Description

Combined denture with hemispherical magnets and preparation method thereof

Technical Field

The invention relates to the technical field of false teeth, in particular to a combined false tooth with a hemispherical magnet and a preparation method thereof.

Background

The artificial tooth is an artificial tooth for replacing a missing natural tooth, also called as a false tooth, and is a general term for a prosthesis manufactured after a part of or all of upper and lower teeth are missing in medicine. Partial or even complete loss of dentition can be caused due to severe periodontal disease, dental caries, trauma and the like, facial appearance, pronunciation and chewing functions can be affected after the loss of teeth, gastrointestinal burden is increased, and adjacent teeth can be obliquely displaced if the teeth are not repaired in time, so that jaw teeth are stretched and the occlusion is disordered. The artificial tooth is divided into removable type and fixed type. Fixed dentures cannot be taken by the patient himself, whereas removable dentures can be taken by the patient easily.

Removable dentures are known as "removable partial dentures". It is a prosthesis which is supported by natural teeth left in the oral cavity and mucous membrane and alveolar bone covered by a base and can be taken by a patient. The movable false tooth is fixed and stabilized by means of the false tooth fixing body and base support, and is used in repairing missing tooth and adjacent soft and hard tissue.

The materials for making movable artificial teeth can be divided into plastic teeth, porcelain teeth and metal teeth. In order to prevent the artificial teeth from being longitudinally folded, for the people with too small gap between teeth or too small distance between gums, cast metal teeth or metal teeth, a support and a clamping ring can be integrally cast, so that the purposes of attractive appearance and durability are achieved. At present, in the process of using the denture for a long time by a patient, the denture can be seriously worn and even fall off, but because the whole denture is fixedly connected with the base and cannot be disassembled and replaced, the denture needs to be replaced again, the economic burden of the patient is increased, and waste to a certain extent is caused.
