old.pt.come with set of compelete denture with tight denture in morning and become loose later in aday what is the cause:
- A. lack of posterior palatal seal.
- B. deflecting of occlusion.
- C. excessive relining of denture.
- D. inelasticity of cheek.
The most likely cause of a complete denture becoming tight in the morning and loose later in the day in an older patient is: A. Lack of posterior palatal seal.
Here's why the other options are less likely:
B. Deflecting of occlusion:
This could cause discomfort or instability, but not necessarily tightness followed by looseness.
C. Excessive relining of denture:
This would likely result in a loose denture from the start, not tightness initially.
D. Inelasticity of cheek:
While muscle tone can affect denture retention, it's not the most common cause of the specific pattern of tightness followed by looseness.
Explanation for A:
- The posterior palatal seal is crucial for denture stability, especially in older patients with decreased muscle tone.
- Overnight, tissues tend to swell due to fluid accumulation and gravity. This swelling can initially compress the denture against the palate, creating a tight feeling.
- During the day, as the tissues drain and return to their normal size, the lack of a proper posterior palatal seal can allow the denture to move around and become loose.
Additional factors to consider:
- Oral dryness can also contribute to denture looseness later in the day.
- Underlying bone loss or changes in jawbone shape can affect denture fit over time.
Recommendations:
- Consult a dentist to assess the denture fit and identify the specific cause of the problem.
- Relining the denture with a material that provides a better posterior palatal seal might be necessary.
- Using denture adhesives can offer temporary relief.
