연구 목적: 이 연구의 목적은 결손부 내로 낮게 연장된 폐쇄장치와 높게 연장된 폐쇄장치를 환자의 만족도 및 선호도를 통해 비교하는 것이다. 연구 재료 및 방법: 상악절제술을 받고 보철치료를 받은 11명을 대상으로 결손부 내의 연장부의 높이가 다르고 나머지 형태가 통일한 폐쇄장치를 각 환자 당 2개씩 제작하였다. 각 폐쇄장치를 2달 간 번갈아 사용하게 한 후 환자에게 폐쇄장치의 사용편의성, 발음, 비음성, 누출, 저작에 대한 폐쇄장치들의 만족도를 설문을 통해 조사하고, 최종적으로 환자들의 선호도와 그 이유를 조사하여 분석하였다. 폐쇄장치에 따른 차이를 Wilcoxon signed rank test를 사용하여 분석하였다 (P< .05). 결과: 구개 결손부 내로의 연장부의 높이가 낮은 폐쇄장치와 높은 폐쇄장치에 대해 환자들의 평가는 차이가 없었다 (P > .05). 그리고 높은 폐쇄장치와 낮은 폐쇄장치에 대한 환자들의 선호도는 다양하였다. 결론:상악절제술 후 개구가 제한되는 상황이나 보철물의 삽입로가 제한되는 등 특수한 상황에서는 연장부가 낮은 높이의 폐쇄장치가 추천될 수 있다.
Abstract
Purpose: The purpose of this study was to compare the functional abilities of the low bulb obturators with those of high bulb obturators in terms of patients’evaluation. Material and methods: This study included 11 maxillectomy patients who underwent postoperative prosthodontic rehabilitations. Two obturators of the same design except for different bulb heights, were fabricated for each of the maxillectomy patient. After two months of alternate use, the functions of the obturators were measured by investigating the patients’ subjective evaluations in terms of convenience, speech, nasality, leakage, and mastication and identifying their preferred prostheses. Wilcoxon signed rank test was used as a statistical method (P < .05). Results: There were no significant differences in patient evaluations of low and high bulb obturators (P >.05). And patients’preferences varied. Conclusion: In extreme situation such as in mouth opening limitation, the use of low bulb obturators can be recommended and result in comparable speech function to that of obturators with high lateral walls.
