Description

Telescope crown

Technical field

The utility model relates to mouth medical technology fields, more specifically, it is related to a kind of telescope crown.

Background technique

Telescope denture is a kind of fixation, activity joint dummy.Telescope crown, which refers to, has high adaptation by making Double-layer crown, by internal layer hat cement on abutment, outer layer hat be placed in removable denture, by between inside and outside hat it is closely sealed generate rub Wiping power makes denture retention.The telescope denture scope of application is very wide, and the restorative procedure all can be used in various types of defect of dentition, especially It is applicable in most tooth missing, and a small number of teeth retain the reparation of (single jaw only remains 1~5 natural teeth).

But fixed between interior hat and outer hat by frictional force, make between interior hat and outer hat to wear, it is of long duration , so that the size between interior hat and outer hat is changed, interior hat and outer hat caused not to be adapted to, to make interior hat and the connection of outer hat not Stablize.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of telescope crown, by being preced with outside A kind of clamping structure is provided between interior hat, instead of it is outer hat interior hat between frictionally securing, reduce it is outer hat with inner tube it Between abrasion, make it is outer hat with interior hat connection it is stronger.

To achieve the above object, the utility model provides following technical solution:

A kind of telescope crown, including on plaster cast, setting and plaster cast interior hat, tooth seat and be opened in tooth seat bottom Outer hat, be installed with artificial tooth at the top of tooth seat, be installed with pluggable in the bulb in appearance at the top of the interior hat, bulb has Certain elasticity.

The bulb of interior hat is plugged in outer hat when tooth seat and plaster cast are fixed by using above scheme, Outer hat is fixed with interior hat, tooth seat can be made to fix with plaster cast, i.e., artificial tooth is installed in oral cavity, between outer hat and interior hat Clamping reduces the abrasion between outer hat and interior hat, connects outer hat with interior hat stronger.

Preferably, the bottom of the bulb is provided with spring.

By using above scheme, spring can play buffer function to bulb, when bulb is preced with interior grafting outward, spring Bulb can be prevented to be damaged to plaster cast.

Preferably, being provided with connecting rod between the open end two sides of the tooth seat.

By using above scheme, connecting rod can enhance the connection between tooth seat two sides, connect the both ends of tooth seat more steady It is fixed.

Preferably, being bolted between the both ends and tooth seat of the connecting rod.

By using above scheme, bolt is fixed, easy for removal and installation, is facilitated and is removed connecting rod from the funeral of tooth seat, to even Bar is cleaned.

Preferably, matcoveredn is arranged in the top of the connecting rod.

By using above scheme, the tongue that protective layer can be avoided people is directly contacted with connecting rod, enhances the comfortable of tongue Property.

Preferably, being to be detachably connected between the protective layer and connecting rod.

Removable between protective layer and connecting rod by using above scheme, Fang Baini carries out replacement to protective layer or will protection Layer disassembly is cleaned.

Preferably, the both ends including layer offer gap slot, gap slot can be connected in the both ends of connecting rod.

By using above scheme, clamping also facilitates protective layer being plugged in company convenient for removing protective layer from connecting rod On bar.

In conclusion the utility model has the advantages that compared with the prior art

1. the top being preced in is installed with bulb, and the stage of tooth seat is installed with outer hat, and bulb has certain elasticity, can be by ball Head is plugged in outer hat, and outer hat is fixed with interior hat, tooth seat can be made to fix with plaster cast, i.e., artificial tooth is installed on oral cavity It is interior, it is clamped between outer hat and interior hat, reduces the abrasion between outer hat and interior hat, connect outer hat with interior hat stronger；

2. being removably connected with connecting rod between the open end two sides of tooth seat, connecting rod can be reinforced firm between tooth seat both ends Property, matcoveredn is detachably connected on connecting rod, and the tongue that protective layer can be avoided people is directly contacted with connecting rod, enhances relaxing for tongue Adaptive.
