Description

Implant that surgical operation is easy}

The present invention relates to an easy implant connection column, and more particularly, to an implant connection column that is easily fixed to an artificial tooth implanted in an alveolar bone to bind an artificial tooth.

Implant is a technique for placing artificial teeth to replace lost teeth. In the case of commonly used prosthetics or dentures, the surrounding teeth and bones are damaged over time, but the implants do not damage the surrounding dental tissues. Patients who have lost their teeth are preferred because of the same function and shape as the teeth and no decay.

For example, the implant is implanted in the alveolar artificial tooth, which can replace the tooth root of the previously lost tooth, and the artificial tooth is bonded together with the connecting pillar on the artificial root. The implanted portion to be screwed together, and the pillar portion for fixing the artificial tooth on the upper end is formed integrally with a metal material.

However, in the related art, the connecting pillar is for placing artificial teeth in place of artificial teeth that are lost in the natural teeth, but many problems have been raised as follows.

First, the posts should be calibrated according to the position of the artificial teeth after implantation into the artificial tooth, but the posts should be calibrated as the joints and the posts are integrally made of hard metal (eg titanium). It takes a considerable time to cut, and because the connecting column is processed in the alveolar bone of the patient is not only a grievance of the patient.

Second, pressure and vibration applied while machining the pillar of the connecting column using a cutting tool (for example, a grinder) are transmitted to the artificial root, which lowers the fixing force of the insertion part, causing the flow to occur or the weak part of the alveolar bone is broken, thereby It causes a problem that needs to be repeated. In particular, there is a greater disadvantage in the case of an implant loading that allows food manipulation from the date of implantation of the artificial tooth by making a connecting artificial pole and making a temporary artificial tooth on the day of implantation of the artificial tooth root.

Third, if the column part breaks or the processing defect occurs during the use of artificial teeth after correcting the column and implanting procedure, the connection column must be replaced as a whole, resulting in additional cost burden due to the replacement of the expensive connection column. .

Fourth, the connecting column should be managed to prevent the upper and lower teeth from colliding for a certain period of time until the gums are recovered after the procedure. However, most of the pillars are initially made long to temporarily form the auxiliary teeth. A collision occurred, and accordingly, there was a problem in that the pillars had to separately prepare a short connecting column or cut the pillars to the required length.

Fifth, as the connecting column is made of the same metal material as the artificial tooth (for example, titanium), due to the same strength, the screw joint part is loosened during use, resulting in the end of the play.

In order to achieve the above object, the present invention is manufactured by dividing the implantation unit 120 and the pillar unit 130 of the connection column 100, and the implantation unit 120 is an internal thread portion A1 of the artificial tooth root A. The first male screw portion 124 is formed at the center of the upper portion while the first male screw portion 122 is formed at the lower portion thereof so that the first male screw portion 122 is formed, and the pillar portion 130 is the first female screw portion 124 of the insertion portion 120. The second male screw portion 132 is formed at the lower portion to be coupled to the lower portion, and the support portion 134 is provided to protrude so that the artificial tooth is fixed at the upper portion thereof.

At this time, the pillar portion 130 is characterized in that it is made of a synthetic resin material different from the implantation portion 120.

In addition, the inclined portions 140 and 140 ′ which are conically engaged with the first female and male screw portions 124 and 132 of the placing portion 120 and the pillar portion 130 are provided. .

In addition, the groove 126 for fastening a tool such as a wrench is formed in the center of the insertion portion 120 is characterized in that it is formed.

In addition, each surface 136 is formed on the outer circumferential surface of the support part 134 of the pillar part 130.

According to the above configuration and operation, the present invention is divided into the insertion part and the pillar part of the connection pillar is made of a material of a lower hardness than the insertion part, so that the loosening of the screw coupling portion after the procedure is prevented, and the low hardness of the pillar part Due to the ease of processing, even if the connection column is placed crookedly, there is an effect that the correction is made easily. In other words, the cutting tool (eg, grinder) is used to reduce the pressure and vibration transmitted to the artificial root during machining of the pillar of the connecting column to prevent the fixing force of the artificial root and the implantation portion from deteriorating. Loss of initial fixation of the root can also be prevented. In particular, it is more advantageous during the operation (immediate loading) to enable food manipulation from the day when the artificial tooth is placed by fastening the connecting pillar on the day when the artificial tooth is placed.

In addition, even if the column part is broken or a processing defect occurs during the use of artificial teeth after the column correction work and the implant procedure, partial replacement of the column part is possible, thereby greatly reducing the treatment cost and maintaining the effect of easy maintenance.

In addition, if you close the upper part by fastening only the insertion part of the connecting column, it will replace the role of auxiliary artificial teeth until the gum is recovered. There is an effect that the troublesome trouble of cutting the column part is solved.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to an easy-to-install implant connecting column, wherein the easy-to-operate implant connecting column is placed with the insertion unit 120 so as to facilitate the operation of the artificial tooth in a set position corresponding to the implantation position and natural teeth of the artificial tooth. The pillar portion 130 is divided into different materials.

The connection column 100 is manufactured by dividing the insertion portion 120 provided at the bottom and the pillar portion 130 protruding upward to fix the artificial tooth (T) to be implanted by screw coupling to the artificial tooth (A), respectively. It is provided to be connected by screwing.

At this time, the insertion portion 120 is formed with a first male screw portion 122 at the lower portion to be fastened to the female screw portion A1 of the artificial tooth A, and a first female screw portion 124 is formed at the upper center thereof. The implantation part 120 is formed in a conical structure in which the diameter becomes narrower toward the bottom so that the fastening force is tightly maintained as well as the flow and loosening after the fastening when the screw is coupled through the first male thread part 122, which will be described later in the upper center. A first female threaded portion 124 is formed to screw the second male threaded portion 132 of the pillar portion 130. The first female threaded portion 124 is preferably formed at the same pitch as the second male threaded portion 132, and is preferably formed of a triangular or trapezoidal screw so that the fastening force is accurately transmitted and not easily loosened.

In addition, an angle groove 126 for fastening a tool such as a wrench is formed at the center of the placement portion 120. That is, the angular groove 126 is formed with 4 to 8 angular grooves on the bottom of the center portion in which the first female threaded portion 124 is formed, as shown in FIG. By inserting the tool is rotated as well as fastening the insertion portion 120 is fastened, there is an advantage that the separation operation is also made easier if necessary.

In addition, the pillar portion 130 has a second male screw portion 132 formed at a lower portion thereof so as to be engaged with the first female screw portion 124 of the implantation portion 120, and a support portion for fixing the artificial tooth T at the upper portion thereof. 134 is provided to protrude. The pillar portion 130 is used as a means for fixing the artificial tooth T by protruding the pillar portion 130 while being coupled to the artificial tooth root A through the first male screw portion 132.

Then, the pillar portion 130 is made of a synthetic resin material of a different material from the implantation portion 120, and the artificial tooth (T) is cut into a predetermined shape to be treated in place. That is, when the artificial root A is inclined to one side on the alveolar bone, the connecting pillar 100 is also fastened in an inclined state, so that the artificial tooth T may be installed at a predetermined position in order to perform the artificial tooth T at a predetermined position. The 130 is cut with a tool such as a grinder, wherein the pillar portion 130 is made of a synthetic resin material having a different material from the implantation portion 120 (eg, the implantation portion is formed of a metal material such as titanium). It is excellent in shortening the procedure time, and also greatly reduces the processing pressure and vibration applied when machining the column part 130, and further prevents additional procedure defects such as lowering of binding force and flow of the artificial tooth A. have.

In addition, each surface 136 is formed on the outer circumferential surface of the support portion 134 of the pillar portion 130. Each surface 136 is a plane processing in the longitudinal direction on the outer circumferential surface of the support 134, as shown in Figure 4, a pair is formed at a position corresponding to each other in a pair or the support 134 is formed in the form of a four-octagonal rod. Accordingly, when the pillar 130 is fastened on the insertion part 120, when a tool such as a spanner is rotated in a state where the tool is inserted into each surface, damage to the pillar may be prevented, and thus, the pillar may be tightened or separated with a strong rotational force. On the other hand, the pillar portion 130 preferably forms a protrusion formed with a binding groove on the upper end of the support portion 134 to facilitate fastening / disassembly using a tool as shown in FIGS. 2 and 5b.

In addition, the inclined portions 140 and 140 ′ which are conically engaged with the first female and male threaded portions 124 and 132 of the implantation portion 120 and the pillar portion 130 are provided. The inclined portion 140 is formed in a conical structure, the diameter of which narrows toward the inside on the entry portion of the first female screw portion 124, as shown in the enlarged view of FIG. Another conical inclined portion 140 'is formed. Accordingly, when the second male threaded portion 132 of the pillar portion 130 is screwed onto the first female threaded portion 124 of the insertion portion 120, the inclined portions 140 and 140 'are engaged with each other and the first female When tightening the male screw parts 124 and 132, a repulsion force is generated in the opposite direction to the traveling direction, thereby preventing loosening after tightening.

In the procedure, first, the tooth is lost and the artificial tooth (A) is implanted on the alveolar bone where the artificial tooth (T) is to be treated, and then the insertion part 120 of the connecting column 100 is placed on the artificial tooth (A). Fasten to first, and leave the top closed with a finishing material such as artificial bone, when the gum is recovered, remove the finishing material and fasten the pillar portion 130. At this time, since the pillar portion 130 is inclined about (α) angle as shown in FIG. 3 according to the placement position of the artificial root A, reference numeral C is used by using a tool such as a grinder. When the supporting portion 134 is cut and the artificial tooth T is fixed in place, the implant procedure is completed.
