A digital dental aesthetic restoration method

Abstract

The invention provides a digital oral aesthetic repair method, and particularly relates to a method for designing dental crown veneers for patients. The digital oral aesthetic repair method includes following steps: acquiring face smile digital images and an intraoral tooth crown three-dimensional digital model of a patient; utilizing the face smile digital images to acquire a two-dimensional digital aesthetic design list; mutually overlapping the two-dimensional digital aesthetic design list and the intraoral tooth crown three-dimensional digital model through three-dimensional point cloud digital splicing technology; adding a standard three-dimensional tooth crown veneer digital model into a corresponding position in the intraoral tooth crown three-dimensional digital model; performing deformation adjusting on the standard three-dimensional tooth crown veneer digital model according to the two-dimensional digital aesthetic design list to acquire a three-dimensional digital model of a tooth crown veneer designed for the patient. The three-dimensional digital model is mainly applied in oral implanting, orthodontics and aesthetic repair, can simulate repair effect of the patients before operation and guide work of doctors and technicians during operation and is a quite effective tool for communication between doctors and patients, between doctors and between doctors and technicians.

Description

technical field [0001] The invention relates to a digital oral aesthetic restoration method, in particular to a method for manufacturing an oral all-ceramic restoration by using a digital aesthetic analysis and design method. Background technique [0002] The traditional oral all-ceramic restoration process is often like this: after the restoration doctor sees the patient, after a brief discussion, he will prepare the tooth, take the impression, and then send the model to the production room, let the technician make the restoration according to the condition of the model, and finally The doctor places the restoration in the patient's mouth. This restoration process has many disadvantages in cases of aesthetic restoration: 1) Technicians cannot directly refer to various aesthetic information of the patient's detailed face and oral cavity when making restorations; 2) Physicians do not have one-to-one transfer in the clinical restoration process Design parameters to guide the ...

Problems solved by technology

This restoration process has many disadvantages in cases of aesthetic restoration: 1) Technicians cannot directly refer to various aesthetic information of the patient's detailed face and oral cavity when making restorations; 2) Physicians do not have one-to-one transfer in the clinical restoration process Design parameters to guide the preparation of the restoration space and the treatment of the gingival shape; 3) The aesthetics of patients vary greatly, and the shape and color of the restoration that the physician and technician are satisfied with may not satisfy the patient; 4) It is difficult to guarantee the aesthetic effect of the final restoration, which may easily cause aesthetic problems. Restoration failure and doctor-patient disputes

Since the evaluation is more mature in the two-dimensional direction (X-axis and Y-axis), the standard of spatial evaluation in the Z-axis is more difficult to be precise

In addition, at present, DSD cannot design accurate tooth shape, especially three-dimensional shape
