Description

Universal implant treatment kit using guide stent}

The present invention relates to a universal implant surgical kit using a guide stent, and more particularly, by optimizing the tool configuration of the kit required for the fixture placement procedure through the guide stent, it is universally usable and combined with a minimum number of tools. The present invention relates to a universal implant surgical kit using a guide stent capable of reducing the number of procedures.

In general, an implant is a prosthesis used to replace a badly damaged tooth, and an artificial tooth made of titanium or titanium alloy is implanted into the jaw bone to form an artificial tooth in a shape similar to that of the original tooth. It is a general term for dental procedures that can lead everyday life. The implant is a treatment method that has gained much attention recently because it has advantages similar to natural teeth, without damaging the surrounding teeth except for the teeth that need to be treated, compared to a method using a denture, a bridge, and the like.

The implant having the above characteristics is to first cut the gums of the patient to be treated to expose the alveolar bone and then determine the position to place the implant, and then drill a predetermined position of the alveolar bone using a drilling tool such as a drill at the position. Fixtures form perforations to be placed. When the implanted fixture is fused with the alveolar bone, the implant is completed by covering the gum after joining the abutment and the artificial crown to the fixture.

The operation that determines the successful placement in the treatment of such an implant can be said to be the operation of drilling the groove to be implanted in the alveolar bone. This is the first stage of implantation treatment. It is expected that the implant placement, depth, and orientation of the implant must be determined in consideration of various factors such as the overall condition of the tooth, the position of the tooth requiring implantation, and the condition of the alveolar bone. This is because the implantation position, orientation and depth of the implant cannot be met when the alveolar bone perforation is unstable.

The drilling work for drilling the alveolar bone is difficult for beginners as well as experienced workers to accurately measure the depth and direction in the working process. Especially for beginners who are not experienced in the procedure, it can be very difficult to measure the drilled depth without any special measuring step during the procedure.

In addition, when drilling a groove for placing the fixture into the alveolar bone, the operator may apply a force to the drill to drill the drilling operation to a certain depth because it is not easy to determine to what extent the drilling operation is currently performed. Drilling beyond the drill may damage nerves distributed in the alveolar bone. On the contrary, if the drilling operation is terminated before reaching the predetermined drilling depth, the drilled groove is shallow in depth, and excessive force is required to fix the fixture, which causes damage to the thread around the groove or the fixture to be fixed in the groove. The problem is that the fixture will not be completely fixed and you will have to retry later.

In order to solve this problem, in case of implantation, exposing the alveolar bone and exposing the alveolar bone, and then drilling directly using a drill on it, called a stent to accurately determine the exact position and direction to perform the drilling operation. Auxiliaries are used. Conventionally, the manufacturing process and the use method of the stent commonly used are as follows. First, before the implant procedure, using the impression material of the rubber material to obtain the sound of the maxillary and mandible of the subject and then pour gypsum on the sound to produce the same plaster model as the shape of the maxillary and mandible of the subject. The plaster model is coupled to an articulator to reproduce the jaw and upper and lower teeth, which are almost similar to those of the subject, outside the oral cavity. If a tooth is lost and a virtual tooth model is made of a transparent material at the position where the implant is to be treated, it is used as a stent.

In this way, a predetermined mark is displayed at the position where the drill is to be inserted among the completed stents, a mark indicating the direction to be drilled on the outside of the stent, and the operator uses a drilling tool such as a drill to refer to the mark and the marking. The drilling operation will be performed.

The guide member and the guide member for guiding the rotation of the drill by inserting a plurality of drills and a drilled hole in the stent with the drill inserted in order to perform the procedure for implantation of a series of implants more conveniently The procedure was performed using a surgical instrument kit that includes a handle that is coupled to hold the operator by the hand to rotate the guide member at a predetermined angle. The surgical instrument kit has been used in various ways for practicing implant placement for a patient or a stent installed in a plaster model. For example, the handle may be rotated in one direction by engaging the tip formed with the groove in the U-shape to rotate the guide member to the guide member, the practitioner to practice the implant procedure through the surgical instrument kit or In addition, when an implant procedure is to be applied to an actual patient, it is difficult to move the guide member in one direction using a handle, and the coupling state between the handle and the guide member becomes unstable.

The present invention has been made to solve the above problems, and by optimizing the tool configuration of the kit required for the fixture placement procedure through the guide stent to reduce the number of procedures according to the combination of the minimum number of tools and universally available It is an object of the present invention to provide a universal implant surgical kit using a guide stent.

The first cylindrical portion 81 is smaller than the inner diameter of the sleeve 70 and the outer diameter of the sleeve 70 is adjusted so that the operation can be performed at the corresponding diameter and depth of the sleeve 70 to facilitate attachment and detachment of the sleeve 70. It consists of a sleeve connector 80 comprising this large second cylindrical portion 82.

Here, the reamer 10 cuts the inner surface of the guide hole H formed in the guide stent G so that the correct diameter of the guide hole H is made, and at the same time, the cutting surface is constant and flat. When the drill or the sleeve 70 is drawn on the guide hole (H) is configured to be supported on the guide hole (H) stably and accurately without shaking.

The guide stent (G) is formed in the housing surrounding the buccal (buccal), lingual and occlusal (occlusal) of at least one tooth is formed in the guide hole (H) for the insertion of the fixture (F) Silver is manufactured by applying a resin of transparent material to cover the gingival and the appropriate number of teeth that have lost the tooth to a model that mimics the tooth shape of the subject.

Meanwhile, the reamer 10 is composed of a first reamer 11 used when not inserted and a second reamer 12 used when the sleeve 70 is inserted, and the first reamer 11 is used. The hole diameter difference between the guide holes H and the second reamer 12 is the thickness of the sleeve 70.

In general, the thickness of the sleeve 70 is 0.8 mm, and as shown in FIG. 3, the difference in drilling diameter between the first reamer 11 and the second reamer 12 is 0.8 mm.

In addition, the initial drill 20 is inserted into the guide hole (H) to be drilled about several millimeters at the precise center point of the treatment site where the fixture (F) is placed so that when drilling through the drill set (30) This will lead to an accurate drilling position.

The initial drill 20 is the shank portion 21 is coupled to a separate rotary tool for implants, the guide counterpart 22 is inserted into the guide hole (H) to the lower side of the shank portion 21 and is supported by rotation; It consists of a drill blade portion 23 in which drilling is performed on the bone tissue of the procedure site.

Here, the guide counterpart 22 is located in the guide part 22b and the guide hole H, which is rotated and accommodated in the guide hole H, so that the initial drill 20 is no longer inserted therein. It consists of the step part 22a.

At this time, the diameter of the guide portion 22b is the same as the diameter of the first reamer 11 and the diameter of the stepped portion 22a should be formed larger than the guide portion 22b.

In addition, the drill blade 23 is positioned between the first drill 23a and the first drill 23a and the guide counterpart 22 formed at the lower end to drill bone tissue at the treatment site and have a predetermined inclination angle. It consists of a second drill 23b for cutting the gum (gingiva).

Here, the tip portion of the first drill (23a) is formed so that the cross section is round, the sliding shape is prevented on the gum by the round shape of the end is possible drilling to the correct position.

In addition, the second drill 23b is to cut the gingiva of the treatment site by drilling, which can replace the process of removing the gingiva of the treatment site with a tissue punching drill (90), the gingiva with a tissue punching drill (90) This can solve the problem that the newly created gingival shape is not natural when it is completely healed after removal.

On the other hand, the drill set 30 is drilled by gradually increasing the diameter size according to the diameter and the insertion depth of the fixture (F) to be placed after drilling the initial drill 20, a plurality of drills according to the diameter and depth Drill set 30 according to an embodiment of the present invention is composed of four sets for each diameter and consists of a drill having a depth of three places for each set.

As shown in Figure 1 drill set 30 according to an embodiment of the present invention has a diameter of the drill blade portion 33, respectively, 2mm, 2.8mm, 3.5mm, 4.3mm four configurations and depths for each diameter The length of the drill blade is composed of three types.

If the diameter is 2mm, the depth consists of 16.5mm, 18mm, 19.5mm, and if the diameter is 2.8mm, 3.5mm, 4.3mm, the depth consists of 18.5mm, 20mm, 21.5mm.

In the case of the patient who needs to deepen the fixture placement position because the bone tissue is weak according to the bone tissue environment of the patient, the drilling should be done deeply, so that drilling of the drill set 30 having a large diameter and depth is required and the bone placement is strong and the fixture placement position is In the case of a relatively thin patient, the drilling is to be made thin, the drilling can be finished with a small diameter and thin drill set 30.

For example, as shown in FIG. 9, when the diameter of the fixture F is 4 mm, the drill of the drill set 30 is drilled to 2 mm, 2.8 mm, and 3.5 mm, as shown in FIG. 10. In the case of 5mm, the drill of the drill set 30 is drilled into 2mm, 2.8mm, 3.5mm and 4.3mm.
