Embodiment 1

[0088] Such as figure 1 As shown, a dental full crown preparation device includes a frame, which is equipped with a motor, a control mechanism for controlling the operation of the motor, a cooling system, and an annular grinding and cutting belt driven by the motor. The grinding and cutting belt includes a smooth Surface and grinding surface with emery.

[0089] When in use, put the grinding and cutting belt of the present invention on the teeth to be treated, the grinding surface is in contact with the teeth to be treated, then the control mechanism is operated, the motor is started to drive the grinding and cutting belt to rotate, the grinding surface quickly grinds the teeth, and during the grinding process The cooling system will also cool the grinding surface and grinding debris in time. During the processing, the grinding surface is in contact with at least three axial surfaces of the teeth to be treated. Grinding the circumferential contour, the invention can not only ...

Embodiment 2

[0119] The only difference from the first embodiment is that the cross-section of the axial grinding strip is tapered with a wide top and a narrow bottom, and the taper is 6°.

Abstract

The invention discloses a device for preparing dental corona. The device comprises a frame, wherein a motor, a control mechanism and an annular abrasion cutting belt are arranged on the frame; the control mechanism is used for controlling the motor to run; the annular abrasion cutting belt is driven by the motor; and the annular abrasion cutting belt comprises a smooth surface and a polishing surface with emery. The device for preparing dental corona has a simple structure and is convenient and practical.

Description

technical field [0001] The invention relates to a dental full crown tooth body preparation device. Background technique [0002] The full crown is the most common restoration in the Department of Prosthodontics. It covers the entire surface of the crown and can be used to restore the shape, function and appearance of the missing tooth. It can also be used as a retainer for fixing the denture. The etiology of the tooth defect is Caries, trauma, wear, acid erosion and developmental deformities are common and frequently-occurring diseases in stomatology; if the defect is too large, a full crown restoration is required. [0003] The following is a porcelain crown as an example to illustrate the process of the crown: [0004] 1. Oral preparation [0005] Reshape the cusps and marginal ridges of adjacent teeth and opposing teeth that are too sharp, too long, or have abnormal shapes that hinder restoration. [0006] 2. Tooth preparation [0007] ①Preparation of the lingual surf...
