Problems solved by technology

However, there are many problems in 2DDSD at present. Since the actual 3D size of the designed teeth cannot be obtained in 2D, the rendering after design may not be ideal. It can only be used as a reference for communication between doctors and patients, but it cannot be used for design. Center for direct machining, requires design center to redesign
In addition, the two-dimensional design process is very cumbersome and difficult to learn, and the design is time-consuming

Embodiment Construction

[0025] Attached below figure 2 The present invention is described in detail.

[0026] Step 1: Improve a fast 3D scanner device disclosed in Chinese patent 201720353413.7. figure 1 , a texture camera is placed between cameras 1 and 3 to capture the frontal texture of the face, and the texture is clear and realistic. This texture is used to paste on the 3D face model. The face scanning equipment collects Model 1 and Model 2. Model 1 is the color 3D model scanned when the patient smiles and shows his teeth, which is called the smile model; Model 2 is the color 3D digital model scanned by the patient fully showing teeth and gums with the aid of a mouthpiece. The dental model scanner collects three high-precision three-dimensional dental digital models of the patient, namely model three, model four, and model five. Model three is the three-dimensional digital model of the upper dentition in the occlusal position, model four is the three-dimensional digital model of the lower d...

Abstract

The invention discloses a dental restoration design method and device based on a three-dimensional scanning device. The three-dimensional scanning device quickly acquires a three-dimensional human face model and a patient's high-precision digital three-dimensional model of teeth. Through the matching relationship between the two models, it is registered into the mouth of the face model. At the same time, attach texture to the digital 3D model of teeth in various ways, and then take a single or multiple standard dental models to replace the single or multiple teeth to be repaired. Restoration design is carried out by adjusting standard dental model parameters, and at the same time display the three-dimensional model of the tooth after restoration to realize dental restoration design. The design parameters can be directly used to process and manufacture diagnostic veneers in dental aesthetic restoration, which saves the link of diagnostic wax-up in dental aesthetic restoration and speeds up the entire dental cosmetic design process. The digital smile design based on 3D can overcome many defects of 2D DSD and perfect the DSD design.

Description

Technical field: [0001] The invention belongs to the field of medical cosmetology, and relates to a three-dimensional aesthetic design method for oral cavity, in particular to a dental restoration design method and device based on a three-dimensional scanning device. Background technique: [0002] In recent years, with the continuous and in-depth research on the aesthetic restoration of anterior teeth, dentists believe that design is the starting point and soul of aesthetics, and digital smile design (DSD) technology is currently a relatively cutting-edge means of aesthetic restoration design. The concept of DSD was proposed by Brazilian dentist Coachman and his team. DSD technology is a multi-purpose tool in aesthetic restoration. It uses software such as Keynote, Photoshop, DSS or ezDSDpro to digitally quantify the soft and hard tissues of the patient's face and oral cavity. With accurate analysis, design and digital simulation of treatment results, doctors and patients ca...
