デンタルX-Pによる補綴学的診断 Prosthetic Diagnosis Using Periapical Dental Radiographs for Crown and Bridge
The purpose of this study was to investigate the problem of prosthetic diagnosis using periapical dental radiographs for crown and bridge. In general, periapical dental radiographs were on the following.<BR>1. The form of pulp cavity.<BR>2. The length ratio of crown to root.<BR>3. The form of root trunk.<BR>4. The resorption of root and bone.<BR>5. The dental caries and the root fracture.<BR>6. The structure of periodontal tissue (the space of periodontal membrane, the alveolar border, the lamina dura and the spongy substance of alveolar bone).<BR>The radiographic findings are useful for periodontic and endodontic diagnosis. More useful and functional information must be obtained for prosthetic diagnosis. Thus, the suggested plans are as follows:<BR>1. The crown and bridge made by prosthodontist with a 5-year guarantee.<BR>2. The oral radiologist should administer and manage all periapical dental radiographs.<BR>3. To investigate viewing radiographs from a functional perspective.<BR>4. Practice of prosthetic treatment with team-approach.<BR>Two cases were reported. One was a destruction case of periodontal tissue by ITI implant. The other was a reconstruction case of periodontal tissue by the transplantation of mandibular molar following iliac cancellous bone graft.
