Detailed Description

The present application is described in further detail below in conjunction with figures 1-3.

The embodiment of the application discloses an implant suitable for all-ceramic teeth. Referring to fig. 1, the implant adapted to the full porcelain tooth comprises a base 1 and a implant body 2, wherein the base 1 and the implant body 2 are in a round table shape, a large end face of the base 1 is abutted to a large end face of the implant body 2, a bolt 11 is arranged at the lower end of the base 1, a screw groove 21 is arranged at the upper end of the implant body 2, and the bolt 11 is adapted to the screw groove 21, so that fixation between the base 1 and the implant body 2 is realized.

The upper end of base 1 is equipped with inserted bar 12, and inserted bar 12 is vertical along the axis direction of base 1 to be set up, and inserted bar 12 is titanium alloy, and inserted bar 12 is cylindric, and the diameter of inserted bar 12 is gradually decreased progressively along the direction of keeping away from base 1, and inserted bar 12 is close to the one end of base 1 and is equipped with magnet piece 121, and inserted bar 12 passes base 1 and gets into inside planting body 2, and inserted bar 12 is equipped with a plurality ofly, and a plurality of inserted bars 12 set up around the axis circumference array of base 1.

It should be noted that, during actual manufacturing, after the bolts 11 are in threaded connection with the bolts 11, the abutment 1 is attached to the planting body 2, and then a jack penetrating through the abutment 1 and entering into the planting body 2 is formed, so that the insert rod 12 is adapted to the jack.

Referring to fig. 1, 2 and 3, the lower terminal surface of base 1 is equipped with annular gasket 13, annular gasket 13 is silica gel, annular gasket 13 passes bolt 11 and the lower terminal surface butt of base 1, annular gasket 13 is equipped with a plurality of archs 131, protruding 131 and annular gasket 13 take shape as an organic wholely, protruding 131 slope sets up, protruding 131 slope opposite direction with the screw thread on the bolt 11, protruding 131 is equipped with a plurality ofly, a plurality of archs 131 set up around the axle center circumference array of annular gasket 13, hinder taking place to rotate between base 1 and the planting body 2 through protruding 131, be favorable to further reducing the condition that takes place not hard up between planting body 2 and the base 1. ( Supplementary explanation: the annular gasket 13 is provided with a through hole for the inserted rod 12 to enter the planting body 2, so the annular gasket 13 cannot interfere with the inserted rod 12. )

The up end of planting body 2 is equipped with annular groove 22, and the cross-sectional area of annular groove is semicircle, and the groove depth of annular groove 22 is less than the height between the highest point and the minimum point of protruding 131, protruding 131 and the bottom butt of annular groove 22, and protruding 131 is close to one side of annular groove 22 and has arcwall surface 1311, through annular groove 22, makes the protruding 131 after the pressure place in annular groove 22 to the laminating between base 1 and the planting body 2.
