Abstract

Although not all kinds of deep bite occlusions are considered pathological states, they can cause persistent wear and eruption of the anterior mandibular teeth if the anterior occlusal contact is unstable or accompanied by an occlusal disharmony. The patient was a 72-year-old man with no occlusal contact of the remaining anterior teeth in the centric relation position because of a skeletal class II malocclusion and loss of occlusal support. If the vertical dimension needs to be increased for prosthetic restoration in a patient with a deep bite, the amount of vertical dimension increase must be determined through precise diagnosis. This is because the overjet may increase and cause an unstable occlusion. In this review, we report the case of a patient with a stable occlusion and good treatment results achieved by using a removable partial denture prosthesis and applying the Dahl concept.

모든 과개교합을 가진 환자를 병적인 상태로 판단할 수는 없지만 전치부에 교합접촉이 불안정하거나, 전반적인 교합 부조화가 동반된다면 과개교합은 하악 전치에 대한 지속적인 마모와 정출을 일으킬 수 있다. 이 증례는 72세 남성환자로 상악과 하악의 전치가 잔존해 있지만 골격성 2급 부정교합으로 인하여 안정위 상태에서 교합접촉이 불가능하고 교합지지가 완전히 상실되어 수직고경의 증가가 필요한 환자였다. 이 증례는 보철 수복을 위해 수직고경의 증가가 필요한 경우로 수평피개를 더욱 심화시켜 교합의 부조화를 유발할 수 있기에 정밀한 진단을 통한 수직고경 증가량 결정이 필요하였다. 이 증례에서는 Dahl concept를 응용한 가철성 국소의치 보철물을 이용하여 안정적인 교합을 완성하였으며 적절한 치료 결과를 보였기에 이를 보고하고자 한다.
