An Aided Design Method for Dental Restoration

Abstract

The invention discloses a dental restoration assisted design method. According to the method, a three-dimensional human face model and a high-precision dental digital three-dimensional model of a patient are quickly acquired through a three-dimensional scanning device; through the matching relationship between the two models, an acquired texture map is attached to the dental digital three-dimensional model and registered into an oral cavity of the human face model; then single or multiple teeth to be repaired are replaced with single or multiple standard dental molds; a doctor performs repairing design on the teeth by adjusting parameters of the standard dental molds to meet the aesthetic design and the patient's requirements; at the same time, the patient can browse the three-dimensionalmodel of his own teeth after restoration, which is more realistic and reliable; the final designed teeth can be printed into solid teeth directly for embossing a female mold; and a medical repair material is poured into the female mold, then the female mold is sleeved on the to-be-repaired teeth of the patient or the teeth after teeth preparation, the female mold is taken out after the repair material is solidified on the teeth, and finally the dental repair assisted design is realized.

Description

Technical field: [0001] The invention belongs to the field of medical cosmetology, relates to a three-dimensional oral aesthetic design method, and is an auxiliary design method for tooth restoration. 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 can also i...

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
