A full dentition plastic splint type transparent tooth fixer

Abstract

The invention discloses a full denture plastic splint type transparent tooth holder. The full denture plastic splint type transparent tooth holder comprises two parts, i.e., an inner rack body and an outer rack body, wherein the inner rack is fixedly connected with the outer rack body through stainless steel wires; the inner rack body and the outer rack body are held close to the buccal and lingual surfaces of teeth and the lingual dental socket mucous membrane; a cavity between the inner rack body and the outer rack body is made according to the size of the teeth; the tooth occlusal surface is fully exposed. The full denture plastic splint type transparent tooth holder is held close to the teeth; the holder is tailored; the inner rack body and the outer rack body are closely attached to each tooth on both buccal and lingual sides without gap in order to provide guarantee for achieving the treatment purpose; the holder is stable to wear, tight, non-leveraging, and comfortable and attractive for a patient to wear, and the temporal-mandibular joint can be effectively protected; the holder is small in size and does not affect the pronunciation or the normal oral function; the inner rack body and the outer rack body of a functional part of the holder are made of plastic and have certain hardness and slight elasticity, the occlusal surface contains no plastic, no wear is caused by the occlusion, and four steel wires for connecting the inner rack body and the outer rack body have certain elasticity, so the holder is firm and difficult to damage.

Description

technical field [0001] The invention relates to a tooth corrector, in particular to a full-dentition plastic splint type transparent tooth fixer. Background technique [0002] At the end of orthodontics, the teeth and periodontal conditions are not yet stable, and it is necessary to wear a retainer for a certain period of time. At present, the common dental retainers are Harley retainers and film retainers. Harley retainers are made of steel wire and plastic. The base structure, because the steel wire is exposed, the base area is large, resulting in a large foreign body sensation in the oral cavity, it is difficult to maintain oral hygiene, easy to scratch and cause oral ulcers and unsightly, and because there are no fixed parts on the outside of the base, it is harmful to the teeth. The fixation effect is also not good; the film-type fixer has a good aesthetic effect, but the plastic diaphragm is not wear-resistant, and the diaphragm is thin and easy to damage, and after we...

Problems solved by technology

[0002] At the end of orthodontics, the teeth and periodontal conditions are not yet stable, and it is necessary to wear a retainer for a certain period of time. At present, the common dental retainers are Harley retainers and film retainers. Harley retainers are made of steel wire and plastic. The base structure, because the steel wire is exposed, the base area is large, resulting in a large foreign body sensation in the oral cavity, it is difficult to maintain oral hygiene, easy to scratch and cause oral ulcers and unsightly, and because there are no fixed parts on the outside of the base, it is harmful to the teeth. The fixation effect is also not good; the film-type fixer has a good aesthetic effect, but the plastic diaphragm is not wear-resistant, and the diaphragm is thin and easy to damage, and after wearing it, because the upper and lower teeth cannot bite together, it will cause temporomandibular joint pain in some patients. Nervous, joint disease occurs, the production process of the film-type fixator is punched out on the plaster model, and there is a gap between the tooth and the tooth, so the fixation effect on the tooth is poor, and it cannot meet the clinical requirements
