STABILITY AD SUPPORT IN CD

Remembering: What is the most common cause of instability in complete dentures?

• Improper denture base adaptation
• Excessive oral muscular activity
• Inadequate occlusal vertical dimension
• Incorrect denture base contour
• Improper tooth placement

Understanding: Which of the following is NOT a characteristic of a well-made denture?

• Properly balanced occlusion
• Adequate retention and stability
• Natural appearance of teeth
• Complete coverage of alveolar ridge
• Excessive bulkiness

Applying: A patient complains that their lower denture feels loose and moves excessively. Which of the following is the MOST likely cause?

• Inadequate tooth set-up
• Excessive oral muscular activity
• Incorrect denture base contour
• Improper denture base adaptation
• Lack of patient education on denture care

Analyzing: A patient has a severely resorbed alveolar ridge and is experiencing difficulty wearing their upper denture. Which of the following would be the MOST appropriate treatment?

• Add a dental implant for support
• Increase the thickness of the denture base
• Reduce the occlusal vertical dimension
• Apply denture adhesive to increase retention
• Add a palatal bar for support

Evaluating: A patient's complete dentures have been in place for several years and are now causing them discomfort. Which of the following is the MOST likely cause?

• Incorrect tooth position
• Excessive oral muscular activity
• Denture base adaptation is no longer sufficient
• Resorption of alveolar ridge
• Tooth set-up is incorrect

Remembering: What is the minimum number of denture bearing areas required for stability in complete dentures?

• 2
• 4
• 6
• 8
• 10

Understanding: Which of the following is NOT a factor in determining the occlusal vertical dimension in complete dentures?

• Tooth position
• Alveolar ridge height
• Patient's age
• Patient's gender
• Patient's occlusal scheme

Applying: A patient with a severely resorbed alveolar ridge is seeking treatment for their complete dentures. Which of the following is the MOST appropriate course of action?

• Add a palatal bar for support
• Increase the thickness of the denture base
• Reduce the occlusal vertical dimension
• Apply denture adhesive to increase retention
• Add a dental implant for support

Analyzing: A patient is experiencing discomfort while wearing their complete dentures. Which of the following is the MOST likely cause?

• Incorrect tooth position
• Excessive oral muscular activity
• Resorption of alveolar ridge
• Denture base adaptation is no longer sufficient
• Tooth set-up is incorrect

Evaluating: A patient has recently received a new set of complete dentures and is experiencing difficulty with retention and stability. Which of the following is the MOST likely cause?

• Improper denture base adaptation
• Excessive oral muscular activity
• Inadequate occlusal vertical dimension
• Incorrect denture base contour
• Improper tooth placement
