Description

Implant device for segmented implantation

Technical Field

The invention belongs to the field of implants, and particularly relates to the field of implant devices for segmented implantation.

Background

The traditional implant surrounding soft tissue molding depends on the healing base station to contact with the soft tissue, the soft tissue can generate corresponding shape according to the shape of the healing part, and after the soft tissue is attached to the base station processed by micro-roughness, the soft tissue attachment relation can be generated under certain conditions. However, the traditional oral implantation device has poor biocompatibility, cannot realize instant stable connection, and causes poor initial stability of the oral implantation device in the oral cavity, the healing component needs to be repaired, the healing component needs to be taken down during repair, and when the implant position is transferred, the adhesion relation is damaged to a certain extent. After the permanent abutment is brought in, the final repair is difficult to form tight and airtight biological closure, and bacteria can easily invade to cause infection and inflammation. The implantation mode designed based on the traditional oral implantation device has obvious defects, one-time implantation cannot be realized, wounds and infection are easily caused, mechanical properties and biocompatibility cannot be considered, and the operation effect cannot be ensured. And the upper part of the traditional abutment is connected with the dental crown and the abutment by using the adhesive, the adhesive can be damaged by removing the adhesive by using an instrument, and a part of the adhesive is remained at the intersection part of the dental crown and the gum, so that the situation that the inflammation caused by bacterial breeding is difficult to avoid is relatively easy to form.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve unable disposable implantation device and cause the bacterium to invade the problem that arouses infection and inflammation easily, the utility model provides an implant device of segmentation implantation, including implant, healing base station, central screw, crown screw and the basement that has the external screw thread, the implant passes through central screw fixation is in healing base station one end, the basement passes through the crown screw fixation is in the healing base station other end.

Preferably, the mounting hole is formed in the top of the implant, a threaded hole is formed below the mounting hole, the cross section of the mounting hole is polygonal, the bottom of the healing base platform is installed in a matched mode with the mounting hole, the head end of the healing base platform is provided with a placing cavity used for placing the head of the central screw, a through hole is further formed in the healing base platform, the placing cavity is communicated with the through hole, the diameter of the placing cavity is larger than that of the through hole, and the central screw penetrates through the through hole and is fixed with the threaded hole in a matched mode. The shape of the mounting hole is a multi-directional structure, so that the implant is prevented from rotating.

Further, the head of central authorities ' screw has seted up the fixed slot, the step hole has been seted up on the basement, the step hole from the top down includes locking portion, connecting portion and placing portion in proper order, locking portion is used for placing the head end of crown screw, placing portion is used for placing the central authorities ' screw head end, locking portion with placing portion's size all is greater than connecting portion, crown screw pass the step hole with fixed slot threaded connection. The crown screw fixes the base on the central screw, and the bottom surface of the base is attached to the upper surface of the healing abutment.

Preferably, the base is circumferentially provided with a groove and is used for mounting porcelain teeth. The grooves increase the friction force with the porcelain teeth, so that the porcelain teeth are precisely combined with the base. The porcelain teeth and the substrate are fixed through the adhesive, the adhesive is coated on the side wall of the substrate, the substrate is positioned above the gum, the problem of adhesive residue is avoided, and soft tissues can be kept relatively stable.

Furthermore, two sides of the substrate are also provided with limit blocks. The limit block limits circumferential movement of the porcelain teeth mounted on the substrate.

Has the advantages that: the utility model discloses keep the relative stability of soft tissue adhesion relation, need not to take out the healing base station, can not breed the bacterium and arouse the inflammation, need not the secondary and implant, reduced the risk of operation wound and pain and infection, improved mechanical properties and biocompatibility.

Detailed Description

Example one

The utility model provides an implant device that segmentation was implanted, includes implant 1, healing base station 2, central screw 6, crown screw 10 and the basement 3 that has the external screw thread, implant 1 passes through central screw 6 is fixed healing base station 2 one end, basement 3 passes through crown screw 10 is fixed healing base station 2 the other end.

Mounting hole 9 has been seted up at planting body 1 top, mounting hole 9 below is equipped with screw hole 8, the cross sectional shape of mounting hole 9 is the polygon, the bottom of healing base station 2 with the cooperation installation of

mounting hole

9, 2 head ends of healing base station are offered and are used for placing the chamber 14 of placing of 6 heads of central screw, through-hole 15 has still been seted up on healing base station 2, place chamber 14 with through-hole 15 intercommunication and its diameter are greater than through-hole 15 diameter, central screw 6 passes through-hole 15 with the cooperation of screw hole 8 is fixed.

The head of central authorities ' screw 6 has seted up fixed slot 7, the step hole has been seted up on the basement 3, the step hole from the top down includes locking portion 11, connecting portion 12 and placing portion 13 in proper order, locking portion 11 is used for placing the head end of hat screw 10, placing portion 13 is used for placing the 6 head ends of central authorities ' screw, locking portion 11 with placing portion 13's size all is greater than connecting portion 12, hat screw 10 pass the step hole with fixed slot 7 threaded connection.
