Abstract

The invention relates to a manufacturing method of cast porcelain dental veneer, comprising the following steps: constructing a diagnostic model by digital three-dimensional technology, and making the diagnostic model by means of three-dimensional printing; making a diagnostic model for a patient based on the diagnostic model using a temporary crown material Veneering; on the basis of the diagnostic veneer, perform tooth preparation, impression taking, and superhard plaster filling of the patient to obtain a working model, and perform three-dimensional scanning and centric occlusal registration on the working model; the work after tooth preparation The spatial registration of the model and the diagnostic model is carried out so that the two models are completely consistent in the posterior region, and the edge line of each preparation is constructed in the difference area of ​​the anterior labial surface by using the NURBs curve; The veneer is directly used for lost-wax casting to obtain a veneer made of cast porcelain material. The cast porcelain tooth veneer made by the invention achieves the unity of appearance and function after restoration.

Description

technical field [0001] The invention relates to the technical field of dental veneer design, in particular to a manufacturing method of cast porcelain dental veneer. Background technique [0002] With the development of the economy and the improvement of people's living standards, people have higher and higher requirements for oral aesthetics. However, in reality, the appearance is often affected by tapered teeth, scattered gaps between teeth, and abnormal tooth color. The traditional treatment method mostly uses full crown restoration, but it will wear away a large amount of tooth tissue, resulting in frequent tooth and periodontal problems. How to preserve the dental tissue as much as possible under the premise of ensuring the appearance, health and function is the goal of the prosthodontist. Porcelain veneers have become a hot spot in minimally invasive restorations in recent years due to less tooth tissue removal. At present, traditional lost-wax casting porcelain vene...
