Description

Apparatus of cylinder for dental implant

The present invention relates to an implant cylinder device, and more particularly, to an implant cylinder device in which the precision of an implant procedure is improved.

In general, dentures or prostheses are oral periodontal tissues that artificially restore appearance and function by replacing defective natural teeth.

In detail, when left in a state where natural teeth are lost, distortion of the teeth occurs in the adjacent teeth and the opposing teeth of the missing tooth, resulting in a deformation of the facial shape, and the chewing function is deteriorated, which causes inconvenience in daily life. Moreover, when the loss state of natural teeth lasts for a long time, the alveolar bone surrounding the missing tooth is absorbed into the body, making it difficult to install artificial periodontal tissue.

In this case, the denture or prosthesis may be installed inside the oral cavity to restore the chewing function and to prevent deformation of the periodontal tissue, and may be divided into partial / complete denture and partial / complete prosthesis according to the number of missing teeth.

On the other hand, the denture is installed to be bonded to the surface of the gum by applying a dental adhesive to the inner surface side groove, the prosthesis may be installed through a fixture placed in the alveolar bone. At this time, since the denture causes deformation of the gum or a large amount of foreign body as the gum is supported, the amount of prosthetics supported by the alveolar bone is increased recently.

Here, the prosthesis is formed with a coupling hole in which the cylinder device is embedded. In detail, the prosthesis may be installed by forming a perforation in the alveolar bone, implanting a fixture in the formed perforation, and then attaching the abutment and the cylinder device to the implanted fixture.

In this case, the cylinder device is coupled to the upper portion of the abutment directly coupled to the fixture may be embedded in the coupling hole.

The cylinder device and the abutment may be provided in plural places according to the size of the prosthesis, and the prosthesis may be stably installed as each cylinder device is matched to the abutment coupled to each fixture. Can be.

Here, after fastening the cylinder device to the fixture, in consideration of the manufacturing error is placed in the oral cavity the prosthesis is formed primarily of a wide size coupling hole.

Then, when the coupling hole is expanded according to the positional deviation of the cylinder device, and the cylinder device is completely inserted and the machining of the coupling hole is completed in a penetrable size, the prosthesis is temporarily fixed to a predetermined installation position, and then between the coupling hole and the cylinder device. Through the process of injecting and curing the dental resin into the coupling hole and the cylinder device, the initial installation of the prosthesis was completed.

However, when the resin is injected between the coupling hole and the cylinder device, as the resin flows into the gums, it hardens on the gums, causing a foreign body, and when the re-separation of the prosthesis is required, the procedure is complicated and the convenience of the procedure is deteriorated.

That is, the distance from the planar portion of the outer surface of the restraint step 12 to the coupling hole 301 and the distance from the edge of the outer surface of the restraint step 12 to the coupling hole 301 may be different from each other. .

Through this, a part of the resin (r) is primarily blocked by the restraint step 12 formed on the outer circumference of the cylinder body portion 10, so that the target archery is formed along the surface of the cylinder body portion 10 ( 2) Flow and penetration into the surface can be prevented.

Therefore, since the resin (r) is prevented from flowing and hardening to the surface of the target archery (2), the resin (r) is partitioned in the state partitioned from the target archery (2), thereby significantly improving the safety of the procedure. Can be.

Furthermore, since the outer surface shape of the restraint step 12 is formed in a polygonal cross section, it can be easily mounted through a surgical tool such as tweezers when the implant cylinder device 100 is installed in the target arch of the prosthetic subject 2. The convenience of the procedure can be improved.

In addition, each of the bent edges of the restraint step 12 is preferably formed so that the edge portion 12a is bent inward in the radial direction so that the tip portion is curved. Here, as the outer surface of the restraint step 12 is bent in a polygonal shape, each corner formed may be cut to form a smooth curved or flat surface.

Can be significantly improved.

On the other hand, it is preferable that the support step 13 protruding radially outward from the cylinder body 10 is formed below the restraint step 12. Here, the outer diameter of the support step 13 may be formed above the outer diameter of the restraint step 12.

Here, even if the outer diameter of the support step 13 is formed to be the same as the outer diameter of the edge portion 12a of the restraint step 12, the outer diameter of the polygonal flat portion of the restraint step 12 is the outer diameter of the edge part 12a. It can be formed smaller.

Accordingly, the resin r injected into the inner circumference of the coupling hole 301 of the denture prosthesis 300 may be injected and cured over the outer circumference of the extension part 20 and the outer circumference of the restraint step 12. have.

In addition, the outer diameter of the support step 13 may be formed to substantially correspond to the inner diameter of the coupling hole 301 of the denture prosthesis 300.

Here, a seating portion is formed radially outward along the circumferential direction on one side of the abutment (a) may be seated on the lower edge (13a) of the cylinder body portion (10). Accordingly, as the cylinder body 10 is seated on the seating portion of the abutment (a), direct contact between the cylinder body portion 10 and the target archery 2 may be prevented.

The rubber dam part d covers the surface of the target arch 2 as the insertion hole e of the rubber dam part d is inserted into the fitting groove 14 of the cylinder body 10. Can be arranged.

In addition, when the rubber dam part d is disposed on the surface of the target archery 2, the coupling hole 301 of the denture prosthesis 300 may be inserted into an outer circumference of the cylinder device 100 for the implant. In this case, the denture prosthesis 300 may be seated on an upper portion of the rubber dam part d inserted into the fitting groove 14.

Accordingly, as the bonding area increases due to the resin (r) injection between the denture prosthesis 300 and the cylinder device 100 for the implant, the bonding force may be significantly increased, thereby improving the precision of the procedure.

In addition, the insertion hole (e) of the rubber dam part (d) in the fitting groove 14 formed between the restraint step 12 and the support step 13 formed on the outer circumference of the cylinder body part 10 May be intervened and intervened. Accordingly, the penetration of the resin into the surface of the target archery 2 can be prevented in advance, thereby significantly improving the safety of the procedure.

Furthermore, since the insertion hole e of the rubber dam part d is maintained in the fitting groove 14, the position of the rubber dam part d is maintained even after installation of the denture prosthesis 300 in the implant cylinder device 100. The ease of procedure can be improved.

On the other hand, the extension portion 20 is formed integrally extending in the upper portion of the cylinder body portion 10, the through hole 21 in communication with the fastening hole 11 in the longitudinal direction therethrough penetrates in the longitudinal direction Preferably formed.

Here, the extension part 20 may be formed to be smaller than the length of the coupling hole 301 of the denture prosthesis 300. That is, the vertical length of the implant cylinder device 100 may be smaller than the vertical length of the coupling hole 301 of the denture prosthesis 300.

Accordingly, the coupling hole 301 of the denture prosthesis 300 is inserted into the cylinder device 100 for the implant, and resin (r) is injected into the coupling hole 301 to extend the extension portion 20. ) May not be exposed to the outside of the coupling hole 301.

In addition, the extension part 20 may be formed in a hollow shape, and the through hole 21 may be formed to have a uniform inner diameter along the longitudinal direction unlike the fastening hole 11. Here, the inner diameter of the through hole 21 may be formed corresponding to the outer diameter of the head portion of the fastening screw 13.

Here, the fastening screw 13 means a member inserted into the through-hole 21 to mediate the fastening between the implant cylinder device 100 and the abutment (1).

At this time, the fastening screw 13 is formed with the head portion extending radially outward in the upper end portion, a screw thread may be formed to be inserted into the upper inner circumferential groove (b) of the abutment (a) on the lower outer circumference. .

Accordingly, the fastening screw 13 may be inserted from the upper portion of the through hole 21 to be inserted into the inner circumferential groove b of the abutment a. Through this, the abutment column 1 including the implant cylinder device 100 and the abutment (a) can be fastened and fixed.

In addition, a head portion of the fastening screw 13 having a lower end coupled to an upper inner circumference of the abutment 1 is caught on the inner circumference of the implant cylinder device 100 between the fastening hole 11 and the through hole 21. Preferably, the locking step 22 is formed.

Here, the engaging step 22 corresponds to the extended outer diameter of the head portion of the fastening screw 13 at the boundary between the fastening hole 11 and the through hole 21 in the radially inward direction along the circumferential direction. It is preferred that the depression is formed.

Accordingly, the head of the fastening screw 13 inserted into the through hole 21 is caught by the locking step 22, and the thread of the lower outer circumference of the fastening screw 13 is removed from the abutment a. Can be inserted into the inner circumferential groove (b).

As a result, the locking step 22 is prevented from being separated from the abutment 1 as the cylinder device 100 for the implant is prevented from being caught by the head of the fastening screw 13 so that the mutual fastening force can be maintained firmly. have.

In addition, after the fastening screw 13 is inserted into the through hole 21 and fastened, it may be cured as resin or the like is injected into the through hole 21. In this case, when the fastening screw 13 is required for reoperation, the fastening screw 13 may be separated from the inside of the through hole 21 as the operator removes the cured resin.

On the other hand, the outer periphery of the extension portion 20 is preferably formed in the cutting guide portion 23 is formed with a cutting line in multiple stages along the longitudinal direction to adjust the length corresponding to the vertical height of the denture prosthesis 300.

Here, the cutting guide portion 23 preferably includes a plurality of protrusions 24 protruding radially outward in the circumferential direction, and a plurality of recesses 25 recessed inward in the radial direction in the circumferential direction. Do.

In addition, the protrusions 24 and the recesses 25 are preferably alternately formed along the longitudinal direction of the extension part 20. That is, it is preferable that the outer circumferential surface of the extension part 20 is formed in an uneven shape as the protrusion part 24 and the recessed part 25 are alternately sequentially.

Accordingly, as the protrusions 24 and the recesses 25 are alternately disposed on the outer circumference of the extension part 20, the resin is filled in the gap between the coupling hole 301 of the denture prosthesis 300 ( r) may be filled into the depression 25. As a result, the bonding area between the denture prosthesis 300 and the extension portion 20 may be significantly increased as the bonding area with the resin r is increased.

In addition, although not shown in the drawing, the cutting line may be formed in a plurality of places along the circumferential direction on the outer circumference of the extension portion 20 in which the depression 25 is formed. In this case, the cutting line may be recessed along the circumferential direction to provide a guideline that is cut when the operator adjusts the length of the extension part 20 corresponding to the vertical height of the denture prosthesis 300.

Accordingly, since the length of the extension part 20 in which a plurality of cutting lines are formed along the circumferential direction of the outer circumference thereof is easily cut and adjusted in correspondence with the vertical height of the denture prosthesis 300, the ease of the procedure piece can be significantly improved. have.

Furthermore, as the cutting line is recessed along the circumferential direction on the outer circumference of the extension part 20, the cut profile cross-section is formed substantially uniformly, thereby improving accuracy.

On the other hand, the outer circumference of the extension portion 20 adjacent to the cylinder body portion 10 in the circumferential direction so that the insertion hole (e) of the rubber dam portion (d) is easily moved when inserted into the outer circumference of the cylinder body portion (10) It is preferable to form a smooth curved flat surface 26 along the.

Here, when the flat surface 26 is not formed on the outer circumference of the extension portion 20 and the protrusion and the depression portion are sequentially formed, the rubber dam portion d inserted from the upper portion of the extension portion 20 is inserted. There is a fear that the ball e is caught in the protrusion.

Therefore, the insertion hole e of the rubber dam part d is easily moved along the flat surface 26 formed on the outer circumference of the extension part 20 adjacent to the cylinder body part 10 so that the fitting groove ( 14) can be attached and detached.

As a result, when the resin (r) is injected and cured between the coupling hole 301 and the extension part 20 of the denture prosthesis 300, the adhesive hole decreases due to the insertion hole e of the rubber dam part d. Since it is prevented in advance, the convenience of the procedure can be significantly improved.

On the other hand, the outer peripheral side of the extension portion 20 is preferably formed at least one or more decut portion 27 in the longitudinal direction. In some cases, the decut portion 27 may be formed on an outer circumference of the extension portion 20 on which the protrusion portion 24 is formed. Here, the decut portion 27 may be formed in a shape bent into a flat surface, it may be formed recessed concave in the radial direction.

Accordingly, the ease of use may be remarkably improved since at least one or more of the decut parts 27 formed in at least one longitudinal direction on the outer circumferential side of the extension part 20 may be easily mounted through a tweezer or the like.

In addition, the outer diameters of the cylinder body 10 and the extension part 20 are preferably formed below the inner diameter of the coupling hole 301. Accordingly, as resin (r) is injected and cured between the outer circumferences of the coupling hole 301 and the extension part 20, the denture prosthesis 300 and the cylinder device 100 for the implant may be coupled to each other. Can be.

In addition, the outer diameter of the extension portion 20 may be formed to be less than the outer diameter of the cylinder body (10). Furthermore, the outer diameter of the restraint step 12 may be formed to exceed the outer diameter of the extension part 20, and the outer diameter of the support step 13 may be formed beyond the outer diameter of the restraint step 12. .

The outer diameter of the support step 13 may be formed to substantially correspond to the inner diameter of the coupling hole 301 of the denture prosthesis 300. Of course, the outer diameter of the support step 13 may be smaller than the inner diameter of the coupling hole 301 of the denture prosthesis 300.

Accordingly, a resin r filled between the cylinder device 100 for the implant and the coupling hole 301 of the denture prosthesis 300 is formed at the upper portion of the cylinder body 10 of the fitting groove 14. It can be cured after being injected over the perimeter.

Therefore, as the insertion hole e of the rubber dam part d is frictionally interlocked, it is swept away so that the edge of the insertion hole e is not caught by the central portion in the longitudinal direction of the cylinder device 100 for the implant. Because it is precisely embedded in the), the precision of the procedure can be remarkably improved.

Accordingly, as the bonding area and height of the resin (r) injected between the outer circumference of the cylinder device 100 for the implant and the coupling hole 301 of the denture prosthesis 300 are increased, the mutual bonding force is remarkably improved. Can be.
