• By observing the seal while the patient eats
• By applying pressure to the seal with a spoon
• By analyzing a mold of the seal
• By having the patient read out loud
• By measuring the seal with a ruler

Applying: Which of the following factors can affect posterior palatal seal?

• Tooth position
• Muscle tone
• Tongue position
• All of the above
• None of the above

Analyzing: How does posterior palatal seal differ from anterior seal?

• Posterior seal is located further back in the mouth
• Anterior seal is located further back in the mouth
• Posterior seal is made from a different material
• Anterior seal is made from a different material
• There is no difference between the two

Evaluating: In which of the following situations might posterior palatal seal be inadequate?

• When the patient has a high-arched palate
• When the patient has a narrow palate
• When the patient has a wide palate
• When the patient has a flat palate
• All of the above

Remembering: Which of the following is NOT a type of posterior palatal seal?

• Tissue conditioning
• Tissue-borne
• Tissue-supported
• Tissue-integrated
• Tissue-borne and tissue-supported

Understanding: What is the purpose of a tissue-integrated posterior palatal seal?

• To provide support to the denture
• To anchor the denture in place
• To improve the fit of the denture
• To improve the seal between the denture and the palate
• All of the above

Applying: How is a tissue-supported posterior palatal seal made?

• By bonding the denture to the palate
• By attaching a bar to the denture and the palate
• By using a combination of suction and mechanical retention
• By attaching a wire to the denture and the palate
• None of the above

Analyzing: How does a tissue-borne posterior palatal seal differ from a tissue-supported seal?

• Tissue-borne seals are made from a different material
• Tissue-borne seals are attached to the denture in a different way
• Tissue-borne seals provide less support to the denture
• Tissue-borne seals are less effective at sealing the denture to the palate
• None of the above

Evaluating: In which of the following situations might a tissue-integrated posterior palatal seal be inappropriate?

• When the patient has a large tongue
• When the patient has a small palate
• When the patient has a high-arched palate
