Abstract
The utility model relates to oral treatment technology, discloses a retainer of a connecting rod telescopic crown denture, and solves the problems that the denture in the prior art is unstable in retention and easily causes injury on adjacent good teeth. According to the retainer disclosed by the utility model, an inner crown is fixedly glued to a butment, an outer crown and an active denture are integrally connected, retention force is generated by a mosaic body between the inner crown and the outer crown on a metal connecting rod, and when the telescopic crown denture is applied to restoring a missing tooth, the missing tooth and the butment are connected to generate integral retention force. The retainer of the connecting rod telescopic crown denture is composed of a semi-fixing base supporting plate (1), a semi-fixing active denture (2) and a telescopic crown outer crown plasticized tooth body (3), wherein the inner crown (5) and the outer crown (7) of the connecting rod telescopic crown are cast from one of a nickel chromium alloy, a cobalt chromium alloy, pure titanium, and a gold alloy. The retainer disclosed by the utility model has the advantages of beautiful and comfortable denture, stable retention, and excellent chewing function, and the denture does not cause injury on the adjacent good teeth.
Description
Technical field
This utility model relates to the dental care technology, specifically link rod sleeve hat artificial tooth retainer.
Background technology
Telescope crown denture retention technology has the history of year clinical practice surplus in the of 40 abroad, refer to the telescope crown be single only, the removable denture of two retainers.The pyramid type telescope retainer of introducing on 2005 the 19th volumes of domestic stomatology magazine the 4th periodical forms wedging action between outer hat and the interior hat, and maintenance and the stability of dummy back in place artificial tooth are recovered masticatory function.But its leaf-comb retainer has the shortcoming of inapplicable most tooth missing.The 3rd the 4th phase of publishing on the contemporary Chinese medicinal application journals and periodicals of volume of February in 2009 goes up to inquire into and uses clinical practice and the reparation that sleeve is preced with combined clasp formula casting removable denture outward, on the abutment of both sides, missing tooth gap, adopt outside the different sleeves method of hat or clasp retention to make respectively and can pluck support, its shortcoming is can pluck support to influence adjacent good tooth and cause damage, uses the several years after-poppet to come off.Report the clinical practice of telescope crown artificial tooth in August, 2009, selecting remaining tooth is that abutment plays the maintenance effect, and abutment and base plate undertissue cell are born power jointly, and then the histiocytic atrophy of soft or hard and absorption under the base plate occur, artificial tooth sinks, and causes the shortcoming of periodontal tissue's damage.Therefore it is stable to invent a kind of denture retention, and it is very necessary that adjacent good tooth is not caused the link rod sleeve hat artificial tooth retainer of damage.
The utility model content
It is stable that the purpose of this utility model provides a kind of denture retention, adjacent good tooth do not caused the link rod sleeve hat artificial tooth retainer of damage.
This utility model is achieved in that
A kind of link rod sleeve hat artificial tooth retainer, comprise that hat, telescope crown are preced with in metal connecting rod and the telescope crown outward, interior hat cements on the abutment, outer hat and removable denture are linked to be integral body, produce maintenance power by the chimera between interior hat on the metal connecting rod and the outer hat, also comprise semifixed base plate, semifixed detachable dental prostheses, the telescope crown roasting tooth body of moulding of hat outward.
Hat, telescope crown are preced with outward in the described telescope crown, are formed by a kind of casting in nichrome, cochrome, pure titanium, the billon.
This utility model relates to a kind of link rod sleeve hat artificial tooth retainer, comprise hat in metal connecting rod and the telescope crown, telescope crown is preced with outward, interior hat cements on the abutment, outer hat and removable denture be linked to be integral body, in on the connecting rod metalwork, be preced with and the maintenance of the generation of the chimera between the hat outward power, can bear the bigger masticatory force of artificial tooth, strengthen firmly, abutment is difficult for splitting off, both can increase the service life, also can select usefulness to comparatively loosening abutment again, loosening tooth must can be played clamping plate to loosening tooth and fix in supporting and stable tooth maintenance power, make artificial tooth firm, attractive in appearance, comfortable, masticatory function is good.This utility model is broken through detachable dental prostheses and single telescope crown artificial tooth using value of a lot of buckle in the known technology.Thereby be conducive to single tooth motion, and change the mass motion of abutment into, increase the abutment maintenance and transmitted tooth with joint efforts.The wire point-like that is different from other maintenance is cone face shape with contacting of abutment, is conducive to maintenance and transmits tooth and make a concerted effort, the shortcoming that overcome existing telescope crown leaf-comb, double comb artificial tooth, can pluck support.
The maintenance power of this utility model link rod sleeve hat retainer can be regulated according to the situation of abutment, and the maintenance power of retainer and the poly-dynamics of interior hat have direct relation, and the poly-dynamics of interior hat is the 0-12 degree, and it is more satisfactory generally to be chosen to be 6 degree.Obviously become flexible under the telescope crown condition as abutment, the cohesion angle of scalable is to reduce the burden of abutment.
Another characteristics of this utility model are that the artificial tooth volume is little, and foreign body sensation obviously reduces, and dirt easy to clean around the abutment is more convenient, just thorough simultaneously, is conducive to abutment periodontal cell health.
Link rod sleeve hat artificial tooth retainer of the present utility model; not only has the chimeric clamping plate effect between the inside and outside hat; and have more the maintenance effect of the dual metal splint of disjunctor between the hat in the telescope crown; after artificial tooth is in place; abutment and abutment are linked to be an integral body; make the motion of repairing preceding single tooth be transformed into the mass motion of abutment; increase abutment like this and born the bigger distribution of making a concerted effort of artificial tooth; and delay the absorption of free-end region alveolar ridge; when acting on artificial tooth, the external force of artificial tooth all directions disperseed rapidly; played protecting group sound of baby talk week histiocyte health, the effect that increases the service life, performance excellent function.
After abutment improves root canal, under the no condition of poor, then to the abutment tooth preparation, join and do with porcelain tooth abutment less than 1 millimeter, when preparation, also should consider common path of insertion, then, delivery, irritate mould, make plaster model, make hat in disjunctor Metallic rod and the telescope crown, be preced with through clinical trying in the telescope crown, debug suitable after, remake secondary silicone rubber delivery, make the outer hat of telescope crown and metal rack detachable dental prostheses, try and use the hat in the link rod sleeve hat that is adhesively fixed on through clinical again, wear again that telescope crown is preced with and metal rack detachable dental prostheses artificial tooth is in place outward.
The utility model has the advantages that:
1. artificial tooth is attractive in appearance, comfortable, maintenance stable, and masticatory function is good.
2. artificial tooth does not cause damage to adjacent good tooth.
