Abstract
The invention belongs to a dental micro-implant anchorage and particularly relates to a combined micro-implant anchorage; the invention solves the problem that a head and a screwing part of the prior micro-implant anchorage can not be separated. The combined micro-implant anchorage comprises an anchorage body; the anchorage comprises the screwing part; the lower end of the screwing part is provided with a V-shaped slot; and the tip is provided with tapping screw thread. The combined micro-implant anchorage is characterized in that the upper end part of the screwing part is sheathed with a neck strap; the screwing part above the neck strap is connected with a cap body; and a silicon rubber case is sheathed outside the cap body. The invention has the beneficial effects the installation is convenient, the stability is high, and the combined micro-implant anchorage is good for soft tissue to be attached and closed and is good for changing and cleaning.
Description
Technical field
The invention belongs to the little implant anchorage of dental, be specifically related to a kind of combined micro-implant anchorage.
Background technology
Little implant anchorage is a kind of novel anchorage means effective and that the less patient of depending on of energy cooperates of stablizing.Use implant anchorage and can realize that the tooth that conventional orthodontic treatment means can not realize moves, a lot of difficult and complicated illness are successfully treated becomes possibility.
Existing implant anchorage such as Chinese patent 200520014483.7 and 200320124802.0 all are integrative-structures, and it comprises head and screw-in portion, and the diameter of head is greater than the diameter of screw-in portion, so that locate on mucous layer.Head and screw-in portion are indissociable, have caused many inconvenience.
Summary of the invention
The invention provides a kind of novel combined micro-implant anchorage.
The present invention adopts following technical scheme to realize:
Combined micro-implant anchorage comprises the anchorage body, and the anchorage body comprises screw-in portion, screw in the subordinate end and have V-shaped groove, tapping screw thread is established in the termination, it is characterized in that screw-in portion upper end is with neck ring, be connected with the medicated cap body, the external sheathed silica gel sheath of medicated cap in the screw-in portion of neck ring top.
Screw-in portion top has application of force groove.
Have three sections continuous threads on the screw-in portion excircle, the pitch of three sections screw threads from bottom to top from large to small.
The present invention has following beneficial effect:
1, termination portion is a tapping screw thread, screws in the oral cavity jawbone easily, but and self-locking, be difficult for loosening.
2, three sections of screw-in portion excircle screw threads that the natural from large to small transition of pitch from the bottom up connects, it is simple that implantation body is implanted, and also helps to improve the primary stability of implantation body.
3, screwing in the V-shaped groove of subordinate's end can inducting osseous tissue, and the endosteal implant of growing into can be put into the degradable biological material in the V-shaped groove.
4, the neck ring made of dense form ceramic material or plastic material is beneficial to soft tissue and adheres to and seal, and is beneficial to and changes and clean.
5, the medicated cap body on neck ring top and the screw-in portion that stays mucosa outside be by being threaded, and realizes that superstructure can change.
6, the medicated cap external body covers with silicone rubber sleeve, is beneficial to the protection mucosa.
7, screw-in portion top has application of force groove, can also can remove or screw in spanner or handler with machine.
Description of drawings
Fig. 1 is a structural representation of the present invention
Fig. 2 is the plan structure sketch map of screw-in portion
Among the figure: 1-tapping screw thread, 2-V shape groove, 3-screw-in portion, 4-neck ring, 5-medicated cap body, 6-silica gel sheath, 7-application of force groove
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present invention is described further.
Combined micro-implant anchorage comprises the anchorage body, and the anchorage body comprises screw-in portion 3, and screw-in portion 3 bottoms have V-shaped groove 2, and V-shaped groove 2 can inducting osseous tissue, and the endosteal implant of growing into has the degradable biological material in the V-arrangement ditch.
Tapping screw thread 1 is established in the termination, but self tapping cutting screws in the oral cavity jawbone easily, but and self-locking, be difficult for loosening.
Screw-in portion 3 upper ends are with neck ring 4, and the neck ring that dense form ceramic material or plastic material are made is beneficial to soft tissue and adheres to and seal, and are beneficial to and change and clean.
Be connected with medicated cap body 5 in the screw-in portion 3 of neck ring 4 tops, medicated cap body and the screw-in portion that stays mucosa outside be by being threaded, and realizes that superstructure can change.
Medicated cap body 5 outer sheathed silica gel sheaths 6 are beneficial to the protection mucosa.
Screw-in portion 3 tops have application of force groove 7, can also can remove or screw in spanner or handler with machine.
Have three sections screw threads on screw-in portion 3 excircles, three sections thread pitch not only can make implantation body implant simply from bottom to top from large to small, also help to improve the primary stability of implantation body.
Claims (3)
