Embodiment 1

[0037] figure 1 A schematic flow diagram of a digital oral restoration method provided by Embodiment 1 of the present invention, as figure 1 As shown, the method includes the following steps:

[0038] 101. Obtain three-dimensional data of the target position by using an intraoral scanner.

[0039] Specifically, when the tooth is damaged or missing, the tooth needs to be repaired, and currently people have high requirements for the beauty of the tooth and the comfort of the restored tooth, so it is necessary to carry out accurate restoration of the tooth. To meet the above needs, an intraoral scanner can be used to obtain the three-dimensional data of the target position. For example, when a certain tooth is damaged or missing, the position of the tooth can be used as the target position, and the three-dimensional data at the position can be obtained according to actual needs. Through the three-dimensional data, the specific parameters of the place can be accurately grasped, ...

Embodiment 2

[0047] In a feasible embodiment, the target location includes: the target tooth crown and bone tissue in an edentulous implant area.

[0048] Specifically, when only part of the crown is incomplete, the conventional repair method can be used. At this time, only the real part of the crown needs to be repaired, so it is only necessary to collect the three-dimensional data of the target crown. For missing teeth In this case, it is necessary to adopt the method of implant restoration. At this time, the implantation of the tooth root and the bonding of the entire crown are required. When performing root implantation, it needs to be performed on the bone tissue of the edentulous area, so it is necessary to obtain the bone tissue of the edentulous implant area. three-dimensional data.

[0049]In a feasible implementation, when the target position is the target tooth crown, when step 103 is performed, it can be exported to the oral clinical surgery robot according to the driving data ...

Embodiment 3

[0062] In a feasible embodiment, after the preparation of the tooth body and the preparation of the restoration body are completed, the prepared tooth body is put on the tooth body to be restored, so as to complete the oral restoration.

[0063] Specifically, after completing the preparatory operation of the tooth to be restored and the preparation of the restoration, the final restoration of the tooth can be carried out, that is, by blending or bonding, the prepared tooth is put on the tooth to be restored, and the In the embodiment of the present invention, since the preparatory operation of the tooth to be restored and the manufacture of the restoration are carried out in a synchronous manner, it is beneficial to shorten the treatment time of the oral restoration.

[0064] It should be noted that the specific operation of putting the manufactured restoration on the tooth to be restored can be set according to actual needs, and is not specifically limited here.

Abstract

The embodiment of the invention discloses a digital oral restoration method and system. The method comprises the steps of: obtaining three-dimensional data of a target position by using an intraoral scanner; importing the three-dimensional data into a three-dimensional data model of a preparatory body designed by preparatory body designing software to serve as a driving data set; exporting the driving data set to carry out preparatory operation of a to-be-restored tooth; and sending the driving data set to a restoration producing system to carry out restoration production. Compared with a method of asynchronously carrying out the preparatory operation of the to-be-restored tooth and the restoration production in the prior art, the method disclosed by the embodiment of the invention is beneficial to shortening the treatment time, improving the treatment efficiency and reducing the visiting frequency.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a digital dental restoration method and system. Background technique [0002] With the improvement of living standards, people pay more and more attention to the beauty of teeth. When a tooth is missing, the tooth needs to be repaired. Usually, different restoration plans are adopted according to the degree of incompleteness of the tooth. [0003] For example, when only part of the crown is incomplete, conventional restoration methods can be used, such as making an impression of the incomplete crown and preparing the tooth, and then sending the impression to the laboratory for restoration. After the body is made, the doctor will complete the final bonding work; when the tooth is extracted, the implant restoration method can be used, such as making an impression of the toothless area and adjacent area tissue and preparing the implant socket, and then the implant Implantation, ...
