Problems solved by technology

However, the above work is limited to the field of materials science, and the experimental data are obtained in a static or quasi-static environment, so there is still a big gap in the clinical practice of guiding oral restoration

Embodiment Construction

[0020] The present invention is an in vitro simulation testing machine for dental grinding restoration. The testing machine (FIG. 1) includes a lower bottom plate 16 and an upper top plate 10, and four columns 1 are rigidly connected with the upper top plate and the lower bottom plate respectively. The parallelism of the upper top plate and the lower bottom plate is relatively high, thereby ensuring that the parallelism of the two-dimensional numerical control workbench 8 during operation can meet the requirements of the test. The two-dimensional numerical control coordinate workbench 8 (Fig. 2) includes two linear slides 81 and 83 driven by ball screw pairs, the upper top plate 10 is rigidly connected to the linear slide 81, and the two linear slides are vertically intersecting in space. And each linear slide table lead screw is respectively provided with sliding blocks 82, 84, and two servo motors are respectively connected with two linear slide tables, and the linear motion ...

Abstract

A 2-freedom external simulation tester for grinding and repairing the oral material (tooth material) is composed of a machine frame consisting of 4 vertical posts, bottom plate and top plate, force meter, liquid collecting tray, base plate of fixture, workpiece fixture, the straight-line slipway connected to said top plate and driven by motor or manual roll-screw set, another slipway perpendicular to the screw of the first slipway, a height regulator, and a clamper linked with the dental handware.

Description

technical field [0001] The invention relates to an in vitro simulation test machine for grinding and repairing oral materials with a two-dimensional degree of freedom, which belongs to an in vitro simulation device for grinding and repairing oral materials. Background technique [0002] In the field of prosthodontics, the use of high-speed dental handpieces for oral prosthetics to adjust the occlusal relationship between the prosthetics and the teeth is a key technical problem in prosthodontics. The difficulties include: the complexity of the oral environment, the difficulty of prosthetic removal, It is very easy to produce grinding repair damage, which leads to early micro-damage and sudden macro-destruction of the restoration, as well as the discomfort caused by dynamic cutting force, vibration and noise to the patient. For a long time, the dental restoration process can only rely on the experienced and qualitative judgment of the dentist and the clinical feeling of the pa...
