Description

The fixture of bone surface Dental Implant

Technical field

This utility model relates to medical appurtenance, a kind of specifically fixture of bone surface Dental Implant.

Background technology

At present, it generally is to adopt operating mode to implant that artificial tooth is implanted (canine implant), and the cylindrical shape of the root of the tooth of artificial tooth is in the alveolar bone of implanting patient's edentulous region, with this fixed denture.The artificial tooth of this kind structure in use has following deficiency:

When 1, patient's alveolar bone was narrow, the root of the tooth of plantation can not be embedded in the osseous tissue fully, can influence the integration between root of the tooth and the surrounding tissue, thereby influenced the fastness of root of the tooth.

2, patient's alveolar bone is crossed when shallow, implants the root of the tooth in the alveolar bone, can damage inferior alveolar nerve or maxillary sinus.

3, plant in the tooth process, the patient need bear certain misery, and after the artificial tooth implantation, its service life is subject to doctor's the surgical experience and the influence of patient body situation.

4, artificial tooth is fixed through single root of the tooth, and obscission takes place easily.

The utility model content

To the deficiency and the defective of above prior art, the purpose of this utility model is to provide a kind of fixture of bone surface Dental Implant.

The purpose of this utility model realizes through adopting following technical scheme:

A kind of fixture of bone surface Dental Implant; Comprise: fixed leg, this fixed leg are fixed in the middle part of " U " type titanium clamp, should offer square through hole on " U " type titanium clamp; This square through hole interconnects the surface that is netted and is arranged in " U " type titanium clamp; This square through hole is " funnel-form ", and it is positioned at the length of side of the length of side of the inboard square hole of " U " type titanium clamp less than the square hole that is positioned at " U " type titanium clamp outside, and the both sides of said " U " type titanium clamp also are provided with holding screw.

As the optimal technical scheme of this utility model, said fixed leg is provided with 1.5 ° tapering with the end that " U " type titanium clamp is connected, and this end is inserted in the hole of offering on " U " type titanium clamp.

As the optimal technical scheme of this utility model, said fixed leg is provided with rib with the junction of " U " type titanium clamp.

As the optimal technical scheme of this utility model, said fixed leg is the circular cone post, and its tapering is 1～3 °.

As the optimal technical scheme of this utility model, diameter of a circle is 2～3mm at the bottom of the said circular cone post.

As the optimal technical scheme of this utility model, said square through hole, its length of side that is positioned at the inboard square hole of " U " type titanium clamp is 0.5 mm, the length of side that is positioned at the square hole in " U " type titanium clamp outside is 1mm.

As the optimal technical scheme of this utility model, the thickness of said " U " type titanium clamp is 0.5～1mm.

Compared with prior art, the utlity model has following advantage:

1, artificial tooth fixes on patient's alveolar bone through " U " type titanium clamp, and steadiness is good, is applicable to various patients' different skeletons, and is narrow or cross when shallow at patient's alveolar bone, all can carry out the implantation of artificial tooth.

2, artificial tooth is implanted simply, and the patient's is painful less, and does not have higher requirement for doctor's surgical experience, as long as possess the doctor on surgery basis, can use.

3, " U " type titanium clamp and skeleton have compatibility preferably, and the long-time back alveolus influential point of bone that uses is grown in the square through hole of " U " type titanium clamp gradually, has improved the firmness of artificial tooth and alveolar bone greatly.

When 4, using this fixture, the making of patient Ya Mo can through the computer software three-dimensional reconstruction, alleviate patient's misery greatly through after the CT imaging than conventional art.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment this utility model is described further:

The specific embodiment

See also Fig. 1, be the front view of fixture first embodiment of this utility model bone surface Dental Implant.

This artificial tooth is implanted fixture, comprises the fixed leg 101 of fixed denture, and this fixed leg 101 is the circular cone post, and its tapering is 1～3 °, and diameter of a circle 103 is 2～3mm at the bottom of this circular cone post.

This fixed leg 101 is through the middle part of welding or one-body molded being fixed in " U " type titanium clamp 102; In use in order to prevent

fixed leg

101 and 102 fractures of " U " type titanium clamp, this fixed leg 101 is provided with rib 108 with the junction of " U " type titanium clamp 102.Thickness that should " U " type titanium clamp 102 is 0.5～1mm, and its both sides are provided with holding screw 104, when implanting artificial tooth, should " U " type titanium clamp 102 be fastened on patient's the alveolar bone of edentulous region, and fixes through holding screw 104.

See also Fig. 2 and Fig. 3, be respectively side view and the A-A cutaway view of Fig. 2 of the fixture of this utility model bone surface Dental Implant.

Should offer square through hole 105 on " U " type titanium clamp 102; This square through hole 105 interconnects the surface that is netted and is arranged in " U " type titanium clamp 102; This square through hole 105 is " funnel-form ", and it is positioned at the length of side 107 of the length of side 106 of the inboard square hole of " U " type titanium clamp 102 less than the square hole that is positioned at " U " type titanium clamp 102 outsides.

In this embodiment, comparatively preferably scheme does, said square through hole, and its length of side 106 that is positioned at the square hole of " U " type titanium clamp 102 inboards is 0.5 mm, the length of side 107 that is positioned at the square hole in " U " type titanium clamp 102 outsides is 1mm.

See also Fig. 2, be the exploded view of fixture second embodiment of this utility model bone surface Dental Implant.The difference of this second embodiment and above-mentioned first embodiment is; Said fixed leg 101 is provided with 1.5 ° tapering with the end 109 that " U " type titanium clamp 102 is connected; This end 109 is inserted in the hole offered on " U " type titanium clamp 102 (figure does not show), with U " type titanium clamp 102 will form the cold welding effect.Other structure division of this embodiment is said identical with first embodiment, just no longer gives unnecessary details at this.

Above-mentioned " U " type titanium clamp 102 adopts titanium; Its elastic modelling quantity is low; Compatible high with human skeleton; After being fixed in patient's alveolar bone, patient's alveolar bone can be grown in the square through hole 105 of " U " type titanium clamp 102 gradually, makes patient's alveolar bone and be somebody's turn to do " U " type titanium clamp 102 to combine together.

The preferred embodiment that the above is merely this utility model is not the practical range that is used for limiting this utility model; Every equivalence of doing according to this utility model changes and revises, and is all covered by the scope of this utility model claims.
