Abstract
A kind of mouth cavity planting body used for oral cavity Anodontia repair.For existing implantation body no matter cylindricality and root shape plant when running into harder tooth jawbone difficulty, existing implant surface screw thread be no matter triangle or trapezoidal all exist synosteosis face not enough and mainly come from large end stressed time angle be not the most perfect, neither be the most perfect in plantation and synosteosis along the cutting edge in implant axis line parallel direction problem.Adopt the surface topography that profile is made up of column section, taper section, arc, the screw thread form screw thread be positioned on taper section, arc is not equal angular trapezoidal thread, cutting edge from implantation body's small end in dextrorotation shape to large end, column section has several features of several equally spaced small arc-shaped groove.Easily, reasonable stress after plantation, provides better synestotic profile so a kind of object to reach the plantation when running into harder tooth jawbone.
Description
technical field
This utility model belongs to the mouth cavity planting body that in medical apparatus and instruments classification, oral cavity Anodontia repair uses.
background technology
Mouth cavity planting body has been applied to human body nearly 20 years, summary profile along with Clinical Experience progressively develops into cylindricality and root shape two class, cylindricality profile up and down equally thick, be generally applied to the wider occasion in alveolus position, Gen Xing implantation body upper end is large, lower end is little, profile is coniform, generally be applied to the occasion that alveolus position is narrower, also have profile to make sharp-pointed nose cone shape.Most surfaces has screw-like, and thread surface, based on triangle thread, from problem not enough in synosteosis face, has thread surface to be trapezoidal shape, but isosceles trapezoid screw thread neither be the most perfect under the bearing up-down force situation such as not.Implantation body's large end major part has very little spiral lamination, and effect is after planting for preventing.Some Species implant has cutting edge, in suitable implant axis line parallel direction.
utility model content
The purpose of this utility model is just to provide a kind ofly can be possessed Gen Xing implantation body and advantage but more have the well convenient plantation when harder tooth jawbone of self tapping ability than Gen Xing implantation body, be unlikely to that implantation body itself as sharp-pointed head conical implant is very long to such an extent as to the bone amount that needs are very thick just can complete plantation again, another order of the present invention be exactly implantation body thread surface bearing up-down force not etc. situation be issued to perfect stressed; The trend of cutting edge can provide better provides synestotic so a kind of implantation body.
This utility model reaches above object by following measure, implantation body's profile holds (1) to small end (13) by column section (3) by large, taper section (4), arc (5, 6) form, be positioned at taper section (4), arc (5, 6) screw thread on is not equal angular trapezoidal thread (7), the angle of trapezoidal thread (7) end bigger than normal (1) side (8) is less than the angle of little side (9), cutting edge (10) has vertical sword face (11) and arc surface (12), vertical sword face (11) is positioned at T-shaped screw thread (7) counterclockwise, and cutting edge (10) extends to large end (1) in dextrorotation shape from implantation body's small end (13).Arc (5,6) is made up of large arc (5) and little arc (6).Cutting edge (10) extends gradually shape from deep to shallow in dextrorotation shape to large end (1) from implantation body's small end (13), and column section (3) has several equally spaced small arc-shaped groove (2).
Mouth cavity planting body of the present utility model, by column section remain former cylindricality implantation body upper end steadily, the advantage of good seal, taper section remains primitive root shape implantation body and plants firm advantage, the arc increased improves the smooth plantation ability of implantation body at harder jawbone, improves the ability that implantation body tackles various complex under the prerequisite not increasing implant diameter.The angle that the angle of the large side of thread surface of implantation body is less than little side not only increases threaded bone combined surface area, more mainly when large end is stressed implantation body power to be passed to tooth jawbone more reasonable.The shape of cutting edge can better meet synosteosis, and right-hand screw shape is the increase in the length of cutting edge to the extension one of large end, and two is such rotation also more convenient plantations.

detailed description of the invention
The implantation body provided by Fig. 1 to Fig. 5, it implements feature 1 is the surface topography that profile is made up of column section, taper section, arc; Its implement feature 2 for the screw thread form screw thread be positioned on taper section, arc be not equal angular trapezoidal thread, the angle of this screw thread side bigger than normal is less than the angle of little side; Its implement feature 3 for cutting edge from implantation body's small end in dextrorotation shape to large end; Its enforcement feature 4 is several equally spaced small arc-shaped groove for column section has.
Claims (4)
