Fig. 4 is the structure cutaway view of implantation body among the embodiment of the present utility model;
Fig. 5 is the vertical view of implantation body among the embodiment of the present utility model.
With reference to Fig. 3, Fig. 4 and Fig. 5, the implantation body 1 of present embodiment comprises cylinder body portion 11, frustum portion 12 and ball addendum cone afterbody 13 from top to bottom successively.Implantation body 1 is outside equipped with screw thread 111, and this screw thread 111 is gradually setting deeply from cylinder main part 11 to frustum portion 12 ends.Like this, the end of screw thread 111, directly present the awl nuclear morphology in the implantation body 1, and promptly the screw thread 111 of implantation body 1 presents taper in the column jacket.Cylinder body portion 11 upper ends are provided with one section threadless polished rod surface, make therewith that the contacted bone of part aperture presents simple cylindrical hole form, help stressed.
Implantation body's 1 whole compound contour structures of cylindrical, conical and spherical stack that adopts of present embodiment in implant operation, makes the doctor be convenient to the screw-in depth and the suitable bone decrement of control of perception implantation body 1.The afterbody of implantation body 1 is spherical, and boring will be used bone drill, and the end shape of bone drill also is an emphasis, must mate with implantation body's 1 afterbody.Implantation body's 1 afterbody that has is flat, and the bone drill end also must be flat so, but flat being difficult to made.So the end of the plantation bone drill that majority is such is sharp, " wedge angle " that produces in the bone hole can not coincide with implantation body 1 usually, thereby can form cavity.Studies have shown that too big cavity osseous tissue can not cover with wherein or need for a long time.Therefore, the afterbody of the implantation body 1 of present embodiment is arranged to " ball addendum cone " shape, its easiest and bone drill coupling.In addition, 111 ends of screw thread, directly be set to bore nuclear morphology, makes the screw thread 111 of implantation body 1 present taper in the column jacket, can increase suitable bone compression, to reach best implantation effect.And the upper end of cylinder body portion 11 is threadless polished rod, can make the bone hole that contacts with this part keep simple cylindrical hole form to be beneficial to stressed.Have again because base station 2 adopts conical surface sleeve type connected mode with implantation body 1, make base station 2 at the diameter of junction less than implantation body's 1 end face diameter, thereby can make base station 2 leave osseous tissue, thereby reduce or prevent bone resorption.
Fig. 6 is the overall structure sketch map of base station among the embodiment of the present utility model;
Fig. 7 is the structure cutaway view of base station among the embodiment of the present utility model
With reference to Fig. 6 and Fig. 7, the base station 2 of present embodiment comprises the platform awl 22 that is used for the handle body 21 that is equipped with implantation body 1 and is used to install artificial tooth, also is provided with a diameter between handle body 21 and the platform awl 22 and bores 22 big slightly short cylinders 23 than handle body 21 and platform.Handle body 21 is provided with and is used for cooperating to prevent the square tenon 211 (with reference to Fig. 4) of the regular polygon that base station 2 rotates relative to implantation body 1 with the square hole 15 of implantation body 1.Square hole 15 can be regular hexagon or dodecagon, so-called dodecagon be by two eclipsed regular hexagons around its center rotary shifted 30 ° of structures that stack is composited, square tenon 211 can be regular hexagon; When square hole 15 was square or octagonal, square tenon 211 can be square, and described octagonal formation principle is similar to dodecagon.In a word, the shape of square hole 15 and square tenon 211 is advisable can prevent also in the side's of being suitable for tenon 211 insertion square holes 15 that the two from relatively rotating.Handle body 21 also is provided with a conical surface 212, is used for carrying out sealing with the bellmouth 14 of implantation body 1 and cooperates, and enters in implantation body's 1 cavity and brings microorganism into to prevent foreign material, and then bring infringement to human body.
The platform awl 22 of base station 2 is positioned at handle body 21 tops, is shaped on one or two relative side plane 221 on platform awl 22, plays orientation or guiding function when being used to corona is installed.
The base station 2 of present embodiment adopts said structures, can form good binding with implantation body 1, can not produce leakage, and both junction surfaces have the platform transformational structure, can reduce or prevent bone resorption.
Fig. 8 is the cross-sectional view of screw thread among the embodiment of the present utility model.
In conjunction with Fig. 4 and Fig. 8, the implantation body 1 of present embodiment is provided with screw thread 111, the cross section of this screw thread 111 be 45 ° asymmetric trapezoidal, its half-angle near frustum portion 12 is 15 °, promptly when implantation body 1 vertically placed, this is trapezoidal to be 30 ° near the one side (top) of frustum portion 12 and the angle of horizontal plane; Another side (bottom) is 15 ° with the angle of horizontal plane then.
Because trapezoidal thread has good stable, to implantation body's 1 suffered axial force and radial force decomposition preferably can both be arranged, the top angle is big thereby length is long, with bone bigger bonded area can be arranged, and following angle is less, the shear stress components on the surface at this place, limit is reduced, so can bear bigger axial force.Because of tooth suffered main power or main component when chewing are axial forces, promptly along the power of implantation body's 1 axis direction, so the implantation body 1 of present embodiment has preferably synosteosis and chews the reasonability that shearing force is distributed.
Fig. 9 is the structural representation of cutting slot among the embodiment of the present utility model.
With reference to Fig. 9, present embodiment the frustum portion 12 terminal arrays of implantation body 1 be provided with at least one, four cutting slots 121 at the most, the trough line of cutting slot 121 is parallel with the bus of frustum portion 12.Cutting slot 121 is to be used for when implantation body 1 screws in the bone hole, and the female thread track that is fit to from tapping is firmly to be installed in implantation body 1 in the bone hole.Preferably, the flute profile angle is 90 °, so that the blade at cutting slot 121 places cuts osseous tissue and holds the chip that forms when cutting.
When implementing mouth cavity planting body device of the present utility model clinically, in the inner chamber of the implantation body 1 of can earlier the handle body 21 of base station 2 being packed into, after correct the cooperation, the stepped hole of bolt 3 by base station 2 inside screwed in the screwed hole 16 of implantation body's 1 inner chamber.Be screw-in and the back-out that makes things convenient for bolt 3, bolt 3 heads of the present utility model can adopt inner hexagonal hole, use corresponding hexagonal bottle opener to get final product.After base station 2 fixes with implantation body 1, implantation body 1 is screwed in the default bone hole.The female thread that the cutting slot 121 of frustum portion 12 ends of implantation body 1 can be fit to from the tapping size in the bone hole, thus mouth cavity planting body device firmly is installed in this bone hole.
In sum, mouth cavity planting body device of the present utility model adopts the technical scheme in the foregoing description, can realize the primary stability good when implantation body 1 implants and the synosteosis in later stage, make it have safety, reliable, good airproof performance, can reduce or prevent bone resorption, result of use is good and advantage such as long service life.
The above only is a preferred embodiment of the present utility model; be not so limit its claim; every equivalent structure transformation that utilizes this utility model description and accompanying drawing content to be done; directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
