Embodiment 1

[0059] A removable denture manufacturing process and method, characterized in that: the method includes the following steps:

[0060] (1) Model trimming process:

[0061] First, use a model trimmer to trim the bottom and surroundings of the model. The thickness from the trimmed bottom to the gums is 0.9-1.2 cm. During the trimming process, the abutment teeth and the corresponding opposing teeth must not be damaged, and the occlusal relationship and the required dissociation can be determined. important part of the end;

[0062] (2) Upper jaw frame:

[0063] Carry out processing according to the specific requirements on the design sheet, and accurately bite the jaw position according to the doctor's biting wax, and then rest the upper jaw, pay attention to the alignment of the midline when the upper jaw is rested, the model should be soaked first, and then the lower jaw and then the upper jaw;

[0064] (3) Row of plastic teeth:

[0065] Fill the undercut. The depth of the ti...

Embodiment 2

[0082] According to the production and method of the removable denture described in Example 1, according to step 5, three wax castings are inserted for the complete denture, and two are placed at the back of the wax base near the back of the teeth, which are auxiliary castings. The one inserted in the anterior tooth area is the main casting channel;

[0083] Partial dentures: three to nine, according to the location of the missing teeth to insert the sprue;

[0084] Single missing tooth: Two wax injection channels, one on each buccal and lingual surface.

Embodiment 3

[0086] According to the manufacture and method of the removable denture described in embodiment 1 or 2, filling the plastic according to step 7 is to convert the wax base into a plastic base, and after the materials are blended, the base water gradually penetrates into the base powder, and The infiltration process is divided into the following six stages:

[0087] (1) Wet sand stage: the tray water has not yet penetrated into the tray powder, and exists between the tray powder particles. It looks like there is less water and more powder. At this time, the reconciliation resistance is small, non-sticky, and it feels like wet sand to the touch;

[0088] (2) Paste stage: the surface of the tray powder is gradually swollen by the tray water, the particles are squeezed tightly, the intergranular gaps disappear, the surface of the mixture appears to have more tray water, and there is no resistance during blending;

[0089] (3) Silk sticking period: the tray water continues to swell ...

Abstract

The invention relates to a manufacturing method of removable dentures. Currently, the removable-denture manufacturing methods in all countries in the world are a thermos-coagulation packing method, need steps such as casing, filling, squeezer pressurizing and water bath polymerization (dental cast cooking pot), are complex in process, time-consuming and labor consuming, are non-uniform in moldingcase pressurizing and are difficult in precise mastering and control of heating speed and heating maintaining time during heat processing. The method has the advantages that the manufacturing flow oftraditional removable dentures is improved, joint height increasing and contraction bubbles of the removable dentures manufactured by the traditional manufacturing process are avoided, and the base-material filling of the partial removable dentures and attachment dentures can be performed; the models of the attachment dentures does not need to be pressurized on a squeezer, and the subfissure or deformation of the fixing-part porcelain teeth of the attachment dentures is avoided.

Description

technical field [0001] The invention relates to a removable denture manufacturing process and a method thereof. Background technique [0002] Removable dentures include partial dentures, complete dentures, and attachment dentures because they have the function of fixed dentures. Therefore, removable dentures are an important part of oral restoration, because the advantages of removable dentures are very few teeth, which are easy for patients to accept, and the key is hygiene and convenience. Unlike fixed dentures, a lot of tooth tissue area needs to be ground. [0003] At present, the production process of removable dentures in all countries in the world is thermal coagulation filling method, which requires multiple steps such as boxing, filling, pressurization, water bath polymerization (boiling dental mold pot), etc. The process is cumbersome and time-consuming Laborious, uneven pressurization of the mold box, and difficult to accurately grasp and control the heating rate...
