Description
Technical field
The utility model relates to a kind of tooth implant.
Background technology
Tooth implant, is to be implanted into by way of operation in the upper mandibular at human body agomphosis position, treats its hand
After art wound healing, the device repairing artificial tooth is installed at an upper portion thereof.The key of tooth-implanting is planting body part, planting body
Part is equivalent to the root of the tooth of dermal tooth, and fixing for whole tooth serves vital effect；The biology of planting body part
Compatibility quality, whether can with lived knitting together with, only bone and planting body grows together, and could be total to if determining it
With the various strength supported from occlusion.
Titanium or titanium alloy material, as important bio-medical material, has high mechanical properties, high tenacity and excellent resisting
Fatigue behaviour, is widely used in the joint of human body, tooth, the replacement of Gu Deng sclerous tissues.But titanium and titanium alloy are implanted to human body
In generally there is biologically active difference, the problem such as bond strength is low, healing time length.After human body implanted by metal material, due to for a long time
Fluid environment is on active service and may result in metallic surface corrosion, even make metal ion enter injected organism tissue and make injected organism tissue
Rotten.In order to improve the biologically active of medical titanium metal, promote the combination of itself and body bone tissue, at present conventional method be
Material surface hydroxyapatite coating layer in plasma spraying；But coating is low with basal body interface bond strength, easily ftracture, and control
The treatment time is long, and bone is long with the healing time of planting body, leverages its using effect.Therefore medical titanium surface is activated
Modification, improves the binding ability with human body hard tissue and is significant.
Utility model content
The purpose of this utility model is intended to solve existing tooth implant, and to there is face coat low with basal body interface bond strength,
Biologically active difference and the problem of bone healing time length, and a kind of tooth implant providing.
A kind of tooth implant accelerating knitting, it includes plantation root of the tooth and base station；The outside setting of described plantation root of the tooth
External screw thread and three leaf swords, externally threaded surface configuration bioactive layer；Described plantation root of the tooth top inside offer fixing hole and
Internal thread, internal thread is positioned at the bottom of fixing hole；The bottom of described base station arranges external screw thread, and external screw thread is suitable with internal thread；
The middle part of described base station is the cylinder of the regular hexagonal section of arc section transition；The top of described base station is hollow cylinder.
Principle of the present utility model:
The utility model arranges external screw thread in the outside of plantation root of the tooth, and uses special fixture fixing plantation root of the tooth, then
Carrying out differential arc oxidation process in the electrolytic solution, obtaining bioactive layer on externally threaded surface, bioactive layer has well raw
Thing compatibility, can guarantee that osteocyte vigor does not reduces, and after tooth implant is implanted and fits tightly between bone tissue, and gap is very little,
Postoperative adhesions closes wound, and making have the tooth implant of bioactive layer can more preferable and skeleton structure in human oral cavity
In conjunction with healing stage is short, forms the knitting interface not having soft tissue gap.
The beneficial effects of the utility model:
It after the utility model is planted root of the tooth and base station adaptation, is completely embedded, will not produce relative rotation；At plantation root of the tooth
Outside external screw thread and three leaf swords are set, preferably control bone-cutting amount and there is very strong retention and stability；Pass through
Differential arc oxidation process, obtains bioactive layer, bioactive layer and the boundary with fine biocompatibility on externally threaded surface
Face bond strength is high, difficult drop-off, and can accelerate the speed of knitting, the masticatory function of fast quick-recovery tooth, mitigates operation
Risk.
