The invention discloses a temporomandibular joint deformity correction system and a method for making a personalized deformity correction device. The method comprises 1, analyzing an occlusal function through an occlusion analysis system to determine an occlusion position, 2, preparing original upper and lower jaw models according to the occlusion analysis system and re-positioning an occlusion plate through patient wearing with the original upper and lower jaw models, 3, carrying out re-examination on the patient each month, 4, after re-examination, determining whether the occlusion position is correct and carrying out deformity correction, 5, stabilizing the occlusion position and carrying out a tooth arrangement test, and 6, producing the personalized deformity correction device according to the tooth arrangement model after the tooth arrangement test. Compared with the prior art, the system realizes personalized tooth arrangement through combination of an adjustable frame, function analysis and projective measurement analysis according to the patient's skull surface type, utilizes a covering material to precisely control the position of the occlusion position, prevents occlusion position change, evaluates the tooth movement amount in a visual state through 3D data scanning before and after tooth arrangement and provides good deformity correction treatment guidance for later treatment.
