<p>A surveyor device capable of designing a hook and a base and manufacturing a dental prosthesis smoothly detachable and having sufficient stability after installation. The surveyor device comprises a base table (2), a model receiving table (3) for setting a tooth form model thereon, a model receiving table support means (4) for supporting the model receiving table on the base table after angular adjustment and setting, and a surveying line marking means (5) for marking a surveying line on the tooth form model on the model receiving table. The model receiving table support means comprises a V-axis rotating table (8) rotatably supported on a first rotating shaft (6) extending vertically to the base table and pivotally supporting a V-axis (7) extending parallel with the base table, an X-Y axis table (10) rotatably supported on the V-axis and having a second rotating shaft (9) crossing perpendicularly to the V-axis, an X-Y axis rotating table (12) pivotally supported on the second rotating shaft and having an X-axis (11) crossing perpendicularly to the second rotating shaft, a Y-axis base table (14) pivotally supported on the X-axis and having a Y-axis (13) crossing perpendicularly to the X-axis, and a model receiving table support plate (17) connected by a universal joint mechanism (16) extending radially from the shaft body (15) of the Y-axis.</p> |
