Embodiment Construction

[0025] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but should not be used to limit the scope of the present invention.

[0026] The manufacturing method of the veneer restoration shade guide system of this embodiment comprises the following steps:

[0027] S1. Prepare the veneer on the standard tooth model to form the standard shape of the abutment teeth.

[0028] The right upper central incisor (Nisshin Corporation, Japan) of the standard tooth model was prepared with a veneer tooth preparation set (NTI-Set 1752, NTI-Kahla GmbH, Germany) for standard veneer preparation with a fenestration. 0.3mm, 0.5mm, 0.7mm. Because the tooth preparation of the anterior teeth veneer is prepared according to three parts of the lip, face and neck, the preparation amount of the neck 1 / 3-1 / 2 is small, generally 0.3-0.5mm, and 1 / 2-2...

Abstract

The invention relates to the technical field of dental restoration equipment, and particularly discloses a veneer restoration body colorimetric plate system and a manufacturing method thereof. The method comprises the following steps that veneer preparation is performed on a standard tooth model to form standard-form abutment teeth; a corresponding female die is manufactured according to the standard-form abutment teeth; the female die is filled with resin with different tooth body colors to manufacture resin abutment teeth with different hues, and arranging is performed according to a specified hue sequence; digital images before and after standard tooth model preparation are prepared by using a scanner, and through a copying method, veneers of which the surface forms are consistent withstandard tooth model preparation parts are designed by CAD / CAM computer assistance; and different materials are selected to manufacture veneers, and arranging is performed in a classified mode according to different materials. The method can be consistent with clinical practice, the influence of porcelain materials, adhesive hues and abutment tooth colors on the final aesthetic effect of the restoration body is fully considered, resin abutment tooth and veneer combined color selection is performed, the color of the veneer restoration body is predicted with the optimal effect, and the natural aesthetic effect of affected teeth is recovered.

Description

technical field [0001] The invention relates to the technical field of oral restoration equipment, in particular to a veneer restoration shade guide system and a manufacturing method thereof. Background technique [0002] The matching of the color of the veneer restoration to the natural tooth is one of the main criteria for the success of the restoration. At present, in clinical veneer restoration color comparison, use the restoration color guide (mainly the Vita 3D Master shade guide) to compare the color of the natural tooth, select the target color of the veneer restoration, and how to choose the porcelain material for the doctor or technician , Abutment color did not provide valid information. The existing patented technology is constantly improving the design of this problem, such as designing a hot die-casting process with a thickness of 0.1-1.0mm to make a porcelain veneer made of lithium disilicate-enhanced glass ceramic material (IPS e.maxPress) for clinical color...
