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

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings, see figure 1 and figure 2 .

[0021] The first step is to obtain the 3D face smile model and the 3D face opening model.

[0022] 1) The first step is to improve a fast 3D scanner device disclosed in Chinese patent 201720353413.7, and place a high-resolution (color camera greater than 2 million pixels) texture camera 2 next to the left and right cameras. The purpose of the texture camera is to shoot Oral texture map, because the small field of view only captures the texture of the oral cavity, so the texture is relatively clear and realistic. This texture is used to attach to the teeth model in the mouth of the 3D human face. Two shots were taken, the first shot was used to generate a 3D face smile model (a 3D model of a person photographed and reconstructed in a smiling state), and the second shot was used to generate a 3D face opening model (with the aid of a medi...

Abstract

The invention discloses a tooth aesthetic design method and device. In the method, a three-dimensional human face smile model and a three-dimensional human face opening model are quickly acquired through a three-dimensional scanning device. Doctors can realize on-site communication between doctors and patients by designing dental restorations on the 3D model. Patients can browse the 3D model of their teeth after restoration, which is more realistic and reliable. At the same time, the design can be modified at any time through doctor-patient communication. Since the design parameters of the three-dimensional design can be directly used for processing and making diagnostic veneers in dental aesthetic restoration, the link of diagnosing wax-up in dental aesthetic restoration is omitted. The tooth model printed according to the design can be scanned by a desktop scanner and its three-dimensional digital model can be directly placed in the mouth of the face model, which is convenient for doctor-patient communication. After there is no problem in the doctor-patient communication, the tooth beauty can be completed according to the design parameters such as tooth preparation and porcelain veneer.

Description

Technical field: [0001] The invention belongs to the field of medical cosmetology, and relates to a three-dimensional oral aesthetic design method, which is a three-dimensional dental aesthetic design method. 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 can intuitively see the effect of repair; in addition, DSD ca...
