Embodiment Construction

[0024] The present invention is a kind of three-dimensional dental prosthesis in vitro grinding repair testing machine, this testing machine ( figure 1 ) includes four columns 1, which are rigidly connected with the lower base plate 17 and the upper top plate 11, and they form a frame. The size of the rack is small, its length, width and height are: 300×250×250mm. The upper top plate and the lower bottom plate have a high degree of parallelism, thus ensuring that the 3D CNC workbench can run precisely according to the established requirements. 3D CNC coordinate table ( figure 2) consists of three numerically controlled workbenches with the same structure: a workbench 6 capable of moving left and right in the X direction, a workbench 7 capable of moving forward and backward in the Y direction, and a numerical control workbench 9 capable of moving up and down in the Z direction, and the axes of the three workbenches are in the The space is distributed vertically. Each workbe...

Abstract

The disclosed tester comprises a frame with four posts, bottom plate with a dynamometer, an accommodate-liquid pan, a clamp bottom plate, and a clamp; the top plate with a lock right angle plate and right plate; a 3D digital-control operation platform with X-direction connected to dentistry hand piece, Y-direction and Z-direction platforms every with a straight line slipway of ball screw gear connected to platform motor. This invention fits to fine repair and on-line monitor.

Description

technical field [0001] The invention relates to a three-dimensional dental prosthesis external grinding and repairing simulation test machine, which belongs to the external grinding and repairing device for prosthetics in the field of dental prosthesis. Background technique [0002] Since the application of CAD / CAM technology in the field of prosthodontics in the 1970s, the computer-aided design and manufacturing technology of dentures has developed rapidly. At present, more than 10 related products have been sold in the market abroad. In recent years, some domestic scholars have begun to pay attention to CAD / CAM technology for oral restoration. Researchers such as Lu Peijun of Peking University Stomatological Hospital have initially developed my country's first independent intellectual property rights for oral restorations (crowns, bridges, inlays, etc.) Computer-aided design and manufacturing experiment system [1-2]. Tianjin University and the School of Stomatology of Tian...
