초록
이 연구의 목적은 부정교합 모델을 적용한 프로토타입 가상현실(Virtual Reality, VR) 시뮬레이션을 개발하고, 치과 전공의와 치과대학생 간의 수행 결과 및 만족도 설문 비교를 통해 VR 시뮬레이션의 치의학 교육에의 응용 가능성을 평가하는 것이다. 참가자들은 가상 부정교합 모델을 관찰한 후 부정교합의 유형을 진단하고, 가상 부정교합 모델에 나타나는 임상 소견과 적절한 치료계획을 결정하는 세 가지 과제를 수행하였고, 총 5문항으로 구성된 만족도에 관한 설문을 작성하였다. 전공의 집단의 부정교합 평가에 관한 수행능력은 학생 집단과 비교해 유의하게 높았으며(p < 0.01), 두 집단 모두에서 첫 번째 증례를 수행하는 시간보다 두 번째 증례를 수행하는 시간이 유의하게 감소하였다(p < 0.01). 만족도 설문에서는 모든 문항에 대해 보통 이상의 긍정적인 반응을 보였다. 추후 VR 시뮬레이션의 지속적인 개발이 이루어진다면 가치 있는 교육 도구로 응용될 수 있을 것이다.
Abstract
The purpose of this study was to develop prototype of virtual reality(VR) simulation with malocclusion models and evaluate its applicability. Task abilities, task completion time, and a satisfaction survey were compared between dentist trainees and dental students. Participants were instructed to observe virtual malocclusion models and then performed three tasks to diagnose the type of malocclusion, determine clinical findings and develop treatment plans. Their satisfaction with the simulation experience were evaluated using a questionnaire containing five questions. Task abilities of trainees related to clinical features and treatment plans were significantly higher than that of students(p < 0.01). In both groups, the task completion time for the second case was significantly reduced compared to that for the first case(p < 0.01). The satisfaction survey showed high scores and positive responses for this simulation in both groups. If the prototype of VR simulation is continuously advanced, it will be applicable for orthodontic education in pediatric dentistry.
