Abstract
The invention disclsoes a magnesium alloy bracket applicable to dental transplantation. The magnesium alloy bracket is provided with an outer surface for fixing the magnesium alloy bracket into an alveolar hole and a cavity for containing a donor tooth; the magnesium alloy bracket is made of a magnesium alloy material and is gradually degraded along the growth of an alveolar bone. A thread is formed on the outer surface of the magnesium alloy bracket and the magnesium alloy bracket is fixed into the alveolar hole through the thread. By adopting the magnesium alloy bracket, the problem that the matching property of the alveolar hole and the donor tooth is poor can be solved, so that a transplanted tooth has good initial stability and guarantee is provided for later-period healing. Meanwhile, bone formation can be promoted through utilizing degradability and bone induction performance of a magnesium alloy, so that a newly growing bone can smoothly replace the magnesium alloy and the healing of the transplanted tooth is accelerated.
Description
Technical field
The correlation technique using and improving dental implant success rate of biodegradation magnesium alloy materials of the present invention, is related to dental implant
The technology that primary stability improves, particularly to a kind of magnesium alloy bracket being applied to dental implant.
Background technology
Dental implant refers to the tooth transplantation pulling out autologous or allosome in receptor jawbone, in order to repair the one of absence of tooth
The method of kind.With the development of organ transplantation technique, people continuously attempt to the method using autologous tooth and allosome dental implant, to expect
Reach the physiological reparation of absence of tooth.Compared with Dental Implant, planted teeth has excellent biomechanical property, and does not exist
The stress-shielding effect of titanium alloy implant, can preferably exercise physiological function with osseous tissue after being combined.Carry out dental implant it
Before need to prepare tooth socket, or original tooth socket is repaired so as to match with the root form of donor tooth.This behaviour
Need clinician to have skilled operation skill and take substantial amounts of Chairtime, but result is often unsatisfactory.Donor
The root form of tooth and the matching degree of tooth socket directly affect the primary stability of planted teeth, and indirectly result in the mistake of planted teeth
Lose rate.
On the other hand, with the development of material technology, biodegradation material is gradually applied to stomatology, joint or replacement
Traditional material, reaches the purpose simplifying operation, improving curative effect, has played important work in osteanagenesis and periodontal surgery treatment
With.However, presently, there are problem is that biodegradated polymer materal biomechanical strength is not ideal enough, degradation cycle mistake
Long, and there is no osteoinductive.
Content of the invention

Fig. 3 is the structural representation of the magnesium alloy bracket being applied to dental implant in the one of embodiment of the present invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to description literary composition
Word can be implemented according to this.
It should be appreciated that used herein such as " have ", "comprising" and " inclusion " term do not allot one or many
The presence of individual other element or a combination thereof or interpolation.
As shown in FIG. 1 to 3, the present invention provides a kind of magnesium alloy bracket being applied to dental implant, and this magnesium alloy bracket 1 has
Have for by its own outer surface 110 being fixed in tooth socket with the cavity 120 that is used for accommodating donor tooth 2, described magnesium alloy
Support 1 is made up of magnesium alloy materials, and gradually degrades with the growth of alveolar bone.
Magnesium ion is the cation that human body includes flow control four, is the important component of group adult body, is primarily present in skeleton
In, participate in the numerous metabolic activity of human body.The implantation body that magnesium alloy bracket is made can discharge in degradation process magnesium from
Son, magnesium ion has multiple special physiological functions, including kinase, suppresses dysautonomia excited, maintains nucleic acid structure stability,
Participate in albumen synthesis, muscle contraction and thermoregulation.Magnesium alloy catabolite in vivo is rich in calcium and phosphorus ionses, with biodegradation
Macromolecular material is compared, and assumes high mineralization attachment speed and bone amount increases around magnesium alloy.In addition, the degraded of magnesium alloy is produced
