Increased overbite and craniomandibular disorders--a clinical approach
1Department of Orthodontics, Karolinska Institutet, Huddinge, Sweden.
Summary
A fixed lingual arch appliance with an anterior bite plane effectively treated craniomandibular disorders (CMD) and reduced increased overbite in adult patients. Symptoms resolved within weeks, with lasting pain relief observed over two years.
Area of Science:
- Dentistry
- Orthodontics
- Craniomandibular Disorders
Background:
- Craniomandibular disorders (CMD) and increased overbite often present complex challenges in adult patients.
- Previous treatments like splints and bite plates yielded unsatisfactory results for these patients.
Observation:
- A novel maxillary fixed lingual arch with an anterior bite plane appliance was utilized.
- This appliance created molar separation and restricted occlusal contact to the anterior teeth.
Findings:
- All 11 patients reported significant relief from CMD symptoms, including headaches and temporomandibular joint pain, within 1-2 weeks.
- Over a mean of 3 months, the appliance reduced overbite by approximately 3.4 mm, flattened the curve of Spee, and established molar contact.
- Long-term follow-up (2 years) confirmed sustained freedom from CMD pain.
Implications:
- This appliance offers a viable treatment option for adult CMD patients with increased overbite.
- It provides a foundation for subsequent orthodontic or prosthetic rehabilitation to achieve stable occlusal and vertical dimensions.
- The findings suggest a minimally invasive approach for managing complex CMD cases.
