Published: 23 July, 2022 | Volume 7 - Issue 2 | Pages: 005-009

Case report: This case report aimed to evaluate temporomandibular joint activity in a patient with the temporomandibular disorder before and after disclusion time reduction (DTR) therapy.
Results: Positive changes in joint health were observed in the patient after the DTR treatment. 
Conclusion: The joint vibration analysis objectively showed significant results with the disclusion-time reduction therapy. The measured parameters were closer to the reference values. Thus, DTR is an effective method to treat TMJ disorders, based on Piper’s classification.
