Abstract

A patient with para-functional habits can cause widespread teeth wear, along with temporomandibular joint disorders and myofascial pain syndrome in the masticatory muscles. Prolonged teeth wear is associated with a decrease in vertical occlusal dimension, leading to issues such as changes in facial morphology, decreased masticatory efficiency, and temporomandibular joint disorders. To achieve a three-dimensional full-mouth rehabilitation in patients with decreased vertical occlusal dimension, accurate diagnosis, analysis, and proactive treatment planning are essential. Prosthetic treatment accompanied by the restoration of physiological vertical occlusal dimension and the re-establishment of a normal occlusal plane is necessary. This case report presents a full-mouth rehabilitation case involving a patient with overall teeth wear, showing decreased vertical occlusal dimension which results in discomfort in the temporomandibular joint and aesthetic dissatisfaction. The report highlights the successful outcome achieved through the use of occlusal stabilization splint for temporomandibular joint stability and Gothic arch tracing devices for the re-establishment of intermaxillary relationships. Also, through adjustments and adaptation assessment using provisional prostheses, favorable outcomes were achieved both functionally and aesthetically.

비기능적 습관을 가진 환자는 턱관절 장애, 저작 근육의 근막통증증후군 등과 함께 치아의 광범위한 마모를 유발한다. 지속되는 교모는 수직교합고경의 감소를 동반하게 되며 이는 안모의 변화, 저작 효율 저하, 측두하악 관절 장애 등의 문제가 발생할 수 있다. 이런 수직교합고경 감소 환자의 3차원적인 교합 회복과 재구성을 위해서는 정확한 진단 및 분석과 예지성 있는 치료계획 수립이 필요하며, 생리적인 수직교합고경의 회복 및 정상적인 교합평면 재설정을 동반한 보철치료가 필요하다. 본 증례는 구강 악습관에 의한 전반적인 치아의 마모와 저작근의 불편감, 그리고 수직교합고경 감소로 인한 심미적 불만족을 호소하는 환자의 수직교합고경 증가를 동반한 완전 구강 회복 증례이다. 교합안정장치를 통한 측두하악관절의 안정과 고딕아치 기록장치를 이용한 악간관계 재설정 및 임시 수복물을 통한 경과 관찰을 통해 기능적, 심미적으로 좋은 결과를 보였기에 이를 보고하고자 한다.
