Angle's Class II Division 2 Malocclusion Treated by Bioprogressive Mechanism: Report of a Case.: Sang Kil Byun, Hee Kyung Lee, Byung Rho Chin, Meung Chul Oh; Yeungnam Univ J Med. 1987;4(1):151-156. Published online August 31, 1987; DOI: https://doi.org/10.12701/yujm.1987.4.1.151

Abstract PDF: A 25 year and 7 month old man patient who had Angle's class II division 2 malocclusion combined with anterior crowding of upper & lower part was treated by bioprogressive mechanism. After setting out objectives through the use of V. T. O., we programmed a sequence of mechanic. The possible objectives of treatment in the class II division 2 malocclusion can be listed as follows. 1) Relief of crowding & irregularities. 2) Relief of anterior gingival trauma & correction of interincisal inclination. 3) Correction of buccal segment relationship We'd applied the class II intermaxillary elastics, Quad helix, utility arch wire and sectional arch wire in order to achieve anticipated objectives. As compared with pre & post treatment cephalogram, the result accomplished by this mechanics showed to us that interincisal angle was improved and favorable molar relationship was achieved.

Surgical Treatment of Phenytoin Induced Gingival Hyperplasia: A Report of Case.: Sang Kil Byun, Hee Kyung Lee, Byung Rho Chin, Meung Chul Oh; Yeungnam Univ J Med. 1986;3(1):383-386. Published online December 31, 1986; DOI: https://doi.org/10.12701/yujm.1986.3.1.383

Abstract PDF: Enlargement of the gingival caused by phenytoin. An anticonvulsant used in the treatment of epilepsy, occurs in some of the patients receiving the drug. Its incidence varies from 3 to 62 percent, with the greater frequencies in younger patients. The hyperplasia is usually generalized throughout the mouth, but is more severe tendency in the maxillary and mandibular anterior regions. 18 year old male patient was admitted to our Department of Dentistry with the complaint of generalized painless gingival swelling. After the consult of the N.M. and laboratory study, the gingivectomy and gingivoplasty was performed. The periodontal pack and tin foil was applied on the attached gingival to protect a surgical site and bleeding control. We obtained a good result of improved esthetics and function.

Abstract PDF: 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%.
