The porous tantalum product of above-mentioned porosity, can meet this and plant the mechanical property requirements of tooth body in structure, 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 cervical region of planting tooth body and the afterbody of porous tantalum product can make bone grow 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 shape.
Above-mentioned retained abutment head is cuboid, and with artificial tooth corresponding matching, can further increase anti-axial-rotation.
The quantity of above-mentioned spring is preferably two, and for arranging up and down.Above-mentioned slide block is provided with two grooves of arranging up and down corresponding to mounting spring place.
Further, the above-mentioned tooth body of planting is rhabodoid, and the diameter of its afterbody is short compared with cervical region or middle part.The tooth body of planting of this structure setting has been realized with alveolar bone and being firmly connected, and has the effects such as the sinking of further preventing.
The above-mentioned tooth body inside of planting is provided with groove, and it is the gas thread of 55 ° that this groove side is provided with tooth form angle; Described retained abutment bottom is threaded rod, this threaded rod and the gas thread corresponding matching of planting the setting of tooth body internal recess side.
Further, above-mentioned cervical region and afterbody of planting tooth body, realizes and being fixedly connected with of above-mentioned middle part of planting tooth body through bonding or welding respectively.Its connected mode is solid and reliable.
In this utility model, retained abutment and artificial tooth laminating closely, have been played well anti-moving axially, and anti-loosening and effect that come off; Its outer surface of planting tooth body middle part is provided with gas thread, has strengthened with the firm of alveolar bone and has been connected; It plants tooth body and retained abutment, and to adopt tooth form angle be the gas thread Corresponding matching of 55 °, sealing and good stress performance, easily produce self-locking, avoid impurity to enter in screw thread, and further plant that the non-stress position of tooth body---cervical region and afterbody are set to porous tantalum product, well meet and ensured its mechanical property, also greatly increased the biocompatibility of its structural entity simultaneously, improve service life and implanted comfort level, having increased stability and anti-verticity after this artificial prosthesis is implanted.
