COMPUTERIZED EVALUATION OF OCCLUSAL CONTACTS IN CENTRIC CLOSURE IN DISTAL EXTENSION PARTIAL DENTURE CASES

유리단 국소의치 환자에서 T-scan system을 이용한 중심교합시에 교합접촉 양상 연구

This clinical study was to analyze occlusal contacts in maximum intercuspation on distal extension partial denture and to compare tooth contact state between the denture teeth and abutment teeth by time mode and force mode using the T-scan system. The subjects ware twenty-one adult patients with upper natural teeth and lower distal extension partial denture. Conclusion : 1. The patient with simultaneous occlusal contacts both denture tooth and abutment and bilaterally in Kennedy Class I cases was one-sixth, but there was no one with symmetric occlusal and equal force among bilateral denture teeth and abutments. 2. The five-fifteenth of Kennedy Class I case patients resulted in simultaeous occlusal contacts bet-ween denture teeth and abutments but no one has the symmetric occlusal contacts and unifarm force between denture teeth and abutment teeth.
