Novel membrane-pressing type space maintainer

Abstract

The invention discloses a novel membrane-pressing type space maintainer which comprises jaw pads, wherein premature-loss teeth resin teeth are arranged between the jaw pads; a membrane base support is arranged on the jaw pads in such a situation that spaces of the resin teeth and premature-loss teeth are close to base teeth, and the positions, relatively adjacent to the buccal labial surfaces of the base teeth, of the membrane are respectively provided with retaining resin bumps; and grooves which are embossed on corresponding rectangular, elliptic and circular resin parts on the base teeth buccal labial surfaces on the membrane and are in corresponding shapes are united with the retaining resin bumps. The space maintainer disclosed by the invention solves a series of problems of being poor in retaining effect, easy to become loose and fallen, strong in foreign body sensation, failing to recover a certain chewing efficiency, difficult in cleaning, easy to cause carious lesion and the like in a space maintainer for children suffering premature shedding of deciduous teeth.

Description

technical field [0001] The invention belongs to the technical field of medical devices in orthodontics or children's oral cavity, and in particular relates to a novel pressure-membrane gap maintaining device. Background technique [0002] "Premature loss of deciduous teeth" refers to the premature loss of deciduous teeth before the replacement time. Causes include dental caries, trauma, etc. After the premature loss of deciduous teeth, the space is partially occupied and narrowed due to the displacement of adjacent teeth. In the narrowed gap, although a part of the jaw can be restored when the permanent teeth erupt, the erupted permanent teeth are often crowded, misplaced, or even impacted. In particular, the premature loss of the second deciduous molars is more harmful, and often causes the mesial tilt of the first permanent molars, resulting in serious malocclusion. Such diseases will seriously affect the appearance and oral function of children, and should be corre...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the above problems existing in the prior art, and provide a new type of film-type gap maintaining device to solve the problem of poor retention of the gap maintaining device for children with premature teeth loss, easy loosening and falling off, strong foreign body sensation, and inability to restore certain problems. A series of problems such as chewing efficiency, difficult to clean and easy to cause caries
