Description
Technical field
The present invention relates to a kind of Dental Implant, be specially a kind of suspention corona formula Dental Implant.
Background technology
The Dental Implant technology faces two problems, i.e. maintenance form problem and drag form problem.Maintenance form problem relates to the relation of being connected and fixed between each parts of Dental Implant, and drag form problem relates to the transitive relation of the power between each parts of Dental Implant.
Existing Dental Implant, its structure generally comprises: in the root of the tooth of root pipe is arranged, thrust the tooth stake of root of the tooth root pipe and be placed in corona in the tooth stake by dowel pin.On the maintenance form, because the corona of existing Dental Implant is (being case shape formula fixed structure) that is fixed in the tooth stake, for guaranteeing that corona reliably is fixed in the tooth stake, prevents that corona from coming off in the process of chewing, the size up and down of corona is bigger, cause plantation corona stake interface and gingiva to intersect, make a hat stake interface place easily fill in food debris and be difficult to brush teeth self-cleaning, serious meeting causes the gingiva inflammation.On the drag form, existing Dental Implant more stresses the maintenance of Dental Implant itself, and the Cushioning Design of external force is considered deficiency, and corona is chewed pressure suffered in the process and directly is delivered on tooth stake and the root of the tooth; Continual masticatory force has caused Dental Implant to the continual compressing power of alveolar bone, and this compressing power has been induced the generation of alveolar bone osteoclast, and then atrophy has played the influence of dominance to alveolar bone bone wall, causes becoming flexible, coming off of Dental Implant.Though the Dental Implant corona that has now and the contact surface of tooth stake are provided with elastic buffering pad, but because it does not fundamentally change the force way (being the compressing power that remains that corona passes to tooth stake, root of the tooth) of Dental Implant, be provided with elastic buffering pad between corona and the tooth stake and can only partly alleviate the compressing power of transmission, fundamentally do not solve the drag form problem of Dental Implant.
Theory of medicine thinks that the pressure inducement osteoclast generates, and pull strength induced osteogenesis cell generates.
The mechanics principle of nature tooth be alveolar bone with root of the tooth between fibre bundle by dental bed connect, natural tooth is as being suspended in the alveolus, makes fibre bundle one end stretching from the masticatory force of different directions, corresponding end relaxes.Under the normal masticatory force state, root of the tooth has only distraction force and does not oppress power alveolar bone bone wall, and the generation of distraction force energy induced osteogenesis cell.Therefore, natural tooth can not cause the destruction to alveolar bone.
Summary of the invention
The present invention is directed to the problem of existing Dental Implant, a kind of suspention corona formula Dental Implant is provided in maintenance form (hat stake interface is low excessively) and drag form (suffered is compressing power) existence.
The present invention adopts following technical scheme to realize: suspend corona formula Dental Implant in midair, the root of the tooth of root pipe is arranged in comprising, thrust the tooth stake of root of the tooth root pipe and the corona on tooth stake top by dowel pin; Have the indent cavity in tooth stake upper surface, the cavity internal fixation has stressed elastic buffering mechanism, this stressed elastic buffering mechanism comprises a rhizoma sparganic pylon that is formed by the connection of gum elastic bar, on the rhizoma sparganic pylon, fixing ball on the horizontal rubber rods of each of lower surface, stressed elastic buffering mechanism also comprises one and connects thin bar, this connects thin bar and inserts solid laying respectively on the rhizoma sparganic pylon, on the lower surface and with the rhizoma sparganic pylon on, on two ball of each the ball contact on the lower surface, have the corresponding groove in vertical rubber rods position with the rhizoma sparganic pylon on the indent cavity inner wall of tooth stake, the vertical rubber rods of rhizoma sparganic pylon fixes in the groove of correspondence; The upper end that connects thin bar has screw thread, has the hole on the jaw of corona, and the upper end that connects thin bar is passed the hole on the corona jaw and is screwed with nut.
From maintenance form Dental Implant of the present invention, corona directly is not fixed in the tooth stake as existing Dental Implant, but being connected and fixed by stressed elastic buffering mechanism realization and tooth stake.The version that connects thin bar in the stressed elastic buffering mechanism, it is thinner to have determined that corona can be done, hat stake interface is risen to more than the height of contour line of tooth, make a hat stake interface expose, be convenient to brush teeth self-cleaning, effectively avoided existing plantation corona stake interface lower, with gingiva intersect being difficult to of being caused brush teeth self-cleaning, easily cause the drawback of gingiva inflammation;
On the drag form, corona is chewed compressing masterpiece suffered in the process and is used on the stressed elastic buffering mechanism, through connecting ball on the ball-rhizoma sparganic pylon upper and lower end face on thin bar-thin bar of the connection-gum elastic bar of rhizoma sparganic pylon is applied distraction force.Therefore, the suffered compressing power of corona is through stressed elastically damping device postpone, and the power on tooth stake, the root of the tooth of finally being applied to is distraction force but not compressing power, and this is a Dental Implant of the present invention and the very essential difference on the drag form of existing Dental Implant.
Suspention corona formula Dental Implant of the present invention; it is the mechanics principle that has utilized natural tooth; pass through buffer unit; make corona as suspension on the tooth stake because the tooth stake, root of the tooth is suffered is distraction force, compare with existing Dental Implant from having changed stressed form in essence; thereby suppress the generation of osteoclast; the generation of induced osteogenesis cell to the protection alveolar bone, prolongs Dental Implant and has produced the effect that is highly profitable in the intravital retention time of machine.Simultaneously, because the special structure (being connected with corona) that is connected and fixed between stressed elastic buffering mechanism and corona, make and be preced with an interface and risen, overcome existing Dental Implant existing defective and deficiency aspect the maintenance form by being connected thin bar.
Owing to have the indent cavity in the tooth stake, in tooth stake indent cavity, can place the pasty state that contains anti-inflammation drugs or paste (as toothpaste etc.).When the position of human body changes or is chewing, the anti-inflammation drugs slow release is come out, the periodontal of Dental Implant is had certain antiinflammation.

The specific embodiment
Suspend corona formula Dental Implant in midair, the root of the tooth 1 of root pipe is arranged in comprising, thrust the tooth stake 2 of root of the tooth root pipe and the corona 3 on tooth stake top by dowel pin; Have indent cavity 4 in tooth stake upper surface, the cavity internal fixation has stressed elastic buffering mechanism, this stressed elastic buffering mechanism comprises a rhizoma sparganic pylon 5 that is formed by the connection of gum elastic bar, on the rhizoma sparganic pylon, fixing ball 6 on the horizontal rubber rods of each of lower surface, stressed elastic buffering mechanism also comprises one and connects thin bar 7, this connects thin bar and inserts solid laying respectively on the rhizoma sparganic pylon, on the lower surface and with the rhizoma sparganic pylon on, two ball 8 of each the ball contact on the lower surface, on 9, have the groove 10 corresponding with the vertical rubber rods position of rhizoma sparganic pylon on the indent cavity inner wall of tooth stake, the vertical rubber rods of rhizoma sparganic pylon fixes in the groove of correspondence; The upper end that connects thin bar 7 has screw thread, has the hole on the jaw of corona, and the upper end that connects thin bar is passed the hole on the corona jaw and is screwed with nut 11.
In specific implementation process, according to existing technology root of the tooth is embedded on the dental bed, the dowel pin of tooth stake bottom is inserted in the root pipe of root of the tooth, so that tooth stake and root of the tooth are fixed, stressed elastic buffering mechanism is fixed in the indent cavity of tooth stake (also can place pasty state or the paste that contains anti-inflammation drugs in the cavity), again corona is placed in thin boom end, the nut of screwing on.Because the jaw face of corona is originally small as inner concave and nut size, nut can not influence chewing of Dental Implant.
If still have residual root of teeth on patient's dental bed, can utilize the root of the tooth of undesirable root as Dental Implant.
Dental Implant structure of the present invention also is applicable on the dens supporter.Because the change of stress morphology (dens supporter is finally suffered to be distraction force) can greatly reduce the compressing power of dens supporter to dental bed, reduces the misery that the patient wears the wearing and tearing of artificial tooth dental bed.
When Dental Implant of the present invention is used for labial teeth (being commonly called as front tooth), for facies labialis dentis before guaranteeing is attractive in appearance, high back was low before anterior teeth crown was made, and promptly the hat stake interface of labial teeth is asymmetric, the hat stake interface of labial teeth front is by last to the gingiva place, and the hat stake interface of back is by following.Like this, both guaranteed that preceding facies labialis dentis was attractive in appearance, and made the hat stake interface at labial teeth rear portion be convenient to brush teeth self-cleaning again.
