Embodiment 1

[0024] A denture processing technology utilizing a resin working model, comprising the following steps:

[0025] (1) Perform an intraoral scan on the patient to form three-dimensional image data including the condition of missing teeth in the oral cavity;

[0026] (2) carrying out working model design and missing tooth design according to the obtained three-dimensional image data, and then using a resin 3D printer to print the resin working model; the material of the resin working model is light-cured resin;

[0027] (3) Import the data obtained from the missing tooth design completed in step (2) into the 3D printing device, add metal materials to print the metal inner crown, and complete the production of the metal inner crown; the metal materials are cobalt, chromium, molybdenum and tungsten The metal powder is mixed metal powder according to the mass ratio of 61:27:6:6;

[0028] (4) The metal inner crown printed in step (3) is subjected to conventional porcelain treatment,...

Embodiment 2

[0031] A denture processing technology utilizing a resin working model, comprising the following steps:

[0032] (1) Perform an intraoral scan on the patient to form three-dimensional image data including the condition of missing teeth in the oral cavity;

[0033] (2) carrying out working model design and missing tooth design according to the obtained three-dimensional image data, and then using a resin 3D printer to print the resin working model; the material of the resin working model is light-cured resin;

[0034] (3) importing the data obtained from the missing tooth design completed in step (2) into the five-axis linkage digital cutting equipment to directly cut the zirconia inner crown to complete the production of the all-ceramic inner crown;

[0035] (4) subjecting the all-ceramic inner crown produced in step (3) to conventional porcelain treatment, and then repeatedly trying on and adjusting it on the resin working model printed in step (2);

[0036] (5) firing the a...

Abstract

The invention belongs to the technical field of dental restoration, and particularly relates to a processing process for a denture by using a resin working model. The process includes the following steps: (1) performing intraoral scanning on a patient to form three-dimensional image data including missing teeth in an oral cavity; (2) performing working model design and missing teeth design basedon the obtained three-dimensional image data, and printing the resin working model by using a resin 3D printer; (3) preparing an inner tooth crown by using the data obtained by the missing tooth design completed in the step (2); (4) performing porcelain treatment on the inner tooth crown prepared in the step (3), performing repeated wearing and repeated adjustment on the resin working model printed in the step (2); and (5) firing the adjusted denture at high temperature, performing morphological modification, performing refined modification, and performing glazing to obtain the denture. The denture prepared by the process provided by the invention has higher precision, low costs, a simple process and good patient compliance.

Description

technical field [0001] The invention belongs to the technical field of oral restoration, and in particular relates to a denture processing technology using a resin working model. Background technique [0002] To restore normal chewing function after tooth loss, dentures must be installed. If you want to make a beautiful and comfortable denture quickly and without error, it takes at least 5-7 days to complete from impression taking, production to installation, but this is still the estimated time for a single tooth in the best case. If the sampling data of the dental model in the early stage is inaccurate, and the shape, color, etc. of the denture produced do not match the patient's oral condition, repeated rework and modification are required during the installation process, and a lot of time is wasted during this period. Therefore, the focus of solving this problem lies in the accuracy of the pre-dental mold making and the accuracy of the dentures made according to the den...
