Background technology
Successful Dental implant surgery can realize basic recovery nature tooth function.It is planted in the mid-early stage of implant tooth process
The fastness that the stability and later stage corona of body, base station and planting body connect is the key that the final success of tooth-implanting.And
The quality of dentistry implant and synosteosis is one of tooth-implanting success factor, i.e. the structure of planting body and elasticity modulus is to bone
Associativity plays important influence.Rational structure and matched elasticity modulus can make planting body and alveolar bone closely
It is combined together.But existing dental implant is big there are two the disadvantage is that stress concentration point is on alveolar bone and soft tissue interface, with
Time passage, alveolar bone horizontal plane can decline, and cause tooth implantation system deformation to loosen, so that dental implant and bone tissue
Binding force is insufficient, will reduce the stability of tooth implantation system.
For alveolar bone, the part below gum is made of dense bone, be below dense bone by with dense bone
It is formed compared to relatively soft cancellous bone.But existing planting body, typically entity planting body, Young's modulus are far above alveolus
Bone modulus, this will cause " stress-shielding effect ".At this point, bone regeneration around implant bone tissue will bear low load condition for a long time, will lead
Planting body is caused easily to loosen.And implant surface is sealing shape, and the Oesteoblast growth of alveolus can only overlay on dental implant
Appearance, synosteosis are poor.In addition, the Young's modulus of existing planting body immobilizes, mechanical structure poor performance.
