Description
Technical field:
The present invention relates to stomatology plantation recovery technique, the cylindrical tooth-planting system that adds compound circular-arc tooth structure of particularly a kind of flanged pin comprises implantation body and the base station that matches with it.
Technical background:
The sixties in 20th century, Sweden Gothenburg university
Professor has carried out having founded " synosteosis " theory of titanium, for theoretical basis has been established in the application of modern oral implantology about tooth-planting material and bone-implantation body's Study of Interface.The tooth-planting application technology is a most important part in the modern oral implantology.Extensively the carrying out and use the problem that has solved on a series of attractive in appearance and function that absence of tooth clinically brings of tooth-planting artificial tooth.
Yet the tooth in the anti-rotational structure of the profile of tooth of implantation body can produce local deformation because of bearing moment of torsion in operation, and this makes meets difficulty when base station is in place; Pointed shape implantation body external screw thread easily produces tangential force or shear stress when stressed on implantation body-synosteosis face, shearing stress can injure osseous tissue and then cause various problems; Bone resorption after plantation is repaired takes place, or the like.These all may cause planting the undesirable or repairing failure of repairing effect.
Summary of the invention:
Purpose of the present invention is exactly in order to overcome above-mentioned the deficiencies in the prior art, a kind of novel structure is provided, easily uses, anti-rotate effect is good, can bear more high pulling torque, stability height, no gap, the difficult mouth cavity planting body device that becomes flexible, can suppress bone resorption.
The present invention can reach by following measure:
The cylindrical mouth cavity planting body device that adds compound circular-arc tooth structure of a kind of flanged pin, comprise implantation body and base station with matching, implantation body is cylindrical, form by head, cervical region, interlude and afterbody, the head that it is characterized in that implantation body has flange, exterior is provided with little screw thread, and the interlude outer surface is provided with main thread, and afterbody is arc surfaced.
The flange of implantation body of the present invention head is made up of dome arc and concave arc transition; the flange top is the dome arc; bottom is a concave arc; the dome arc helps contacting with soft tissue; concave arc then easily contacts with osseous tissue, and between 0.15-0.4mm, concave arc mainly is easily to contact with osseous tissue to flange with respect to the protrusion amount of cervical region external diameter surface; the protection osseous tissue plays rounding off in addition.
The thread form of little screw thread of implant neck of the present invention is symmetric 90 degree trianglees, little screw thread will pass through Compact bone or top layer bone after implantation, can increase bonded area with this part osseous tissue, than the surface area of traditional smooth surface increase be twice above, when being performed the operation, the plantation dentist is easy to the custom planting hole, than prepare for screw thread hole simply and easier support hold, so stupefied avoiding causes plantation to be failed because of the improper one's mother's sister's Compact bone in preparation hole produces excessive compression.
The form of thread of the lip-deep main thread of interlude of implantation body of the present invention is asymmetric trapezoidal, near cervical region one side is 7-10 degree hypotenuse, near afterbody one side then is that radius is the circular arc between 0.3-0.4mm, pitch is between 0.72-1.2mm, be the integral multiple of little ridge distance, and the depth of thread from afterbody towards cervical region by deeply gradually shallow distribution, until withdrawing from interlude, with with alveolar bone in spongy bone combine closely, and when screwing in, produce suitable bone squeezing action.
Implantation body of the present invention inside is provided with and bonded combined hole of base station and connecting thread hole, combined hole is made up of internal conical surface and inner cylinder face, inner cylinder face is provided with 2-4 compound circular arc perforation, the toothed surface of the slyness that the cross-sectional profiles of compound circular arc perforation is made up of multi-section circular arc, the thickness of compound circular arc perforation is general to be determined according to the base station that is mated or the planting location of implantation body, compound circular-arc tooth and compound circular arc perforation can be realized rotate effect, and in implant operation, play the plate effect of twisting, be mainly used in implantation body is screwed in.
Base station of the present invention be provided with implantation body on internal conical surface and the outer conical surface and the external cylindrical surface of inner cylinder face corresponding matching, external cylindrical surface is provided with the compound circular-arc tooth that matches with compound circular-arc tooth, so that with base station be inserted in the implantation body, directed and closely be connected and fixed, in addition, after implantation body implants people's alveolar bone, be embedded in the bone, base station will stretch out and pass soft tissue, then base station stretch out the diameter at place will be less than the diameter of implantation body's head end, structure that Here it is " platform conversion ", the bone resorption after it can suppress to plant takes place.
The invention has the beneficial effects as follows: 1, little screw thread passes through Compact bone, can increase the contact area with bone, and is easy to customization, grasps and the hole is implanted in preparation, to avoid the causing excessive compression of Compact bone to cause the plantation failure because of the hole is too small.2, main thread gos deep into spongy bone and the depth of thread from shallow to deep, can obtain suitable bone squeezing effect, improves primary stability and also helps later stage stability.3, the asymmetric trapezoidal main thread thread form of You Huaing can reduce the generation of horizontal shearing stress, and the pitch of optimizing can obtain osseous tissue growth between better main thread tooth.4, head dimpling edge very easily obtains " putting in place " perception when implanting, and has suitable squeezing action further to improve primary stability to implanting the aperture.5, implantation body cooperates with taper seat between base station and can obtain fabulous sealing and stability.6, the arc toothed cylinder between implantation body and base station cooperates, and is not yielding, can bear bigger torsion, and anti-rotate effect is splendid.7, the platform transformational structure can suppress or eliminate bone resorption.
