The self-locking implant tooth can tightly connect the retention base table with a tooth crown in real time, is also convenient for implanting or discharging substances, has a reasonable structure and has good biocompatibility.

Description

A kind of self-locking Dental Implant

Technical field

This utility model relates to oral cavity canine implant, relates in particular to a kind of self-locking Dental Implant.

Background technology

What at present oral tooth implantation operation adopted plant, and dental structure mostly includes plants tooth body, retained abutment and artificial tooth.Plant tooth body and imbed in advance after dental bed, its top refills and establishes retained abutment, and this retained abutment exposes to dental bed surface and artificial tooth is installed, and realizes the implantation of artificial tooth with this.Wherein, between retained abutment and artificial tooth, be usually simple plug-in type connected mode, the anti-axial-rotation of this connected mode is poor, and has the problem that connects not firmly, easily becomes flexible, comes off.

In addition, there is certain defect in existing Dental Implant on structure arranges, and causes it after implantation, can not wait sclerotin weakness planting tooth body bottom, then add as bone grafting material, biotic factor etc. other to increase the material of planting tooth steadiness.Meanwhile, existing Dental Implant also exist mechanical property and biocompatibility poor, after long-time use, there will be repulsion with tissue, and affect the problems such as its service life.

Utility model content

The purpose of this utility model is to provide a kind of self-locking Dental Implant, and this Dental Implant can closely be connected retained abutment with corona in real time, and being convenient to import increases the material of planting tooth steadiness, rational in infrastructure, and has good biocompatibility concurrently.

The purpose of this utility model is achieved in that

A kind of self-locking Dental Implant, it includes plants tooth body, retained abutment and artificial tooth, it is characterized in that: described retained abutment head is provided with groove on one side, in this groove, is provided with spring, and spring arranged outside has slide block; In described artificial tooth, correspondence is provided with the caulking groove that described slide block is installed; The described tooth body of planting adopts porous tantalum product, and its porosity is 60% ~ 70%, and this is planted tooth body inside and is provided with the perforation running through up and down.

The porous tantalum product of above-mentioned porosity, can meet this and plant tooth body and plant the mechanical property requirements in dental structure at this, is closely connected reliably with alveolar bone to realize it.This porous tantalum product can adopt the preparations such as foam dipping method, die pressing.Through the discovery that studies for a long period of time: adopt the tooth physical ability of planting of porous tantalum product that bone is grown into and the structure of growing in forming, thereby organically combine as a whole with body bone tissue, in greatly having improved biocompatibility, also well meet its mechanical property, improve service life and implanted comfort level, having increased stability and anti-verticity after artificial prosthesis is implanted.

Above-mentioned slide block, is excellently less than the right-angled trapezium body of lower surface area for upper surface area.This slide block also can be set to the object that other sides such as right angle trigonometry body are inclined-plane, or the object of other shapes.

Above-mentioned retained abutment head is cuboid, and with artificial tooth corresponding matching, can further increase anti-axial-rotation.

The inner surface of tooth body of planting of above-mentioned perforation middle and upper part is provided with regular screw threads; Above-mentioned retained abutment bottom is threaded rod, this threaded rod with described in plant the regular screw threads corresponding matching that the inner surface of tooth body arranges, be fixedly connected with the self-locking that realizes the two, and good stress performance.

This utility model will be processed with groove and be provided with spring on retained abutment head one side, the slide block that configuration can be movable in this groove again, so that its mating reaction and play the fixation that is similar to latch dead bolt---along with artificial tooth is toward lower slider, promote slide block Compress Spring moves in groove, after artificial tooth moves into place, slide block falls into the caulking groove on artificial tooth, now by the effect of spring, make slide block can keep with artificial tooth on caulking groove laminating closely, thereby play well anti-axially movable effect, and anti-loosening and effect that come off; And further will plant tooth body itself and adopt porous tantalum product, well meet its mechanical property, also greatly increase the biocompatibility that this plants dental structure simultaneously, improved service life and implanted comfort level, increased stability and anti-verticity after this artificial prosthesis is implanted.In addition, in tooth body, be provided with the perforation running through up and down planting, realize sclerotin weakness such as planting tooth body bottom has been introduced, has been evenly distributed on to other materials of planting tooth steadiness to increase such as bone grafting material, biotic factor, and increased the stability being connected with sclerotin, make its be set to porous tantalum product to plant tooth body better compatible.

Detailed description of the invention

Be below this utility model preferred embodiment, and be not intended to limit protection domain of the present utility model.

As shown in Figures 1 to 3: a kind of self-locking Dental Implant, it includes plants retained abutment 2 and the artificial tooth 3 that tooth body 1, head are cuboid; On its retained abutment 2 head one sides, be provided with square groove 4, be provided with a spring 5 in this groove 4, spring 5 arranged outside have slide block 6; Slide block 6 is less than the right-angled trapezium body of lower surface area for upper surface area; The interior correspondence of its artificial tooth 3 is provided with the caulking groove 7 that slide block 6 is installed; It is planted tooth body 1 and adopts porous tantalum product, and its porosity is 60% ~ 70%, and plants tooth body 1 inside and be provided with the perforation 8 running through up and down; The inner surface of tooth body 1 of planting of these perforation 8 middle and upper parts is provided with regular screw threads; Its retained abutment 2 bottoms are threaded rod 9, and this threaded rod 9 and the regular screw threads corresponding matching of planting 1 inner perforated 8 surface, the middle and upper part settings of tooth body, be fixedly connected with the self-locking that realizes the two; This head is the retained abutment 2 of cuboid, adopt medical titanium alloy make, and with artificial tooth 3 corresponding matching, realized the implantation of artificial tooth.

By being processed with groove 4 and being provided with spring 5 on retained abutment 2 head one sides, configuration can be at the slide block 6 of these groove 4 interior activities again, so that it cooperatively interacts and plays the chimeric self-locking action that is similar to latch dead bolt---along with artificial tooth 3 is toward lower slider, promote slide block 6 Compress Springs 5 to the interior movement of groove 4, after artificial tooth 3 moves into place, slide block 6 falls into the caulking groove 7 on artificial tooth 3, now by the effect of spring 5, make slide block 6 can keep with artificial tooth 3 on caulking groove 7 laminating closely, thereby play well anti-axially movable effect, and anti-loosening and effect that come off.And be further provided with the perforation 8 running through up and down planting tooth body 1 inside, realize sclerotin weakness such as planting tooth body 1 bottom has been introduced, has been evenly distributed on to other materials of planting tooth steadiness to increase such as bone grafting material, biotic factor, and increase the stability that is connected with sclerotin, make it and be set to porous tantalum product to plant tooth body 1 better compatible.
