Abstract
The invention discloses a bionic dental implant and a main root thereof. The dental implant comprises a main root and an abutment. The main root comprises a retention root part at the lower end thereof and an abutment part at the upper end thereof. The dental implant further comprises at least one secondary root. The side face of the main root includes grooves with the number the same as that of the secondary roots. The inner surfaces of the grooves are matched with the external surfaces of the secondary roots such that the auxiliary roots can be inserted at the side of the main root seamlessly. The abutment is at the upper parts of the main root and the secondary roots and used for connecting the main root with the secondary roots. The beneficial effect of the invention is that the dental implant can be directly implanted in a tooth nest with the tooth extracted and used as the dental implant of artificial tooth root after the affected tooth is extracted as the dental implant has the oblate or fork appearance characteristics of the natural tooth root.
Description
Technical field
The present invention relates to a kind of tooth implant, specifically, relate to a kind of have a secondary root can be the human body cacodontia be implanted to the exodontia nest at once after pulling out in and the main root that serves as the tooth implant of artificial tooth root and be exclusively used in this tooth implant.
Background technology
At present at dentist's circle widely used one garden post or garden taper tooth implant, because its form greatly differs from each other with the oblate form and bifurcated (or fusion) form of natural root of the tooth, thereby can't after being pulled out, natural teeth be implanted at once in the exodontia nest so that fill up the exodontia nest fully, so, under existing tooth implant condition, the tooth implant after the exodontia is implanted a great problem that is still dentist circle at once.The inventor's a number of patent application is 200710048850.9, name is called " a kind of bionic tooth implant " application for a patent for invention formerly, though created many bionic tooth implant forms, but still can't realize that tooth implant imitates the natural tooth root form fully, so that can plantation at once after exodontia.
Summary of the invention
The objective of the invention is can not the natural front tooth of imitation true to nature at existing tooth implant oblate root of the tooth profile or the bifurcated root of the tooth profile shortcoming of natural backteeth, a kind of bionic tooth implant has been proposed, this bionic tooth implant has natural tooth root " oblate " or " bifurcated " resemblance, thereby can and serve as the tooth implant of artificial tooth root the human body cacodontia is implanted to the exodontia nest at once after pulling out in.
In order to realize that for achieving the above object, the technical solution adopted in the present invention is: a kind of bionic tooth implant, comprise main root and base station, described main root comprises the maintenance root that is positioned at its lower end and is positioned at the abutment portion of its upper end; Also comprise at least one secondary root; The side of described main root has and the identical groove of secondary radical amount, the inner surface of described groove and the outer surface of secondary root be complementary so that secondary root can gapless embedding main root sidepiece; Described base station is positioned at the top of main root and secondary root and main root and secondary root is linked together.
For base station, main root and secondary root are further firmly linked together, the lower end of above-mentioned base station is extended with a maintenance bar, and the cross section of described maintenance bar dwindles from top to bottom gradually; The inside of described secondary root has a fixed hole, and the outer surface of the inner surface of described fixed hole and the degree of depth and maintenance bar and length are complementary so that the maintenance bar can embed in the fixed hole of secondary root.
For main root and secondary root are further firmly linked together, the lower end of above-mentioned secondary root has screw thread that the screw thread with the inner surface of groove is complementary so that secondary root can be rotated with the side in main root.
As a preferred embodiment of the present invention, on the basis of such scheme, has a groove on the lower surface of described base station; The upper end of the abutment portion of described main root and the upper end of secondary root are extended with a main root projection and secondary root projection respectively, after secondary root and main root are in place, main root projection and secondary root convex to form the boss that a groove with aforementioned base station is complementary, and groove is interior to link together main root, secondary root and base station three so that boss can embed.
As another preferred embodiment of the present invention, on the basis of such scheme, has a through hole on the end face of described base station; The inside of described main root has a fixed hole, and the lower end of fixed hole has screw thread; Also comprise a base station bolt, the through hole that described base station bolt is passed down through base station is rotated with on the screw thread of the fixed hole of main root main root, secondary root and base station three is linked together.
Another object of the present invention provides a kind of main root that is exclusively used in above-mentioned bionic tooth implant, described main root comprises the maintenance root that is positioned at its lower end and is positioned at the abutment portion of its upper end, its side has and the identical groove of secondary radical amount, the inner surface of described groove and the outer surface of secondary root be complementary so that secondary root can gapless embedding main root sidepiece.
The method for implantation of above-mentioned bionic tooth implant and main root thereof is the same with existing multi-rooted tooth implantation body, all adopts and axially rotate the method for implanting after preparing the bone hole on the dental bed.
The invention has the beneficial effects as follows: the bifurcated root of the tooth form of the oblate root of the tooth of the natural front tooth of imitation that (1) is true to nature and natural backteeth, and the method for implantation that adopts is commonly used at present axially rotating into and screw thread maintenance mode, thereby the exodontia nest can be implanted and fill up fully to natural teeth after being pulled out at once, obtain the maintenance of good dental bed top and inside and outside both sides cortical bone simultaneously and obtain firm effect of powerful initial stage, it is stressed to bear a heavy burden at once.(2) use of base station maintenance bar, maintenance bolt, be linked to be firm stressed integral body with major and minor with base station, closing three when not only static is one, and it is also whole firm under the stress, simultaneously, oblate and Y-shaped is planted body can effectively decompose the stressed of implantation body, makes at once the stressed at once possibility that becomes after the plantation.(3) " emulation " effect to the natural tooth root form of forming of the combination by major and minor, present multi-rooted tooth implantation body can't realize, starts and plants backteeth was especially planted and obtained high success rate at once after pulling out the beginning after the exodontia at once.
