Description

[0001] DENTAL IMPLANT SYSTEM [0002]

Implant

The present invention relates to a dental implant, and more particularly to a dental implant having a proximal plate-like protrusion. The occlusal force can be divided into normal force and horizontal force. The normal force on the implant is the compressive force at the bottom and the shear force at the side. The horizontal force is a tipping force on the implant, which means that both ends are pressed in different directions.

Since the horizontal force toward the proximal side is jointly supported by the adjacent teeth (or implants), such lateral forces have less effect on the alveolar bone. Dental implants are fixed to the bone and resist the occlusal force.

Thus, ensuring that the implant has sufficient alveolar bone fixation for occlusal forces and that the alveolar bone is not destroyed is the primary and most important consideration in dental implant design.

Since the advent of titanium dental implants, many dental implants have retained the shape of unmodified natural roots. However, in fact, the supporting mechanism of the natural tooth and the supporting mechanism of the implant are not the same. Natural teeth are caught in the bone by ligaments, and the implant is fixed to the bone. It is not easy to imitate the shape of the root.

Conventional dental implants include a central portion and a plurality of fins. The shape of the central portion is a tapered cylindrical portion. The taper at the center of the dental implant reduces the resistance of the vertical and horizontal surfaces. Clinically, the deeper portion of the alveolar bone always has a large space of the implant. Also, the disadvantages of many current implants are thread or pin. The thread or pin is basically a horizontal protrusion from the center. The pins (horizontal protrusions) are less prone to horizontal forces than vertical forces,

Fixed. This explains why the success rate of the implants in the maxilla is always lower than the success rate in the mandible. Implants in the maxillae receive more lateral force than implants in the mandible.

U.S. Patent No. 4,738,623, which discloses a dental implant system considered by many dentists as one of the best implant systems, also has the above-described problems. Like other implants, insertion into the bone is the most vulnerable. Conventional dental implants seriously address these problems. According to the instructions, conventional dental implants are implanted 1-2 mm below the alveolar crest. Next, a portion of the bone is removed, and the abutment and crown are connected to a conventional dental implant. However, as clinically observed, the bones are eventually reprocessed into the shoulders of conventional dental implants. Although the material of the implant and the abutment post is the same, the bridge column is not osseointegrated. Micro-rotation may occur in the bridge column. Pillars that are not ossified in bone become pathways of harmful bacteria. In some cases, the deterioration of the bone continues and the exposure of the implant becomes inevitable. This exposure often occurs in terms of supporting horizontal forces.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a dental implant capable of more accurately coping with lateral forces from the occlusion by designing a vertical proximal plate-like projection and a clearance.

And solves the problems of the problems according to the concrete contents for carrying out the following invention.

According to the dental implant of the present invention, it is possible to more accurately and efficiently cope with the horizontal force from the occlusion by designing the vertical proximal plate-like projection and the clearance.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, a dental implant of the present invention includes a central portion, at least one proximal plate-like projection, and at least one fin. The central portion has a first portion, a second portion, a horizontal portion, and a vertical portion. The proximal plate-shaped protrusion protrudes from the first portion of the central portion along the horizontal portion, and extends along the vertical portion. The pin protrudes from the second portion of the central portion along the horizontal portion.

The dental implants of the present invention pay more attention to the horizontal forces that are generally ignored by other systems. By designing the proximal plate-like protrusions and clearances on the ball side and tongue side, the dental implant can more accurately cope with the horizontal force from the occlusion.

The proximal plate-shaped protrusions fix the bone against the horizontal force and deviate from most of the normal force. The plate-shaped protrusion protrudes from the cylindrical portion in a distal or mesial direction. The horizontal portion of the proximal plate-

There is no proximal plate-shaped protrusion on the ball side and tongue side. Since the ball and dorsal bony plates are always thin and vulnerable to dental implants, the corrugated plates should not support too much force.

The dental implant further includes a neck disposed at a first portion of the central portion. By extending with the neck, the clearance and neck provide more space for the corrugation and deliver less force to the corrugation. The implant provides a space in which the thin plate is not disturbed by any one of the protrusions and improves cosmetic appearance because the possibility of exposure of the neck is reduced. Implants effectively cope with the horizontal force by the plate-shaped protrusions surrounded by a wide bone structure.

The dental implant of the present invention is generally cylindrical and is an unthreaded implant for later joining the piercing teeth for artificial prosthesis.

The dental implant includes a central portion, at least one upper proximal projection, at least one fin, and at least one lower proximal projection. The center portion

A second portion, a third portion, a horizontal portion, and a vertical portion. In this embodiment, the central portion is cylindrical and is not tapered.

The central portion further includes a neck disposed in the first portion. The height of the neck is approximately 0.5 to 3.0 mm. The neck has an edge that is partially rounded and the edge faces inwardly with respect to the longitudinal axis of the dental implant. Preferably, the neck is formed as narrow as possible, if mechanically permissible. The neck with such a design has a rim and the neck of the neck is narrow. The rim facing the ball side is trimmed to have the curvature of the gum on the ball side. It is preferable that the trimming rim is formed downward from the proximal side to the ball side and is concave. The trimming rim prevents the surgeon from implanting the bone depth implant without worrying about exposing the dental implant to the ball side. It is also preferred that the trimming rim corresponds to an asymmetrically resorbed ridge. The depth of the trimming rim is 0.5 to 2 mm.

Next, the upper proximal plate-like projection and the ball side and the lingual side clearance will be described. The upper proximal plate-shaped protrusion protrudes from the first portion of the central portion along the horizontal portion, and extends along the vertical portion. In this embodiment, a plurality of upper proximal plate-like projections are provided in the first portion of the central portion. Preferably the upper proximal projection is cut wide at the upper edge forming the cut upper edge.

The top plate-shaped protrusion is formed with a tangent of approximately 90 degrees from the center to the center, or a protruding angle which is easily manufactured or can fix a large number of bones to the horizontal force. Preferably, the top plate-shaped protrusion does not extend beyond the tangent of the ball-side or tongue-side region.

The plate-shaped protrusion is advantageous for fixing the bone against horizontal force and deviates from normal force. This design can prevent overloading. The proximal plate-like projection is parallel to an adjacent proximal plate-like projection adjacent to the proximal plate-like projection.

The upper proximal plate-like protrusion is disposed on the proximal side of the first portion, and the first portion has a ball side clearance and a tongue side clearance without the upper proximal plate-like protrusion. Ball side and tongue side

The loudness is arranged on the ball side and the tongue side of the first part, respectively. That is, the upper proximal plate-like projection is not formed on the ball side and the tongue side in the horizontal portion of the upper plate-like projection. The clearance is a protrusion. Since the ball and tongue-side corrugations are always thin and vulnerable to dental implants, it is advisable that the corrugated plates do not support too much force. By extending with the neck, the clearance and neck provide more space for the corrugation and deliver less force to the corrugation.

The dental implant of the present invention effectively copes with the horizontal force by the proximal plate-shaped protrusions surrounded by a large bone tissue. Thus, the likelihood of bone deterioration is reduced. The length of the first portion having the upper proximal plate-like projection is about 1/4 to 2/5 of the total length of the center portion. Since the horizontal force is least influenced by the central part of the center

The plate-like projection is not provided in the central portion of the central portion.

The proximal plate-shaped projection includes at least one positioning proximal plate-shaped projection, and the positioning proximal plate-shaped projection extends outside the outer diameter of the pin. Thus, the width of the positioning proximal plate-like projection is larger than the width of the proximal plate-like projection. In this embodiment, two locating proximal projections are disposed on the proximal side for determining the position of the dental implant. In addition, the right direction after treatment

Thereby making it easier to maintain the dental implant in the bone.

Further, the proximal plate-like projection includes at least one pulling proximal plate-like projection. In this embodiment, the positioning proximal plate-like projection is a pulling proximal plate-like projection. The length of the pulling proximal plate-like projection is longer than the length of the proximal plate-like projection and the pulling proximal plate-shaped projection is extended to the neck. The pulling proximal plate-like protrusions are provided with a pulling hole for receiving a pulling device for pulling the dental implant

I have. In addition, the pulling proximal plate-like projection has a pulling groove for receiving a pulling device for pulling the dental implant.

The proximal plate-shaped projection includes at least one normal proximal plate-shaped projection. In this embodiment,

The length of the reference proximal plate-like projection is shorter than the length of the pulling proximal plate-like projection, and the width of the reference proximal plate-like projection is smaller than the width of the positioning proximal plate-like projection. That is, the width of the reference proximal plate-like projection is the same as the outer diameter of the pin.

The proximal plate-like projection includes at least one small proximal plate-like projection. In this embodiment, the length of the small proximal plate-like projection is shorter than the length of the reference proximal plate-like projection, and the width of the small proximal plate-like projection is smaller than the width of the reference proximal plate-like projection.

Thus, the length of the proximal plate-like projection gradually decreases from the pulling proximal plate-like projection to the small proximal plate-like projection, and the width of the proximal plate-like projection gradually decreases from the positioning proximal plate-like projection to the small proximal plate- .

The upper proximal plate-like projection has an angle corresponding to the longitudinal axis of the dental implant. In the first embodiment, the angle of the plate-like projection is 0 degrees. However, the angle of the proximal plate-like projection is between 0 and 45 degrees. That is, the proximal plate-shaped protrusion has an inclination angle between 0 and 45 degrees.

On the other hand, next to the plate-like projection, the pin protrudes from the second portion of the central portion along the horizontal portion. In this embodiment, a plurality of pins are annularly provided on the outer surface of the second portion of the central portion. The pin is not tapered. The length of the second portion with the pin is about 1/5 to 1/2 of the length of the center portion.

And the lower proximal plate-like projection is disposed in a third portion of the central portion. The length of the third portion having the lower proximal plate-like projection is about 1/4 to 2/5 of the total length of the center portion. The projecting angle of the lower proximal plate-like projection is proposed to be orthogonal to the tangent of the central portion. The lower proximal plate-

It has a negative edge. Near the bottom of the central portion, the edge of the plate-shaped projection is cut to correspond to the bottom of the socket-shaped bonysocket, i.e., to correspond to the shape of the drill.

The central portion further includes a bottom surface and a well. The bottom surface is flat. The valley is connected to the bridge teeth and has an opening at the top of the central part.

The dental implant includes a central portion, at least one proximal plate-shaped projection, and at least one pin. The central portion has a first portion, a second portion, a horizontal portion, and a vertical portion. The central portion further includes a neck disposed in the first portion. The neck portion of the second embodiment is similar to the neck portion of the first embodiment. However, the neck is shorter. The neck portion includes a rim. The rim is flat or less trimmed. The length of the neck is between 0.5 and 2 mm and the depth of the trimming rim is suggested to be 0.5 to 2 mm.

The proximal plate-shaped protrusion protrudes from the first portion of the central portion along the horizontal portion and extends along the vertical portion. The clearance between the proximal plate-shaped protrusion on the ball side and the tongue side is similar to that described in the first embodiment. But the ratio is different. The length of the first portion having the proximal plate-like projection is about 1/6 to 2/5 of the total length of the center portion. The positioning proximal plate-like projection and the pulling-proximal plate-

Which is similar to that described above in the first embodiment. The pin projects from the second portion of the central portion along the horizontal portion. The central portion further includes a bottom surface and a bottom. The pin is not reduced in diameter but extends to the bottom. The bottom surface is concave. At the bottom, the bone receives a lot of compressive force. The concave bottom surface distributes the force. This is a big job

It is especially important for short dental implants with a diameter of less than 1 mm. If a portion is a cross shape, a specially designed drill is required to form the bottom of the socket bone.
