This utility model is provided with chamfering by the end face at self-aggressive dental implant, when being connected with base station, and implementation platform forwarding function.The double tapered design of body and root, can easierly carry out implant surgery, improves the primary stability of tooth plantation, at the uniform cutting slot of root, further improves this effect, and reduces to greatest extent bone loss.High-precision inner conical surface and the effect that plays sealing coordinating of base station, prevent micro-seepage.The locking of regular polygon hole and joint bolt, prevents the rotation of base station and tooth implant.Effectively prevent bone resorption, easily implant.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structural representation of looking up of the present utility model.
In figure:
1-body; 11-cervical region; 111-round recessed; 112-chamfering; 12-body; 13-root; 131-self tapping cutting slot; 14-bottom; 15-inner chamber; 151-rounding taper hole; 152-regular hexagon hole; 153-cylindrical hole; 154-internal thread hole.
Now the utility model is described in further detail with specific embodiment by reference to the accompanying drawings.
The specific embodiment
As shown in Figure 1 to Figure 3, be self-aggressive dental implant described in the utility model, mainly comprise body 1.
Body 1 is from top to bottom close to and is set to cervical region 11, body 12, root 13 and bottom 14 successively.The outer surface of body 1, through sandblasted and acid-etched surface treatment, forms the auxiliary layer of one deck enhancing and synosteosis performance.
The radially middle part of body 1 vertically arranges a uncovered inner chamber making progress 15, and inner chamber 15 is from top to bottom close to and is set to rounding taper hole 151 successively, regular polygon hole, and cylindrical hole 153 and internal thread hole 154, cylindrical hole 153 diameters are identical with the inscribed circle diameter in regular polygon hole.
The angle of the conical surface of rounding taper hole 151 is 90 °, can be also the unspecified angle of 15 ° to 120 °; The surface roughness of the conical surface is below 0.8 micron.
Regular polygon hole is regular hexagon hole 152, can be also octagon hole or equilateral triangle hole, or be other regular polygon hole.
This utility model is applied to the tooth plantation in oral cavity, as tooth implant, uses.
The effect of this utility model part-structure:
The round recessed that cervical region is offered, is conducive to the combination with alveolus cortical bone.
The circle chamfering that neck finish arranges, implementation platform shifts; Because neck finish is provided with a circle chamfering, thereby the diameter at the position that is connected with base station of tooth implant is greater than the diameter at the position that base station is connected with tooth implant, thereby the connecting portion that makes base station is to intracardiac moving in tooth implant, and load platform shifts.
Rounding taper hole coordinates and plays sealing function with base station.
The mutual positioning action of base station and tooth implant is played in regular hexagon hole, prevents that both from rotating mutually.
Cylindrical hole diameter is identical with the inscribed circle diameter in interior regular hexagon hole, uses with nail holding device clamping engagement.
The screw thread of internal thread hole matches with joint bolt size.
The double tapered design of body and root can guarantee to the certain pressure of alveolar bone, has strengthened the primary stability of plantation.
When alveolar bone is performed the operation, self-aggressive dental implant can reduce reaming flow process, reduces to greatest extent bone and runs off.This is because self-aggressive dental implant is provided with cutting slot and tapered tread, thereby there is the function that self tapping cutting function is equivalent to have screw tap, while holing on alveolar bone, just can save the step of reaming and tapping, during implantation, mechanical hole reaming does not need expansion so large, has naturally reduced bone number of dropouts.Concrete implementation procedure is: machine drilling, to behind certain aperture, does not need to carry out reaming again and tapping, can directly screw in tooth implant, thus by itself cutting slot and screw thread is realized reaming and tapping is positioned on alveolar bone.
By platform, shift the fine motion reducing between base station and tooth implant, prevent that micro-seepage of antibacterial and the bone of periphery run off, and improve the success rate of plantation.
This utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not departed to spirit and scope of the present utility model, if within these changes and modification belong to claim of the present utility model and equivalent technologies scope, this utility model is also intended to comprise these changes and change.
