a removal of the occlusal rims from the patient’s mouth, check the correct contacts of the natural teeth on working casts.
The correct answer is:
- A. 1,4,7,6,8,9,10,11.
- B. 1,2,3,5,6,8,10.
- C. 2,3,1,5,6,8,10,11.
- D. 2,3,4,5,6,7,10.
- E. 3,2,1,5,6,8,10,11.
Hint
When the patient's own teeth still hold the bite in the support zones, ask whether rest position and occlusal height need to be established at all.
