Summary
Abnormal condylar surface forms are common in edentulous patients, affecting 71%. Erosion was the most frequent abnormality, particularly in older patients and those with unstable dentures.
Area of Science:
- Dentistry
- Radiology
- Oral and Maxillofacial Surgery
Background:
- Temporomandibular disorder (TMD) is a common condition affecting the jaw joint.
- Edentulous patients may present with various oral health issues.
- Condylar surface morphology can be affected by aging and prosthetic status.
Purpose of the Study:
- To assess the incidence of abnormal condylar surface forms in edentulous patients.
- To investigate the relationship between these abnormalities and patient factors.
- To classify the types of observed condylar abnormalities.
Main Methods:
- Zonography was utilized to examine the condylar surfaces of edentulous patients.
- Patients presented with chief complaints unrelated to temporomandibular disorder.
- Data were collected on patient age and denture stability.
Main Results:
- Abnormal condylar surface forms were detected in 71% of the subjects.
- Bilateral abnormalities were present in 66% of affected individuals.
- Erosion (60.6%) was the most prevalent abnormality, followed by flattening, osteophyte, and concavity.
Conclusions:
- Abnormal condylar surface forms are highly prevalent in edentulous patients.
- Increased incidence of these abnormalities was noted in patients over 70 years old and unstable denture wearers.
- These findings highlight the importance of evaluating condylar morphology in edentulous populations.
