Technical Field

The invention relates to the technical field of dental implant medicine, in particular to a maxillary sinus region implant used in dental implant.

Background

Titanium metal implant obtains extensive application on oral implantation artificial tooth along with the continuous improvement of science and technology, and planting tooth clinical practice for many years proves its validity and practicality human development civilization's progressive nature, because the restriction of jaw, planting tooth's steadiness always is the problem that clinical needs to solve, and the method of improving planting tooth's steadiness at present is to increase bone volume, changes the planting position of implant and changes implant mechanism osseointegration surface treatment technique, nevertheless because the restriction of bone volume height, the implant is restricted by area of contact after combining with jaw, and the steadiness is hardly improved again.

The dental implant according to the present invention referred to below refers only to the implant root implanted in the jaw of a patient, and does not include a covering body, an abutment, and a dental crown.

Disclosure of Invention

The invention aims to provide a dental implant aiming at the defects of the prior art after the invention patent of lifting a reamer in a maxillary sinus of a dental implant.

The purpose of the invention is realized by the following technical means:

have the external screw thread, the upper end opening, inside cavity, the external screw thread distributes in the outside and the lower part of dental implant, inside cavity divide into the upper portion and revolves the installation section of twisting section and lower part, the installation section has the internal thread, be equipped with fore-and-aft guide way, have in the installation section with internal screw thread complex screw rod and with guide way complex slider, the screw rod top surface is equipped with and revolves the portion of twisting, be equipped with the elastic wire on the slider, screw rod and slider pin joint, there is the through-hole on the lateral wall of dental implant, the elastic wire end can pass the through-hole, the screw rod drives slider longitudinal movement, the dental implant can be worn out to the elastic wire, increase and the jaw's after combining area of contact.

In a preferred scheme, the outer side of the dental implant is provided with a spiral flute.

Preferably, the cross section of the screwing section is hexagonal, the cross section of the mounting section is circular with a notch, and the diameter of an inscribed circle of the hexagonal is larger than that of the circular.

Preferably, the mounting section has two symmetrical guide grooves, and the slider has two symmetrical projections which are respectively embedded in the guide grooves.

Preferably, the screw-on portion is a groove or a protrusion having a hexagonal cross section.

According to the preferred scheme, the number of the elastic wires is three, the number of the through holes is three, the inner opening of each through hole is formed in the bottom of the mounting section, the lower portion of the dental implant is in an inverted cone shape, and the outer opening of each through hole is formed in the upper end of the cone shape.

In the preferred scheme, the elastic wire is connected with the sliding block in two modes, one mode is that one end of the elastic wire is fixed at the bottom of the sliding block, and the other end of the elastic wire is inclined outwards or bent; the other type is that the bottom of the sliding block is provided with a groove, the lower part of the groove is provided with a beam, one end of the elastic wire winds around the beam for a circle, and the other end of the elastic wire is bent outwards.

Compared with the prior art, the invention has the following obvious advantages: the main design has the elastic wire that can wear out dental implant, increases the area of contact of implant and jaw after implant and bone combination, has formed the additional stake root of implant and has strengthened the anti lateral torsion power of the steadiness of dental implant.
