Description

Technical Field

[0001] The invention relates to the technical field of dental implantation, and in particular to an implant surface forming bur. Background Art

[0002] Oral implant restoration is a method of restoration that more and more people are choosing after losing their teeth. Oral implants are also called dental implants, or artificial tooth roots. They are implanted into the jawbone at the location of the missing tooth through surgery. After the upper wound heals, a prosthetic tooth is installed on top of it to complete the restoration of oral function and aesthetics.

[0003] A common complication in oral implant restoration is peri-implantitis, which leads to the failure of the bone connection between the implant and the alveolar bone, and eventually causes the implant to fall off. The main cause is the accumulation of plaque on the implant, especially at the thread of the implant surface. Due to the lack of clean water channels, the more structured the implant surface, the easier it is for plaque biofilm to grow, and the more difficult it is to clean thoroughly.

[0004] Implantoplasty is a mechanical modification of the implant surface, including the removal of implant surface threads and surface polishing. Experiments and clinical practice have shown that implantoplasty has a significant effect in reducing peri-implantitis bleeding, reducing probing depth, increasing the attachment level of periodontal tissue around implants, and increasing short- and medium-term bone stability.

[0005] At present, ordinary diamond turning needles are commonly used in clinical practice to perform implant surface shaping surgery, but this type of needle has the following defects: 1. Ordinary diamond turning needles are limited by their own shape and local space, and are prone to incomplete cleaning, leaving contaminated areas; 2. The surrounding soft and hard tissues are damaged during the shaping process; 3. The existing turning needles are not compatible with the shape of the implant, the cutting efficiency is low, and the clinical work time is long; 4. The shedding of diamond particles affects the later bone regeneration and the bone integration between the implant and the alveolar bone; 5. When the thread on the implant surface is polished, the local temperature is too high, which destroys the activity of the implant surface coating. Summary of the invention

[0006] In view of the deficiencies in the above-mentioned prior art, the present invention provides an implant surface shaping needle, which is matched with a dental high-speed mobile phone to solve the problems of insufficient polishing, damage to surrounding soft and hard tissues, low work efficiency, shedding of diamond particles and excessive surface temperature when using traditional diamond abrasive needles in implant surface shaping surgery.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A surface forming turning needle for an implant, characterized in that the turning needle comprises a connecting structure, a stabilizing structure, and a polishing layer; the stabilizing structure consists of a top beam, a support arm, and a bottom beam; the two support arms are symmetrically installed at both ends of the top beam, and the bottom beam is symmetrically installed at the bottom ends of the two support arms; the relative inner side surfaces of the two bottom beams are respectively arranged perpendicular to the top beam, and the polishing layers are respectively arranged on the relative inner side surfaces of the two bottom beams; the center of the top beam is connected to a motor mobile phone through the connecting structure; the motor mobile phone drives the stabilizing structure to rotate through the connecting structure, and the polishing layer contacts and rubs with the implant thread for implant forming.

[0009] Furthermore, the top beam and the bottom beam are respectively vertically connected to the support arm.

[0010] Furthermore, the two support arms are symmetrically installed at two ends of the top beam at a predetermined angle ∠1, and the bottom beam is a conical structure extending upward at a predetermined cone angle ∠2.

[0011] Furthermore, the predetermined included angle ∠1 is 68 to 90°, and the predetermined cone angle ∠2 is 0 to 22°.

[0012] Furthermore, a cleaning structure is also provided in the needle, and the cleaning structure is composed of a first water channel provided at the center of the connecting structure, a second water channel provided in the stabilizing structure, and a water outlet provided on the inner side of the bottom beam and communicating with the second water channel;

[0013] One end of the first water channel is connected to the third water channel in the motor mobile phone, and the other end of the first water channel is connected to the center of the second water channel in the top beam. After the cleaning liquid is collected in the first water channel, it is sprayed out from the water outlet through the second water channel to rinse the surface of the implant.

[0014] Furthermore, the plurality of water outlets on the inner side surface of the bottom beam are evenly distributed in the polishing layer.

[0015] Furthermore, an inner arm is provided at the upper end of the support arm in the horizontal direction, the inner arm is inserted into the top beam, and the top beam and the inner arm are connected via a telescopic structure.

[0016] Furthermore, the polishing layer is a new type of composite coating, which takes nickel-titanium alloy as a matrix and embeds a predetermined amount of diamond particles. The polishing layer is attached to the forming needle by a sand embedding method.

[0017] The present invention also discloses a method for using the implant surface shaping needle according to claim 1, characterized in that the use of the shaping needle comprises the following steps:

[0018] S1: implant thread exposing the contaminated area of ​​the lower abutment surface of the implant;

[0019] S2: Replace the bur according to the diameter of the implant to make them match;

[0020] S3: Connect the needle and the motor handpiece through a connecting structure;

[0021] S4: The bur enters the oral cavity from the buccal or lingual / palatal side of the implant, and the implant is placed between the two support arms so that the polished layer fits the implant thread.

[0022] S5: The motor handpiece drives the needle to rotate through the connection structure, and the polishing layer contacts and rubs against the thread surface of the implant, performing three-dimensional cutting on the implant surface;

[0023] S6: After the cutting effect is achieved, remove the needle.

[0024] Furthermore, in step S6, after the needle is removed, the needle is sterilized by high-temperature and high-pressure steam.

[0025] Beneficial effects of the present invention:

[0026] The implant surface forming needle provided by the present invention is in a circumferential contact with the implant surface, and rotates under the drive of the motor mobile phone. The polishing layer and the implant surface are in contact and rubbed, which can easily achieve the removal of plaque at the implant neck thread and the polishing of the implant thread surface, creating a smooth surface that is not conducive to bacterial adsorption and eliminating peri-implantitis. In addition, the needle is driven by the motor mobile phone to achieve three-dimensional annular cutting of the implant surface, and the polishing efficiency is high, which is about 1.3 times that of ordinary diamond needles, reducing the loss of contaminated areas on the implant surface and reducing clinical working time. At the same time, compared with ordinary diamond needles, it can reduce the shedding of diamond particles during the grinding process, reduce the interference with the bony connection between the implant and the alveolar bone during the later healing process, and has better biocompatibility.

[0027] The outer dimensions of the bur of the present invention are adapted to the outer dimensions of the implant, and burs of different specifications can be selected according to clinical practice, or the distance between the two polishing layers can be adjusted by the telescopic structure in the stabilizing structure to adapt to various types of implants in clinical diagnosis and treatment. The symmetrical arrangement of the two support arms allows the bur to rotate smoothly and is not prone to shaking, thereby improving work efficiency while avoiding damage to the implant and surrounding soft and hard tissues, providing a more effective and safe way to treat peri-implantitis.

[0028] The present invention can achieve grinding and flushing at the same time through the cleaning structure, thereby preventing the local temperature of the implant from being too high to damage the activity of the implant surface coating and the activity of the bone, and preventing the ground debris from being accumulated locally, causing the problem of being difficult to clean.

[0029] The polishing layer of the present invention is a new composite coating with a nickel-titanium alloy as the matrix and diamond embedded. The nickel-titanium alloy used has shape memory function, and has the advantages of wear resistance, corrosion resistance, high damping and superelasticity. Its expansion rate is above 20%, and its corrosion resistance is better than the best medical stainless steel currently. It meets the application requirements of various engineering and medical fields and is a very excellent functional material. The nickel-titanium alloy embeds nano-diamonds in the Ni / Ni-P (chemical plating) method, and has good wettability for diamond particles, making it difficult to fall off, and prolonging the service life of the needle, which can be extended to about 1.5 times that of ordinary diamond needles.

DETAILED DESCRIPTION

[0040] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are only used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] The terms such as upper, lower, left, right, inside, outside, front end, rear end, head, tail, etc. in this application document are based on the positions or positions shown in the drawings. If the drawings are different, the corresponding positions may also change accordingly, so they cannot be understood as limiting the scope of protection.

[0042] In the present invention, the terms "install", "connected", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection or mutual communication, a direct connection or an indirect connection through an intermediate medium, the internal connection of two components, or the interaction relationship between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] This embodiment describes an implant surface shaping needle, which can easily remove plaque at the implant neck thread and polish the implant thread surface.

[0044] like Figure 1 , Figure 2 and Figure 8 As shown, the turning needle 1 includes a connecting structure 11, a stabilizing structure 12, and a polishing layer 13. The turning needle 1 is connected and fixed to a dental high-speed motor handpiece 8 through the top of the connecting structure 11. The bottom end of the connecting structure 11 is fixed to the top center of the stabilizing structure 12 to form the main support of the turning needle 1. The polishing layer 13 is arranged at the bottom of the stabilizing structure 12 to shape the surface of the implant 2.

[0045] In this embodiment, the connection structure 11 and the stabilizing structure 12 are integrally cast or welded in sections, and the connection structure 11 can be connected to the motor mobile phone 8 in a slot manner through the clamping shaft 85, or quickly connected with other quick-connect structures, so as to realize convenient and quick disassembly and assembly with the motor mobile phone 8. Preferably, the height of the connection structure 11 is 13.2-18.2 mm.

[0046] The stabilizing structure 12 is composed of a top beam 121, a support arm 122, and a bottom beam 123. The connecting structure 11 is fixed at the center of the top beam 121. Two support arms 122 are symmetrically fixed at both ends of the top beam 121. The bottom ends of the support arms 122 are connected to the bottom beam 123. The relative inner sides of the two bottom beams 123 are arranged in parallel and spaced at a predetermined interval, preferably 2.8 to 5.0 mm, which matches the diameter of the implant 2. The polishing layer 13 is arranged on the relative inner sides of the two bottom beams 123.

[0047] In one embodiment, the top beam 121, the support arm 122, and the bottom beam 123 are all square columns, and the top beam 121 and the bottom beam 123 are respectively connected vertically to the support arm 122. In order to match the external dimensions of the common implants 2 on the market, the stabilizing structure 12 can adopt the following dimensions: the thickness of the stabilizing structure 12 is 2 mm, the length of the top beam 121 is 9.3-10.8 mm, the height is 2 mm, the width of the support arm 122 is 2 mm, the height is 4.8 mm, and the length of the bottom beam 123 is 3 mm, and the height is 2 mm. This structural shape can improve the cutting efficiency, reduce the clinical working time, and avoid damage to the adjacent teeth 3 and the soft and hard tissues of the missing teeth during the cutting process.

[0048] Or in another embodiment, Figure 3 As shown, two support arms 122 are symmetrically installed at both ends of the top beam 121 at a predetermined angle ∠1, and the bottom beam 123 is a conical structure extending upward from the bottom end of the outer side surface at a predetermined cone angle ∠2. The predetermined cone angle ∠2 ensures that the inner side surface of the bottom beam 123 is perpendicular to the top beam 121. Preferably, the top width of the bottom beam 123 is 2mm, the width of the bottom end of the bottom beam 123 is 0, the height is 4.8mm, the predetermined angle ∠1 is 68-90°, the predetermined cone angle ∠2 is 0-22°, and the stable structure 12 is conducive to working in the sub-bone pocket around the implant 2, reducing the cleaning dead angle, and not hurting the surrounding tissue.

[0049] Preferably, the connecting structure 11 and the stabilizing structure 12 and the supporting arm 122 and the top beam 121 in the stabilizing structure 12 can be connected by joints. Figure 4As shown, the upper end of the support arm 122 is provided with an inner arm 126 in the horizontal direction, and the inner arm 126 is inserted into the top beam 121, so that the top beam 121 and the support arm 122 are connected in a nested manner. Preferably, the top beam 121 and the inner arm 126 are connected by a telescopic structure, and the telescopic structure can be composed of an adjustment hole 127 and a fixing bolt 128. The adjustment holes 127 are respectively provided on the top beam 121 and the inner arm 126. The number of the adjustment holes 127 on the inner arm 126 can be 2 or 3, or more than 2 can be provided according to actual conditions. The fixing bolt 128 cooperates with the adjustment hole 127 to fix the top beam 121 and the support arm 122. The fixing bolt 128 can be a latch, a lock pin or a screw. The stabilizing structure 12 is telescopically adjusted and fixed through the adjustment hole 127 and the fixing bolt 128, changing the distance between the left and right bottom beams 123 to match the sizes of different implants 2, so that the polishing layer 13 of the needle 1 is more closely fitted to the implant thread 22, thereby improving clinical work efficiency and reducing clinical inconvenience caused by inappropriate needle 1 size.

[0050] The polishing layer 13 is a new type of composite coating, which takes nickel-titanium alloy as a matrix and embeds a predetermined amount of diamond particles 7. Preferably, the diamond particles 7 are nano-diamond particles.

[0051] The novel composite coating can be prepared by electroplating process, for example, the process of electroplating preparation by using electroplating tank 6 is as follows:

[0052] 1. Before preparation, the nickel-titanium alloy substrate and the diamond particles 7 are pretreated;

[0053] Preferably, the nickel-titanium alloy substrate is pretreated before electroplating by using a mixed solution of HCl-H2SO4 to strengthen the bonding between the nickel-titanium alloy substrate and the coating, which can reduce the shedding of the diamond particles 7 while ensuring the hardness and wear resistance of the polishing layer 13, and avoid affecting the subsequent bone bonding and regeneration; the diamond particles 7 are pretreated by alkali washing to remove impurities and acid washing to roughen. Alkaline washing refers to boiling for 30 minutes in an alkali solution with a weight ratio of 1:4 between alkali solution and deionized water, and then rinsing with water to neutrality; acid washing and roughening refers to boiling for 30 minutes in an acid solution with a volume ratio of 1:1 between concentrated sulfuric acid (98wt.%) and water, and then rinsing with deionized water to neutrality, and air drying.

[0054] 2. Sand the needle 1;

[0055] This embodiment uses the buried sand method to sand the needle 1. The buried sand method can sand the two polishing layers 13 of the needle 1 at one time, and the sanding efficiency is high. Before sanding, the nickel-titanium alloy substrate of the needle 1 is inserted into the sand plating tank 61 filled with diamond particles 7 in the electroplating tank 6. The sand plating tank 61 is placed in an acidic electroplating solution 63 (such as a pH 4.0 electroplating solution). Figure 5As shown, the needle 1 is connected to the cathode end of the electroplating circuit, and the electroplating solution 63 is connected to the nickel anode 62 of the electroplating circuit placed in the sand plating tank 61. When sanding, the current density is first lowered (i.e., lower than the preset current density value), the stirring speed of the diamond particles 7 is 450rpm, and the temperature is 30°C. Slowly increase the current density to the preset value, such as the preset current density value is 0.5A / dm 2 ~2A / dm 2 The content of diamond particles 7 in the composite coating increases with the increase of cathode current density. Preferably, the current density is 1.5A / dm 2 When the amount of diamond particles 7 on the polishing layer 13 is increased and the diamond particles 7 are evenly distributed, and the matrix has a stronger grip on the diamond particles 7. After the sanding is maintained for 30 to 60 minutes, the needle 1 is taken out and the sand is unloaded in the electroplating solution 63 to obtain a needle product with even sand distribution.

[0056] When sanding, the entire turning needle 1 is tilted at a certain angle and then fixed. Preferably, the tilting angle is 45 degrees. At this time, half of the surface of the polishing layer 13 on the left and right sides of the turning needle 1 can be sanded at the same time, that is, the upper surface of the polishing layer 13 on one side and the lower surface of the polishing layer 13 on the other side are sanded at the same time. After the predetermined sanding time, the turning needle 1 is flipped 180° in the horizontal direction, and the other half of the surface of the polishing layer 13 on the left and right sides of the turning needle 1 is sanded.

[0057] 3. The sand-removed turning needle 1 is subjected to thickening plating, i.e., long-term deposition, to obtain a plating layer that can effectively hold the diamond particles 7. The thickening plating time is 4 to 5 hours, so that the thickness of the polishing layer 13 reaches 0.1 to 1 mm, and the content of diamond particles 7 in the polishing layer 13 is 4 g / L to 8 g / L, and a new composite plating layer that can effectively hold the diamond particles 7 is obtained.

[0058] In addition, the polishing layer 13 can also be made of high-toughness, fine-grained tungsten carbide material particles, or made of medical hard wear-resistant stainless steel.

[0059] The needle 1 of this embodiment is also provided with a cleaning structure, such as Figure 6 and Figure 7As shown, the cleaning structure is composed of a first water channel 112 provided at the center of the connecting structure 11, a second water channel 124 provided in the stabilizing structure 12, and a water outlet 125 provided on the surface of the polishing layer 13 on the inner side of the bottom beam 123 and communicating with the second water channel 124. One end of the first water channel 112 is communicated with the third water channel 83 in the motor mobile phone 8 mobile phone handle 82 or the external cleaning liquid 5 delivery channel, and the other end is communicated with the center of the second water channel 124 in the top beam 121. A plurality of water outlets 125 on the inner side of the bottom beam 123 are evenly distributed in the polishing layer 13. Preferably, the number of water outlets 125 is 4 to 10, or any number of more than 2 is set according to actual conditions. After the cleaning liquid 5 is collected in the first water channel 112, it is diverted to both sides at the center of the second water channel 124 in the top beam 121. After passing through the second water channel 124 of the support arms 122 on both sides, the cleaning liquid 5 is sprayed out from the water outlet 125 and acts on the surface of the implant 2, thereby removing and flushing the contaminated layer while grinding, preventing local temperature overheating, destroying the activity of the surface coating of the implant 2 and the alveolar bone 4, preventing debris accumulation, improving cleaning and grinding efficiency, and protecting the activity of the implant surface coating.

The mobile phone head 81 is provided with a clamping shaft 85, a turbine 86, and a bearing 87. The mobile phone handle 82 is provided with a third water channel 83 and an air pump pipeline 84. The clamping shaft 85 is vertically arranged in the mobile phone head 81. It is a hollow structure and is used for detachable connection with the connecting structure 11. The detachable connection method can be connected to the clamping shaft 85 slot through the connecting interface 111, or the connecting structure 11 is inserted into the clamping shaft 85 and clamped and connected through the clamping shaft 85, etc., which plays the role of fixing the titanium brush body and driving it to rotate clockwise or counterclockwise. The turbine 86 and the bearing 87 are located outside the clamping shaft 85. The turbine 86 is placed on the bearing 87 (the bearing 87 includes a fixed part and a rotating part, the fixed part is located outside and fixed to the mobile phone head 81, the rotating part is fixed to the clamping shaft 85, and the turbine 86 is fixed to the outside of the clamping shaft 85 to drive the clamping shaft 85 to rotate) and connected to the air pump channel 84. The air pump drives the turbine 86 to drive the clamping shaft 85 to rotate through the air pump channel 84, and the clamping shaft 85 drives the titanium brush body to rotate through the connecting structure 11. The turbine 86 can be set in an annular turbine cavity, and the air inlet of the turbine cavity is connected to the air pump pipeline 84. The exhaust port can be set below the turbine cavity, distributed, or can be discharged through the exhaust pipeline, or a water-gas separation baffle is set above the turbine 86 to isolate the water flow above from the intake air below. The opening of the third water channel 83 is placed at the top of the clamp shaft 85, and the opening is downward toward the central cavity of the clamp shaft 85. The upper part of the mobile phone head 81 forms a closed cavity to ensure the water pressure above. The opening of the third water channel 83 communicates with the first water channel 112 through the central cavity of the clamp shaft 85. The cleaning liquid 5 transported by the third water channel 83 flows into the first water channel 112 through the clamp shaft 85.

[0061] When performing dental implant surgery, Figure 8 As shown, the implant upper base 23 of the implant 2 is installed in the alveolar bone 4 through the implant thread 22 provided on the surface of the implant lower base 21. In order to eliminate the contaminated area on the surface of the implant lower base 21, the method of using the implant surface shaping needle of this embodiment is as follows:

[0066] S5: The motor handpiece 8 drives the needle 1 to rotate clockwise or counterclockwise through the connecting structure 11, and the polishing layer 13 contacts and rubs with the surface of the implant thread 22, thereby grinding and polishing the contaminated area of ​​the implant thread 22, thereby forming the surface of the implant 2; during the rotation of the needle 1, the motor handpiece 8 can also drive the needle 1 to be lifted up and down vertically, and to move forward, backward, left and right horizontally through the handpiece head 81, so as to achieve the purpose of three-dimensional cutting of 360° around the surface of the implant 2; during use, due to the size limitation of the needle 1, the upper base 23 of the implant and the soft and hard tissues of the surrounding adjacent teeth 3 will not be damaged;

[0067] S6: After the cutting effect is achieved, the implant shaping operation is completed, the needle 1 is removed, and the needle 1 is sterilized by high-temperature and high-pressure steam for reuse.
