Abstract

In a case of class III skeletal patients with severe alveolar bone resorption, it must be a complete denture treatment plan provided stable and durable occlusion. Despite a markedly increased tooth mobility and unfavorable crown-to-root ration due to periodontal tissue breakdown, if the inflammatory process is controlled and an adequate oral hygiene performed, fixed splints will be considered. Patient's discomfort will be eliminated by achievement better clinical tooth mobility using fixed splints. So it can be a cost and time effective treatment option. In this case, it used a T-Scan System for confirmation a bilateral balanced occlusion and a occlusal force distribution reflected a patient's functional mandibular movement.

심한 치조골 흡수를 동반한 III급 악골 관계 환자의 총의치 제작의 경우 안정적이고 지속적인 교합을 제공하는 치료계획을 세워야 한다. 불리한 치관 대 치근 비와 임상적 동요도가 관찰되는 하악 잔존치를 고정하여 사용함으로써 환자의 불편감을 줄이고 시간적, 경제적으로 효율적인 치료를 제공할 수 있다. 본 증례에서는 상악 편악 무치악 환자의 기능적인 하악 운동과 조화로운 총의치 균형 교합을 이루기 위해 T-Scan System을 이용하였다.
