Description

Implant Providing a Middle Abutment

The present invention relates to an implant having an intermediate pier, and more particularly to an implant having an intermediate pier connecting the screw and the upper pier.

Among the technologies for inserting replacement implants that replace the teeth of the human body, the technology related to implants has made rapid progress in recent years. Implant is a substitute that recovers when the tissue of the human body is lost, but in the dentist, it means an artificial tooth implant.

Implant is a cutting-edge technology that replaces the missing tooth root and replaces the artificial tooth root composed of titanium with no rejection to the human alveolar bone to fix the artificial tooth and restore the original function of the tooth.

1 shows the teeth of a patient who is going to have an implant. As shown, in recent years there is an increasing number of patients with gum disease due to incorrect brushing. When the implant is performed in a patient with severe periodontitis in which the alveolar bone is largely lost, the upper screw portion of the implant is exposed, and the implant is not planted firmly, and foreign matter or bacteria penetrate into the exposed surface to cause inflammation.

If the thickness of the alveolar bone to be implanted is low and the density is low, the support of the implant is not firmly supported and the alveolar bone is broken, so there are many difficulties in the procedure.

Therefore, when the thickness of the alveolar bone is thin, a method of GBR (Guided Bone Regeneration) is proposed in which an artificial alveolar bone is formed by supplementally inserting a paste. In the GBR procedure, as shown in FIG. 2, the titanium membrane 1 is fixed to the alveolar bone by a screw 3 to prevent the paste P from forming the artificial alveolar bone, and the paste inside the membrane 1. It is a method of forming an artificial alveolar bone by inserting and hardening (P).

That is, by covering the titanium membrane (1) in the thin portion of the alveolar bone, and fixing the membrane (1) by the screw (3) to form an internal space into which the paste (P) is to be inserted so that the paste does not flow out It is a way.

However, the GBR procedure method according to the prior art as described above has the following problems.

In order to form a space in which the paste P is to be inserted into the membrane 1, the membrane 1 must be fixed so as not to be recessed into the alveolar bone. However, when fixing the membrane using the existing screw (3), there is a problem that can not prevent the deformation of the membrane (1) by the external force applied from the outside.

In addition, when an implant is performed on a patient with alveolar bone loss due to periodontitis, the lower screw portion of the black implant is exposed to the gum as it is, so it does not look good and causes many complaints to the patient.

In order to solve such a problem, a procedure such as bone transplantation or bone expansion is required, but such a procedure may involve side effects and pain, and there is a problem in that the treatment period and treatment cost are increased.

The present invention is to solve such a conventional problem, it is an object of the present invention to provide an implant suitable for a patient with severe periodontitis with a large loss of alveolar bone.

According to a feature of the present invention for achieving the above object, the implant having an intermediate pier of the present invention is the upper pier to which artificial teeth are connected; Screws that are implanted in the alveolar bone; and preferably the upper pier and the intermediate pier connected to the screw.

It is preferred that the upper pier, the screw and the connecting member for connecting the intermediate pier integrally of the present invention is further included.

Preferably, the upper pier and the intermediate pier of the present invention are inserted into and connected to the first connection unit chamber formed in the intermediate pier.

It is preferable that the intermediate pier of the present invention and the screw are inserted into and connected to the second connection chamber formed in the screw.

The screw of the present invention is formed on the top of the screw, fine screw consisting of a double screw; Intermediate thread is formed on the middle of the screw; And preferably formed on the lower end of the screw, the lower screw line is formed to be narrower toward the tip.

The fine thread of the present invention preferably has a shorter thread width and spacing relative to the thread width and spacing of the intermediate thread and the lower thread.

The fine thread and the intermediate thread of the present invention is preferably surface-treated for bone fusion.

Preferably, the fine thread and the intermediate thread of the present invention are surface treated with sandblast large grit acid etch (SLA).

The upper pier and the middle pier of the present invention is preferably painted or plated for natural tooth color.

The upper pier and the intermediate pier of the present invention is preferably tin plated.

The intermediate pier of the present invention is preferably formed in a variety of vertical length.

According to the implant having an intermediate pier according to the present invention, the problem that can occur in patients with severe periodontitis in which alveolar bone is lost due to periodontitis can be minimized by the intermediate pier, due to the natural gum color of the intermediate pier There is an advantage that can improve patient satisfaction with the implant.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the implant having an intermediate pier according to the present invention will be described in more detail.

3 and 5 show a preferred embodiment of an implant with an intermediate bridge according to the present invention.

As shown, the implant of the present invention is provided with an upper pier 10 to which the artificial tooth (T) is connected. The upper pier 10 is to serve to support the artificial tooth (T), the body portion 11 for supporting the artificial tooth (T) and the support supported on the intermediate abutment 30 to be described below It may consist of (13).

The center of the cross section of the body portion 11 is recessed from the outside to the inside is formed with a seating groove 15 in communication with the outside. The seating groove 15 is formed with an insertion hole 17 into which the connecting member 20 for connecting the upper pier 10 to the intermediate pier 30 and the screw 40 integrally is inserted.

The lower portion of the body portion 11 is provided with a support 13 is supported by the intermediate pier 30, the lower portion of the support 13, the upper pier 10 to the intermediate pier 30 It is provided with a first connecting portion 19 for connecting with.

The first connecting portion 19 is composed of a hexagonal driver is seated in the first connecting portion chamber 31 formed on the upper pier 30. Since the first connector 19 is seated and fixed to the first connector chamber 31, the upper pier 10 is connected to the intermediate pier 30.

The outer surface of the upper pier 10 may be painted or plated to reproduce the tooth color as much as possible. Painting or plating similar to tooth color is preferably tin plating closest to the natural tooth color.

The connection member 20 inserted into the insertion hole 17 of the upper pier 10 may be formed in the shape of a rod having a thread line S formed at one end thereof. The connection member 20 may be composed of a head portion 21 seated and fixed to the insertion hole 17 and a fixing portion 23 fixed to the screw 40 through the intermediate pier 30. have.

The screw thread S formed on the fixing part 23 is screwed with the thread A formed inside the screw 40, so that the connection member 20 may be fixed to the screw 40.

Intermediate pier 30 connecting the upper pier 10 and the screw 40 is connected to the lower portion of the upper pier 10. The intermediate pier 30 serves to reinforce the bearing capacity of the implant when the alveolar bone density is low due to severe periodontitis, and exhibits an aesthetic effect through natural tooth color.

The characteristics of the anterior bone, which causes severe periodontitis, are very narrow in the width of the corneal region, sufficient in the apex region, and long in length. This anterior part is the most visible part of the face corresponding to the very aesthetically sensitive area, the black of the screw 40 is projected on the gums, causing a lot of complaints to the patients.

In order to solve this problem, a bone graft or ridge split technique is involved, which is accompanied by many problems such as side effects, patient pain, prolongation of treatment, and increase in treatment cost.

Therefore, the screw 40 having a black color is preferably placed in a deep alveolar bone having a good bone state. However, when the screw 40 is deeply implanted, the distance between the occlusal surface and the screw 40 becomes far and difficult to prosthetic. Teeth 30 are required.

In the upper center of the intermediate pier 30 is formed a connection chamber 31, the first connecting portion 19 of the upper pier 10 is seated. In addition, a through groove 33 penetrating from the connection chamber 31 to the lower end of the intermediate pier 30 is formed at the inner center of the intermediate pier 30. Since the connection member 20 penetrates through the through groove 33 and is fixed to the screw 40, the intermediate pier 30 may be connected to the screw 40.

The lower end of the intermediate pier 30 is provided with a second connecting portion 35 for connecting the intermediate pier 30 to the screw 40. The second connection part 35 is also formed in a hexagonal driver shape and is seated in the second connection part chamber 41 of the screw 40. Since the second connection part 35 is seated in the second connection part chamber 41 of the screw 40, the intermediate pier 30 is connected to the screw 40.

The outer surface of the intermediate pier 30 may be painted or plated to reproduce the tooth color as much as possible. Like the upper pier 10, the intermediate pier 30 is preferably subjected to tin plating closest to the natural tooth color.

The lower portion of the intermediate pier 30 is connected to the screw 40 is fixed in the alveolar bone. The top of the screw 40 is provided with a screw head portion 43 is formed with a second connection chamber 41 on which the second connection portion 35 of the intermediate pier 30 is seated.

In addition, a fixing groove 45 penetrating from the second connection chamber 41 to the stop portion of the screw 40 is formed at the inner center of the screw 40. The lower end of the fixing groove 45 is formed with a screw thread (A) to which the screw thread (S) of the connecting member 20 is screwed. Since the screw thread S of the connecting member 20 is screwed to the thread A of the screw 40, the upper pier 10, the middle pier 30 and the screw 40 may be integrally fixed. Can be.

A screw line having a general screw shape may be formed at a lower end of the screw head part 43 of the screw 40. However, in order to be more firmly fixed to the alveolar bone, a fine screw portion 51, an intermediate screw portion 53, and a lower screw portion 55 may be formed at the lower end of the screw head portion 43.

The fine screw portion 51 serves to prevent the alveolar bone melting in contact with the fine screw 40. At the upper end of the alveolar bone in contact with the screw 40, the alveolar bone is absorbed downward, so that the alveolar bone melts. Therefore, the alveolar bone may be prevented from melting by widening the contact area between the alveolar bone and the screw part 50 by the micro screw part 51 having the fine thread spacing and the width of the screw wire and having the double screw line having the overlapping thread. Can be.

An intermediate screw portion 53 is formed at the lower end of the fine screw portion 51 to be implanted and fixed in the alveolar bone. The intermediate screw portion 53 is a portion fixed to the alveolar bone in contact with the alveolar bone, and has a relatively wider thread spacing and a thread width than the thread spacing and the thread width of the fine screw portion 51.

The fine screw portion 51 and the intermediate screw portion 53 may be a surface treatment to promote bone fusion between the screw 40 and the alveolar bone. This surface treatment may be a surface treatment such as sandblast large grit acid etch (SLA), and SLA treatment refers to acid corrosion treatment after cutting the implant body by blowing a large grain of metal grain at a high pressure. In the case of the screw 40 subjected to such a surface treatment, the prosthesis may be installed after about 6 weeks because the bone cells are most suitable to stick to the screw 40.

A lower screw portion 55 is provided at the lower end of the intermediate screw portion 53 to dig into the alveolar bone and mechanically support the alveolar bone. The lower screw portion 55 is formed to be narrower toward the bottom, so as to not only directly dig the alveolar bone, but also to secure the screw 40 until the bone grows to support the screw 40. It plays a role.

Since the lower screw portion 55 is for securing the initial support force of the implant through the mechanical support force of the screw, it is preferable that the surface treatment for securing the support force of the screw 40 by bone fusion.

Hereinafter will be described in detail the operation of the implant with an intermediate pier according to the present invention having the configuration as described above.

The screw 40 is placed in the site to be implanted. The lower screw portion 55 of the screw 40 is dug into the alveolar bone and is fixed in the alveolar bone with mechanical support force, thereby obtaining an initial fixation force.

In addition, the intermediate screw portion 53 promotes bone adhesion with the alveolar bone by surface treatment, thereby obtaining a strong support force, and the fine screw portion 51 is formed of a double screw to prevent the alveolar bone from melting.

When the screw 40 is fixed to the alveolar bone, the intermediate pier 30 is connected to the screw 40. The intermediate pier 30 may be connected to the screw 40 by inserting the second connector 35 of the intermediate pier 30 into the second connection chamber 41 of the screw 40.

When the intermediate pier 30 is connected to the screw 40, the first connection 19 of the upper pier 10 is inserted into the first connection chamber 31 of the intermediate pier 30 to the The upper pier 10 is connected to the intermediate pier 30.

When the upper pier 10 is connected to the intermediate pier 30, the connecting member 20 is inserted into the insertion hole 17 of the upper pier 10, and the connecting member 20 is It penetrates through the upper pier 10, the intermediate pier 30 and the screw 40.

The screw line S of the connecting member 20 is fixed to the thread A formed in the screw 40 to fix the connecting member 20. When the upper pier 10, the intermediate pier 30 and the screw 40 is fixed by this method, an artificial tooth (T) can be installed on the upper pier 10.

In the scope of the basic technical spirit of the present invention, many modifications are possible to those skilled in the art, and the scope of the present invention should be interpreted based on the claims which will be described later. .

According to the implant having an intermediate pier according to the present invention as described in detail above has the following advantages.

In patients with severe periodontitis, in which the alveolar bone is largely lost, the intermediate brace increases the fixation force of the implant in place of the gum and blocks foreign substances or bacterial invasion.
