Abstract
The invention relates to an oral implant with a cylindrical horn mouth and compound circular-arc tooth structure, which is applied to the filed of oral implanting and repairing. The head of the implant is in a horn mouth shape, the small end of the implant is connected with a cylindrical main body, and a cavity is arranged below the conical surface of the horn mouth of the head and comprises a conical surface, a compound circular-arc tooth-shaped inner cylindrical surface and the like; and asymmetrically, trapezoidal outer threads are arranged on the outer surface of the main part of the implant, the threads have unequal depths from one side close to the head to the tail. Therefore, the implant can realize the application of a gingival-puncturing implantation mode, the head of the implant is positioned in the soft tissue of a gingival, the outer threads of the implant have the function of proper bone extrusion when the implant is implanted, and the implant is tightly matched with a base table so as to provide favorable sealing performance, orientation and rotary resistance.
Description
Technical field:
The present invention relates to stomatology plantation recovery technique, particularly a kind of mouth cavity planting body with the cylindrical horn mouth compound circular-arc tooth structure.
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:
A kind of mouth cavity planting body with the cylindrical horn mouth compound circular-arc tooth structure is made of head, main body and afterbody, it is characterized in that implantation body's head is bell mouth shape, and implantation body's main body is cylindrical, and implantation body's afterbody is arc surfaced.
The upper surface of implantation body of the present invention head is a taper seat, the lateral surface of planting the body head is the horn-like outline that is made of circular arc and straight line, when doing implant surgery, taper seat will be under the gingiva appropriate location or be on the gingiva face, the bell mouth shape head will be on the alveolar bone in the gingival soft tissue, therefore mainly will be applied to wear gum surgical repair case.
Main body is provided with gradually dark trapezoidal external screw thread from top to bottom among the present invention, its form of thread is asymmetric trapezoidal, thread form is a 7-10 degree hypotenuse near head one side, near afterbody one side then is that radius is the circular arc between 0.3-0.4mm, pitch is between 0.72-1.2mm, pitch is the integral multiple of numerical value 0.24, numerical value 0.24 is from a kind of pitch of the miniature screw thread of being created by the present inventor, the external screw thread degree of depth afterbody from head one side direction and is distributed from light to dark, the depth value at shallow place is 1/3 to 1/2 of the bosom degree of depth, therefore, this implantation body has the core diameter of thread and is little conical awl nuclear characteristics.
Implantation body of the present invention inside is provided with combined hole and the connecting thread hole with base station, combined hole is made up of the internal conical surface and the face of cylinder, the face of cylinder is provided with 2-4 compound circular arc perforation hole, the tooth-shape structure 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 determined according to the base station that is mated or the planting location of implantation body.
Implantation body of the present invention will cooperate special-purpose corona base station in actual applications, and the inner cylinder of internal conical surface and band compound circular arc perforation will combine with the respective face on the base station, screwed hole will be used for tying with fastening screw thrust, fixing base station usefulness.
The invention has the beneficial effects as follows: 1, adopt and wear gum formula structure, only need once operation can finish implantation, can reduce patient suffering, doctor's operation risk, and reduce the operation cost.2, external screw thread can obtain suitable bone squeezing effect from shallow to deep, so can improve primary stability and help later stage stability.3, the asymmetric trapezoidal external screw 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 ridge.4, implantation body cooperates with taper seat between base station and can obtain fabulous sealing and stability.5, 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.6, wear the gum structure and can make implantation body and base station land, thereby can suppress bone resorption away from alveolar bone.
Description of drawings:
Fig. 1 is a kind of structural representation of the present invention.
The A-A cutaway view of Fig. 2 Fig. 1.
Fig. 3 is that the B of Fig. 1 is to enlarged drawing.
Labelling among the figure: head 1, main body 2, afterbody 3, taper seat 4, horn-like outline 5, internal conical surface 6, compound circular arc perforation 7, screwed hole 8, the face of cylinder 9, trapezoidal external screw thread 10, circular arc 11,12,13,14,15.
Be described further below in conjunction with accompanying drawing.
As shown in drawings, a kind of band cylindrical horn mouth compound circular-arc tooth aperture chamber implantation body, by head 1, main body 2 and afterbody 3 constitute, it is characterized in that implantation body's head 1 is horn-like, implantation body's main body 2 is cylindrical, implantation body's afterbody 3 is arc surfaced, the upper surface of implantation body's head 1 is a taper seat 4, the lateral surface of planting body head 1 is the horn-like outline 5 that is made of circular arc and straight line, when doing implant surgery, taper seat 4 will be under the gingiva appropriate location or be on the gingiva face, and the bell mouth shape head will be on the alveolar bone in the gingival soft tissue, therefore mainly will be applied to wear gum surgical repair case.
