초록
최근 디지털 치의학 기술이 치과 치료에 다양하게 활용이 되고 있다. 본 증례는 다수의 치아 상실과 치아 마모로 수직고경이 감소한 환자의 치료에서 이러한 디지털 치의학 기술이 어떻게 적용되는지 다루고 있다. 감소한 수직고경을 주의 깊게 평가하여 회복하였고, 최종 수복물을 고려하여 설계한 수술용 가이드를 이용하여 임플란트 식립을 시행하였다. 디지털 악간관계 측정기를 이용하여 하악의 전측방 운동을 측정하여 교합기에 반영하였고, Naturgemäße Aufwachs-Technik (N.A.T.), Natural functional reconstruction (N.F.R.)을 이용한 왁스업 과정을 진행하였다. 이를 스캔하여 CAD/CAM 기술로 임시 수복물을 제작하였고, 기능적, 심미적으로 만족스러운 상태까지 진료실에서 조정과정을 거친 뒤 Computer-Aided-Design/Computer-Aided-Manufacturing (CAD/CAM) 기술을 활용하여 최종 수복물로 그대로 이행될 수 있도록 하였다. 이와 같이 디지털 치의학 기술과 전통적인 방식의 장점을 활용하여 환자와 술자 모두 만족할만한 결과를 얻었기에 이를 보고하고자 한다.
Abstract
As digital dentistry technology is being developed, it is being used in various ways. This case covers how digital dentistry technology is being applied on the treatment of patients with loss of vertical dimension due to worn dentition and multiple loss of teeth. The loss of vertical dimension was carefully assessed and recovered, and implants were placed with surgical guides, designed considering the final restoration. The movement of the mandibular was measured with the electronic instrument for recording mandibular movement. Wax-up process was done with Naturgemäße Aufwachs-Technik (N.A.T.) and Natural functional reconstruction (N.F.R.). It was scanned, and the provisionalrestoration was fabricated using Computer-Aided-Design/Computer-Aided-Manufacturing (CAD/CAM) technology, and the adjustment process was done at the clinic to meet with the satisfaction both functionally and esthetically, and then, using double scanning and CAD/CAM technology, it was carried out as a final restoration. As a result, the patient obtained satisfying results, utilizing the benefits of digital dentistry technology and traditional methods.
