An examination of the edentulous mouth of an aged Pt who has wore maxillary complete dentures for many years against six mandibular teeth would probably show:
- A. Cystic degeneration of the foramina of the anterior palatine nerve.
- B. Loss of osseous structure in the anterior maxillary arch.
- C. Flabby ridge tissue in the posterior maxillary arch.
- D. Insufficient inter occlusal distance.
Out of the listed options, the most likely finding during an examination of the edentulous mouth of an aged Pt who has worn maxillary complete dentures for many years against six mandibular teeth is:
C. Flabby ridge tissue in the posterior maxillary arch.
Here's why the other options are less likely:
A. Cystic degeneration of the foramina of the anterior palatine nerve:
This is a rare complication and not a typical consequence of wearing dentures.
B. Loss of osseous structure in the anterior maxillary arch:
While some bone resorption is expected in the edentulous area, it's not specific to the anterior region and can occur throughout the maxilla.
D. Insufficient inter occlusal distance:
This is not a guaranteed finding and depends on various factors like denture construction, bite collapse, and individual anatomy.
Explanation of why C is the most likely finding:
- Flabby ridge tissue:
When maxillary complete dentures oppose only natural teeth in the mandible (six in this case), the posterior maxilla (the area behind the remaining teeth) experiences minimal functional stimulation. This lack of stimulation can lead to a decrease in bone density and the development of flabby ridge tissue, a soft and resilient tissue replacing the original alveolar bone.
It's important to note that these are general possibilities, and the specific findings during an examination would depend on various factors, including the individual's health, denture quality, and oral hygiene practices. Consulting a dental professional for a comprehensive evaluation is crucial for proper diagnosis and treatment planning.
