Abstract

Occlusal plane is a sagittal expression of dental arch form, and it composes the shape of occlusion, which is one of the most important elements of Maxillo-oral system. In this case, vertical, horizontal coordinates of bionic-median-sagittal plane was produced in articulator, and to achieve relation of left and right position of upper, lower teeth and deficits in alveola, Shilla system was used to reconstruct occlusal plane. In this case, a 41 year-old male patient visited for fracture of 10 unit metal-ceramic fixed partial denture of upper anterior teeth and for overall treatment. Clinical, radiographical, model examination was held, full mouth rehabilitation was achieved by placing dental implant. Maxillo-oral relation was recorded using Gothic arch Tracer complex and were mounted. And for the next step, we estimated original occlusal plane using Shilla system. After analysis we produced diagnosis wax pattern. On the basis of this, radiography stent was manufactured and dental implant was placed, and temporary prosthesis was made by using diagnosis wax pattern. Cross mounting and anterior guiding table were performed in order to reproduce temporary restoration morphology and bite pattern, followed by final restoration made of all ceramic crown with zirconia coping. As stated above, appropriately esthetic and functional results can be seen in using Shilla system in diagnosis and treatment procedure of full mouth rehabilitation patient.

교합평면은 시상면적인 치열궁 형태를 나타내는 것으로, 악구강계를 구성하는 요소의 하나인 교합을 형태적으로 구성한다. 본 증례에서는 생체의 정중 시상면에 대한 수평, 측방좌표를 교합기상에 재현하여 상하악 치아 및 결손부 치조제에 대한 좌우 동적인 위치관계 얻기 위해 Shilla system (Hamans, Tokyo, Japan)을 이용하여 교합평면을 재구성 하였다. 본 증례의 환자는 41세의 남자 환자로 상악 전치부 10본금속-도재 고정성국소의치 파절 및 탈락과 전반적인 치료를 주소로 내원하였다. 임상 검사, 방사선 검사, 모형분석을 통해 임플란트 식립을 동반한 완전구강회복술을 하기로 결정하였다. Gothic Arch device (Centrofix; AmannGirrbach GmbH, Germany)를 이용하여 악간관계를 채득하고 마운팅 후, Shilla system을 이용하여 기존 교합평면을 평가, 분석하여 진단 납형을 제작하였다. 이를 토대로 방사선 스텐트를 제작하여 임플란트 식립하였고, 진단 납형을 이용하여 임시수복물을 제작하였다. 임시 수복물의 형태 및 교합 양식을 재현하기 위해 맞춤 전방유도판을 제작하고, 교차 마운팅을 시행하였으며 최종 수복물은 지르코니아 코핑을 이용한 완전 도재관으로 제작하였다. 이상과 같이 전악수복환자에서 진단과 치료 과정에서 Shilla system을 이용하여 적절한 심미적, 기능적 수복 결과를 얻을 수 있었다.
