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.
