Embodiment Construction

[0039] The present invention provides a digital design method for dental crown veneer. In order to make the purpose, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] See figure 1 , figure 1 It is a flow chart of the steps of the digital design method of the dental crown veneer of the present invention, and the digital design method of the dental crown veneer comprises the following steps:

[0041] Step S10, acquiring the three-dimensional model data of the dental crown in the patient's mouth through the intraoral scanner. The intraoral scanner uploads the three-dimensional model data to the host. It is convenient for the designers in the laboratory to design the de...

Abstract

The invention discloses a digital designing method of a dental crown veneer. The digital designing method includes the steps: A, acquiring three-dimensional model data of a dental crown in the mouth of a patient through an intraoral scanner; B, acquiring a smile image when the patient opens his or her mouth and a dental crown image when the patient opens his or her mouth fully; C, converting the two-dimensional smile image into a three-dimensional image through 2D-to-3D software; D, combining the three-dimensional model data with the three-dimensional image to form a 3D model when the patient smiles; E, designing a patient smile curve on the dental crown image; F, according to the patient smile curve and the 3D model, designing a virtual dental crown veneer, and stacking the virtual dental crown veneer at a corresponding position of the smile image. By the method, the dental crown veneer is pre-designed, simulative wearing trials are performed, and the patient can see expected effect before restoration of the dental crown; a dental crown restoring scheme can be adjusted according to preference of the patient, and after the restoring scheme is confirmed by the patient, the dental crown veneer can be made according to the confirmed scheme, so that the circumstance that the patient is not satisfied with the effect is avoided.

Description

technical field [0001] The invention relates to the technical field of dental crown veneer design, in particular to a digital design method for dental crown veneer. Background technique [0002] When the patient's crown is partially lost, it is usually compensated by using a crown veneer on the retained crown, so as to achieve the effect of crown restoration. However, this crown restoration method is unpredictable. Only after the crown veneer is finally bonded to the patient's crown can the patient see the restoration effect. If the patient is not satisfied with the restoration effect, the crown veneer needs to be pried again Next, perform secondary bonding. In other words, patients cannot predict the effect after repair before repair. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the deficiencies in the prior art above, the present invention provides a digital design method for dental crown ven...
