1.Roentgenographic Cephalometric Study for Normal Occlusion in Korean Adults According to the Ricketts Analysis.
Yeungnam University Journal of Medicine 1990;7(2):131-139
The purpose of this study was to assess the skeletal characteristics of the maxillofacial norms and the interpretation of craniofacial relations in Korean adults by applying the Ricketts Analysis. The factors of the applied lateral cephalometric measurements were composed of the 10 factor analysis (Summary Analysis) and 7 internal structures to be suggested by Ricketts. Lateral cephalograms were obtained from 60 subjects over 21 years old that consisted of 30 males and 30 females with normal occlusion, acceptable profile. The results were as follow: 1. The tables of means, standard deviations in each item and sex were made. 2. The author performed whether there was significance (P<0.05) between the registered male and female's measurement in each item.

2.Roentgraphic Cephalometric Standard for Maxillofacial Normals with Ideal Occlusion in Korean Adults.
Yeungnam University Journal of Medicine 1989;6(1):141-149
The purpose of this study was to aid the case analysis and diagnosis of the maxillofacial deformities for orthognathic surgery. The applied method for analysis was a Cephalometrics Orthognathic Surgery (COGS) by Burstone. Lateral cephalograms werer obtained from 59 subjects over 21 years old, that consisted of 30 males and 29 females with normal occlusion, acceptable profile. The results were as follows: 1. The author made the tables of means, standard deviations in each item, sex. 2. The author performed whether there was significance (P<0.05) between the registered male and female's measurement in each item.

174 patients who visited in the Department of Dentistry, College of Medicine, Yeungnam University from 1983. 7. 15 to 1986. 11. 30 were surveyed on the tendency of patient distribution and the state of Angle's classification. The results were as follows 1. There was increased visiting rate of patient per year. Female outnumbered male by a ratio of 1.3:1. 2. 8-15 age group was 74% in total visiting in the most frequency. The average visiting numbers of each month were higher among the vacation and was about 74% in that period. 3. As showed the living distribution, Nam Go and Su Sung Gu's patients were 53% of the total. 4. As the motive of visiting in Dental Department, patient of 30% in total patients visited for themself to receive orthodontic treatment and other was introduced patients. 5. By classification, Class I malocclusion was 63% in total visiting patient, Class II malocclusion 17%, Class III malocclusion 20%. Crowding among Class I malocclusion was 60%.

he Magnetic. resonance imaging has been used widely to evaluate the disk position without any interruption of the TMJ structures, and the dynamic MRI presenting computed serial imaging or the video-recorded simulation images is thought to be very effective to evaluate the disk position under function. This is to study the correlation between the clinical diagnosis and the findings of dynamic MRI for diagnosis of internal derangement of the 7 patients were examined clinically, and the movement of TMJ meniscus was reviewed in the dynamic MRI. MRI was very reliable to diagnose the amount of anterior displacement of articular disc, the structural abnormality of temporomandibular joint, the cause of functional limitation, and to differentiate the muscle related pain & dysfunction.

The purpose of this study was to evaluate the amount and interrelationship of the soft and hard tissue change after mandibular setback surgery in skeletal Class III malocclusion. The sample consisted of 25 adult patient (12 male and 13 female) who had severe anteropostrior skeletal discepancy. These patient had received presurgical orthodontic treatment and surgical treatment which is bilateral sagittal split ramus osteotomy. The presurgical and postsurgical lateral cephalograms were evaluated. The computerized statistical analysis was carried out with SPSS/PC program. The result were as follows: 1. After mandibular bilateral sagittal split ramus osteotomy, lower facial soft tissue horizontal posterior changes were high significance value. but vertical soft tissue changes were low significance value. 2. After mandibular bilateral sagittal split ramus osteotomy, relative upper lip protrusion increased(p<0.01) and relative lower lip protrusion decreased(p<0.01) and lower facial soft tissue thickness increased(p<0.01).

Mandibular condylar fracture is common in mandibular fractures. Unlike other facial, skeletal fractures, most of mandibular condylar neck or head fractures are treated with closed reduction and subsequent functional therapy is essential for preventing complications including ankylosis, arthrosis and growth disturbance. From January, 2000 to September, 2002, we have treated 15 cases of mandibular condylar fractures with closed reduction by using functional appliance with bite block. Among these cases, we report a case of 14-year-old female with mandibular condylar neck fracture, resulted in good clinical and radiographic progress.
