Manufacturing method of comfortable full-mouth adsorption false tooth meeting aesthetic function

Abstract

The invention relates to a manufacturing method of a comfortable full-mouth adsorption false tooth meeting an aesthetic function, and belongs to the field of false tooth manufacturing, wherein the method comprises the steps: drawing a central line, a mouth angle line and a lip base line on a temporary base plate loaded with a wax rim after occlusion mouth testing, and taking a bisector of jaw spacing after mouth testing; marking out an incision edge connecting line of the anterior incisor below the lip base line, and marking out a smile line above the lip base line; connecting the incisor edge line of the anterior incisor with the bisector of the jaw spacing after mouth testing to form a tooth arrangement plane curve on the same plane, wherein the mouth angle line is a positioning line between a three-tooth distal center and a four-tooth proximal center, the curve length from the mouth angle line to the central line is the basis for determining the width specification of the whole set of false tooth, the smile line is a base line for determining the tooth neck of the anterior incisor, and the distance from the smile line to the incisor edge connecting line of the anterior incisor is the basis for determining the height specification of the whole set of false tooth. Therefore, specification parameters of the whole set of false teeth and tooth arrangement positions of the false teeth can be determined, and the method is simple and easy to implement and has aesthetic characteristics on the premise of meeting false tooth functions.

Description

technical field [0001] The invention belongs to the technical field of denture production, and in particular relates to a production method of a comfortable full-mouth adsorption denture satisfying aesthetic functions. Background technique [0002] Dentition loss is a common oral disease in modern medical care, and it mostly occurs in the elderly. Among them, edentulous patients account for a relatively high proportion. As my country enters an aging society, the number of edentulous patients will continue to increase. At present, among the oral restoration methods for edentulous patients, complete denture restoration is the most common and main method. [0003] In the process of making complete dentures, obtaining an artificial dentition that fits the patient's oral characteristics is one of the key steps to the success of the restoration. A good artificial dentition can effectively restore the patient's masticatory function, reshape the facial shape, and enhance the patient...

Problems solved by technology

[0004] The production of traditional porcelain dentures is still the main method of complete dentures. The dentures in this method often use standard sets of teeth, and the standard sets of teeth are also in the form of series; The selection of the best type is often based on the experience accumulated by the dentist for a long time and his own understanding of the impression of the patient's mouth. Although some other technical requirements will be followed in this process, in the final analysis, most of them rely on experience, so , it has formed the current situation of low manufacturing precision, high treatment cost, long production cycle and high requirements for technicians for the treatment effect.

[0005] Various technologies for research on the deficiencies of traditional technologies have also emerged. Among them, Chinese patents CN105380723B and CN108814743A disclose technical solutions for 3D printing dentures based on computer three-dimensional scanning and CAD. In these two technologies In the scheme, the extracted oral information of the patient includes the three-dimensional model of the oral cavity, the dental floss of the front teeth of the upper and lower jaws, the left mouth corner line, the right mouth corner line, the lip high line, the lip low line and the median sagittal plane, etc.; In the two technical solutions, it can be clearly seen that the purpose of using the left mouth corner line and the right mouth corner line is to build a fullness curve, but the role of the lip high line and lip low line is not mentioned. At the same time, due to the Due to the limitations of denture materials, there are currently no materials that can meet the needs of stomatology, which also makes the path of more advanced 3D printing complete dentures appear certain uncertainty
