Abstract

The invention provides a large-area mucous membrane support-type false tooth and a production method thereof, which relate to the technical field of artificial false tooth. The large-area mucous membrane support-type false tooth comprises an abutment tissue part, an abutment polishing part, and an artificial tooth; the abutment tissue part and the abutment polishing part are connected, the abutment tissue part is used for abutting against a palate mucous membrane in oral cavity, an upper alveolar ridge mucosa and a lower alveolar ridge mucosa, the abutment polishing part is used for abuttingagainst a lip-cheek mucous membrane of the oral cavity and soft tissue of tongue, the abutment tissue part is connected with the artificial tooth, and a Shore hardness value scope of the abutment tissue part is A20-A80. The elastic buffer of the abutment tissue part is used for compressing the mucous membrane and the bone, ache generation is reduced, and the patient satisfaction is increased; a tight sealing degree of the false tooth tissue is increased, the false tooth edge is enclosed, overlarge or nonuniform occlusal force is buffered and absorbed, the material is stretched in a tissue undercut area, so that retention capability of a restoration body is increased, and the muscle and joint of the patient are coordinated, so that the mastication efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of artificial dentures, in particular to a large-area mucosa-supported denture and a manufacturing method thereof. Background technique [0002] Tooth loss at the free end or total tooth loss is a more serious situation in tooth loss. Because more missing teeth have a greater impact on the patient's function, they all require large-area mucosa-supported dentures to restore; large-area mucosa-supported dentures are related to oral cavity The part in contact with the mucosa is the tissue surface material of the denture base. Traditionally, hard and rigid resin materials are used, such as thermosetting resins, self-curing resins, light-curing resins, thermoplastic injection molding resins, etc.; Poor tissue adaptability; studies have shown that about 5%-20% of large-area mucosa-supported dentures, such as complete dentures, removable dentures with missing teeth at the free end, and implant overdentures, have po...
