Preparation of stand type hollow artificial tooth

Abstract

The invention relates to a preparation method of a frame type hollow denture, which has the steps as follows: (1) the maxillary defects are copied, thus preparing a maxillary module, a frame and a denture tissue surface base plate; (2) the hollow part of the denture tissue surface base plate is filled with wax, thus aligning artificial teeth and using the wax for producing a denture grinding surface base plate wax model; (3) silicon rubber are used for complex model of the artificial teeth and the denture grinding surface base plate wax model, thus obtaining a silicon rubber mold; (4) the silicon rubber mold is taken off, the denture grinding surface base plate wax model is scraped by 1.0 to 1.5mm, the silicon rubber mold is worn back, self-curing resin material is used for filling, thus obtaining a denture primary part; and (5) a hole is opened on the denture grinding surface base plate of the denture primary part, the heating is carried out, and the opened hole is sealed again aftermelting and discharging the filled wax for preparation. The frame type hollow denture tissue surface prepared by the method is well contacted with mucous membrane of a patient, thus improving the denture comfort of the patient, reducing the times of the revisits, reducing the clinical medical costs, lowering the processing difficulty of the denture and facilitating the manufacture.

Description

technical field [0001] The invention relates to a method for preparing dentures, in particular to a method for preparing bracket-type hollow dentures. Background technique [0002] The maxillary defect caused by tumor surgery or trauma often has a large defect range, and it is necessary to use prosthetics to improve the patient's facial shape and restore oral physiological functions at the same time. When performing restoration, in addition to repairing the defective dentition, it is also necessary to fill the hollow part formed by the defect of the maxilla, that is, it needs to be repaired with a prosthesis. Because the defect is large, the prosthesis is large and heavy, and the retention is poor. In addition to using the remaining teeth and tissue undercuts in the mouth as much as possible for retention, the weight of the restoration should also be reduced. At this time, the restoration is usually made into a hollow bracket-type hollow denture. [0003] Existing frame-typ...

Problems solved by technology

Since the base of the polished surface of the denture is distributed with metal brackets, the gypsum or quartz sand cannot be discharged smoothly due to the obstruction of the metal brackets. Therefore, holes can only be made on the tissue surface of the denture.

However, the tissue surface of the denture is directly in contact with the patient's mucous membrane, and any slight change will cause great discomfort to the patient. Therefore, the repair of the opening is extremely demanding, which increases the difficulty of the denture processing technician's operation; at the same time, it also increases the patient's follow-up visits and adjustments. times, increasing the pressure on physicians and increasing medical costs
