Embodiment Construction

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

[0026] The manufacturing method of the veneer restoration color chart system of the present embodiment includes the following steps:

[0027] S1. Veneer preparation is performed on the standard tooth model to form a standard-shaped abutment.

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

Abstract

The invention relates to the technical field of oral restoration equipment, and specifically discloses a veneer restoration colorimetric system and a manufacturing method thereof. The female mold is filled with different tooth color resins respectively to make resin abutments of different shades, and they are arranged in the order of specified shades, and the digital images before and after the preparation of the standard tooth model are obtained by using a scanner. , Using the replication method, CAD / CAM computer-aided design of the veneer whose surface morphology is consistent with the prepared part of the standard tooth model, selects different materials for veneer production, and arranges them according to different material classifications. The invention can be consistent with clinical practice, fully consider the influence of porcelain material, adhesive tone, and abutment color on the final aesthetic effect of the restoration, and select the color of the resin abutment and veneer combination to predict the color of the veneer restoration with the best effect. , restore the natural aesthetic effect of the affected tooth.

Description

technical field [0001] The invention relates to the technical field of oral restoration equipment, in particular to a veneer restoration color guide system and a manufacturing method thereof. Background technique [0002] The matching of the color of the veneer restoration to the natural teeth is one of the main criteria for the success of the restoration. At present, in the clinical veneer restoration colorimetry, the restoration color guide (mainly Vita 3D Master color guide) is used to compare the color of the natural teeth, select the target color of the veneer restoration, and how to choose the porcelain material for the physician or technician , abutment color does not provide valid information. The existing patented technology is continuously designed to improve this problem, such as designing a 0.1-1.0mm thick hot die casting process to make a porcelain veneer of lithium disilicate reinforced glass-ceramic material (IPS e.maxPress) for clinical colorimetry, or Desi...
