Abstract
The present invention belongs to a kind of cylindrical and conical titanium screw---spiral implant body for oral artificial tooth implantation. According to the different diameter size and length of titanium screw, the edge groove with different physical dimension and geometry is milled and biological hole with different diameter is drilled in the threaded position of the titanium screw. Said invented product is developed according to the anatomical physiology of bone and stomatology and clinical application in more than 3 years, so that it possesses excellent function, and safety and reliability.
Description
The present invention is the tooth spiral-shafted implant that is used in the department of stomatology manual tooth planting medical matters.Be that the screw thread position of cylinder, circular cone titanium screw has been milled the sword groove and has been drilled with biological hole, and make this spiral-shafted implant aspect mechanism property, security reliability, reached in the stomatology, to the theory requirement acquisition realization of spiral-shafted implant design three elements.Must verify through thousands of routine clinic trial over 3 years.
The present invention announces that according to World Health Organization (WHO) dental caries is that one of maximum three big diseases are endangering the mankind in the world.Manual tooth planting's body has more than 120 country in the world in development, and the manual tooth planting of regional economy developed country medical matters are universal in Europe, the United States.The Chinese government classifies canine implant as in the torch project of the 8th Five-Year Plan for national economic and social development, health ministry is these medical matters, actively promote to the whole nation with the high and new technology project, directly serve the anodontia patient that accounts for country's total population 1/5-1/3 (periodontal expectorant, wound just more) in addition.By the social value of above tooth implant, we want to be engaged in the development work of tooth spiral-shafted implant for doing the some contribution in these medical matters of bringing benefit to the mankind.
The present invention be referring to the Germany professor at Chengdu Huaxi Medical Univ teaching clinical operation video-tape, oral implantology, in the stomatologys such as the anatomical physiology of bone to the three elements requirement of spiral-shafted implant design, in the long-term investigation clinic operation, after actual effect.And obtain knowledge from scholar's experimentation: osseous tissue has piezoelectricity, produces current potential under external force, and current potential is to have collagen to produce, and it is collagen fiber that bone matrix is formed, and collagen produced the signal of telecommunication when external force was added on the bone.In the moulding one-tenth process of bone, the reflection of current potential pair cell produces specific effect, and nagative potential causes bone formation, and positive potential causes bone resorption.The regeneration of osseous tissue is mainly by periosteum, and after damaged bone was hindered, film inner layer cell division hypertrophy was filled in the wound, forms granulation tissue, then calcification and osteogenic tissue.The present invention is not beneficial to still in the clinic operation that dress is twisted, the time in the desmopyknosis, main is meets in the anatomical physiology of bone and the stomatology for the theoretical requirement of the three elements of spiral-shafted implant design, obtain to realize by the present invention recent decades, obtains 97 years the 5th Chinese patent technology fair gold medals and (demonstrate,prove number: 975914.1).For stomatologic development, also be the small contribution of point.
Technical solution of the present invention is: the screw thread position of cylinder, conical titanium screw, mill one or multi-channel according to diameter, how much row shapes are the sword groove of semicircle, square, triangle, quadrantal (spherical) triangle, and then according to screw thread position (comprising escape), length is bored the different biological hole of one or more diameters (Fig. 1-shown in Figure 4) with diameter.After sword groove cylinder, the whole machineds of conical titanium screw are finished, can need carry out vacuum titanizing (being spraying titanium slurry in the medical science) or not titanizing according to the user.
The present invention has following effect from coming the clinic trial checking 3 years more:
One, after boring on the alveolar bone, can directly be screwed into without tapping, sword groove titanium screw itself has the screw tap function.Avoided like product in clinical practice, not in place because of tapping, the existing unexpected phenomenon of back-outing firmly: the screw thread that distortion, fracture or the formation of bone wall are twisted by implantation body pulls (being stripped thread in the machinery), gives in doctor's art and causes difficulty, causes unnecessary misery to patient with operation.Sword groove titanium screw is directly to be screwed into alveolar bone after the boring, and compactness the best that the screw thread that the bone wall forms after being screwed into cooperates with implantation body is implanted the good stability at back initial stage, and primary guarantee successfully is provided for performing the operation.
Two, vertically there is the sword groove at the screw thread position (implant site) of titanium screw, and biological hole is laterally arranged, and tissue fluid obtains the sword groove and biological hole path is in time discharged, and has accelerated wound healing, and accelerating wound is second the ensureing successfully of performing the operation.
Three, the mechanical lock knot performance (the bone positioning key in sword groove such as the machinery of growing into, bone grow into the alignment pin in biological hole such as the machinery, sword groove and biological hole have increased the faying face of implantation body and bone again) of implantation body has been strengthened in grow into sword groove and biological hole of bone.Favorable mechanical lock knot performance has been strengthened steady position and fastness and the masticatory function of implantation body on alveolar bone, is guarantee loosening never after implantation body implants.
More than 3 meet fully in the stomatology the requirement of design spiral-shafted implant three elements, also be that present import and home-made like product do not have.
Be specifically described by most preferred embodiment and accompanying drawing thereof below, its accompanying drawing has four:
Fig. 1 is the front view of the cylindrical titanium screw of sword groove.
Fig. 2 is the sectional elevation of titanium screw shown in Figure 1.
Fig. 3 is the front view of the conical titanium screw of sword groove.
Fig. 4 is the sectional elevation of titanium screw shown in Figure 3.
In Fig. 1-4: the cylindrical titanium screw of 1 sword groove, 2 screw threads, 3 move back the sword groove, 4 biological holes, the conical titanium screw of 5 sword grooves, 6 screw threads, 7 escapes, 8 biological holes.
Embodiment:
Shown in Fig. 1-2, on the cylindrical titanium screw 1 of sword groove, screw thread 2 is arranged, in the screw length direction sword groove 3 is arranged, be drilled with biological hole 4 at the screw thread position.
