Description

Technical Field

[0001] The present invention belongs to the technical field of dental implant equipment, and more specifically, relates to a dental implant system. Background Art

[0002] In the field of dental implants, tooth loss or periodontal disease may cause gradual bone absorption and reduction, resulting in obvious depressions or insufficient bone mass in the implant area, which may cause the jaw to break easily after implantation, or affect the aesthetic appearance after the implant repair is completed. Currently, additional measures are usually required to increase bone mass or repair the jaw, such as using bone implantation (bone transplantation) or bone regeneration to increase bone mass, so that the bone mass in the implant area is suitable for implantation, and to improve the quality of the jaw and its aesthetic effect after repair. After the jaw is repaired, an implant can be implanted in the repair area to complete the entire dental implant process. Since additional bone repair surgery is required before dental implantation, this type of repair method is relatively cumbersome and has a long treatment cycle. How to efficiently and quickly complete this type of repair surgery has become a problem that needs to be urgently solved in this field.

[0003] In order to meet the above technical requirements, a dental implant system has been developed, which can simultaneously complete bone augmentation surgery and dental implant surgery, thereby improving treatment efficiency.

The dental implant system comprises: a base 1, a lifting column 2, and a lifting screw 3; a first threaded hole 11 is provided on the base 1; the lifting screw 3 comprises: a rod body 32 and a screw portion 31 having a first external thread 311; the screw portion 31 is arranged at one end of the rod body 32; the two ends of the lifting column 2 are respectively: a lifting end 21 and a mounting end 22 for mounting an external object to be lifted; the lifting end 21 is inserted in the first threaded hole 11 and can slide along the first threaded hole 11, and the mounting end 22 is located outside the first threaded hole 11; the lifting column 2 has a channel 23 for the rod body 32 to slide, and the rod body 32 is inserted in the channel 23; the screw portion 31 is located in the first threaded hole 11, and the first external thread 311 of the screw portion 31 is threadedly connected with the first threaded hole 11; the channel 23 and the first threaded hole 11 extend along a predetermined direction F respectively; in the predetermined direction F, the screw portion 31, the lifting end 21 and the mounting end 22 are arranged in sequence; the lifting end 21 is located on the path of the screw portion 31 moving in the predetermined direction F.

[0056] In this way, the base 1 is provided with a first threaded hole 11; one end of the lifting column 2 is the lifting end 21, and the other end of the lifting column 2 is the mounting end 22; the lifting end 21 is inserted in the first threaded hole 11 and can slide along the first threaded hole 11. When the first threaded hole 11 is vertically arranged (for example, the predetermined direction F is vertically upward), the lifting end 21 slides in the first threaded hole 11 to realize the lifting and lowering of the mounting end 22. The mounting end 22 can be used for mounting an external object to be lifted. The lifting and lowering of the mounting end 22 can realize the lifting and lowering of the external object to be lifted together; the lifting column 2 has a channel 23; the lifting screw 3 includes: a rod body 32 and a screw portion 31; the screw portion 31 has a first external thread 311, and the screw portion 31 is arranged at one end of the rod body 32; the screw portion 31 is located in the first threaded hole 11, and the first external thread 311 of the screw portion 31 is threadedly connected to the first threaded hole 11; the rod body 32 is inserted in the channel 23, and the rod body 32 can slide along the channel 23 slides; when the user screws the screw part 31 through the rod body 32, the screw part 31 can be lifted and moved along the first threaded hole 11; the channel 23 and the first threaded hole 11 extend along the predetermined direction F respectively; in the predetermined direction F, the screw part 31, the lifting end 21, and the mounting end 22 are arranged in sequence; the lifting end 21 is located between the screw part 31 and the mounting end 22; in the predetermined direction F, the lifting end 21 is located on the moving path of the screw part 31; so that when the user screws the screw through the rod body 32, the screw part 31 can push the lifting end 21 to move in the predetermined direction F during the process of rising and moving along the first threaded hole 11, and the lifting end 21 can raise its own position when moving in the predetermined direction F. The lifting end 21 can raise the position of the mounting end 22 during the lifting process. Since the external object to be lifted can be installed on the mounting end 22, the external object to be lifted can be lifted along with the mounting end 22, thereby realizing the lifting of the external object to be lifted, which is very convenient.

[0057] In the present application, when describing the lifting column 2 being raised or lowered, it is assumed that the predetermined direction F extends in the vertical direction; the screw portion 31, the lifting end 21 and the mounting end 22 are arranged in sequence from bottom to top.

[0058] For further information, see Figures 1 to 12 As a specific embodiment of the dental implant system provided by the present invention, a slide groove 111 extending along a predetermined direction F is provided on the inner wall of the first threaded hole 11, and a slider 24 is provided on the lifting end 21 and is slidably arranged in the slide groove 111. In this way, the slider 24 is slidably arranged in the slide groove 111 to keep the lifting end 21 stable during the lifting and lowering movement.

[0059] For further information, see Figures 1 to 12As a specific embodiment of the dental implant system provided by the present invention, there are multiple slide grooves 111 and multiple sliders 24; the multiple slide grooves 111 correspond to the multiple sliders 24 in number; the multiple slide grooves 111 are arranged in sequence along the circumferential direction of the first threaded hole 11. In this way, the multiple sliders 24 and the multiple slide grooves 111 cooperate with each other to keep the lifting column 2 more stable during the lifting and moving process.

[0060] Among them, “the circumferential direction of the first threaded hole 11 ” refers to the circumferential direction surrounding the first threaded hole 11 .

[0061] For further information, see Figures 1 to 12 As a specific embodiment of the dental implant system provided by the present invention, the slider 24 is in a long strip shape and extends along a predetermined direction F. In this way, the slider 24 is not easy to rotate when it is slid in the slide groove 111 .

[0062] For further information, see Figures 1 to 12 As a specific embodiment of the dental implant system provided by the present invention, an annular groove 112 extending along the circumferential direction of the first threaded hole 11 is provided on the inner wall of the first threaded hole 11; a snap ring 4 with a break point is clamped in the annular groove 112; when the external force applied to the snap ring 4 is removed, the outer diameter of the snap ring 4 is larger than the aperture of the first threaded hole 11, and the inner diameter of the snap ring 4 is smaller than the outer diameter of the lifting column 2; a positioning groove 211 for the snap ring 4 to be clamped is provided on the lifting end 21; the snap ring 4 is sleeved on the lifting column 2; when the lifting end 21 is raised to a predetermined position, the snap ring 4 is clamped in the positioning groove 211. In this way, the snap ring 4 has a break, the snap ring 4 can be opened to increase its outer diameter, and the snap ring 4 can also be closed to reduce its outer diameter; the snap ring 4 is clamped in the annular clamping groove 112 in the first threaded hole 11; when the external force is removed, the outer diameter of the snap ring 4 is larger than the aperture of the first threaded hole 11, so that the snap ring 4 clamped in the annular clamping groove 112 is not easy to be separated from the first threaded hole 11; when the external force is removed, the inner diameter of the snap ring 4 is larger than the outer diameter of the lifting column 2, so that when the snap ring 4 is sleeved on the lifting column 2, the snap ring 4 can be bundled on the outer surface of the lifting column 2; a positioning clamping groove 211 is opened on the lifting end 21, and when the lifting end 21 is raised to a predetermined position, the snap ring 4 is clamped in the clamping groove to prevent the lifting column 2 from continuing to rise.

[0063] In one embodiment, see Fig.10 In the process of placing the snap ring 4 into the annular groove 112, the snap ring 4 is closed under the action of external force, and then the snap ring 4 is placed into the annular groove 112. Under the action of external force, the snap ring 4' gradually closes to form a snap ring 4'', and then further closes to form a snap ring 4 and is placed into the annular groove 112.

[0064] In one embodiment, in order to prevent the lifting height of the lifting end 21 from being higher or lower than a predetermined position (wherein the lifting height being too low can be judged by the torque of the rotating rod body 32, and when the rod body 32 can be easily rotated, it indicates that the lifting height is too low), it is also avoided that the lifting first external thread 311 is completely screwed out of the first threaded hole 11.

[0065] For further information, see Figures 1 to 12 As a specific embodiment of the dental implant system provided by the present invention, the edge of the first threaded hole 11 has an installation chamfer 113 for guiding the clamping ring 4 to be clamped into the annular clamping groove 112. In this way, it is convenient for the user to enter the annular clamping groove 112 through the clamping ring 4 under the guidance of the installation chamfer 113.

[0066] In one embodiment, the snap ring 4 can be axially squeezed along the first threaded hole 11 so that one end of the snap ring 4 slides into the annular groove 112 along the installation chamfer 113 , and then the snap ring 4 automatically rebounds in the annular groove 112 , thereby completing the installation of the snap ring 4 .

[0067] For further information, see Figures 1 to 12 As a specific embodiment of the dental implant system provided by the present invention, there is a reserved gap between the bottom wall of the annular groove 112 and the clamping ring 4. In this way, the reserved gap can provide expansion space for the clamping ring 4 when expanding.

[0068] For further information, see Figures 1 to 12 As a specific embodiment of the dental implant system provided by the present invention, the surface of the lifting end 21 has a chamfered surface 212; when the lifting end 21 is inserted into the first threaded hole 11 from the outside and moves toward the clamping ring 4 along the first threaded hole 11, the chamfered surface 212 can be inserted into the inner side of the clamping ring 4 and open the clamping ring 4 so that the clamping ring 4 is sleeved on the lifting end 21. In this way, when the lifting end 21 is inserted into the first threaded hole 11 and moves toward the clamping ring 4, the chamfered surface 212 can first be inserted into the inner side of the clamping ring 4 and gradually open the clamping ring 4, and the opened clamping ring 4 can increase the inner diameter of the clamping ring 4, so that the clamping ring 4 can be sleeved on the lifting column 2.

[0069] For further information, see Figures 1 to 12 As a specific embodiment of the dental implant system provided by the present invention, the positioning slot 211 extends along the circumferential direction of the lifting column 2; the side wall of the positioning slot 211 close to the mounting end 22 is a guide wall 2111; the guide wall 2111 has an obtuse angle with the predetermined direction F. In this way, after the clamping ring 4 is clamped in the slot, if it is necessary to release the restriction of the clamping ring 4 on the descent of the lifting end 21, when the lifting column 2 is pressed down under the action of an external force, the clamping ring 4 can contact the guide wall 2111 on the positioning slot 211 and guide the clamping ring 4 to expand to leave the positioning slot 211.

[0070] Wherein: “circumferential direction of the lifting column 2 ” refers to the circumferential direction surrounding the lifting column 2 .

[0071] For further information, see Figures 1 to 12 As a specific embodiment of the dental implant system provided by the present invention, the cross-section of the clamp ring 4 and the cross-section of the annular clamp groove 112 are both rectangular. In this way, the clamp ring 4 can maintain its position in the annular clamp groove 112 stably.

[0072] For further information, see Figures 1 to 12 As a specific embodiment of the dental implant system provided by the present invention, the screw part 31 and the rod body 32 are an integral part. In this way, the connection between the screw part 31 and the rod body 32 is more secure.

[0073] For further information, see Figures 1 to 12 As a specific embodiment of the dental implant system provided by the present invention, the lifting end 21 has a first conical surface 213 arranged around the outside of the channel 23, and the screw portion 31 has a second conical surface 312 arranged around the outside of the axis of the rod body 32 and can be attached and sealed on the first conical surface 213. In this way, the first conical surface 213 and the second conical surface 312 can seal the gap between the first conical surface 213 and the second conical surface 312 after being attached, so as to prevent external liquid from entering the channel 23.

[0074] For further information, see Figures 1 to 12 As a specific embodiment of the dental implant system provided by the present invention, the end of the rod body 32 away from the screw portion 31 is a screwing end 321; the end surface of the screwing end 321 has a groove 3211 for cooperating with a screwdriver 54. In this way, the rod body 32 can be screwed by cooperating with the screwdriver 54 and the groove 3211.

[0075] For further information, see Figures 1 to 12 As a specific embodiment of the dental implant system provided by the present invention, the outer diameter of the rod body 32 is 0 mm to 0.05 mm smaller than the inner diameter of the hole 23. In this way, the rod body 32 is not prone to shaking when moving along the hole 23.

[0083] 3. Using the multifunctional implant expansion plane (i.e., a plane between the base 1 and the mounting end 22) as the transverse cutting plane and the right and left ends of the bone absorption as the longitudinal cutting plane, the jawbone 61 is cut to form a separate bone block 611.

[0084] 4. The multifunctional implant is controlled to rise to a specified height, so that the end of the implant drives the bone block 611 to separate from the jawbone 61, forming a long bone space of a specified height (ie, growth gap 62), and then the covering screw 51 is screwed into the telescopic implant.

[0085] 5. After the biomaterial and membrane are filled in the long bone space and the polished part of the bone block 611, the gums are sutured. The biomaterial and membrane can promote the natural regeneration of the jawbone 61 and make the separated bone block 611 fuse quickly with the jawbone 61. (Bone fusion is determined by taking a CT scan).

[0086] 6. Remove the covering screw 51 and screw the healing abutment and the repair abutment into the implant (for example, the implant abutment 52) ​​in sequence to complete the conventional denture restoration.

[0087] Based on the above steps, bone augmentation surgery and dental implant surgery can be completed simultaneously, thus meeting the above technical requirements.

[0088] In one embodiment, after the implant (i.e., the dental implant system) is installed, it can be used to repair the patient's jawbone 61, such as Fig.12 As shown, the lifting screw 3 is rotated by a screwdriver 54 to raise the implant to a specified height, and then the cover screw 51 is screwed in for a period of time to fuse the bone block 611 with the jaw 61, thereby completing the repair surgery of the jaw 61. The lifting screw 3 is provided with a first external thread 311, and the cover screw 51 is provided with a first threaded hole 11, and its first external thread 311 cooperates with the first threaded hole 11. After the cover screw 51 is rotated into the lifting screw 3, the third cone surface 2211 and the fourth cone surface 53 are squeezed, thereby completing the sealing, which can prevent foreign substances from entering the implant. The second cone surface 312 is provided on the screw portion 31 of the lifting screw 3, and the first cone surface 213 cooperates with the second cone surface 312, which is beneficial. In one embodiment, when the cover screw 51 is rotated, the cover screw 51 pulls the lifting screw 3, so that the first cone surface 213 and the second cone surface 312 are squeezed against each other, thereby completing the sealing, and preventing the internal substances of the human body from entering the implant.

[0089] In one embodiment, after the bone block 611 is fused with the jawbone 61, the covering screw 51 is removed and the implant base 52 can be installed in the concave cavity 221. Finally, the denture is fixed to the base to complete the dental implant restoration surgery. A screw head 55 is provided in the implant base 52, and the implant base 52 has a through hole 521 connected to the concave cavity 221; after the screw head 55 enters the through hole 521, it can be threadedly connected with the second external thread 3212 to fix the implant base 52 (the implant base 52 is clamped between the screw head 55 and the mounting end 22).

[0090] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
