Objective: To understand the distribution of temporomandibular disorder in patients with malocclusion. METHODS: Eighty-eight patients with pre-correction wrong-off were evaluated using the Helkimo index. Results: The main symptom index Ai0 was 50%, Ai was 4 4.3 2%, Ai was 5.68%; clinical examination index Di 0 was 32.95%, Di was 5 1.14%, Di was 14.77% , Di is 1.14%. Masticatory muscle abnormalities and joint noise are the most common symptoms and signs.
