Embodiment Construction

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the best embodiments.

[0031] A kind of preparation method of the artificial tooth that is compounded with soft liner, comprises the steps:

[0032] 1) Confirm the impression; according to the shape and size of the patient's dental arch, take the impression, and then produce the denture corresponding to the impression; the denture includes a hard base and artificial teeth set on the hard base;

[0033] 2) Infusion of gypsum: Inject gypsum into the denture impression obtained in step 1). After the gypsum hardens, modify the shape to obtain a plaster model containing dentures that is compatible with the shape of the patient's alveolar ridge; remove the dentures to obtain a plaster soft lining Model;

[0034] 3) Prepare the gypsum negative mold; put on the joint frame, use pl...

Abstract

The invention belongs to the field of medical instruments and particularly relates to a denture composited with a soft lining and a preparation method of the denture. The production method comprises the steps as follows: 1) impression confirmation; 2) gypsum filling; 3) gypsum impression production; 4) soft lining gasket production; 5) polishing of a tissue surface in the position where a hard base and the alveolar crest of a patient are contacted for guaranteeing the space of the soft lining; 6) wax sealing; 7) embedding; 8) packing of thermosetting resin; 9) addition of a surfactant after polishing, coating of the surface of the surfactant with a soft lining material, pressurization for bubble removal and thermal polymerization; 10) polishing and adjustment. The retention of the denturecomposited with the soft lining is remarkably improved, pressing pain is relieved or eliminated through elastic deformation of the soft lining material, and meanwhile, the soft lining material has high fitting degree with the dental arch of the patient, is high in wear resistance, can be relined after being used for 3-5 years generally and is low in cost and convenient to popularize.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a denture compounded with a soft liner and a preparation method thereof. Background technique [0002] Dentures are dentures that are inlaid to restore functions such as chewing, aesthetics, and pronunciation after tooth loss or extraction. The bases of existing dentures are mostly made of resin materials. The contact between the hard base and the oral cavity will make the wearer feel uncomfortable, and the strength of the resin is not high. The bite force during chewing will cause the base base to deform or crack, thus affecting wearing normal use; [0003] The total denture produced at present all is that the tooth body is set on the hard plastic base made of dental tray powder, and the hard plastic base needs to be stuck on the gum bed when the patient installs the total denture. In this way, it is very troublesome to make the hard plastic base, and the impression ...
