It relates to a groove forming method.

Implants generally mean substitutes for restoring human tissues when they are lost, but in dentistry, artificial teeth are used to replace implants in place of natural or damaged natural teeth. It is widely used.

In the artificial tooth treatment, a drill groove is formed in the alveolar bone to be implanted using a drill to form a groove groove, and when the screw is rotated by a screwdriver while the fixture is inserted into the groove, the screw portion of the fixture is screwed into the groove. It is formed while being formed, and is completed by attaching the final prosthesis (artificial teeth) to the abutment after joining the abutment to the upper end of the fixture fixed to the alveolar bone.

The artificial tooth procedure includes bone removal surgery, and bone removal surgery generally refers to a process of making a recessed groove into which a fixture is fixed using a drill in the alveolar bone, and the basic principle of forming the recessed groove is an initial drill. The hole is made to be small and then the buried groove is enlarged to form an enlarged size that is almost equal to or slightly smaller than the diameter of the implant to be placed.

Looking at the conventional groove groove drilling technology disclosed in the prior art, in the Patent Publication No. 10-2009-0014835, the cutting temperature is made constant by the thrust load received from the center and the outer diameter of the drill by the multi-stage part formed with the cutting edges at several ends. There has been a prior disclosure of a dental implant drill using a multi-stage structure, which minimizes the process time and reduces the procedure time by making a filling groove for embedding the fixture with a single drilling procedure.

In addition, in Patent Publication No. 10-2009-0050769, the diameter of the cylindrical body provided with the cutting groove on the outer circumferential surface of the cylindrical body is gradually increased so that the entire body is shaped in multiple stages without drilling the replacement of the drill blade when drilling the alveolar bone. The technology related to the implant drill, which can be drilled from the diameter to the large diameter so that the implant can be easily operated, has been disclosed.

The above-described grooved home drilling technology has the purpose of performing the grooved home drilling operation more easily and quickly, but it was difficult to produce a home groove for poor alveolar bone.

In other words, the extraction of the maxillary anterior and the alveolar bone of the lower part and the lower alveolar bone should be formed in the lingual wall of the tooth extraction, but as shown in Figure 7 drill and lingual wall used for drilling at an inclined angle, the drill easily slides during the drilling operation It is difficult to drill in the right position, and this is delayed by the grooved boring operation, and also the problem of damage to the tooth extraction and surrounding gums as the drill slips.

Accordingly, the present invention has been conceived to solve the above problems, and more specifically, in drilling the grooved grooves at an inclination angle to the extraction and lingual walls, and drilled the grooved grooves quickly and precisely at the position set by one drilling. The present invention relates to a dental lingual wall drilling jig for preventing damage to surrounding alveolar bone and gums caused by slipping of a drill during operation, and a method of forming a grooved groove using the same.

At this time, the extension plate 12 is characterized in that the protrusion formed on the guide block 10.

In addition, the shock buffer 14 formed of an elastic body on the outer peripheral surface of the guide block 10 is characterized in that it is provided.

In addition, it is characterized in that the insertion depth control pin 30 is screwed to the lower end of the guide block 10 to adjust the length.

In addition, the guide hole 20 is characterized in that penetrating formed in at least two places at different inclination angles.

Then, the alveolar bone (2) and the alveolar bone (2) around the step of determining the perforated groove (3) punching position; Inserting the drilling jig into the extraction arm such that the drilling groove 3 is aligned with the guide hole 20; And inserting the drill 4 through the guide hole 20 to drill the recessed groove 3 at an inclination angle to the tooth extraction and the lingual wall.

According to the above configuration and action, the present invention drills through the guide hole in drilling the recessed groove at the inclination angle to the extraction and lingual wall, so that the drilled groove is quickly and accurately drilled at the position set in one drilling, and the drill during the drilling operation Damage to the surrounding alveolar bone and gums due to slipping is effective.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a dental lingual wall drilling jig and a method for forming a grooved groove using the same, in which the drilling jig should be faster when drilling grooves are formed on the extraction and the lingual wall in consideration of the extraction and surrounding alveolar bone conditions. It characterized in that it comprises a guide block 10, the guide hole 20 to be punctured in a simple and set position accurately.

Guide block 10 according to the present invention is formed so that the outer circumferential surface becomes narrower from the upper side to the lower side so as to be engaged with the foot and the fitting (1). The guide block 10 is formed of a material including durability and abrasion resistance, harmless to the human body, zirconium, hard synthetic resin, medical grade stainless steel, titanium, and the like and are fitted in consideration of extraction and shape (1). The contact area of the outer peripheral surface of the furnace is formed in a circular and oval cross-sectional shape.

And as the guide block 10 is formed so that the diameter becomes narrower toward the lower side, when the fitting and the fitting (1), the upper and lower parts are firmly engaged with the inner peripheral surface of the extraction and (1), the flow is prevented, at this time of the guide block 10 The upper and lower diameter differences are preferably formed in a size in which the upper diameter is expanded by 5% to 40% relative to the lower diameter in consideration of the common extraction and the average size.

In this case, the extension plate 12 protrudes from the upper portion of the guide block 10, where the expansion plate 12 is formed in a circular plate shape on the upper portion of the guide block 10 or locally protruded on one side as shown in FIG. 2. . Accordingly, when the guide block 10 is fitted to the extraction and the fitting 1, the extension plate 12 is protected to cover the skin tissue including the gums around, thereby preventing damage to the skin tissue during the drilling operation. ) Is a stopper so as not to be excessively inserted into the extraction and (1), there is an advantage that the extraction of the guide block 10 can be easily taken out by pulling the expansion plate 12 after completing the drilling operation.

In addition, an impact buffer 14 formed of an elastic body is provided on the outer circumferential surface of the guide block 10. The shock absorber 14 is formed of an elastic body including silicon and is disposed on the outer circumferential surface of the guide block 10 so as to be spaced apart from at least two places in the shape of a reducing frame as shown in FIG.

Accordingly, when the guide block 10 is fitted to the tooth and the tooth 1, the shock buffer 14 is elastically deformed while the outer diameter of the guide block 10 and the lingual wall shape of the tooth and the tooth are not coincident with each other. In close contact with the lingual wall of (1), the fixing force is improved, and vibration is absorbed during the drilling operation to prevent damage to the alveolar bone (2).

In addition, the insertion depth control pin 30 is screwed to the lower end of the guide block 10 is adjusted in length. Insertion depth control pin 30 is one end is screwed to the lower end of the guide block 10 as shown in Figure 4 and the other end is interviewed on the extraction and (1) the guide block 10 is more than the set depth during the drilling operation It is supported so as not to enter, where the insertion depth control pin 30 is rotated forward and backward according to the depth of the extraction and (1) to control the protruding length.

In addition, the ends of the insertion depth control pins 30 are formed in a spherical shape so as to prevent damages to the feet 1 and the end interviewed with the ends of the insertion depth control pins 30 due to the vibration and the pressing force applied during the drilling operation. It is preferable.

In addition, the guide hole 20 according to the present invention is formed with an entrance opening 22 in the upper portion of the guide block 10, it is formed through the inclination angle. The guide hole 20 is a through hole for rotatably supporting the drill in a state where the drill is inserted. The guide hole 20 is processed in general tolerance in consideration of the outer diameter size of the drill 4 so that the drill 4 does not flow during the drilling operation.

In addition, the guide hole 20 is preferably formed at an inclination angle of 10 to 40 degrees with respect to the central axis of the guide block 10 in consideration of the installation angle of the fixture implanted to fix the artificial tooth. Here, when the groove 3 is processed to more than 40 degrees, there is a problem that it is impossible to fix the artificial teeth through the fixture.

Accordingly, when the drill 4 is drilled in a state in which the drill 4 is accommodated in the guide hole 20 and supported, the sliding groove 3 is drilled in the correct position by preventing the drill 4 from slipping on the lingual wall at the initial entry. In addition, damage to the surrounding skin tissue due to the sliding of the drill 4 is prevented.
