고정성 분할 브릿지의 연결 어태치먼트

다국어 초록 (Multilingual Abstract)

There are some cases that dental prosthesis does not operate as properly as expected in oral mouth. The reasonsare such as a distortion of the mandibular, a fault of impression taking system or an extrusion of remaining teeth.One of dental prostheses to consider in the situations is the attachment which connects segment bridge. Active discussions are managed on theoretical side of this field but few on clinical side of it, which must beconsidered first. Accordingly I'd like to suggest a theoretical background for connect attachment of fixedsegmented bridge.1. As a bridge gets longer, burden on dental ligament is increased and the hardness of a bridge is lessened.2. The flexibility of a bridge increases in ratio to 3 multiplication of the length and decreases in ratio to 3multiplication of the width of occlusal surface and base of pontic.3. Precision rest is needed to cope with the shake of teeth and the difference of axis direction among abutments.4. Female part of the precision rest should be on middle abutment distal and male one on mesial of pontic. 5. Segmented attachment can be efficiently used to cope with long span bridgework and also in case that onepiece casting can't be done because of slant of abutment.
