A patient was 19-year 5-month-old female who had the chief complaint of crowding on maxilla and mandible and right side posterior buccal cross bite, had not complaint as regards mandibular asymmetry. After the close examination, vertical discrepancy on the left side condyle in CO-ICP sliding was confirmed. Forward discrepancy was added in this sliding while the orthodontic treatment was performing without much changing of the right side condylar position, and more, the deformity of the left side condyle was advanced, hence the surgical orthodontic treatment was necessary to achieve the morphological and functional treatment goal for her was obvious. The patient was fully informed about surgical orthodontic treatment and she gave her informed consent to the treatment smoothly by the explanation using the articulator and CPI data, nevertheless her chief complaint was merely the crowding on the maxilla and mandible, and the right side posterior buccal cross bite. The deformity of the condyle was not advance after the surgical orthodontic treatment. It was suggested that using the articulator and CPI data as one of the examinations was also useful to inform the patient the problem except the chief complaint in some cases resulting in giving the patient the higher quality of the treatment. We will apply the articulator positively to gain more informations from the patient and 'informed consent' in the orthodontic and the surgical orthodontic cases.
