Abstract

There are many studies on the indications and efficacy of splint therapy commonly used in patients with temporomandibular disorders (TMD). However, there have been no studies on the splint weaning in terms of the splint use tapering period in relation to symptom improvement of TMD. This retrospective study aims to analyze a proper splint weaning method in patients with TMD based on symptom improvement. Materials and Methods: The authors examined 130 TMD patients with TMJ disorders, masticatory muscle disorders, and clenching/bruxism who had received splint therapy (occlusion stabilization splint, anterior positioning splint) of patients who visited the Department of Orofacial Pain and Oral Medicine at Yonsei University Dental Hospital from 2015 to 2020. They were evaluated according to the method to wean splints. Results: The mean splint therapy period was 29.0 months, during which patients wore splints 7 days a week for 8.4 months, 3 - 4 days a week for 9.5 months, and finally 1 - 2 days a week for 11.1 months (a total of 29.0 months, about 2.5 years). Conclusion: It seems that TMD symptoms can be alleviated and side effects such as occlusal change can be minimized if patients wear a splint 7 days a week for the first 6 months, followed by 3 - 4 days a week for the next 6 to 18 months, and finally 1 - 2 days a week after 18 months.

목적: 측두하악장애 환자에게 주로 사용되는 장치 치료의 적응증 및 효과에 대한 연구는 다수 존재하나, 증상 개선에 따라 장치를 테이퍼링하여 종료하는 방법에 대한 연구는 부족하다. 따라서 본 후향적 연구는 측두하악장애 환자를 대상으로, 증상 개선에 따라 장치를 테이퍼링하여 종료하는 과정을 고찰하고자 한다. 연구 재료 및 방법: 턱관절 질환, 근막 통증, 이갈이 및 이악물기 등을 주소로 연세대학교 치과대학병원 구강내과를 내원하여 장치 치료(교합안정장치, 전방위치교합장치)를 시행한 130명의 환자의 차트 리뷰를 통해 장치 치료를 테이퍼링하여 종료하는 과정을 알아보았다. 결과: 평균 장치 장착 기간은 29개월로, 매일 장치를 장착한 기간은 8.4개월, 일주일에 3 - 4일간 장치를 장착한 기간은 9.5개월, 일주일에 1 - 2일간 장치를 장착한 기간은 11.1개월이었다. 결론: 측두하악장애 환자에서 장치 장착 시 처음 6개월 간은 매일 장착, 이후 6개월에서 18개월 동안은 일주일에 3 - 4일간 장착, 18개월 이후부터는 일주일에 1 - 2일간 장착하는 방식으로 테이퍼링하여 장치 치료를 종료할 시 측두하악장애 환자의 증상은 완화시키면서 교합 변화 등의 부작용은 최소화시킬 수 있을 것으로 사료된다.
