Description

TECHNICAL FIELD

[0001] The present invention relates to a surgical kit combination for single drilling to prepare a hole in a bone for installing an implant, in particular to a complete implant assembly using a single stepped drill bit to match a specific implant profile. BACKGROUND

[0002] Implants in the medical field are of three types, the first is to replace a lost body structure, the second is to support a damaged body structure, and the third is to enhance an existing body structure, such as in dentistry for a lost tooth or atrophied alveolar bone, or in orthopedics for a damaged joint or fractured bone.

[0003] Referring to Figures 16A-16B As shown, with the rapid development of dental repair technology, some patients will use artificial tooth implants to repair defective teeth. Generally, the tooth implant surgery needs to first form a positioning point 80 on the surface of the alveolar bone by a positioning drill 70, then a first opening drill 71 with the smallest diameter is used to drill and cut the positioning point 80 to form a first hole 81, and a first detection piece 72 is placed to confirm whether the first hole 81 is skewed. If the direction of the first hole 81 is correct, a second opening drill 73, a third opening drill 74, and a fourth opening drill 75 with gradually increasing sizes are sequentially used to drill to form a second hole 82, so that the second hole 82 reaches the specified width and depth. Then, a second detection piece 76 is placed to confirm again whether the second hole 82 is skewed. If the direction of the second hole 82 is correct, a reamer 77 is used to ream the top of the second hole 82. After reaming, a tapping drill 78 is used to drill the second hole 82, so that the second hole 82 is changed into a tapered hole 83, and the surface of the tapered hole 83 forms a spiral track. Finally, a dental implant 79 is screwed into the alveolar bone to fix it by matching the spiral track.

[0004] The conventional method uses different drill bits to drill in several steps, which not only increases the operation time and difficulty, but also causes the alveolar bone at the implant site to generate a lot of heat energy due to the long time of continuous contact between the hole wall surface of the alveolar bone and the drill bit during drilling and cutting, resulting in the destruction of the structure of the alveolar bone.

[0005] In addition, in order to prevent the implant from shaking when implanted into the hole, the dentist usually selects a plurality of drill bits with appropriate sizes according to the implantation site and the size of the implant to form a hole with appropriate size on the alveolar bone. However, the size error and depth error of the hole generated by the traditional dental implant surgery are mainly dependent on the surgical experience of the dentist. If the size of the hole is too large, the implant will shake when implanted into the hole. In order to stabilize the implant in the hole, the dentist has to spend extra time to put the filler into the hole, which prolongs the operation time of implanting the implant into the alveolar bone. On the contrary, when the size of the hole is too small, a large amount of bone debris and heat will be generated during the implantation of the implant into the hole, which makes it difficult for the implant to be implanted into the hole, also prolonging the operation time of implanting the implant into the alveolar bone. SUMMARY

[0006] The main purpose of the present application is to provide a complete implant assembly that can immediately implant the implant into the bone after single drilling, so that dentists with different experiences can form the best fit between the implant hole and the implant, thereby shortening the overall operation time of the implant surgery and achieving tighter bone integration to improve the success rate of the surgery.

[0007] The secondary purpose of the present application is that the body profile of the implant is cut to the multi-stage stepped profile of the rotary bone drill, so that the threads of the implant can complete the tight engagement between the bone and the implant with the least amount of bone debris cutting, avoid the bone from being crushed and cracked due to lateral stress of the implant, and also reduce the bone burning of the bone.

[0008] Another purpose of the present application is that the rotary bone drill has a clear indication to help the dentist identify whether the drilling process is completed, and the drilling depth of the rotary bone drill each time can remain consistent, reducing human operational errors.

[0009] Another purpose of the present application is that the rotary bone drill and the implant both have a side cutting function that can be slightly deviated, so that the dentist can directly side cut and correct when the rotary bone drill or the implant is slightly deviated, and cold water can be added during the implantation process to maintain the drilling temperature of the rotary bone drill, and the bone debris generated by drilling can be quickly discharged at different stage positions of the rotary bone drill.

[0010] To achieve the foregoing object, the present application provides a complete set of implant assembly for single drilling, comprising a rotary bone drill and an implant, the rotary bone drill sequentially forms a rod, a stopper and a drill along a drilling direction, the rod is assembled to a rotary tool, the drill is configured with multiple steps of different diameters, a tip and at least one groove; the multiple steps are arranged between the stopper and the tip, the multiple steps collectively form a tapered ladder shape along the drilling direction; the tip forms a sharp point away from the side of the stopper, and the groove extends from the multiple steps to the tip along the drilling direction.

[0011] The implant has a body, an external thread and multiple side-cut grooves, the body has a cylindrical part and a conical part extending downward from the cylindrical part, a top end of the cylindrical part is provided with a slot, a bottom end of the conical part is shaped as a spherical surface, the external thread is formed on a ring conical surface of the conical part and a ring surface of the cylindrical part, the multiple side-cut grooves are formed by the external thread extending to the spherical surface, and the multiple side-cut grooves are penetrated inward from a fillet edge of the external thread to a part of the thickness of the conical part.

[0012] Wherein, the multiple steps are respectively configured with a bevel, so that the steps form a sharp part and a concave part; the conical part constitutes a conical profile, the circumference of which is aligned with the position of each concave part, the external thread has a blade part and a body part, the blade part is outside the step profile of the multiple steps, and a part of the body part is inside the step profile, so that the remaining part of the body part is outside the step profile; and the cylindrical part constitutes a rectangular profile, the circumference of which matches the step profile with the largest diameter.

[0013] In a preferred embodiment, an implant hole is formed by the rotary bone drill, and the implant is fixed in the implant hole, so that a gap is respectively formed between the implant and each concave part of the implant hole. The rotary bone drill can move along the drilling direction through the tip, and the rotary bone drill can be deflected along a side-cut direction intersecting the drilling direction through the multiple sharp parts.

[0014] The step has a ring groove to communicate with the at least one groove, and the ring groove is adjacent to the recess, so that the length of the bevel extends to the bottom of the ring groove, thereby increasing the length of the cutting edge of the tip along the side-cutting direction. The implant has a central rotation axis, and the outer thread includes a coarse thread on the surface of the tapered portion and a fine thread on the surface of the cylindrical portion. The side-cutting groove is only formed on the coarse thread when adjacent to the fine thread, and the side-cutting groove is formed on the coarse thread and the tapered portion when adjacent to the spherical surface, so that the depth of the side-cutting groove is close to the rotation axis.

[0015] The stopper is configured with a cylinder having a diameter greater than the plurality of steps, and the bottom surface of the cylinder is provided with a central plane connected to the steps and an annular plane around the central plane to form a stop structure; and the periphery of the stopper is provided with an annular mark.

[0016] In addition, the side-cutting groove extends along a spiral path from the spherical surface to the top end of the adjacent fine thread of the coarse thread, and the side-cutting groove and the coarse thread have the same spiral direction. Furthermore, a missing corner is formed between each step and each groove, so that a plurality of sharp edges are formed between the steps and the grooves.

[0017] In addition, the complete implant assembly further includes a guide plate having at least one opening, the depth of the at least one opening being greater than or equal to the height of the stopper, and the diameter of the at least one opening matching the diameter of the stopper, so that the stopper can be entirely entered into the opening from above the opening, and a part of the stopper can protrude below the opening.

[0018] The advantage of the present application is that the tapered portion and the cylindrical portion of the implant are both located inside the stepped profile of the rotary bone chisel, and the fine thread and the coarse thread of the implant are located outside the stepped profile, so that the implant can achieve close engagement between the bone and the implant with minimal cutting of bone chips, and lateral stress of the body of the implant can be avoided to cause the bone to be crushed and cracked. Thus, the implant can be fixed in the bone by single drilling, thereby shortening the operation time and achieving closer bone integration. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0036] The advantages and features of the present application will become apparent with the description of the specific embodiments and the accompanying drawings.

[0037] Reference will now be made to Figure 1As shown, the single drilling implant assembly of the present application comprises a rotary osteotome 1 for drilling and an implant 2 for implanting, wherein the rotary osteotome 1 must be installed on a rotary tool (not shown) so that the rotary osteotome 1 can be rotated by the rotary tool, and the rotary osteotome 1 will contact the alveolar bone 3 of a patient during rotation to form an implant hole 4, and then the implant 2 can be implanted into the implant hole 4 to achieve a torsional force value of more than 30 Newton between the implant 2 and the implant hole 4.

[0038] As shown in Figure 2 As shown, the rotary osteotome 1 sequentially forms a rod 10, a stopper 11 and a drill 12 along a drilling direction D (see Figure 4 ), the top of the rod 10 is provided with a cutting groove 101 forming a stop surface 102, and the cutting groove 101 is fitted on a rotating shaft of the rotary tool; the stopper 11 is configured with a cylinder 111 having a diameter greater than the rod 10 and the drill 12, the bottom surface of the cylinder 111 is provided with a central plane 112 connected to the drill 12 and an annular plane 113 around the central plane 112 to form a stop structure, and the periphery of the cylinder 111 is provided with an annular mark 114 in a different color to facilitate the doctor to directly confirm whether the drilling operation is completed.

[0039] The drill 12 is configured with a plurality of steps 121 of different diameters, a tip 122 and a plurality of grooves 123. As shown, the stopper 11 and the tip 122 are arranged with a first step 121a, a second step 121b, a third step 121c, a fourth step 121d and a fifth step 121e, wherein the first step 121a has the largest diameter and the fifth step 121e has the smallest diameter, so that the plurality of steps 121 collectively form a tapered stepped shape along the drilling direction D; the tip 122 is integrally formed on the fifth step 121e and forms a sharp point 122a on the side away from the stopper 11.

[0040] As shown in Figure 3 , the opposite sides of the drill 12 are respectively formed with a first groove 123a and a second groove 123b to penetrate the plurality of steps 121 and the tip 122, and the first groove 123a and the second groove 123b both extend along the drilling direction D to form a straight path.

[0041] However, the number of steps 121 and the number of grooves 123 are merely for the purpose of illustration and are not intended to be limiting, i.e. the number of steps 121 can be adjusted to three or four steps depending on the type of implant 2, and the number of grooves 123 can be set to one or more than three. In addition, the path of the grooves 123 can also be set to a spiral path (not shown).

[0042] As shown in Figure 2 , the first step 121a, the second step 121b, the third step 121c and the fourth step 121d are respectively formed with a ring-shaped inclined surface 124 at a lower corner position, the inclined surface is formed with a recess 125 near one end of another step 121, and the other end of the inclined surface 124 is formed with a sharp end 126. In this way, each step 121 is provided with an inclined taper design (inclined surface 124 and sharp end 122) that generates a downward cutting effect, so that the rotary bone drill 1 can move along the drilling direction D through the inclined taper design. In addition, each step 121 is provided with an internal recessed ring groove 127 to connect the first groove 123a and the second groove 123b, the ring groove 127 is located at the uppermost of the step 121 and can be adjacent to the recess 125, so that the length of the inclined surface 124 extends to the bottom of the ring groove 127.

[0043] As shown in Figure 4 and Figure 5 , when the alveolar bone 3 is initially drilled by the sharp end 122 of the rotary bone drill 1, bone debris will enter the first groove 123a and the second groove 123b, and then when the alveolar bone 3 is subsequently drilled by each inclined surface 124 of the rotary bone drill 1, most of the bone debris will directly enter the ring groove 127 adjacent to the inclined surface 124, and a small part of the bone debris will directly enter the first groove 123a and the second groove 123b, wherein the bone debris entering the plurality of ring grooves 127 will be moved to the first groove 123a and the second groove 123b, and finally the bone debris will be discharged through the exposed area of the first groove 123a and the second groove 123b which has not yet entered the implant hole 4.

[0044] In addition, the first groove 123a and the second groove 123b can also be cooled when the drilling temperature is too high, so that the temperature of the entire rotary bone drill 1 is reduced, avoiding the destruction of the alveolar bone 3 tissue caused by the high temperature of the rotary bone drill 1.

[0045] As shown in Figure 6As shown, when the fifth step 121e, the fourth step 121d, the third step 121c, the second step 121b, and the first step 121a of the drill bit 12 successively enter the alveolar bone 3, so that the stop member 11 contacts the top of the alveolar bone 3, the implantation hole 4 will sequentially form a first recess 41, a second recess 42, a third recess 43, a fourth recess 44, and a fifth recess 45 from the top to the bottom. In this way, a single rotating bone chisel 1 can achieve the result of traditionally requiring multiple sets of drill bits of different sizes to be drilled in turn, greatly shortening the operation time.

[0046] Please see Figure 7 As shown, when the physician finds that the rotating bone chisel 1 is drilled off-center, because the rotating bone chisel has the design of the tip 126, the rotating bone chisel 1 deflects along a side cutting direction intersecting the drilling direction through the plurality of tips 126, and because the length of the inclined surface 124 is extended to the bottom of the annular groove 127, the cutting edge length of the tip 126 along the side cutting direction increases.

[0047] Please see Figure 8 As shown, the implant 2 has a body 20 that can be fully inserted into the implantation hole 4. The body 20 has a columnar portion 21, a conical portion 22 extending downward from the columnar portion 21, and a spherical surface 23 located at the bottom end of the conical portion 22. A slot 211 for a specific tool (such as a dental handpiece or a manual wrench) is provided at one top end of the columnar portion 21. An annular surface of the columnar portion 21 and an annular conical surface of the conical portion 22 both extend outward and protrude an external thread. The external thread includes a fine thread 24 with a first pitch and a coarse thread 25 with a second pitch, wherein the second pitch is greater than the first pitch.

[0048] Furthermore, the body 20 and the coarse thread 25 are jointly formed with a plurality of side grooves 26. The plurality of side grooves 26 are located at equal intervals of the implant 2. The depth of the side groove 26 extends from a section of the circular edge of the coarse thread 25 inward to a portion of the thickness of the conical portion 22. The length of the side groove 26 extends from one end of the coarse thread 25 near the fine thread 24 to the spherical surface 23. The side groove 26 has a first depth at one end of the spherical surface 23, and the side groove 26 has a second depth less than the first depth at the other end near the fine thread 24, so that the depth of the side groove 26 gradually decreases.

[0049] As shown, the side-cut flutes 26 are formed along a helical path from the spherical surface 23 to the top end 251 of the adjacent fine thread 24 of the coarse thread 25, and the side-cut flutes 26 have the same helical direction as the coarse thread 25, so that the excess bone debris drilled out can be gradually pushed up along the helical path of the side-cut flutes 26 from the spherical surface 23 at the bottom of the implant 2 to the top end 251 of the coarse thread 25 to be discharged outward.

[0050] In addition, the implant has a central rotation axis, the side-cut flutes are formed only on the coarse thread adjacent to the fine thread, and the side-cut flutes are formed on the coarse thread and the taper adjacent to the spherical surface, so that the depth of the side-cut flutes is close to the rotation axis.

[0051] Referring to Figure 9 As shown in the schematic view of the implant 2 overlapping the drill 12, the taper 22 of the implant 2 is configured as a taper profile 220 that is tapered downward from top to bottom, and the pitch circle edge of the taper profile 220 will simultaneously contact the first recess 125a of the first step 121a, the second recess 125b of the second step 121b, the third recess 125c of the third step 121c, and the fourth recess 125d of the fourth step 121d, so that the taper profile 220 is entirely inside each step profile 128 (a first step profile 128a, a second step profile 128b, a third step profile 128c, a fourth step profile 128d, and a fifth step profile 128e) and aligned with the position of each recess 125, thereby allowing the taper 22 of the implant 2 to not generate a lateral pushing stress on the alveolar bone 3 when entering the implant hole 4.

[0052] The coarse thread 25 forms a first thread profile 250 on both outer sides of the taper profile 220, respectively, and the first thread profile 250 includes a plurality of cutting edge portions 252 and a plurality of cutting body portions 253, wherein the plurality of cutting edge portions 252 are respectively beyond the second step profile 128b, the third step profile 128c, the fourth step profile 128d, and the fifth step profile 128e, so that the cutting edge portions 252 will perform cutting on the implant hole 4 again when entering the implant hole 4; and the cutting body portions 253 are inside the second step profile 128b, the third step profile 128c, the fourth step profile 128d, and the fifth step profile 128e.

[0053] Furthermore, the cylindrical portion 21 of the implant 2 is configured with a rectangular profile 210 having a diameter larger than the tapered profile 220, the rectangular profile 210 matching the diameter of the first step 121a, and the fine thread 24 respectively forms a second thread profile 240 on both outer sides of the rectangular profile 210, wherein the second thread profile 240 entirely exceeds the first step profile 128a, and the fine thread 24 also performs cutting operations on the implant hole 4.

[0054] As shown in Figure 10 and Figure 11 When the implant 2 is rotated into the implant hole 4 by the rotary tool, the tapered portion 22 of the implant 2 forms a gap 5 with the first recess 41, the second recess 42, the third recess 43, the fourth recess 44, and the fifth recess 45, respectively, and the edges of the first recess 41, the second recess 42, the third recess 43, the fourth recess 44, and the fifth recess 45 have a sawtooth track 46 cut by the cutting edge portion 252. A portion of the gap 5 is filled by the shank portion 253 of the coarse thread 25, and the remaining portion of the gap 5 is filled with bone debris cut by the cutting edge portion 252 of the coarse thread 25, and other bone debris exceeding the capacity of the multiple gaps 5 enters the side cutting groove 26 and is discharged upward outside or downward into the bottom of the implant hole 4.

[0055] Since the alveolar bone 3 is not subjected to lateral stress, and the gap 5 between the implant 2 and the alveolar bone 3 is filled with bone debris when the implant 2 is implanted into the implant hole 4, the recovery between the bone debris and the alveolar bone 3 will be shorter than that of the conventional multiple drilling implantation method.

[0056] As shown in Figure 12 and Figure 13 In another preferred embodiment, the single-drilling complete implant assembly of the present application further comprises a guide plate 6 used in conjunction with the rotary bone chisel 1, the guide plate 6 having at least one opening 61, the depth of the at least one opening 61 being greater than or equal to the height of the stopper 11, and the diameter of the at least one opening 61 matching the diameter of the stopper 11, so that the stopper 11 can enter the inside of the opening 61 entirely from above the opening 61 to maintain straight-line movement, and when the annular flat surface 113 of the stopper 11 contacts the topmost part of the alveolar bone 3 and cannot move downward any more, a portion of the stopper 11 can protrude below the opening 61.

[0057] As shown in Figure 14As shown, the rotary osteotome 1 can be formed with an indented corner 129 between each step 121 and each groove 123, so that a plurality of sharp edges 129a are formed between the step 121 and the groove 123. In this way, when the rotary osteotome 1 is initially drilled in an oblique direction that is inclined to the drilling direction D, the rotary osteotome 1 can still produce lateral cutting by the indented corner 129, so that the rotary osteotome 1 can gradually be deviated from the oblique direction, thereby adjusting the rotary osteotome 1 back to the correct drilling direction D.

[0058] When the implantation surgery is performed using the complete implantation assembly of the single-drilling of the present application, first, the mouth of a patient is examined to obtain the condition of the teeth and alveolar bone 3 of the patient, and after confirming the condition of the alveolar bone 3, a drilling position and a drilling depth are determined.

[0059] Second, the number of steps of the rotary osteotome 1 and the size of the implant 2 are selected according to the actual needs and the drilling depth, so that the drilling member 12 of the rotary osteotome 1 matches the drilling depth and forms a tapered stepped shape, and the cylindrical portion 21 of the implant 2 matches the step 121 with the largest diameter, and the tapered portion 22 of the implant 2 aligns with the recess 125 of each step 121.

[0060] Third, the rotary osteotome 1 is aligned with the drilling position and the drilling direction D to contact the alveolar bone 3, and drilling is continued until the stopper 11 of the rotary osteotome 1 contacts the top of the alveolar bone 3, so that the alveolar bone 3 forms an implant hole 4 that is the same as the tapered stepped shape; thereby determining that the drilling process of the rotary osteotome 1 is completed, avoiding the inexperienced doctor drilling too deep to harm the patient's facial nerve, or drilling too shallow to cause the implant 2 to not be completely placed in the implant hole 4.

[0061] Fourth, after the rotary osteotome 1 is removed, the implant 2 is implanted in the implant hole 4 along the drilling direction D, and the cylindrical portion 21 and the tapered portion 22 of the implant 2 only contact the implant hole 4 without generating lateral stress, and the implant hole 4 is cut by the coarse thread 25 and the fine thread 24 to form a jagged track 46, and all gaps 5 between the implant hole 4 and the implant 2 are filled with bone chips, so that the torsion value between the alveolar bone 3 and the implant 2 is above 35 Newton. Finally, the slot hole 211 of the implant 2 is connected to an abutment, and an artificial tooth crown is installed on the abutment to complete the dental implantation surgery.

[0062] Although the above-mentioned embodiments are applied to dental implants, after understanding the technical features of the present application, it can be known that the present application can also be widely applied to general orthopedics, and should not be limited to dentistry.

[0063] Referring to Figure 15 As shown in the figures, the whole set of implant components of the present application can also be implanted into the facial bones using a fixed pitch external thread. As shown in the figures, the surface of the body 20 of the implant 2 is provided with a fixed pitch thread 27, and the side cut groove 26 can be extended upward from the spherical surface 23 to the cylindrical portion 21 of the body 20, and a top portion of the side cut groove 26 will form a spacing distance with the top surface of the cylindrical portion 21 (not shown in the figures).

[0064] The above description is only illustrative and is not restrictive, and those skilled in the art understand that many modifications, changes or equivalents can be made without departing from the spirit and scope defined by the claims, and all of them will fall within the protection scope of the present application.
