Description

Dental mixed porcelain veneer and manufacturing method thereof
Technical Field
The invention relates to the technical field of dental medical instruments, in particular to a dental mixed porcelain veneer and a manufacturing method thereof.
Background
The porcelain facing is a fixed prosthesis, is used for the surface defect of the tooth body of a patient, coloring, discoloring, enamel dysplasia, tetracycline pigmentation tooth, dental fluorosis, deformed tooth, overlarge tooth space, adjacent surface caries, incisal end defect and the like, and adopts a repair mode of relatively few molar teeth to bond porcelain repair materials on the surface of the tooth body to recover the normal shape of the tooth body and improve the color and luster of the tooth body.
In the prior art, the labial side of the tooth body is generally covered by a porcelain facing completely, the lingual side of the tooth body is covered by a porcelain facing partially, and the labial side and the lingual side of the porcelain facing are made of the same material. The porcelain facing is divided into two types according to the manufacturing method. The other is cast porcelain facing, namely the manufacturing of the porcelain facing is completed by a die-casting mode: firstly, a veneering wax pattern is manufactured on a prepared abutment substitute pattern or is designed by a digital software, the veneering wax pattern is printed by 3D, then the wax pattern is embedded, a porcelain veneer is obtained by die casting, and the manufacturing of the porcelain veneer can be completed by porcelain coating or selecting a glazing mode in the later stage. The porcelain veneer of the type has better strength and toughness and natural color, but the required thickness is not less than 0.6mm, and more tooth tissues need to be ground. The other method is to finish the production of the porcelain veneers by CAD/CAM processing, firstly, the data in the mouth or the data of a scanner is obtained, the appearance of the tooth body is restored by the design of software, then, a prototype is formed by high-precision cutting, and finally, the production is finished by artificial glazing or polishing. The method has higher precision, but the simulation degree of the color is slightly different from that of the natural tooth in the mouth due to the limitation of the color of the cut porcelain block. The porcelain veneering repair material mainly comprises the following three materials: glass ceramics, zirconia ceramics and feldspar ceramics, wherein the feldspar ceramics are porcelain facing materials with the best aesthetic effect, but the use of the feldspar ceramics is influenced because the mechanical strength is poor and the risk of cracking the porcelain is high when the feldspar ceramics perform functions in the mouth.
Chinese patent document with publication number CN 110269701A and publication date of 2019, 09 and 24 discloses a method for manufacturing a fully-wrapped ultrathin porcelain veneer, which comprises the following specific steps: (1) preparing a tooth model of the tooth body subjected to minimally invasive preparation; (2) preparing a fully-wrapped ultrathin veneered wax model according to the tooth model; (3) according to the wax pattern in the step (2), a casting channel is arranged on the wax pattern, and the porcelain block is subjected to embedding casting treatment to obtain a restoration body; (4) removing and embedding the prosthesis, and removing the reaction layer; (5) polishing the restoration, and finally glazing and sintering to finish the preparation of the porcelain veneer.
Although the prepared porcelain veneer has strong pressure resistance, is attached to teeth and is not easy to collapse, the method for manufacturing the fully-wrapped ultrathin porcelain veneer disclosed by the patent document needs to abrade more tooth tissues, and the labial repair color is not good enough, so that the aesthetic effect is influenced.
