Submucosal nodular chondrometaplasia in denture wearers

Area of Science:

• Oral pathology
• Dental prosthetics
• Histology

Background:

• Anterior maxillary flabby ridge tissue, often referred to as prosthesis fibroma, is common in denture wearers.
• The histological composition of this tissue is not fully understood.
• Understanding tissue changes is crucial for prosthetic success.

Purpose of the Study:

• To investigate the presence and nature of cartilaginous nodules within excised anterior maxillary flabby ridge tissue.
• To explore potential etiologies for observed chondrometaplasia.

Main Methods:

• Surgical excision of anterior maxillary flabby ridge tissue from 39 denture-wearing patients.
• Histopathological examination of the excised tissue specimens.
• Analysis for the presence of cartilaginous nodules.

Main Results:

• Cartilaginous nodules were identified in 15.4% of the examined tissue samples.
• The nodules were found within the excised anterior maxillary flabby ridge tissue.
• No specific correlation with patient demographics or denture characteristics was detailed in the abstract.

Conclusions:

• Chondrometaplasia is a potential finding in anterior maxillary flabby ridge tissue.
• Mechanical irritation activating mesenchymal cells is a possible cause.
• Remnant embryologic tissue cannot be ruled out as an alternative explanation.
