Description

Implant Fixtures {Implant fixture}

The present invention relates to an implant fixture.

In detail, the present invention performs the tooth root function of the anterior teeth when performing an implant procedure for a small anterior tooth or a weak tooth (hereinafter, commonly referred to as an anterior tooth), by minimizing its size in an integrally formed abutment The present invention relates to an implant fixture for minimizing the discomfort of a patient before mounting an artificial tooth.

In the case of missing teeth, a bridge procedure was performed in which a denture was inserted or a missing part was covered with a metal by using a surrounding tooth as a pillar. However, such a procedure has a number of problems, such as a false teeth or bridges artificial teeth chewing food and adversely affects the surrounding teeth. As a result, an implant procedure has emerged as a procedure of advanced dental care. This implant procedure is to form an artificial tooth root in the alveolar bone, by using an artificial tooth made similar to the actual tooth by using it to obtain the effect of the patient using the actual tooth.

The implant procedure is used to form a groove using a tool such as a drill to implant a fixture in the alveolar bone missing teeth, and performs a tapping to fix the fixture firmly inside the groove. Thereafter, the fixture is embedded in the groove, and then the abutment is attached to the fixture, and the artificial tooth is coupled to the abutment to complete the implant procedure.

Fixtures and abutments in the implant procedure as described above are manufactured and combined separately according to the treatment method, the fixture and abutment is formed integrally presented.

As described above, in the case of an anterior tooth with a small size, since the procedure is cumbersome when the fixture and the abutment are manufactured separately, the procedure is easy to use mainly because the fixture and the abutment are formed integrally. It also minimizes the stressors that are stressed.

As described above, the fixture in which the abutment is integrated remains uncoupled with the artificial tooth for a period of time during which the patient's gums are healed so that the fixture is completely fixed in the alveolar bone after implantation of the fixture.

At this time, the abutment is formed to have a size substantially similar to the size of the teeth in order to have a firm fixing force after the artificial teeth are coupled, so that the patient ingests food or the like for the above-described period (the period of the gums healing). When exposing the metal abutment becomes an uncomfortable factor.

The present invention has been invented to solve the above problems.

Therefore, the present invention, the abutment is kept to a minimum size when the gum is held after a fixed period of time to fix the fixture, so that the patient can have the desired size when combining the artificial teeth discomfort The aim is to provide an implant fixture that minimizes the number of implants.

Another object of the present invention is to provide an implant fixture for performing a buffer function against external force applied to an artificial tooth after the procedure.

In order to achieve the above object, the present invention has the following configuration.

According to the present invention, in the implant fixture in which the abutment is integrally formed, the abutment is formed at least smaller than the size for the artificial tooth to be coupled, and the size for joining the artificial tooth after embedding the fixture. The size correction member is coupled to the outer surface of the abutment to be maintained as it is configured.

At this time, a coupling groove recessed inward is formed around the point where the abutment fixture is coupled, and a coupling protrusion for corresponding coupling with the coupling groove is formed on the inner circumferential surface of the size correction member corresponding to the abutment fixture.

In addition, a buffer member is inserted between the abutment and the size correction member to mitigate the impact applied to the artificial tooth.

In addition, a fixing protrusion protruding toward the abutment side is formed on the inner circumferential surface of the size correction member, and a fixing groove is formed on the abutment opposite to the fixing protrusion.

As described above, the present invention, after implanting the fixture, the abutment is kept to a minimum size, and the artificial tooth can have the desired size when combining the artificial teeth to minimize the inconvenience of the patient at the same time There is an effect that allows the teeth to maintain the desired fixing force.

In addition, the present invention by adding a configuration to perform a buffer function against the external force applied to the artificial tooth after combining the artificial tooth can obtain an excellent procedure result and the effect of improving the patient satisfaction.

Embodiments of the present invention as described above will be described in detail with reference to the accompanying drawings.

Referring to the drawings, the implant fixture according to the present invention comprises a fixture 10 having a thread 11 formed on an outer surface thereof, and an abutment 20 integrally formed on an upper portion of the fixture 10.

At this time, the abutment 20 is formed to a size smaller than at least the size for the artificial tooth (T) is coupled. The meaning of the size smaller than the size for the artificial tooth (T) is coupled is about 1/2 of the size relative to the volume of the artificial tooth (T).

For reference, when the artificial tooth (T) is coupled to the abutment 20 having a size of about 1/2, since the fixing force of the artificial tooth (T) is weak, after the implant procedure, the artificial tooth (T) by a slight external force Is easily released from the abutment 20 as is well known.

Therefore, the abutment 20 smaller than the desired size (size to be combined with artificial teeth) as described above minimizes the discomfort that the patient receives during the period in which the patient heals the gums after the fixture 10 is fed. It is to have a configuration for, to couple the artificial teeth (T) is to combine the size correction member 40 on the outer surface of the abutment 20 to maintain the desired size.

At this time, a means for increasing the mutual coupling force is formed between the abutment 20 and the size correction member 40. This means is a coupling groove 21 formed in the inner periphery around the point of engagement with the fixture 10 of the abutment 20 and the coupling formed to protrude on the inner circumferential surface of the size correction member 40 corresponding thereto It is made of a projection (41).

In addition, when the size correction member 40 is formed of a metal material, between the abutment 20 and the size correction member 40, the buffer member 50 for mitigating the impact applied to the artificial tooth (T) ) Is fitted.

In this case, the buffer member 50 may have various embodiments such as latex, soft synthetic resin, rubber, and the like.

Referring to the drawings, the implant fixture of the other embodiment is configured such that the function of the buffer member 50 of the embodiment is embedded in the size correction member 60 by forming the size correction member 40 of the first embodiment of a synthetic resin. In the implant fixture configuration of this other embodiment, it is natural that the coupling groove 21 is formed in the abutment 20 and the coupling protrusion 62 is formed in the size correction member 60.

In addition, the implant fixture is provided with means for further imparting a coupling force between the abutment 20 and the size correction member 60 and a fixing force (fixing force for preventing rotation of the size correction member).

This means is formed on the abutment 20 so that the fixing projection 61 protruding toward the abutment 20 on the inner circumferential surface of the size correction member 60 and the corresponding projection at the point opposite to the fixing projection 61. It consists of a fixing groove (22).

In the configuration of another embodiment as described above, since the size correction member 60 has the function of the buffer member 50, it is possible to shorten the manufacturing cost and the procedure time according to the decrease in the number of parts.
