Description

A kind of tooth implant with horizontal root

Technical field

This utility model relates to a kind of tooth implant, specifically, relates to a kind of tooth implant with the horizontal root in the horizontal implantation dental bed.

Background technology

The multi-rooted tooth implantation body that vertically implants in the dental bed is extensive use of in the world, be called " tooth implant " as name, number of patent application is that the Chinese invention patent application of CN200480021203.3 discloses the multi-rooted tooth implantation body in a kind of vertical implantation dental bed, in the low-density spongy bone of the tooth implant maintenance of the type in dental bed, thereby the stressed effect at once of tooth implant is relatively poor with long-term steadiness.The name that the applicant proposes is called " a kind of bionic tooth implant and method for implantation thereof ", number of patent application be CN200710048850.9 a kind of multirooted teeth implantation body that has comprised parent root and daughter root is then disclosed in first to file, implantation body compares with multi-rooted tooth, this implantation body has strengthened the contact area of tooth implant in dental bed, the part daughter root maintenance of tooth implant has improved tooth implant stressed effect and long-term steadiness at once in highdensity cortical bone.But, because the contact surface of the high density cortical bone in above-mentioned multirooted teeth implantation body and the dental bed is big inadequately, its stressed effect at once should be inadequately, be not enough to after plantation is finished, bear at once masticatory force, thereby the firm power that is not enough to provide powerful makes bone regeneration around implant jawbone osseous tissue in not being subjected to or being subjected to less the interferential environment of external force, finishes the reconstruction of osseous tissue smoothly and form physiological with implantation body combining in implant surface.Thereby the single or multirooted teeth implantation body of prior art after plantation is finished, all needs to wait for the some months time, after the reconstruction for the treatment of osseous tissue is finished, corona could be installed make implantation body stressed, is not enough to " stressed at once after the plantation " of realizing that industry is dreamed of.

Summary of the invention

The purpose of this utility model is at the deficiency that has single or multirooted teeth implantation body now, and a kind of tooth implant with horizontal root is provided, and it not only can vertically obtain sclerotin maintenance power, but also can be in the maintenance power that laterally obtains more high density cortical bones.

For achieving the above object, the technical scheme that this utility model adopted is: a kind of tooth implant with horizontal root, comprise: a parent root, the lower end of described parent root is the maintenance root with screw thread, described maintenance root can vertically be implanted in the dental bed, and the cross section of maintenance root bottom diminishes downwards gradually; At least one horizontal root, the two ends of described horizontal root have screw thread, described horizontal root can laterally be implanted in the dental bed, has at least one shrinkage pool on the periphery of horizontal root, has the screw thread that the screw thread with the lower end of parent root is complementary in the described shrinkage pool, described shrinkage pool can be fixed together parent root and horizontal root by the mode that is threaded with the maintenance root lower end of parent root, also has the hole in many ways that is used for location and installation in the end face of described horizontal root, also has screw in the described hole in many ways.

For maintenance power at the more high density cortical bones of horizontal acquisition, also has screw in the hole in many ways in the end face of above-mentioned horizontal root, and also comprise: at least one horizontal root medicated cap, described horizontal root medicated cap is positioned at the end of horizontal root, structure in the form of sheets, inboard on the horizontal root medicated cap is extruded with the body in many ways of a coupling of hole shape in many ways in the end face with horizontal root, and the center of described body in many ways is through with a consistent screw of screw in the hole in many ways with horizontal root; At least one screw, described screw can run through and be fixed together after screw in the screw at body center in many ways and the hole in many ways is threaded horizontal root medicated cap and horizontal root.

The beneficial effects of the utility model are embodied in following: in the prior art vertical root (parent root or daughter root) bear from the vertical and horizontal of corona stressed after, after at first offsetting part through the absorption of dental bed top high density cortical bone, remainder then is delivered to the dental bed inside with low-density spongy bone.And the horizontal root that this utility model tooth implant comprises, closely be connected to form " in length and breadth " attitude tooth implant with vertical root of the prior art (parent root or daughter root), bear from the vertical and horizontal of corona stressed after, after stressed at first the absorption counteracting part through dental bed top high density cortical bone, remainder then transmits and decomposes on the horizontal root, and horizontal root is delivered to the high density cortical bone with power by its two ends decomposition, further, after installing horizontal root medicated cap additional, horizontal root medicated cap can decompose the both sides that are delivered to the high density cortical bone with power again.Like this, all of this utility model tooth implant are stressed all to be transmitted and is decomposed on the high density cortical bone of dental bed, thereby the stressed effect at once of this utility model tooth implant is good with long-term steadiness, after plantation is finished, tooth implant also can not be subjected to displacement under stress and influence bone and integrate, thereby it is stressed at once corona to be installed at once after plantation is finished, and avoids patient to wait for the some months time again.
