Abstract
교합안정장치가 비호흡에 미치는 영향을 평가하고자, 측두하악장애 및 호흡기질환이 없는 17명의 건강한 20대 성인을 대상으로 앙와위(仰臥位) 에서 Aerophone Ⅱ Voice Function Analzyer (KAY elemetrics, USA)를 이용하여 교합안정장치 장착 전후의 공기역학적 검사를 시행하여 다음과 같은 결과를 얻었다. 1. 최대 기류량은 교합안정장치를 장착한 후 유의한 차이는 없었다. 2. 폐활량은 교합안정장치를 장착한 후 유의한 차이는 없었다. 3. 교합안정장치를 장착한 후 1회 호흡의 지속시간은 유의하게 증가하였다 (P ≶ 0.05).
To evaluate the effect of occlusal stabilizing appliance on nasal respiration in supine position, this study was examined Subjects were composed of dental students without any signs and symptoms of temporomandibular disorders and respiratory diseases, The age of subjects was limited to be between 22 and 28 years, Maximum flow rate, vital capacity and duration of a respiration were measured, analyzed and evaluated wIthout and with appliance in supine position by Aerophone II,
The obtained results were as follows
1 The maximum flow rate of a respiration with occlusal stabilizing appliance was no significant difference compared to that without occlusal stabilizing appliance
2. The vital capacity of a respiration with occlusal stabilizing appliance was no significant difference compared to that without occlusal stabilizing appliance,
3 The duration of a respiration with occlusal appliance was significantly increased compared to that without occlusal appliance (P ≶ 005).
