Description

Drill unit for sinus membrane lift

The present invention relates to a drill unit for maxillary sinus elevation, and more particularly, to allow a stable operation of the maxillary sinus endocardium during perforation of the alveolar bone for implantation, and thus to prevent maxillary sinus endocardium damage. It's about the unit.

 Typically, implant (Implant) refers to a substitute to recover when the original human tissue is lost, but in the dentist means to implant artificial teeth. To replace the lost tooth roots (tooth root) is a procedure to restore the function of the tooth by planting the tooth root made of titanium (titanium), etc., which is not rejected in the human body in the alveolar bone out of the teeth, and then fixing the artificial teeth.

In the case of general prosthetics or dentures, the surrounding teeth and bones are damaged over time, but the implants do not damage the surrounding dental tissues, and they have the advantage that they can be used semi-permanently because they have the same function or shape as natural teeth and do not cause tooth decay.

Implants also enhance the function of dentures and improve the esthetic aspects of dental prosthetic restorations, as well as in single brace restorations, as well as in patients with partial and complete teeth. Furthermore, it disperses excessive stress on the surrounding pubic tissue as well as helps stabilize the teeth.

On the other hand, the implant success rate in the maxillary posterior part is known to be relatively low compared to the success rate in other parts, for example, the mandibular posterior part during such implantation procedure, because the maxillary posterior part is relatively weak in bone and has the maxillary sinus inside. This is because it is not easy to implant.

In other words, the maxillary sinus, located between the upper molar and the nose, above the upper molar and more precisely, is a space enclosed by the mucosa, which extends downward when physiologically lost. Due to the bone absorption due to the downward expansion of the bone amount to implant the implant is insufficient, which makes it difficult to implant the implant in the maxillary posterior molar. In this case, after forming a space by elevating the maxillary sinus lining, a bone graft material is implanted in the secured space, and implantation is implanted therein. Such methods include a vertical approach and a lateral approach.

First, the vertical approach is a method of securing a certain amount of residual bone in the implant site, and tapping the maxilla several times with a device called a chisel and hammer-shaped osteotomes to prevent damage to the maxillary sinus lining. Then, a little bit of bone graft material through the hole.

However, when using such a vertical approach, because the maxillary sinus lining cannot be seen directly during the procedure, the procedure takes a long time because the operation is performed very carefully while checking the process by X-rays.

In addition, the lateral approach is a method when the remaining bone of the implant site is very insufficient, forming a hole on the side of the maxillary sinus to elevate the maxillary sinus endocardium, and then implant the bone graft material through the hole. By the way, this method has the advantage that the procedure can be faster than the vertical approach, there is a concern that the edema may occur in the surgical site as well as the operation itself is difficult.

Therefore, in order to solve these problems, recently, maxillary sinus elevation using a general implant drill has been studied, and furthermore, it is actually applied. By the way, the maxillary sinus elevation using the general implant drill has the advantage that the maxillary perforation can be easily and quickly timed, but the maxillary bone can be irregularly cut instead of exquisitely cutting the maxillary perforation, and the tip of the implant drill is also maxillary sinus Injuries such as tearing of the maxillary sinus endocardium may occur in contact with the inner lining, which may cause a problem of failing to accurately elevate the maxillary sinus lining and securing sufficient space for implant placement.

Therefore, there is a demand for the development of a new drill tool for maxillary sinus lining that can not only accurately form a hole in the alveolar bone but also raise the maxillary sinus lining without damage.

Republic of Korea Patent No. 10-0906692 discloses a safety drill assembly for maxillary sinus endothelial elevation. The disclosed drill assembly includes a driver connector to which the shank is once connected to a drive source such as a power drill; A rotary cover accommodating the other end of the driver connector in one side and screwing a main cutting bar having a hollow shape in the other side; An upper cutting bar having one end inserted into the main cutting bar and received in the rotary cover, and the other end having a cutting blade; And an intermittent means for regulating the connection between the driver connector and the upper cutting bar in the rotary cover.

The technical configuration as described above has a problem in that the structure is relatively complicated and the diameter of the drill is increased because intermittent means for controlling the connection between the driver connector and the upper cutting bar is installed in the rotary cover.

 Korean Patent Registration No. 070374 discloses an implant drill for maxillary sinus elevation. The published implant drill has a cutting groove formed on the outer circumferential surface of the cylindrical body and has a central axis provided with a shank portion, and is mounted on a general dental handpiece. The protruding member is elastically installed on the body and emerges in the longitudinal direction from the drill end. Have

Such a drill has a problem in that the end of the protruding member does not have a function of drilling the maxilla, and thus the drilling operation of the portion corresponding to the protruding member is not smoothly performed. This is a relatively large problem.

In the hollow portion 31 of the first drill member 30, the slide rod 41 is rotatably installed and rotatable, and at one end portion of the slide rod 41 exposed to the outside of the hollow portion 31. The second drill member 40 is installed, and the other end of the slide rod 41 is exposed to the space 22. The diameter of the second drill member 40 is formed relatively smaller than the diameter of the first drill member 20, the second cutting blade may be formed on the outer peripheral surface of the second drill member (40). In addition, a tip blade for cutting is formed on the upper surface of the second drill member 40, so that the endothelial membrane is not damaged by instantaneous rotation (the moment when the rotation is stopped while the second drill member is separated from the first drill member). It is preferable to form a cutting edge angle small.

The first rod member 30 and the second drill member 20 are elastically biased in the space portion 22 of the main body 20 by elastically biasing the slide rod 41 in the outward direction of the first drill member 30.

Referring to Figures 5 and 6 the operation of the maxillary sinus endothelial elevation drilling unit according to the present invention configured as described above is as follows.

First, surgery for implantation depends on the type of implant (system), but the most commonly used screw implants include soft tissue surgery and bone removal surgery. This implantation process consists of a soft tissue surgery to open the gums of the implant portion, and bone removal surgery to remove the cortical bone and reticular bone to form a base hole in the alveolar bone.

In order to perform the bone removal surgery process to form the base hole in the maxilla, while pressing and driving the shank portion 21 to the chuck for driving is pressed while the second drill member 40 in contact with the base hole forming portion of the maxilla. In this way, as the slide rod 41 elastically supported by the spring 52 of the elastic unit 50 is retracted, the first side of the side corresponding to the rotational force transmission protrusion 61 formed on the second drill member 40 is supported. Coupling grooves 62 formed in the drill member 30 is coupled to rotate the first and second drill members 20, 30 are integrated. The first and second drill members 20 and 30 that are integrally rotated puncture the maxilla. In this process, the first and second drill members 20 and 30 first penetrate the hard cortical bone and then drill the soft reticular bone, and then drill the hard cortical bone in the lower maxillary sinus. Since the diameter of the second drill member 40 is located at the tip of the drill unit, it first passes through the cortical bone. Since the pressure for drilling is not applied to the second drill member 40 passing through the cortical bone, the slidable rod 41 is raised by the spring 52 elastic force of the elastic unit 50, and the first drill member 20 The second drill member 40 is raised relative to the rotation force transmission protrusion 61 and the coupling groove 62 is separated and the rotation is stopped. In this process, the endothelial membrane of the maxillary sinus is prevented from being damaged by the second drill member 40.

When the first drill member 20 having a relatively large diameter passes through the cortical bone during this operation, the first drill member 20 is idling because the endothelial membrane is supported by the first drill member that is not rotated. do. Since the endothelial membrane is lifted by the second drill member 40 which does not rotate even when the first drill member 20 is further advanced, the endothelial membrane can be prevented from being damaged by the first drill member 20.

When the first drill member 20 and the second drill member 40 are separated, and the first drill member 20 is idling, the operator recognizes this, and it can be seen that the formation of the foundation hole for implantation is completed. have.

As described above, the drill unit for maxillary sinus levitation of the present invention prevents damage to the periosteum in the maxillary sinus during perforation of the base hole for implantation, thereby fundamentally preventing the inflammation caused by periosteal injury.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments thereof are possible.

Therefore, the true scope of protection of the present invention should be defined only by the appended claims.

Drill unit according to the present invention is widely available for drilling operations for dental treatment.
