Complete Denture Trial Insertion:

Question 1

Trial denture appointment:

Answer 1

1. Check vertical dimension of occlusion and rest
2. Prove centric relation records
3. Make protrusive record
4. Evaluate aesthetics and phonetics
5. Posterior Palatal seal

Question 2

Methods of Assessing the VDO:

Answer 2

• Physiologic rest position
• Phonetics and aesthetics
• Swallowing
• Comparison of the old denture

Closest speaking space is used for the final test to determine if the vertical dimension that we have chosen is correct

• “S” sounds
• Count from sixty to seventy

Question 3

Prove the Centric Relation Record:

Method used to verify your mounting:

Answer 3

• Observe any shift in the upper denture
• Look for even contact of the posterior teeth bilaterally

Question 4

Proof of Mounting - CR Record:

Answer 4

• Soften the compound over the Bunsen burner
• Place the compound onto the occlusal surfaces of the mandibular posterior teeth
• Temper the compound in water bath set at proper temperature (110°) and smooth it with your wet gloved finger

Question 5

Providing the Record:

Answer 5

• Place the new record onto the master casts
• Loosen the centric locking screw
• If the maxillary teeth contact the indentations exactly as they did in the mouth, you have proven that your original centric record was correct

The articulator must close in the hinge position without condylar displacement

Question 6

Protrusive Record:

Clinical steps:

Answer 6

• Practice the protrusive movement with patient before making the record
• Mandible must be brought forward 5-6 mm short of tooth contact while maintaining the mandible in the midline

Question 7

Setting the Condylar inclination:

Answer 7

• Loosen the centric locking pins
• Observe the space that develops between the condylar elements when the casts are completely seated in the protrusive record
• Select a condylar inclination that best fits the space
• Place the condylar inclination insert into position

Question 8

Esthetics and Phonetics:

Facial support affected by:

Answer 8

• Position of the incisal edge
• Thickness and contour of the labial flange
• Gingival contours

Question 9

Phonetic Evaluation:

Answer 9

Fricative sounds:

• Patient should be able to make a clear “f” and “v” sound with the maxillary incisal edges against the lower lips

Phonetics Sibilants: During the production of the “S” and “Z” sound

1. The anterior and posterior teeth should not touch
2. These should be no hissing or air loss

Question 10

Posterior Palatal Seal:

Answer 10

• Draw a line 1 mm anterior to the posterior extension of the denture
• Draw a second line anterior to first in butterfly pattern
• Carve the bead seal with a discoid cleoid
• It should be 1 mm in depth
• It should feather out into hamular notch
• It should not extend onto the tuberosities or onto a torus
