Description

Technical Field [0001] The present invention relates to a surgical instrument kit for accurate implant induction,

[0001] The present invention relates to a surgical instrument kit in which components used for implant surgery are housed integrally, and more particularly to a surgical instrument kit comprising a processing member, a plurality of carrier portions having a diameter corresponding to the plurality of drills, The present invention relates to a surgical instrument kit for implant precise induction implantation embedded in a surgical instrument case.

In general, an implant is a prosthesis that is used to replace a severely damaged tooth. The artificial tooth is formed by implanting an artificial tooth made of titanium or a titanium alloy into a missing part of a tooth to form an artificial tooth. It is a collective term for dental procedures that can lead to everyday life. The implant has a similar advantage to a natural tooth without damaging the surrounding teeth except for a tooth requiring a procedure, compared with a denture or bridge method.

The implant having the characteristics described above is firstly prepared by cutting the gums of the patient to be treated, exposing the alveolar bone, determining a position at which the implant is to be placed, drilling a predetermined position of the alveolar bone using a perforating tool such as a drill A fixture forms a perforation to be placed. When the inserted fixture is fused with the alveolar bone, the abutment and the artificial crown are combined with the fixture, and then the gum is covered, thereby completing the installation of the implant.

The task of determining successful implantation of such an implant is to drill the groove into which the fixture is to be inserted into the alveolar bone. This implies that the implant placement, depth and direction should be determined in consideration of various factors such as the overall condition of the teeth, the position of the teeth requiring the implant treatment, the condition of the alveolar bone, etc., and successful implantation can be expected. This is because when the perforation of the alveolar bone is unstable, the position, direction and depth of the implant can not be met.

This drilling operation for alveolar bone drilling has a difficulty in not only a beginner but also an expert, it is very difficult to precisely measure the depth and direction in the course of work. Especially for beginners who are not experienced with the procedure, it can be very difficult to measure the drilled depth without any special measurement steps during the procedure.

Further, when drilling a groove for placing a fixture, it is not easy to determine to what extent the drilling operation has been performed to a certain degree while the operator performs a drilling operation by applying a force to the drill. The drill may damage the nerves distributed in the alveolar bone. On the contrary, when the drilling operation is completed before reaching the predetermined drilling depth, the depth of the drilled groove is shallow, so that an excessive force is required to fix the fixture, thereby causing a screw around the groove to be damaged or fixed to the groove. the fixture can not be completely fixed and the re-operation is performed later.

In order to solve this problem, when a drill is used to directly open the alveolar bone by incising the gingival bone during the implant procedure, a stent is provided to accurately grasp the exact position and direction to perform the drilling operation To be used. Conventionally used stents are manufactured and used in the following manner. First, before implantation, impression material of rubber material is used to acquire the maxillary and mandibular musculature of the subject, and then gypsum is poured into the template to produce a gypsum model similar to that of the subject's maxilla and mandible. The gypsum model is then coupled to the artificial articulator to reproduce the jaw joint and upper and lower teeth similar to those of the recipient outside the mouth. Then, when a tooth is lost and a virtual tooth model made of a transparent material is prepared at a position where the implant is to be implanted, it is used as a stent.

A predetermined mark is displayed at a position where the drill is inserted among the stents thus completed, and a mark indicating the direction of perforation is made on the outside of the stent. Then, referring to the mark and the mark, the practitioner uses a drilling tool Thereby performing a drilling operation.

A guide member for guiding the rotation of the drill by inserting the drill into a hole drilled in the stent while the drill is inserted, and a guide member for guiding the rotation of the drill, And a manipulator kit including a handle for holding the manipulator by hand and allowing the guide member to rotate at a predetermined angle. The surgical instrument kit has been widely used for practicing implant placement on a patient or a stent installed in a gypsum model. For example, the handle may be rotated in one direction by coupling a distal end formed with a U-shaped groove for rotating the guide member to the guide member, but the practitioner may practice the implant operation through the surgical instrument kit , It is not only difficult to move the guide member in one direction by using the handle when the implant is applied to an actual patient, but also the joint state between the handle and the guide member becomes unstable.
