Embodiment Construction

[0015] A method of fully digitally customizing a dental restoration comprising the steps of:

[0016] S1: Scan the inside of the patient's oral cavity. The intraoral scanner uses a dual-camera device; when the scanner scans, the two cameras take pictures of the teeth respectively, according to the fixed distance between the two cameras and the angle between the camera and the teeth to be photographed , the computer automatically calculates the distance between the scanner and the tooth and the actual size of the scanned tooth;

[0017] S2: The occlusal model is cut out through CAD / CAM, and then the doctor adjusts the shape of the occlusal surface under the occlusal movement of the patient's teeth, so as to establish an accurate and suitable occlusal relationship between the upper and lower teeth;

[0018] S3: Install the try-in tooth in the cavity and perform the second scan;

[0019] S4: During the scan, the occlusal surface of the try-in teeth and their dentition and the oc...

Abstract

The invention relates to the field of dental customization and in particular relates to a method for completely digitally customizing dental restoration. The method comprises the following steps: scanning an oral cavity, performing color comparison, printing a try-in tooth, scanning the try-in tooth, and determining final dental restoration. The method is simple in step, and final dental restoration can be obtained by digital means.

Description

technical field [0001] The invention relates to the field of dental customization, and more specifically, relates to a method for completely digitally customizing a dental restoration. Background technique [0002] In the process of digital dental restoration, after intraoral scanning, the final restoration is usually only made by simple software fine-tuning. When the final restoration is tried-in and bonded, it often needs to be ground again. At the same time, the current technology still uses part of the digital technology, it is difficult to leave the manual production process, it is impossible to achieve complete digital production, and the accuracy cannot be guaranteed. In the present invention, through the complete digital technology, after intraoral scanning and before the final prosthesis is made, the tooth occlusal model is made through CAD / CAM. After trying on the model, it is found that the original design is unreasonable, and it is simply adjusted and scanned. 3...
