Description

Dental implant {Dental Implant}

The present invention relates to a dental implant, and more particularly, to an abutment that is inserted into a fixture implanted in alveolar bone as a lower portion and a crown is fixed as an upper portion, the outer peripheral surface of the lower portion The abutment can be installed on the fixture by directly pressing the outer circumferential surface of the abutment due to the fastening member having a screw portion formed on the screw portion and provided with a fastening portion corresponding to the screw portion. It relates to a dental implant for performing an implant operation.

In general, dental implants have a volume that can be sufficiently covered through additional surgery such as bone grafting or bone extension to the jawbone at the site where the tooth is missing or where the tooth is extracted. It is a dental treatment that restores the function of natural teeth by implanting a biocompatible implant body into the extended jawbone.

Tooth transplantation was performed in ancient times, and artificial teeth made of gold and ivory were used in the 16th and 17th centuries, and metal implants made of gold, silver, lead, iridium, iron, and cobalt alloys were introduced in the early 20th century. was developed

After the 1940s, subperiosteal implants and titanium blade implants were developed and popularized, but their lifespan was short and the success rate was low. Then, in 1982, in Toronto, Canada, Branemark of Sweden announced the osseointegration implant, which had been researched for 15 years, and the success rate exceeded 90%, and it became widely popular around the world.

Such an implant refers to a substitute for restoring human tissue when it is originally lost, but in dentistry, it refers to artificial tooth implantation.

In other words, implants can replace the root of a lost natural tooth by implanting an artificial tooth root made of titanium, which does not have a rejection reaction in the human body, in the alveolar bone from which the natural tooth has escaped, and then attaching it to the artificial tooth. It is a cutting-edge procedure that restores the original function of natural teeth by fixing the crown.

A dental implant is composed of a fixture to be placed in the alveolar bone, an abutment fastened to the fixture, and a crown in the shape of a real tooth mounted to the abutment.

Here, the fixture corresponding to the tooth root is also called an artificial tooth root, a implanted body or a fixed body in the art, an abutment is also called an abutment or an abutment, and a crown corresponding to the tooth is an artificial tooth, Also called crown or prosthesis.

In addition, as the prior art of dental implants having various types and treatment methods, the 'tooth implant system' of the Korean Intellectual Property Office Registration No. 10-0419738 and the 'healing' of the Korean Intellectual Property Office Registration No. 10-0677870 Abutment and dental implant having the same' and 'implant for flapless or mini flap surgery' of Korean Patent Office Registration No. 10-0879777 have been disclosed.

In other words, generally speaking, artificial teeth refer to teeth that are artificially made so that people without teeth can eat food. These artificial teeth are divided into dentures that can be inserted and removed from the gums and artificial teeth that are permanently fixed to the gums.

In order to permanently fix the artificial tooth to the alveolar bone of the gum, an implant is used, which penetrates the soft tissue of the gum and directly implanted into the alveolar bone, and the artificial tooth root is screwed into the upper inner side of the upper part. It consists of an abutment to which the artificial tooth is fixed.

Therefore, when fixing the artificial tooth to the patient, first, the artificial tooth root is penetrated into the soft tissue of the gum and firmly fixed to the alveolar bone with screws. Then, the abutment is firmly fixed with a screw on the upper part of the artificial tooth root fixed to the alveolar bone. And finally, the artificial tooth manufactured for the patient is fixed to the abutment connected to the artificial tooth root.

Then, the artificial tooth is maintained semi-permanently implanted by the implant consisting of the artificial root and abutment, so that it can play the role of a natural tooth.

Here, each patient who receives implants for artificial teeth has different characteristics such as the shape of the alveolar bone and the angle of the natural teeth. Therefore, when manufacturing the abutment of the implant, the shape of the patient's alveolar bone and the angle of the natural tooth are thoroughly inspected in advance through radiography and computed tomography.

This is because the artificial tooth is coupled to the upper portion of the abutment and the artificial tooth root is coupled to the lower portion of the abutment, so the angle between the alveolar bone and the artificial tooth is determined by the angle between the upper and lower portions of the support.

However, even if the angle between the upper and lower parts of the abutment is carefully inspected in advance as described above to meet the conditions such as the patient's alveolar bone shape and natural tooth angle, the artificial root of the artificial tooth is damaged due to other external factors during the operation. There was a problem that could not be corrected if it was not etched at a fixed position and angle.

That is, since the angle between the upper part and the lower part of the abutment is fixed, it is impossible to change it. Therefore, the only way was to re-manufacture the abutment to compensate for the misaligned angle of the artificial root.

In addition, since the angle between the upper and lower portions of the abutment is configured differently for each patient, mass production is not possible, so there is a problem that the production cost is high.

Because of these problems, the present inventor has proposed a 'dental implant capable of adjusting the angle of the abutment' of the Republic of Korea Patent Office Registration No. 10-1065924, as shown in FIG. 1 .

That is, in the patent technology, the angle adjusting means includes a circular ball 31 formed in a spherical shape on the upper portion of the connecting body 30 , a cutout 41 cut in the longitudinal direction on both sides of the rotating body 40 , and the rotating body. It is formed in an arc shape on the inner side of the lower part of the 40 and the cut-out part 41 is expanded and the ball groove part 42 into which the circular ball 31 is inserted, and one side of the rotating body 40 based on the cut-out part 41 and The bolt hole 43 and the screw hole 44 formed on the other side, respectively, are penetrated to one side of the rotating body 40 through the bolt hole 43 and are screwed into the screw hole 44 to reduce the cut-out 41 . It consists of a fixing bolt 50 for fixing the rotating body 40 so that the circular ball 31 is strongly pressed from the ball groove portion 42 .

However, in the patent technology, the angle adjusting means is screwed to the bolt hole 43 and the screw hole 44 respectively formed on one side and the other side of the rotating body 40 and strongly compressed with the fixing bolt 50, but the circular ball 31 There is a problem in that the circular ball 31 cannot be sufficiently gripped over time because it cannot be squeezed directly from both sides and is compressed indirectly.

The present invention has been devised to solve the above problems, with a screw portion on the outer periphery of the lower part for an abutment that is inserted into a fixture implanted in the alveolar bone in the lower part and the crown is fixed in the upper part. Since the abutment can be installed in the fixture by directly pressing the outer periphery of the abutment due to the fastening member formed and provided with the fastening part corresponding to the screw part, the bonding force is improved compared to the prior art, so that the implant operation is more stable and precise. An object of the present invention is to provide a dental implant that can do

In addition, the horizontal cross section of the insertion portion 132 and the insertion groove 111 is formed in an elliptical or polygonal shape to prevent the insertion portion 132 from being rotated and moved within the insertion groove 111 .

Then, the components of the dental implant 100 according to an embodiment of the present invention will be described in detail as follows.

The dental implant 100 proposed by the present invention is to operate the crown (T), which is an artificial tooth functioning as a natural tooth, on the alveolar bone (B) inside the gum (G).

Therefore, the dental implant 100 proposed in the present invention is inserted into the upper inner side of the fixture 110 and the fixture 110 to be implanted in the alveolar bone (B) and the crown (crown, T) is fixed to the upper part. It is composed of an abutment (abutment, 120).

In particular, the dental implant 100 proposed in the present invention has a stronger fastening force than the conventional one, and the angle between the fixture 110 and the crown T can be freely adjusted through the abutment 120 , but more powerful than Its great feature is that it has a structure that can be precisely fixed.

As shown in FIGS. 2 to 4, the dental implant 100 according to an embodiment of the present invention penetrates the soft tissue of the gum G and is screwed into the alveolar bone B. Fixture 110 and an abutment 120 that is inserted and coupled through the inner side of the upper portion of the fixture 110, and the crown T is fixed thereon.

In addition, the abutment 120 includes a connection member 130 , a rotation member 140 , and a tightening member 150 .

Accordingly, the abutment 120 is a connecting member 130 fixed to the fixture 110, a rotating member 140 to which the crown T is fixed, and a tightening member 150 for pressing the lower portion of the rotating member 140. Separately configured, the rotation member 140 can be freely adjusted and fixed at an angle on the connection member 130 using the tightening member 150 .

In addition, the abutment 120 includes a spherical ball 131 formed in a spherical shape on the upper portion of the connecting member 130 , a cutout 141 cut in the longitudinal direction on both sides of the rotating member 140 , respectively, and a rotating member ( A ball groove portion 142 formed in an arc shape on the lower inner side of the lower inner portion of the rotary member 140 and into which the spherical ball 131 is inserted while the cutout 141 is expanded, and a screw portion 143 formed along the outer periphery on the lower outer side of the rotating member 140 . ) and a fastening part 151 is formed in correspondence with the screw part 143 on the inside of the tightening member 150 . Here, the screw part 143 may correspond to a male screw, and the fastening part 151 may correspond to a female screw.

That is, the abutment 120 proposed in the present invention has a structure such as a ball joint, and is connected through the cut-out 141 and the tightening member 150 that directly presses the cut-out 141 . It has a configuration capable of fixing the angle formed by the member 130 and the rotating member 140 .

In particular, as shown in FIG. 2 , at least two or more (2, 3, 4, 5, 6, etc.) of the cutout 141 are formed so that the spherical ball 131 is easily inserted into the ball groove 142 as shown in FIG. Widen as much as possible over a hemisphere so that it can be expanded

Even if it is fixed at an angle as shown in (b), the abutment 120 can be created vertically so that the teeth can be evenly arranged.

Therefore, when the operator wants to operate the implant 100 on the patient, the angle between the connecting member 130 and the rotating member 140 through the abutment 120 proposed in the present invention is determined by the patient's alveolar bone shape and natural tooth angle. Since it can be arbitrarily adjusted and fixed to suit the characteristics of the patient, there is no need to manufacture the abutment 120 having a different angle for each patient.

Accordingly, it is possible to not only make the operation of the implant 100 very conveniently, but also reduce the pain of the patient due to the operation of the implant 100 . And since the abutment 120 proposed in the present invention can be mass-produced for each component, productivity of the implant 100 can be improved.

Here, the operation of the present invention through the procedure of the implant 100 will be described in more detail as follows.

First, the fixture 110 is fixed to the alveolar bone (B) of the gum (G). At this time, since a screw is formed on the outer circumferential surface of the fixture 110, it may be fixed to the alveolar bone (B) with a screw type.

Then, as shown in FIG. 3, the connecting member 130 and the rotating member 140 are coupled through the upper inner side of the fixture 110, and the connecting member 130 is inserted and fixed to the fixture 110. .

At this time, the connecting member 130 has an insertion portion 132 tapered toward the bottom, and an insertion groove 111 that is tapered toward the bottom of the upper inner side of the fixture 110 corresponding thereto. Adopt a fitting method in which the 132 is pressed into the insertion groove 111 .

This conventionally has problems such as when the fixture 110 and the connecting member 130 are fastened with a screw type, it is inconvenient and the angle is not accurately adjusted because it takes a lot of time and trouble to attach and detach the equipment separately.

Therefore, as shown in FIG. 3, since the connecting member 130 is inserted into the fixture 110 by pressing in the 'A' direction, it can be easily mounted as well as naturally compressed when a person chews food or closes the mouth. This is because it is possible to mount more efficiently than the conventional screw type fastening.

In addition, the horizontal cross section of the insertion portion 132 of the connecting member 130 and the insertion groove 111 of the fixture 110 is formed in an elliptical or polygonal shape so that the insertion portion 132 is rotated while being engaged in the insertion groove 111 or Avoid moving left and right.

Next, the rotating member 140 is in the shape of a truncated cone, the cut-out 141 is cut downward and one side is open, the lower inner side is formed in an arc shape, the cut-out 141 is expanded, and the ball into which the sphere ball 131 is inserted. A screw portion 143 formed along the outer periphery of the groove portion 142 and the lower outer side is provided.

After the connecting member 130 is inserted and pressed into the fixture 110 together with the rotating member 140 as described above and fixed, the angle of the rotating member 140 is adjusted.

That is, by adjusting the angle of the rotating member 140 on which the crown (T) is installed, it conforms to the characteristics of the patient's alveolar bone shape and natural tooth angle.

In addition, the fastening member 150 fastens the connecting member 130 and the rotating member 140 , but a fastening part 151 is formed on the inside corresponding to the screw part 143 .

Accordingly, the sphere ball 131 is inserted and seated into the ball groove 142 as it expands due to the cutout 141 spaced apart by a predetermined distance, and the rotating member 140 is inserted from the upper part to the lower part by inserting the tightening member 150 to the screw part ( The fastening part 151 is screwed to 143).

Next, the screw portion 143 and the fastening portion 151 are screwed together to rotate the tightening member 150 on the lower outer side of the rotating member 140, so that the gap between the cutout portions 141 is reduced while the sphere ball 131 is The ball groove portion 142 directly receives a strong pressure to be fixed.

Then, as the cutout 141 of the rotating member 140 is reduced, the ball groove 142 of the rotating member 140 strongly presses the spherical ball 131 of the connecting member 130, and this ball groove 142 The rotating member 140 is fixed at the adjusted angle by the strong pressing force of the .

Then, the crown (T) is placed on the upper portion of the rotating member 140 and fixed. Then, the operation of the implant 100 is all completed.

Meanwhile, the tightening member 150 may be a hexagonal nut having a fastening part 151 formed therein.

Since this uses a generalized hexagon nut, it is possible to reduce the manufacturing cost, it is easy to purchase, and there are several economic advantages such as reducing the manufacturing cost.

As described above, the dental implant 100 according to an embodiment of the present invention is a fastening member 150 using the connecting member 130 and the rotating member 140 of the abutment 120 to be strong to suit the characteristics of the patient. The angle between the fixture 110 to which the connecting member 130 is fixed and the crown T installed on the rotating member 140 can be set very conveniently.

When the connection member 130 is separated from the fixture 110 in the future, using the lever principle, the upper surface of the fixture 110 is supported while wrapping the lower part of the sphere ball 131 in the form of a fork of the easy window, and the bar extends from the fork of the easy window. It can be implemented in various ways, such as pressing the end of the bar (bar) so that the insertion part 132 can be easily removed from the insertion groove 111.

Therefore, the dental implant according to an embodiment of the present invention can be expected to have the following effects.

The angle between the fixture and the crown can be freely adjusted to suit the patient, and since the fastening member with the inner fastening part directly presses the screw, it can have a stronger fastening force than the prior art, and thus can be maintained more stably.

In addition, since the implant can be maintained for a longer period than before, there is an advantage that can reduce the economic burden on the patient.

In addition, while having a simpler structure than the prior art, more effective and mass production of each part is possible, so there is an advantage that a ripple effect can be expected in a dental procedure.

In this way, the present inventors have a threaded portion formed on the outer periphery of the lower portion for an abutment that is inserted into a fixture implanted in alveolar bone as a lower portion and a crown is fixed as an upper portion, and the screw portion Since the abutment can be installed on the fixture by directly pressing the outer periphery of the abutment due to the fastening member provided with the fastening part corresponding to We were able to complete dental implants for
