Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, in an embodiment of the present invention, a safe and firm oral implant includes an implant 2 and an abutment 3, the implant 2 is implanted into an alveolar ridge 1 downward through a screw-fit manner, the abutment 3 is in screw-fit connection with the implant 2, and an artificial dental crown is correspondingly mounted on the abutment 3.

Implant 2 and base station 3 all adopt pure titanium material to make, implant 2's external diameter is 3.4mm, 4.2mm or 4.1mm, implant 2's length is 6.0mm, 9.5mm, 11mm, 11.5mm or 13mm, implant 2's screw thread interval is 1.25mm and the screw thread tooth height is 0.3 mm.

The inside of planting body 2 is provided with grafting cavity 4 and the transmission cavity 5 of integrative intercommunication, is vertical state and disposes screw body 8 with screw-thread fit form in transmission cavity 5, the bottom end cross-section of screw body 8 sets up to the isosceles triangle shape of inversion, and it has displacement passageway 6 and the corresponding chuck pole 7 that disposes in displacement passageway 6 to link up horizontally respectively on the bottom left and right sides lateral wall of transmission cavity 5, the outside terminal surface of chuck pole 7 sets up to vertical plane structure, the medial surface of chuck pole 7 sets up to slope terminal surface 701 structure and slope terminal surface 701 and cooperatees with the triangle-shaped waist 801 of screw body 8 bottom, the top of screw body 8 has the circumference diameter that boss and boss are greater than screw body 8, and the bottom left and right sides position punishment of boss do not punishment of an integrative extension has a buckle arch 803, buckle arch 803 under the arch 803, inwards seted up straining cavity 9 on corresponding planting body 2, the degree of depth of straining cavity 9 is greater than the protruding length of buckle, and still placed a buckle arch 10 in the bottom corner position department of grafting cavity 4 respectively, the buckle arch 10 sets up to the top of the buckle arch 802 that sets up the buckle tongue 802 "the top wall top contacts up to the boss top wall in the hexagonal groove 804 that supports the buckle arch 802" the buckle is supported the boss 804, and supports the boss 10 in the boss, and sets up the boss top of the boss 802 that supports the boss.

In practical operation, before the abutment 3 and the artificial crown are assembled, after the implant 2 is implanted into the alveolar ridge 1, a dentist uses an inner hexagonal wrench to screw the screw body 8 downwards, because the inner side end surface of the chuck rod 7 is set to be the inclined end surface 701 and the inclined end surface 701 is matched with the triangular waist surface 801 at the bottom end of the screw body 8, when the screw body 8 gradually descends towards the bottom end, the triangular waist surface 801 at the bottom end of the screw body 8 applies an outward pushing force to the inner side end surface of the chuck rod 7 to enable the two chuck rods 7 to synchronously and continuously displace outwards, when the outer side end surface of the chuck rod 7 is inserted into the alveolar ridge 1, the whole implant 2 can be firmly fixed in the alveolar ridge 1 by using the locking effect of the chuck rod 7, so as to ensure the firmness of the whole implant, and in the process, one end of the buckle gasket 10 is matched with the buckle protrusion 803 to be clamped into the concave cavity 9, the other end of the buckle gasket 10 is automatically abutted against the abutting groove 802, if the buckle gasket is not automatically abutted, the abutting is also feasible through manual adjustment, the whole device is completely locked by utilizing the matching of the buckle bulge 803, the buckle gasket 10 and the buckle cavity 9, then the abutment 3 and the artificial dental crown are installed, and the whole operation flow is finished.

Through the utility model discloses a safe firm type oral cavity kind tooth, the structure to traditional planting body 2 improves, it is equipped with the screw body 8 to add, displacement channel 6, dop pole 7, the boss, buckle arch 803, buckle gasket 10 and straining cavity 9, under the drive fit of part, can will utilize the effect of locking of dop pole 7 to fix whole planting body 2 firmly in alveolar ridge 1, guarantee the firmness of whole kind of tooth with this, recycle buckle arch 803, buckle gasket 10 dies with the cooperation of straining cavity 9 in order to guarantee that whole device locks completely, avoid the screw body 8 to deviate from, this oral cavity kind tooth's fastness has further been ensured, safety has been ensured, reasonable in design is ingenious, better commercial using value has, and is suitable for being generalized to use.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
