Detailed description of the invention
Be below the utility model preferred embodiment, and be not intended to limit protection domain of the present utility model.
Embodiment 1
As shown in Fig. 1 ~ 2: implant component is planted in integration, it is the entirety be made up of implanting portion 1 and retainer 2; Bottom 8 appearance of its implanting portion 1 is provided with the angular thread 3 that thread form angle equals 60 °, and middle part appearance is provided with the trapezoidal thread 4 that thread form angle equals 100 °, and the axial length ratio of its trapezoidal thread 4 and angular thread 3 equals 1.4; The bottom 8 of its implanting portion 1 adopts porous tantalum product, and its porosity is 65%; The top 5 of its retainer 2 is flat column, and middle part is maximum gauge place 6, and forms an annular groove 7 vertically between the upper surface, top of this maximum gauge place 6 and implanting portion 1; The overall length that implant component is planted in this integration is 13.5mm, and wherein, the length of 6 to the upper surface, maximum gauge place of retainer 2 is 4mm, and the length of the upper surface of 6 to the implanting portion, maximum gauge place 1 of retainer 2 is 1.5mm, and the length of implanting portion 1 is 8mm; The diameter at the maximum gauge place 6 of retainer 2 is 4.5mm; Be 3.8mm with the diameter of retainer 2 bottom of the junction, upper surface of implanting portion 1; The middle and upper part of its retainer 2 and implanting portion 1 adopts medical titanium alloy one-body molded, and is realized and being fixedly connected with of bottom, implanting portion 1 by welding; Retainer 2 top 5 correspondence of flat column installs artificial tooth, namely achieves the implantation of artificial tooth.
In clinical practice, the annular groove 7 distributed vertically that unique structural design is formed, be beneficial to human bone cell and be rapidly to growth in groove, until filled, its bone tissue growth is obviously accelerated, and the restore cycle shortens greatly; Because the growth of osteocyte is filled, define to tooth-implanting prosthese naturally surround and fastening, it is rooted among alveolar bone firmly, and not easily get loose displacement.In addition, the angular thread 3 of bottom, implanting portion 1 improves self tapping, implants more efficient and convenient, in the middle part of it, trapezoidal thread 4 or rectangular thread improve the mechanical strength of structure, improve stress performance, substantially increase the success rate of plantation, effectively improve clinical application effect.
