최근 임프란트 무치악의 재건을 위해 많이 사용되어 지고 있으며, 그 성공률은 환자의 전신적 건강 상태, 임프란트 재료의 생체 적합성, 술자의 술식, 골의 질 과양에따라좌우된다1).“ bone quantity"는임프란트 식립시 유용한 골의 양을 나타내고 ”bone quality"는 골의 생리, 광화작용의 정도 등의 다양한 면을 종합적 으로 평가하는 용어이다.
Purpose : To evaluate density of alveolar bone of the maxilla and the mandible on DICOM images(V Implant software) and compare with the bone quality of during installed implant. Materials & Methods : Thirty-three implant sites of thirteen patients were selected, and bone quality was measured with V implant imaging software(Cybermed, Seoul, Korea). Objective scale of the bone density based on the Hounsfield unit and evaluation of correlation between bone density value and subjective quality score when implant was installed. Results : Mean density of Hounsfield unit of Upper anterior area was 266.3 HU, upper posterior area was 166.1 HU, lower anterior area was 462.1 HU, lower posterior area was 418.3 HU. Mean Hounsfield units according to bone quality was Q1-496.9 HU, Q2-306.25HU, Q3-184.14HU, Q4-37.0HU. Conclusion : Measurement of Hounsfield unit can be helpful as a valuable supplement to bone density evaluation before implant installation.
