Single Complete Denture

Question 1

What teeth are usually lost first?

Answer 1

Maxillary

Question 2

What are some forms of stress reduction?

Answer 2

• Processed resilient denture liner
• Overdenture (root anchored)
• Implant retained overdenture

Question 3

Uneven occlusal planes may apply excessive forces and lead to

Answer 3

denture fracture

Question 4

Greater forces may cause

Answer 4

• Displacement
• Fracture of denture due to flexure
• Severe residual ridge resorption

Question 5

Tooth malpositions in opposing arch will

Answer 5

decrease stability (extrusion, tipping, rotation)

Question 6

Why may occlusal adjustments of natural teeth be necessary?

Answer 6

• Reduce severe curve of Spee levels
• Reduce supra-erupted teeth that may lead to interferences
• Recontour rotated teeth to permit contacts on flat surfaces

Question 7

Combination syndrome occurs when

Answer 7

A maxillary complete denture opposes natural mandibular anterior teeth

Question 8

Combination syndrome is initiated by

Answer 8

loss of maxillary anterior bone

Question 9

Combination syndrome consists of

Answer 9

• Resorption of premaxilla
• Hypertrophy of max tuberosities
• Papillary hyperplasia of hard palate
• supraeruption of mandibular anteriors
• Loss of alveolar bone and ridge height beneath the mandibular removable partial denture bases

Question 10

Combination syndrome may lead to

Answer 10

• Loss of VDO
• Occlusal plane discrepancy
• Marked pseudo-Class III jaw
• Anterior repositioning of the mandible
• Poor prosthesis adaptation
• Epulis fissuratum

Question 11

What are considerations when making occlusal rims?

Answer 11

Flat surfaces for opposing teeth, no inclines
-If step exists in occlusal plane, provide flat areas for opposing natural teeth

Question 12

What size cusps are desirable for posterior?

Answer 12

Moderate to shallow cusps

Question 13

When selecting teeth, it is better to use

Answer 13

anatomic/semi anatomic teeth and ajust their cusps as needed

Question 14

When do you use inter cast metal mesh?

Answer 14

• If denture has fractures in past (usually from heavy forces from natural teeth, occlusal contacts, impingement ona. bony midline)

Question 15

Never use _____ teeth opposing naural dentition or acrylic denture teeth

Answer 15

porcelain
