The utility model provides a kind of complete denture 1 and artificial tooth component, and provides embodiments thereof.
As Figure 1-Figure 4, complete denture 1 provided by the utility model comprising have upper dental assembly 10 and lower dental assembly
20, upper dental assembly 10 and lower dental assembly 20 include basal seat area 100 and artificial tooth corona 200, and artificial tooth corona 200 is set to justice
On the top of tooth base 100, the bottom of basal seat area 100 is set as concavo-convex, and convex portion gos deep into alveolar ridge；Artificial tooth corona
Multiple through-holes are provided on 200, basal seat area 100 and artificial tooth corona 200 thermoplastic is filled with by the through-hole on artificial tooth corona 200
Property elastic resin material is fixedly connected in a manner of welding；Setting in the artificial tooth corona 200 of upper dental assembly 10 and lower dental assembly 20
There is same sex magnetic patch 210, so that upper dental assembly 10 and lower dental assembly 20 are mutually exclusive by magneticaction.It is provided by the utility model
Complete denture 1 is by setting concavo-convex for the bottom of basal seat area 100, so that the convex portion of the bottom of basal seat area 100
Go deep into alveolar ridge increasing the fixing intensity between basal seat area 100 and gum, the justice of upper dental assembly 10 and lower dental assembly 20
Teeth are preced with 200 occlusal contact conditions and constitute occlusal surface, and the inside active force of lip buccinator muscle and the outside active force of lingualis are in equilibrium state,
The load that artificial tooth corona 200 is born when in use is transferred to supporting tissue by the bottom of basal seat area 100；And by upper
Same sex magnetic patch 210 is set in the artificial tooth corona 200 of dental assembly 10 and lower dental assembly 20, passes through what is formed between same sex magnetic patch 210
Magnetic mutual expelling force, the basal seat area 100 of dental assembly 10 and lower dental assembly 20 in related influence, so that basal seat area 100 is close to
Lower gum increases the adhesive force between basal seat area 100 and gum, so that upper dental assembly 10 and lower dental assembly 20 are being stung
Complete denture 1 can be still firmly fixed on gum when conjunction acts or dehisces silent, will not fall off；And use thermoplastic
Property elastic resin material is molten into liquid, 100 model forming of mould filling basal seat area at high temperature, and is injected into artificial tooth corona
In 200 aperture, when solidification to be cooled, basal seat area 100 strikes up partnership with artificial tooth corona 200, secure rigid, basal seat area
Between 100 and artificial tooth corona 200 by the way of this welding physical connection, do not need to influence beautiful metal clasp, will not
Lead to the problem of metal allergy.
Spill is made in the junction of basal seat area 100 and root of the tooth.The purpose being arranged in this way is, passes through the work of lip cheek lingualis
With basal seat area 100 is attached on root of the tooth ridge, enhancing the maintenance of complete denture 1, is conducive to maintenance and stabilization, light is answered in this face,
It is beautiful and comfortable.Specifically, the thickness of the junction of basal seat area 100 and root of the tooth can be between 1.5-2.5 millimeters, blocked up meeting
Influence 1 maintenance of complete denture and face and soft tissue movement, excessively thin then frangibility.
There is machining allowance at the base edge of basal seat area 100 along its direction of extension.The processing of existing complete denture 1 is usual
By artificial tooth, skilled worker is completed, this alleviates the work of doctor really, but also to doctor and patient there are drawback, present skilled worker is several
Be not on it is excessively clinical, the oral cavity of patient and face type are changeable, and the communication of doctor and skilled worker are easy to appear deviation, in this way
The complete denture 1 worked it out might have the case where not being adapted to patient, need to do over again, and the period is longer, therefore this is practical
The complete denture 1 of novel offer is provided with certain machining allowance along its direction of extension at the base edge of basal seat area 100, doctor
Life clinical can be adjusted complete denture 1 according to the case where patient.Preferably.Machining allowance can be 2 millimeters.
Basal seat area 100 and artificial tooth corona 200 are all made of thermoplastic elastomer resin material and are made.Thermoplastic resin have by
No matter thermal softening, the performance of hardening by cooling, and not chemically reactive, heat and cool down and repeat how many times, is able to maintain
This performance.
Further, it is interconnected between through-hole.Such setting can make artificial tooth corona 200 and basal seat area 100
It is more firm to be tightly secured together.
Complete denture 1 further includes having connector, and fixed bit is provided on upper dental assembly 10 and lower dental assembly, and connector is used
It links together in by upper dental assembly 10 and lower dental assembly.1 component of complete denture includes upper dental assembly 10 and lower dental assembly, the two
The phenomenon that being separately provided when being removed from the gum of patient, be likely to result in loss, therefore connector is set, in upper 10 He of dental assembly
The two is fixed together by lower dental assembly after removing from the gum of patient, using connector, to prevent one of both from losing
It loses.
Specifically, fixed bit is the assembling axis for being removably attached to basal seat area frontside edge；Connector includes first
One end of elastic slice and the second elastic slice, the first elastic slice and the second elastic slice is mutually permanently connected, and the other end of the first elastic slice passes through assembling
Axis is fixed on the basal seat area frontside edge of dental assembly 10, and the other end of the second elastic slice is fixed on lower dental assembly by assembling axis
Basal seat area frontside edge.
Artificial tooth component provided by the utility model comprising there are complete denture 1 and denture cleaning component as described above,
Denture cleaning component is for cleaning complete denture 1.The complete denture 1 provided in artificial tooth component provided by the utility model with it is existing
Complete denture 1 compare, the convex portion of the bottom of basal seat area 100 gos deep into alveolar ridge increasing basal seat area 100 and tooth
Fixing intensity between gum, and same sex magnetic patch 210 is set in the artificial tooth corona 200 of upper dental assembly 10 and lower dental assembly 20, lead to
The magnetic mutual expelling force formed between same sex magnetic patch 210 is crossed, so that basal seat area 100 is close to upper lower gum, increases basal seat area
Adhesive force between 100 and gum, so that upper dental assembly 10 and lower dental assembly 20 are when carrying out snap-action or dehiscing silent
Complete denture 1 can be still firmly fixed on gum, will not fall off；And using thermoplastic elastomer resin material in high temperature
When be molten into liquid, 100 model forming of mould filling basal seat area, and be injected into the aperture of artificial tooth corona 200, it is to be cooled solidifying
Gu when, basal seat area 100 strikes up partnership with artificial tooth corona 200, secure rigid, adopts between basal seat area 100 and artificial tooth corona 200
With the mode physical connection of this welding, does not need to influence beautiful metal clasp, metal allergy will not be led to the problem of.
In conclusion complete denture 1 provided by the utility model comprising there are upper dental assembly 10 and lower dental assembly 20, on
Dental assembly 10 and lower dental assembly 20 include basal seat area 100 and artificial tooth corona 200, and artificial tooth corona 200 is set to artificial tooth base
