Embodiment 1

[0046] Embodiment one: refer to figure 1 , is a removable denture disclosed by the present invention, which includes a base 1 made corresponding to the alveolar ridge of the human body and a bionic tooth 2 connected to one side of the base 1. During the production process, the base 1 corresponds to the alveolar ridge of the human body in the bionic A fitting groove 3 is formed on the opposite side of the tooth 2, and the fitting groove 3 can fit the alveolar ridge of the human body after the movable denture is worn into the mouth.

[0047] Since the base 1 is made of resin material, it still has greater hardness compared with the alveolar ridge of the human body, so some patients will have obvious pain when chewing after wearing it. Therefore, the fitting groove 3 of the base 1 is provided with a There is an elastic cushioning layer 4 for cushioning. The elastic buffer layer 4 is made of silicon rubber material, and nano-silver powder with antibacterial and antibacterial prop...

Embodiment 2

[0051] Embodiment two: refer to image 3 and Figure 4 , is the preparation method of a kind of removable denture disclosed by the present invention, comprises the following steps:

[0052] a: Take an impression of base 1, use medical tools to take out the impression in the patient's mouth, and make two identical gypsum base 1 models A and B that are similar to the patient's mouth according to the impression;

[0053] b: Make a buffer layer, and make an elastic buffer layer 4 with the help of the gypsum base 1 model B;

[0054] b1: Open the connection hole groove 5, and set the connection hole groove 5 with the same position and size at the bottom of the fitting groove 3 formed on the obtained gypsum base 1 models A and B;

[0055] b2: wax-up, wax-up of the obtained gypsum base 1 model B;

[0056] b3: box embedding, put the plaster base 1 model B after wax-up into the embedding box and pour it with gypsum;

[0057] b4: Wax removal and filling. Put the embedding box of b3 int...

Abstract

The invention discloses a removable denture. The removable denture is used for solving the problem of the prior art that a pain feel is triggered by the hard material of the removable denture during achewing process for the reason that the removable denture is directly resisted against an alveolar crest of oral cavity of a patient during a wearing process. The technical point of the invention isthat the removable denture comprises a bionic tooth and a base plate; the bionic tooth is fixed on the base plate; a fitting slot is formed on one side of the base plate away from the bionic tooth corresponding to the alveolar crest of human body; a plurality of connecting holes are formed in the fitting slot at intervals; an elastic buffering layer which is in direct contact with the alveolar crest of human body is arranged in the fitting slot; connecting bulges are arranged on the bottom of the elastic buffering layer; the connecting bulges are blocked in the connecting holes when the elastic buffering layer is jointed in the fitting slot. According to the scheme, the alveolar crest of the patient is in contact with the soft elastic buffering layer during a use process and is prevented from direct contact with the hard base plate, so that the patient can more comfortably and naturally wear the removable denture and the pain feel of the patient while chewing with the removable denturecan be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of oral restoration, in particular to a movable denture and a preparation process thereof. Background technique [0002] As our country enters an aging society, with a large population and the improvement of living standards, people pay more and more attention to oral health. [0003] Removable dentures are widely used at present. Removable dentures have many advantages such as: patients can take off and wear them by themselves, easy to clean, easy to keep dentures clean and oral hygiene, simple manufacturing method, low cost, in line with general consumption level, popular consumption , less tooth tissue is removed than fixed dentures. However, the resin material commonly used to make removable denture bases still has greater hardness compared to the alveolar ridge of the human body, which will cause some patients with serious alveolar bone absorption or many bony protrusions to produce gums after chewing ...
