Summary
This study shows promising early results for TMJ Concepts and Biomet Lorenz total joint replacements in temporomandibular joint (TMJ) reconstruction. These FDA-approved systems offer a viable surgical option for TMJ disease, with minimal complications reported.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomedical Engineering
- Orthopedic Surgery
Background:
- Total alloplastic temporomandibular joint (TMJ) replacement is a recognized surgical option for TMJ disease.
- Various degenerative conditions and traumatic injuries necessitate TMJ reconstruction.
- TMJ Concepts and Biomet Lorenz systems are FDA-approved prostheses with a history of reliability.
Observation:
- A prospective trial investigated the early findings of TMJ Concepts and Biomet Lorenz total joint replacement systems.
- The study included seven patients undergoing 12 total TMJ replacements (3 TMJ Concepts, 9 Biomet Lorenz).
- Follow-up ranged from six months to three years.
Findings:
- Average postoperative mouth opening was 29.7 mm (range 25-35 mm).
- Average pain score was 1.7 (range 0-3) on a 0-10 scale.
- Complications were minimal, including one case of sensory disturbance and two joint dislocations.
Implications:
- These early results suggest that TMJ Concepts and Biomet Lorenz systems are effective for TMJ reconstruction.
- Further long-term studies are warranted to confirm the durability and efficacy of these prostheses.
- Total alloplastic TMJ replacement offers a promising solution for patients with debilitating TMJ disorders.
