Progressive idiopathic condylar resorption: Three case reports.
1Private practice, Quebec City, Quebec, Canada.
Summary
Progressive condylar resorption, a rare TMJ disease, affects young women, causing bone loss and open bite. Conservative management is often effective, with surgery reserved for severe cases.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthodontics
- Rheumatology
Background:
- Progressive condylar resorption (PCR), or idiopathic condylar resorption, is an uncommon degenerative temporomandibular joint (TMJ) disease.
- Primarily affects adolescent girls and young women, leading to significant structural changes in the mandible.
Observation:
- The condition causes loss of condylar bone mass, decreased mandibular ramal height, and steepened occlusal and mandibular plane angles.
- Anterior open bite is a characteristic clinical manifestation.
- This review examines the pathogenesis and clinical management of TMJ arthrosis through three case reports.
Findings:
- TMJ arthritic disease warrants recognition as a distinct pathologic entity within dentistry, analogous to orthopedic discussions of arthritis.
- Treatment goals focus on restoring function and reducing pain.
- Management strategies range from noninvasive therapies to surgical interventions, with a strong emphasis on conservative approaches.
Implications:
- Most patients benefit from noninvasive treatments, highlighting the importance of disease prevention and conservative management.
- Surgical decisions for TMJ osteoarthrosis should be guided by patient response to noninvasive care, functional assessment, and quality of life impact.
