Problems solved by technology

However, the operation process of the facebow and the mechanical articulator is very complicated, and improper operation will lead to wrong results. Moreover, for patients, the facebow is placed on the occlusal fork in the mouth at the level of the locator of the external auditory canal and the bridge of the nose. It will bring discomfort and even pain to patients, so it is often omitted in daily clinical treatment

Embodiment Construction

[0020] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0021] A method for intelligently digitizing a prosthetic crown, comprising the following steps:

[0022] Step 1: Obtain the patient's upper and lower dentition, missing position, gums and occlusal relationship data through a hand-held scanner, and obtain the matching color of the patient's teeth through a colorimeter, standard color guide and computer intelligent color comparison, and obtain tooth photos at the same time , and obtain a 3D full-color image of the patient's oral cavity through handheld scanning, and upload it to the cloud at an image ratio of 1:1 with the oral data, which is convenient for the installation simulation after the crown design is completed.

[0023] Step 2: Obtain 3D...

Abstract

The invention discloses a method for intelligently and digitally manufacturing a substituted crown, oral cavity data of a patient and jaw bone and tooth root data are quickly obtained in a 3D scanning mode, the data are quickly integrated and matched with design software in a cloud uploading mode, a designer can quickly design on the design software according to cloud data, docking with a clinician is implemented at the cloud end, a design scheme and a treatment scheme are rapidly obtained, meanwhile, the substituted crown installation process is repeatedly simulated, and the discomfort of the clinician when the substituted crown is worn by a patient is reduced.

Description

technical field [0001] The invention relates to the field of making dental restorations, in particular to an intelligent digital method for manufacturing crown replacements. Background technique [0002] Dental restorations are restorations made of artificial materials that meet the physiological functions. They must be highly matched with the remaining teeth of the patient’s mouth and highly coordinated with the muscles and joints in order to restore normal oral functions, especially masticatory functions. Dental technicians usually base on a The gypsum model of the dentition of the auxiliary patient is used to make restorations, which can only reflect the relationship between the upper and lower dentition in the static centric position. Fang et al simulated chewing and grinding to make the dental restoration adapt to the physiological function and the patient felt comfortable. The trial-in and grinding of the restoration not only takes a long time, but the patient’s comfor...
