To the 80 years old male patient the dentist performs the upper jaw Individual tray adjustments. Objectively: alveolar process of the upper jaw sharply and uniformly atrophied, maxillary tubers are not preserved, the torus is poorly defined. Buccal frenum and upper lip frenum are attached near the top of the alveolar process, palatal slope is gentle. What should be done with a custom tray to create a strong closing valve?

Extend the vibration line ("A"-line) boundaries

Extend the outer boundaries

The frontal area boundaries extending

The maxillary tubers area boundaries extending

The buccal frenum area overlay by individual tray

In 65 years old years female patient during edentulous jaws examination were identified the sharp bony prominences in the premolars area. The presence of these prominences adversely in orthopedic treatment of edentulous jaws. These prominences are responsible for balancing and the injury of the oral mucosa by denture. What are a doctor’s tactics in these clinical situation by way of preventing these complications?

Make a prosthesis, the boundary of which will be on top of the bony prominences

Hold insulation bony protrusions

Make a prosthesis with dual basis

Hold insulation bony protrusions and make the prosthesis with dual basis

Produce prosthesis must complete overlapping bony protrusions

The magnitude of the interocclusal gap affects:

All of the above.

Woman 47 years old, applied to the orthopedic treatment. After the examination, the chosen design of complete dentures on the upper and lower jaw. During the checking wax reproductions dentures: has interdental contact only one side - on the right, to the left one - the gap between teeth. What the mistake is made during the clinical stages?

Determined lateral occlusion*

Overstated interalveolar height in the left lateral side;

Deformed basis in determining the centric;

Received incorrect impressions

Determined frontal occlusion.

On the stage of check of complete dentures revealed prognathic relation of dentition, the frontal teeth without contact. What is the cause of this mistake?

Fixing the frontal bite registration;

Unspecified prothetic plane;

Interalveolar with low height;

Fixing the lateral bite registration;

Incorrect formation prothetic plane

Apply hard bases appropriate;

at significant atrophy of edentulous jaws;

when receiving imprint under control chewing pressure;

at the application of an intraoral registration central occlusion;

when using phonetic tests for staging teeth;

in all the above cases.

The method of determining the height of the lower part of face which gives the best aesthetic and functional effects – is
