Introduction: Patients with deep bite occlusion may experience TMD symptoms without realizing it until they begin wearing the orthotic device fitted to address this issue. These changes can be significant enough to help them recognize their symptoms and potentially restore their bite to a more physiologically stable mandibular position permanently.

Aim: To apply neuromuscular dentistry principles in bimaxillary rehabilitation using porcelain crowns for a patient exhibiting signs and symptoms of TMJ dysfunction.

Methods: The diagnostic and follow-up procedures were based on the use of mandibular tracking (CMS), SEMG, and TENS.

Results: At the 8-year follow-up, there were no TMD signs or symptoms.

Conclusion: Neuromuscular dentistry is an effective method for diagnosing TMJ disorders, which can be treated with restorative crowns and bridges.
