Description

Dental Drill Set {DENTAL DRILL SET}

The present invention relates to a dental drill set, and more particularly to a dental drill set for the operation of bone deletion upon implantation of the implant.

An implant (dental implant) is a method of planting a new tooth by planting a fixture of a root-like structure in the jawbone where the root of the missing tooth is located. This method is more stable than fixed teeth because there is no damage to adjacent teeth and no secondary caries. In addition, when using a removable denture when a large number of teeth are missing, there is an uncomfortable feeling in the gums due to force on the periodontal tissue (gum), and due to the size of the denture, there is a severe foreign body in the oral cavity, but because the implant is the same structure as the teeth, There is no pain and foreign body, which can improve the quality of life and satisfaction of patients. Recently, implantation procedures for semi-permanently replenishing lost teeth have become common.

Surgery for implant placement 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 involves opening the gum at the part where the implant is to be inserted (soft tissue surgery), removing the cortical bone and reticular bone to form a base hole in the alveolar bone (bone deletion surgery), and then inserting an implant (medium). After the stabilization period has occurred, connect the abutment of the implant out of the gum so that the tooth can be inserted.If the gum is completely better and the implant is fixed to the bone, the processed tooth is manufactured. It is completed by coupling to the implant (base).

The combination of instruments used in soft tissue surgery and bone removal surgery in the implantation process is called an implant surgical kit. In this case, a dental drill is a tool used to drill a foundation hole during bone deletion surgery, and the dental drill is used in combination of various types of drills having various shapes and dimensions. Combinations of drills used in surgery are specifically referred to as drill sets.

1 and 2 are views showing sequentially a drill set used to form a base hole during an implant procedure, in accordance with the progress of bone removal surgery. In particular, FIG. 1 is a view showing a drill set and a process for forming a foundation hole for placing an implant 300 of an external fixture, and FIG. 2 shows an implant 310 of an internal fixture. A diagram showing a drill set and a process for forming a foundation hole for implantation.

Referring to Figure 1, to form a foundation hole for implanting the implant 700 of the conventional contoured body point drill (500; point drill), ∮2.0mm twist drill (510; drill2.0 / ∮3.0) mm pilot drill 520, ∮3.0 mm twist drill 530, ∮3.3 mm twist drill 540, countersink drill 550, tap drill 560, optionally used ) Were applied sequentially. Such a dental drill set was mainly used since the 1960s, when the implantation procedure was introduced, and was manufactured based on implantation with only the basal bone remaining. Therefore, the bone removal surgery using such a drill set is made by removing a solid basal bone little by little.

2, the point drill 600, ∮2.0mm twist drill 610, ∮2.0mm depth gauge (620) to form a foundation hole for implanting the implant 710 of the conventional inner mold body , 2.8mm twist drill (630), 2.8mm depth gauge (640), 3.5mm twist drill (650), 3.5mm depth gauge (660), 4.1mm tap drill (670) were applied sequentially. . In the bone removal surgery using the dental drill set, the number of drills is reduced by 5 times since the pilot drill 520 and the countersink drill 550 are not used, unlike the implant 700 of the above-described external media. (670) must be used. Such a dental drill set was mainly used since the 1980s, when the implantation process began to expand, and was manufactured based on the implant operation in the state of the alveolar bone of the tissue one step softer than the implant procedure applied since the 1960s.

On the other hand, Korean Utility Model Registration No. 0323647 and No.0254343 propose a type of dental drill for implant treatment, respectively. Utility Model No. 0323647 discloses a main body portion 10 (blade portion) such that the bottom surface which is not adjacent to the handle portion 20 (shank portion) is opened as shown in FIGS. It is expected to omit the countersink process by having a cylindrical shape having a base blade 11, a vertical blade 12 and a horizontal blade (13). And Utility Model Registration No.0254343 is a common body having a circular indentation 322, the center of the body 32 (blade), as shown in Figs. By forming the cutting edge 321 along the cut and cut outermost part, hole enlargement process using ∮2.0mm ~ ∮2.3mm drill, hole enlargement process using ∮2.8mm drill and hole front processing by final drill Expect to perform at the same time.

As mentioned above, various dental drill sets have been proposed for implantation, and they have been variously applied to bone removal surgery for implantation. However, such a conventional dental drill set is configured to form a base hole for implant placement in accordance with the criteria based on the most dense cortical bone (D1) or less dense porous cortical bone (D2), which makes up the majority of patients currently implanted When the base hole for implant placement is formed in the coarse reticular bone (D3) and fine reticular bone (D4), there is a big problem that the initial hole may be unsuccessfully expanded due to excessive expansion of the base hole.

On the other hand, the Republic of Korea Utility Model No. 0323647 and No. 025343 propose a specially designed dental drill, but the dental drill by the design of the electric is expected to omit the countersink process, but due to the configuration of the drill blade bone There is a problem that there is a concern that the damage and damage of the drill, and the drill by the later design is expected to form the foundation hole with only one drill when eliminating the bone, but the use of round burs and round drill is essential, and the occurrence of play in the formation of the foundation hole There is a problem that can not prevent the shaking of the drill.

As such, the dental drill set is used to form a foundation hole for a conventional implant procedure, so that it is configured and applied based on the hardest bone regardless of the type of bone, and thus, D4 bone and D3, which occupy most of bone during the implant procedure. It is not suitable for goals.

According to the Miss BMD, alveolar bone ranges from the smallest (D1) to the least dense (D4). Misch bone density classification is classified into dense cortical bone (D1), porous cortical bone (D2), coarse reticular bone (D3), fine reticular bone (D4). According to Misch, D1 bone is primarily a dense cortical bone, with holes and implants resembling those of oak or maple trees, while D2 bone is a dense and thick porous cortical bone in the coordination and in the rough reticular bone. Similar to drilling holes in firs, D3 bone is thinner porous cortical bone adjustment and fine reticular bone similar to drilling in balsa wood, D4 bone is fine reticular bone with almost no coordinating cortical bone. Similar to drilling. According to Misch, fine reticular bone (D4) constitutes the bulk of the bone volume adjacent to the implant.

Table 1 below shows the general anatomical location of the bone mineral density in experimental numbers (% frequency).

bone Anterior maxilla Posterior maxilla Anterior mandible Posterior mandible D1 0 0 6 3 D2 25 10 66 50 D3 65 50 25 46 D4 10 40 3 One

Table 1 shows that D1 bone is rarely found in the maxilla and mandible. D2 bone is the most common bone density developed in the mandible, and occupies more than two thirds of the mandible anterior, and D3 bone in the maxilla. It is very common that more than half of patients have D3 bones in the maxilla. Nearly half of patients have maxillary posterior teeth, while the maxillary anterior has 65% D3 bones and the mandibular teeth have almost D3 bones. And the softest D4 bones are most often found in the maxillary molar, and in particular, nearly two-thirds of patients show D4 bone in the molar or after maxillary sinus transplantation.

Thus, according to the Miss BMD position, the generalization of the treatment plan can be carefully established according to the location, and an error in the less dense bone treatment plan will allow the prosthesis to be planned with slightly more support than less support. safe. The maxillary anterior is usually treated with D3 bone, the maxillary posterior is treated with D4 bone, the mandibular anterior with D2 bone, and the mandibular posterior with D3 bone. More accurate determination of bone density can be determined by tactile feel in CT and implant surgery.

The present invention is suitable for D2 to D4 bone, which can be called the alveolar bone of general treatment patients based on the verification results, and can be processed to the alveolar bone of D1 bone by applying from the drill for processing the base hole on the D4 bone first when bone is deleted Dental drill sets. The implant is stable by providing a dental drill set for D2 to D4 bones to form a foundation hole appropriately according to the alveolar bone, unlike the conventional alveolar bone, regardless of the type of alveolar bone. To be treated.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 3A to 13, and like reference numerals denote like elements for performing the same functions in FIGS. 3A to 13. Meanwhile, the drawings and detailed descriptions of components that can be easily understood as a general dental drill and a drill set in each drawing are briefly or omitted, and the parts related to the present invention are illustrated. In particular, there are parts in which the size ratio between the elements is somewhat different or the sizes between the components coupled to each other are different. However, the differences in representation of the drawings are easily understood by those skilled in the art. A separate description is omitted.

3a and 3b are views for explaining a straight drill in a dental drill set according to a preferred embodiment of the present invention, Figures 4a and 4b is a tapered drill in a dental drill set according to a preferred embodiment of the present invention The drawings are for explanation.

3A to 4B, in the dental drill set according to the preferred embodiment of the present invention, the straight drill 10 and the tapered drill 60 are shank portions 20 and 70, necks 22 and 72, and blades. (40, 80). At this time, the shank portion (20, 70) is a part that is inserted and fixed to the power drill, etc. that are provided in various ways, the blades (40, 80) is a portion to grind the pubic bone to process the base hole for implant placement. The shank portions 20, 70, the neck portions 22, 72 and the blade portions 40, 80 are integrally formed with the same central axis. The straight drill 10 and the tapered drill 60 according to the present invention as described above may be applied to a stainless-based material (in this embodiment, the stainless steel-based YUS550 was applied) or other types of alloy materials and combinations thereof. The straight drill 10 and the tapered drill 60 are manufactured by machining a forged, rolled or drawn bar. In the embodiment of the present invention, the blades 40 and 80 of the straight drill 10 and the tapered drill 60 are formed to have a length L corresponding to the embedding bodies 280 and 290 of the implant to be implanted (this embodiment). In the example, they have the same length). The outer diameters of the blades 40 and 80 are formed to have an outer diameter D corresponding to the embedding bodies 280 and 290 of the implant to be implanted (in this embodiment, to have the same outer diameter). For example, the blades 40 and 80 of the straight drill 10 and the tapered drill 60 may have lengths of 8 mm, 10 mm, 12 mm, and 14 mm, as in the embodiment of the drill set of the present invention described below. This length (L) and the outer diameter (D) of the blades 40, 80 to correspond to the length (H) and outer diameter (D) of the implant medium, one or two drills (straight drill and tapered drill) Alternatively, by forming a small diameter straight drill and a final diameter straight drill), the base hole can be formed while drastically reducing the number of times of use of the drill compared to the conventional method. In other words, during the implant procedure, the depth of the root is checked through CT scan and before the procedure, the foundation hole is formed. At this time, if a drill having a length corresponding to the implant body of the implant to be implanted is used, the drill depth of one or two times is changed. It will form a foundation hole.

The straight drill 10 and the tapered drill 60 are formed such that the lands 44 and 86 of the blades 40 and 60 and the flutes 42 and 82 are generally parallel to each other (twist drill In contrast to). In this case, the lands 44 and 86 form outer diameters of the blades 40 and 60, and the grooves 42 and 82 are formed to have a constant radius with respect to the vertical cross sections of the blades 40 and 60. Such lands 44 and 86 and grooves 42 and 82 have no torsion angle similar to the flat drill used for the tool (the actual configuration is completely different). In tool drills, flat drills are used to drill deep and straight holes. The parallel formation of the blades 40 and 60 is very useful for drilling straight foundation holes, unlike the twist drills formed to have a conventional twist angle, and the problem of the conventional twist drill (screws on the machining surface of the foundation hole according to the twist angle). It is an advantage that it is possible to maintain the state of the machined surface of the foundation hole satisfactorily. The lands 44, 86 and the grooves 42, 82 formed in the blade portions 40, 60 of each drill are formed in three, corresponding to the outer diameter of the implant body of the implant generally used, ∮2.2mm, ∮3.3mm And ∮4.3mm to maintain the rigidity while having a suitable size to the outer diameter of the drill. Of course, if the stiffness equivalent to the blades 40 and 60 according to the present invention is maintained according to the material and size, the number of the lands 44 and 86 and the grooves 42 and 82 may be selectively applied in a plurality or more.

In the straight drill 10 and the tape drill 60 according to the present invention, the end inclined surfaces 48 and 92 are formed at the ends of the lands 44 and 86 so as to have a point angle at the ends of the blades 40 and 80. Chisel edges 46 and 90 are formed, respectively, and grooves 42 and 82 are thinned at the ends. The chisel edges 46, 90 and thinning 50. 94 having the point angles of the straight drill 10 and the tapered drill 60 of the present invention adopt the term because they have a similar action to that of a tool drill. There are some differences in its construction and operation. For example, in the straight drill 10 and the tape drill 60 according to the present invention, the chisel edges 46 and 90 are formed by the point angles of the end inclined surfaces 48 and 92. It is different from that formed by the lip relief angle, and the structure of the thinnings 50 and 94 is also different from the tool drill in that it is formed at each end of the three grooves 42 and 82. In the straight drill 10 and the tapered drill 60 of the present invention, the chisel edges 46 and 90 may have point angles (angles between the end slopes 48 and 92) having a range of 115 ° ± 5 °. However, the cutting resistance is preferably reduced to about 115 °. The thinnings 50 and 94 were formed inwardly at the ends of the grooves 42 and 82, so that the entry of the foundation holes was good and the cutting chips were segmented and the thrust resistance was reduced. Similar to the combination of X-type thinning).

Meanwhile, the tapered drill 60 according to the preferred embodiment of the present invention forms an intermediate inclined surface 88 which is inclined from the middle portion of the land 86 to the end portion (end inclined surface 88), and thus the outer diameter of the end of the land 86. It was made smaller than the outer diameter of this land front end. In this embodiment, the length L1 of the intermediate inclined surface 88 has an outer diameter of ∮3.15mm and mm3.8mm at the point where it starts to be inclined to correspond to the length L1 of the inclined portion of the implant 290 to be implanted. The outer diameter is set. The tapered drill 60 is such that the above-mentioned straight drill 10 effectively expands the foundation hole by allowing the pulverized product to be effectively discharged from the hard bones D1 and D2, while the base of the bone on the intermediate slope 88 In case of weakness, it slightly reduces the enlargement of the reticular bone where the porosity is very large so that the implant can be stably placed later. And it was formed to be bent in two stages in the horizontal land 44 of the end inclined surface 48 of the straight drill 10 according to the preferred embodiment of the present invention, which is the first end inclined surface 48 is a pilot ( pilot) function so that the direction of the foundation hole can be maintained correctly when replacing the drill.
