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.
Embodiment 1
As shown in Fig. 1 ~ 2: integral type Dental Implant, it for be made up of by laser weld implanting portion 1 and retainer 2 one overall; Its implanting portion 1 is made up of left and right two semicircular column 3,4, wherein, left half cylinder part 3 adopts medical titanium alloy product, and right half cylinder part 4 adopts porous tantalum product, its porosity is 60% ~ 62%, and left and right two semicircular column 3,4 realizes mutual being fixedly connected with particular by welding; The middle part of its retainer 2 is maximum gauge place 5, and circumferentially forms an annular recess 6 between the upper surface of the maximum gauge place 5 of retainer 2 and implanting portion 1; The top 7 of retainer 2 for two sides be the flat column of arc surface; The middle part appearance of implanting portion 1 is the trapezoidal thread 8 of 95 ° with thread form angle, and lower external equals the angular thread 9 of 60 ° with thread form angle, and the axial length ratio of this trapezoidal thread 8 and angular thread 9 equals 1.4; The overall length of this integral type Dental Implant is 13.5mm, and the length of 5 to the upper surface, maximum gauge place of its retainer 2 is 4mm, and the length of the upper surface of 5 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 5 of its retainer 2 is 4.5mm, and the diameter at its annular recess 6 place is 3.6mm; In two sides be the retainer 2 of the flat column of arc surface top 7 on corresponding artificial tooth is installed, namely achieve the implantation of artificial tooth.
In clinical practice, the annular recess 6 that unique structural design is formed, be convenient to human bone cell and be rapidly to its superficial growth, until filled, its bone tissue growth is obviously accelerated, and the restore cycle shortens greatly; Due to bone cell growth fill annulus, which form to Dental Implant naturally surround and fastening, it is rooted among alveolar bone firmly, and not easily get loose displacement.In addition, retainer 2 top 7 is the flat column of arc surface for two sides, installs after insertion artificial tooth through correspondence, is beneficial to the rotation after preventing artificial tooth from installing, more stable.
