Abstract

The aim of this study was to investigate clinical assessment and cephalometric characteristics in 10s patients with condylar resorption, who visited in the Department of Oral Medicine Kyungpook National University Hospital at 2006, by use of panorama, transcranial view and lateral cephalometric radiograph. The results were as follows; 1. Clinical assessment 1) Total number of patients were 59. Female was 47 and male was 12, Females were predominant and patient's age ranged from 12 to 19. 2) Most of the patients had Grade II condyle resorption. 3) The number of who had Class I occlusion was 27, which was the largest group. The number of patients with openbite was 20. Average overjet was 3.58mm and average overbite was 0.97mm. 4) Most of the patients had parafunctional habit. 5) The patients of showing the pain in condylar resortion was 41 and the case of not showing the pain was 18. 6) Treatment duration of 23 patients were less than 1 month, 28 patients were treated with supported therapy. 2. Cephalometric Characteristics 1) A 16-year-old female patients showed smaller SNA, SNB and larger articular angle significantly as compared with those of normal group. 2) A 17-year-old female patients showed smaller SN, SAr, TPFH, ramus height and larger SN-GoMe, FMA, articular angle significantly as compared with those of normal group. 3) Over 18 years old female patients showed smaller SN, SNB, TPFH, ramus height and larger ANB, FMA, SN-GoMe, LAFH, articular angle, gonial angle significantly as compared with those of normal group. 4) Over 18 years old male patients showed smaller SN, TPFH, ramus height and larger FMA, SN-GoMe, LAFH, articular angle, gonial angle significantly as compared with those of normal group. 5) There was no significant difference between 10s and normal group in mandibular body length.

2006년 한 해 동안 경북대학교 구강내과에 내원한 하악과두의 형태적 변이가 관찰된 10대 과두흡수 환자를 대상으로 임상검사와 악안면 골격형태를 분석하여 다음과 같은 결론을 얻었다. 1. 임상적 평가 1) 10대 과두흡수 환자는 59명으로 여자는 47명, 남자는 12명으로 여자에서 월등히 많이 유발되었다. 환자의 연령분포는 12세가 2명, 14세가 9명, 15세가 4명, 16세가 8명, 17세가 12명, 18세가 12명, 그리고 19세가 12명으로 나타났다. 2) 과두의 편평화나 침식, 과두형태의 변형이 초래된 Grade II를 많이 나타냈다. 3) Class I 교합자가 27명으로 가장 많았고, 개교합이 동반된 경우는 20명, 평균 overjet은 3.58mm, overbite는 0.97mm를 보였다. 4) 과두흡수 부위의 통증을 호소한 경우는 41명, 통증을 호소하지 않은 경우가 18명이었다. 5) 이갈이 습관을 26명, 이악물기 습관은 24명이 보고하였다. 6) 환자의 치료기간은 1개월 미만이 23명, 보조요법으로 치료한 경우가 28명이었다. 2. 악안면 골격 형태 평가 1) 16세 여자환자에서 SNA, SNB는 유의한 작은 값을 나타냈고 articular angle은 유의한 큰 값을 보였다. 2) 17세 여자환자에서 SN, SAr, TPFH와 ramus height가 유의한 작은 값을, SN-GoMe, FMA 그리고 articular angle은 유의한 큰 값을 나타냈다. 3) 18세 이상 여자 환자에서는 SN, SNB, TPFH, ramus height은 유의한 작은 값을, ANB, FMA, SN-GoMe, LAFH, articular angle, gonial angle은 유의성 있는 큰 값을 보였다. 4) 18세 이상 남자 환자에서는 SN, TPFH, ramus height은 유의한 작은 값을 FMA, SN-GoMe, LAFH, articular angle, gonial angle은 유의성 있는 큰 값을 보였다. 5) mandibular body length는 10대 과두흡수 환자에서 정상인과 차이가 없었다. 10대 과두흡수의 특징은 임상적으로 통증호소는 심하지 않으나 골소실이 빠르게 일어나서 이환측 과두에서 후방지지의 갑작스런 상실이 초래되는 특발성 과두흡수의 형태를 많이 나타내며 개교합 발생 비율도 높았다. 근골격계 성장이 완료되지 않은 10대에 특히 수직적 악안면 골격형태로 인한 부하의 집중과 이상기능활동에 의해 하악과두에 과도한 부하가 가해지면 과두흡수가 더욱 쉽게 일어날 수 있으며, 결국 악골의 성장을 저해하고 안모에 악영향을 미칠 수 있을 것으로 생각한다.
