Production forms synosteosis, and planting body is made all to suffer restraints on circumferencial direction and axial direction, it is firmly fixed to alveolus very much
In bone, plantation success rate is provided.
The utility model has the advantages that 1, due to the presence of screw thread planting body and bone tissue contact surface area can increase, be conducive to improve
Osseointegrated implants intensity；Biological feature study is carried out for a whole set of implant system, neck portion design dovetail groove is except increase implantation
When screw thread cutting and self tapping effect, the mechanical self-latching effect of screw thread can increase its initial planting stability, while increase plantation
Body and bone tissue retain implant neck bone tissue to greatest extent, subtract in region of stress concentration, that is, cortex bone EDGE CONTACT area
Few unnecessary loss of bone tissue, reinforces the early stage maintenance of cortex bone, the success rate and long-term effect of implant denture is improved, with it
His planting body multi-segment thread is compared, using one-part form (continuous) variable diameter screw thread in planting process can directly guide blood it is thin
Born of the same parents are sought connections with from bottom to top to implant neck screw thread, and one-part form (continuous) variable diameter screw thread can guarantee unobstructed blood after plantation, are had
Effect improves bone tissue nutrient and provides, and faster forms synosteosis.Conventional segmental screw thread cannot guarantee two sections of blood in first time
Between contact fusion, and one-part form variable diameter screw thread very good solution this problem, Machine Design that this programme comprehensively considers
And be machined, the joinery and its construction of the dovetail groove type of innovation is used in Machine Design, for designing upper no any difficulty；Machine
It is only necessary to make subtle adjustment on cutter again volume production processing can be realized in tool processing, the processing of cutter is very convenient, right
Any problem be also not in processing volume production.
2, traditional planting body shape is angular thread mode, and osteocyte and implant surface directly contact, and needs osteocyte
It is firmly adsorbed in implant surface, requires high for surface treatment in this way, planting body is contoured to accommodation groove and dovetail
The mode that slot combines, synosteosis do not need osteocyte when being formed and are adsorbed onto implant surface, can carry out " card in this way
Connect " (bone cell growth enters in dovetail groove), osteoblastic proliferation is buckled in dovetail groove inflexibly with the calcified bone being differentiated to form,
It can produce the joinery and its construction mode used on similar ancient building, very strong mechanical lock clamp force can be formed, surface treatment is required
