Description
Technical field
This utility model belongs to artificial dental implantation body technical field, relate to one and there is bioactive Dental Implant, particularly relate to a kind of can after exodontia immediate implant and initiatively induction between the root of the tooth and tooth socket osseous tissue of Dental Implant, form synestotic Dental Implant.
Background technology
Dental Implant (dental implant) is called as the 3rd secondary tooth of the mankind, has become modern stomatologic significant technology.Modern dentistry planting technology full-fledged is the synosteosis theory (osseointegration, or be called Integrated implant) proposed the sixties in last century based on the father Branemark of Dental Implant.American Dental implantology can be defined as synestotic: normal reconstruction bone directly contacts with implantation body, grow into, and the based model for load duration of Neng Shi implantation body conducts and is dispersed in osseous tissue without the soft tissue can seen under light microscopic.
Modern tooth implant mainly adopts the inorganic material such as titanium or pottery to be made by machining, material surface has good biocompatibility, but be difficult to build continual and steady regeneration inducing bioactivity, so the quick healing after implantation body's implantation needs good primary stability, that is, during implantation, implantation body just can form the direct of enough areas with surrounding socket bone and contacts.For this reason, carry out when the healing of 3-6 crescent nest osteanagenesis is good after tradition implant operation is generally arranged in exodontia, and need after implanting to embed or static healing 3 months, to obtain good Osseointegrated implants, row second operation again, connects top dentures structure.Which increase the misery of patient, and extend operating time.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, one is provided to have the bioactive immediate implantation teeth of root of the tooth, this Dental Implant has the artificial tooth root of bionical natural teeth root of the tooth cementum structure, possesses autonomous bone induction and regeneration reconstruction ability, can in the rear immediate implant of exodontia, simulate natural planted teeth periodontal healing process, solve the problem that agomphosis Complicated primary is rebuild.
For this reason, this utility model provides following technical scheme: one has the bioactive immediate implantation teeth of root of the tooth, it comprises pure titanium or titanium alloy implant core, described pure titanium or titanium alloy implant core comprise bizet and root, and the connecting portion of described bizet and described root has the step of 0.8-1mm, the center of described bizet has screwed hole, artificial corona is fixed by the screw inserting described screwed hole, the outer surface of described root has screw thread, by described screw thread dispersion bite stress, the outer surface of described root also has one deck artificial tooth root bioactive layer, described artificial tooth root bioactive layer wraps up described root and is wrapped up within it by described screw thread.
Further, wherein, described artificial tooth root bioactive layer is made up of calcium phosphate magnesium-SP biological active collagen material.
Again further, wherein, the thickness of described artificial tooth root bioactive layer is 3mm.
Superiority of the present utility model is: adopt pure titanium or titanium alloys for tooth implant core, possess good biocompatibility, machining property, Mechanics of Machinery character, can provide the bulk strength of similar natural teeth for immediate implantation teeth; Bizet can adopt screw to connect the artificial corona of corresponding form according to agomphosis position, is suitable for the agomphosis reparation of different parts; Tooth root subpackage is by calcium phosphate magnesium-SP biological active collagen material, and this material has the cemental 26S Proteasome Structure and Function of simulation natural teeth root of the tooth, makes biomimetic prosthetic root of the tooth.This Dental Implant can after exodontia immediate implant, there is the periodontal biological activity of autonomous induction Regeneration of Alveolar Bone reconstruction, significantly can shorten agomphosis repair time, improve success rate.
Accompanying drawing explanation
Fig. 1 is the enlarged drawing with the bioactive immediate implantation teeth of root of the tooth of the present utility model.
Detailed description of the invention
Describe detailed description of the invention of the present utility model in detail below in conjunction with accompanying drawing, the content of detailed description of the invention is not as the restriction to protection domain of the present utility model.
This utility model relates to one and has the bioactive immediate implantation teeth of root of the tooth, this Dental Implant has the artificial tooth root of bionical natural teeth root of the tooth cementum structure, possesses autonomous bone induction and regeneration reconstruction ability, can in the rear immediate implant of exodontia, simulate natural planted teeth periodontal healing process, solve the problem that agomphosis Complicated primary is rebuild.
Fig. 1 shows the enlarged drawing with the bioactive immediate implantation teeth of root of the tooth of the present utility model.As shown in Figure 1, of the present utility model have the bioactive immediate implantation teeth of root of the tooth and comprise pure titanium or titanium alloy implant core.Root implantation body core is formed through intermetallic composite coating by pure titanium or titanium alloy.Described pure titanium or titanium alloy implant core comprise bizet 1 and root 2, and the connecting portion of described bizet 1 and described root 2 has the step 3 of 0.8-1mm.Wherein, described bizet 1 is for connecting artificial corona, and described root 2 is for planting in alveolus.
The center of described bizet 1 has screwed hole 4.Like this, described implantation body core can fix artificial corona 8 by the screw 7 inserted in described screwed hole 4.The outer surface of described root 2 has screw thread 5.Can bite stress be disperseed by described screw thread 5, and contribute to bioactive layer described later and be fixed on better on described root 2.The outer surface of described root 2 also has one deck artificial tooth root bioactive layer 6.Described artificial tooth root bioactive layer 6 wraps up described root 2 and is wrapped up within it by described screw thread 5.By described root of the tooth bioactive layer 6, make this Dental Implant have autonomous bone induction and regeneration reconstruction ability, in the rear immediate implant of exodontia, natural planted teeth periodontal healing process can be simulated.
In this utility model, preferably, described artificial tooth root bioactive layer 6 is made up of calcium phosphate magnesium-SP (Arg-Pro-Lys-Pro-Gln-Gln-Phe-Phe-Gly-Leu-Met-NH2) biological active collagen material.Owing to using the self-curing composite based on calcium phosphate magnesium, it is made to have good material compatibility and histocompatibility, have the following advantages: be easy to moulding processing (comprising integral material profile, internal stent structure and rack surface form etc.), material with adjustable intensity, controllable degradation rate, several functions loads (comprising as stem cell transplantation carrier, biotic factor/medicine loading and slow-released carrier etc.), has bone guided and bone-inducting active concurrently.For solution Dental Implant periodontal healing problem, there is unique advantage.Simultaneously, the introducing of SP (Arg-Pro-Lys-Pro-Gln-Gln-Phe-Phe-Gly-Leu-Met-NH2) biological active collagen, make it can build autonomous induction periodontal healing environment, can regenerate by inducing endogenous Periodontal Supporting Tissue after implanting, complete artificial material to reconstruct to the conversion of autologous tissue, and the periodontal attachment supporting structure that final formation is stable.
Most preferably, the thickness of described artificial tooth root bioactive layer 6 is 3mm.
