초록

구치부 교합의 붕괴는 정상적인 교합평면을 소실 시키고, 과도한 마모를 일으켜 수직고경을 감소시킨다. 감소된 수직 고경은 심미적, 기능적 문제를 일으킬 뿐만 아니라 측두하악관절에 과하중을 야기하고 근신경계 이상을 일으킬 수 있다. 이렇게 붕괴된 교합관계를 개선하기 위해서 수직고경 변경을 고려하여야 하는데 치료 전 정확한 진단과 분석이 필수적이며 새로운 수직 고경에 대한 적응 평가를 함께 하여야 한다. 그리고 과도한 수직피개를 가지는 과개교합 환자는 치아 마모 및 치아정출의 교합 문제를 가지는 경우가 많다. 이러한 사항을 고려해 보았을 때 치아마모로 수직고경이 감소된 과개교합 환자의 문제 해결을 위해서는 전반적인 보철수복을 하여야 한다. 본 증례는 68세 남자환자로 다수 치아의 마모와 상악 구치의 결손부위를 치료하기 위해 수직고경 증가를 동반한 상악 가철성 국소의치 및 상하악 고정성 보철물로 수복한 증례이다.

The collapse of the posterior occlusion destroys the normal occlusal plane and causes excessive wear reducing the vertical dimension. Reduced vertical dimension of occlusion causes not only aesthetic and functional problems but also overloading on the temporomandibular joints and abnormalities of muscle nerve system. In order to improve the collapsed occlusal relationship, it is necessary to consider the change of the vertical dimension. It is necessary to make a precise diagnosis and analysis before the treatment and to evaluate the adaption of patient to the new vertical dimension of occlusion. A patient with excessive overbite often has occlusal problems of tooth wear and tooth eruption. Considering these considerations, overall prosthodontic restoration is required to solve the problem. A patient of 68 year old man in this case who suffered major tooth wear and maxillary posterior teeth loss was treated with elevation of vertical dimension of occlusion by maxillary removable dental prosthesis and mandibular fixed prosthesis.
