[0002] Implant dentures are made by implanting an implant (artificial tooth root) into the alveolar bone in the edentulous area of ​​the mouth. After the implant takes root, a restoration is made on its upper end to complete the restoration of the implant denture. It refers to a method of tooth restoration that uses the lower structure implanted in the bone tissue as a basis to support and retain the upper dental restoration. It is also one of the repair methods that people are increasingly using after tooth loss.

[0003] A primary condition for the success of dental implants is to ensure that there is sufficient alveolar bone in the implant area. Bone powder needs to be filled inside the alveolar using a bone powder filler. It can significantly improve the patient's chewing function and feel comfortable like real teeth. Many difficult clinical cases that are difficult to solve with conventional dentures can achieve satisfactory results through implant dentures.

[0004] Although existing bone powder fillers can fill the tooth sockets with bone powder, the distribution of the bone powder is not uniform enough, and medical staff often need to manually smooth the bone powder using instruments such as tweezers. However, due to the different shapes of different tooth sockets, tweezers and other instruments are easily blocked by the notches of the tooth sockets, making it difficult to quickly smooth the bone powder, reducing the work efficiency of medical staff.

Therefore, they should not be understood as limiting the present invention.

[0020] In addition, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. In the description of the present invention, "plurality" means more than two, unless otherwise specifically defined.

[0021] like Figure 1-Figure 5 As shown, the present invention provides a bone powder filler for oral restoration and implantation, comprising a filling tube 10 , a push rod 20 , a fixing ring 30 , an annular airbag 40 and a control component 50 .

[0022] A limiting ring 11 is fixedly installed at the bottom of the inner wall of the filling tube 10 . The bottom of the limiting ring 11 is flush with the bottom of the filling tube 10 . A discharge hole 12 is opened in the middle of the limiting ring 11 , and a plug 13 is provided at the discharge hole 12 .

[0023] The push rod 20 is disposed in the filling tube 10 and is in sliding contact with the inner wall of the filling tube 10. A blocking column 21 adapted to the discharge hole 12 is fixedly mounted at the bottom of the push rod 20, and the bottom of the blocking column 21 is flush with the bottom of the filling tube 10.

[0024] The fixing ring 30 is sleeved on the bottom of the outer wall of the filling tube 10 and is integrally formed with the filling tube 10. A plurality of guide holes 31 extending inwardly in the transverse direction are formed on the outer circumference of the fixing ring 30. The plurality of guide holes 31 are arranged at intervals along the circumferential direction.

[0025] An annular airbag 40 is sleeved onto the outer circumference of the retaining ring 30. Its two sides are fixedly connected to the upper and lower sides of the retaining ring 30, respectively. A plurality of guide rods 41 are disposed within the annular airbag 40, corresponding one-to-one with the plurality of guide holes 31. The first ends of the guide rods 41 are fixedly connected to the inner wall of the lower side of the annular airbag 40, while the second ends of the guide rods 41 are in sliding contact with the inner walls of the guide holes 31.

[0026] The control assembly 50 is used to inflate or suction the annular airbag 40. When the control assembly 50 inflates the annular airbag 40, the annular airbag 40 successively passes through an expansion phase and an expansion phase. When the annular airbag 40 is in the expansion phase, the annular airbag 40 never contacts the notch of the alveolar socket. That is, when the annular airbag 40 is in a fully expanded state, its size is still smaller than the notch of the alveolar socket. When the control assembly 50 continues to inflate the annular airbag 40, the annular airbag 40 transitions from the expansion phase to the expansion phase. Because the annular airbag 40 is elastic, its material is stretched during the expansion phase. Due to the guiding effect of the guide rod 41, the bottom of the annular airbag 40 and the bottom of the filling tube 10 are now on the same horizontal plane.

[0027] In the initial state, the annular airbag 40 is in a contracted state, and the push rod 20 is not inserted into the filling tube 10 .

[0028] The specific use process of the present invention is: In the first step, the medical staff adds bone powder into the filling tube 10 and inserts the push rod 20 into the filling tube 10 .

[0029] In the second step, the medical staff removes the plug 13, puts the filling tube 10 into the patient's mouth, moves it to the notch of the alveolar socket, presses the push rod 20 downward, and the bone powder in the filling tube 10 will be discharged from the discharge hole 12 and fall into the alveolar socket, thereby filling the alveolar socket until the bone powder is filled to the notch of the alveolar socket.

[0030] In the third step, the medical staff removes the filling tube 10 from the patient's mouth and continues to press the push rod 20 to discharge the remaining bone powder in the filling tube 10 into the bone powder box. At this time, the plugging head 13 is inserted into the discharge hole 12.

[0031] In the fourth step, the medical professional inserts the bottom of the filling tube 10 into the notch of the alveolar socket and, through the control assembly 50, inflates the annular airbag 40 until it reaches the expanded stage. Due to its elasticity, the annular airbag 40 will fit perfectly within the notch of the alveolar socket, regardless of its shape. Guided by the guide rod 41, the bottoms of the annular airbag 40, the limiting ring 11, the blocking column 21, and the bottom of the filling tube 10 are now aligned at the same level.

[0032] In the fifth step, the medical staff gently presses down the filling tube 10. Since the bottom of the annular airbag 40, the bottom of the limiting ring 11, the bottom of the blocking column 21 and the bottom of the filling tube 10 are at the same horizontal plane, and the annular airbag 40 fits perfectly with the notch of the tooth socket, the filled bone powder can be quickly smoothed, improving the work efficiency of the medical staff.

[0033] Existing bone powder fillers cannot adapt to the shapes of different tooth socket notches, and therefore cannot quickly smooth out the filled bone powder. Using tweezers or other tools to smooth out the bone powder takes a long time and the smoothing effect is not ideal. The present invention utilizes the elasticity of the annular airbag 40 and the limiting function of the guide rod 41, so that the annular airbag 40 fits perfectly with the notch of the tooth socket, and the bottom of the annular airbag 40, the bottom of the limiting ring 11, the bottom of the blocking column 21, and the bottom of the filling tube 10 are on the same horizontal plane, so that the filled bone powder can be quickly smoothed out, improving the work efficiency of medical staff.

[0034] In one embodiment, a pressure ring 23 is fixedly installed on the top of the push rod 20 , and finger rings 16 are respectively provided on both sides of the filling tube 10 . The finger rings 16 are fixedly connected to the filling tube 10 via a transverse plate 18 .

[0035] Medical personnel control the movement of the push rod 20 through the pressure ring 23 and hold the filling tube 10 through the finger ring 16 to further facilitate operation.

[0036] In one embodiment, two locking assemblies 60 are further included. The two locking assemblies 60 are respectively disposed on both sides of the filling tube 10 .

[0037] The locking assembly 60 includes a guide plate 61, a fixed block 62, a locking rod 63 and a second spring 64. The guide plate 61 is arranged longitudinally, the first end of the guide plate 61 is fixedly connected to the pressure ring 23, the second end of the guide plate 61 passes through the transverse plate 18 and extends downward, and the guide plate 61 is slidably connected to the transverse plate 18. A locking hole 65 is provided on the guide plate 61. The fixed block 62 is fixedly mounted on the transverse plate 18, and a guide groove is provided on the end face of the fixed block 62. The locking rod 63 is arranged transversely in the guide groove and is in sliding contact with the inner wall of the guide groove. The locking rod 63 is adapted to the locking hole 65. The second spring 64 is sleeved on the locking rod 63, the first end of the second spring 64 is fixedly connected to the fixed block 62, and the second end of the second spring 64 is fixedly connected to the locking rod 63. The second spring 64 makes the locking rod 63 tend to approach the guide plate 61.

[0038] In the initial state, the locking hole 65 is located above the locking rod 63 .

[0039] When the medical staff presses the push rod 20 to discharge the remaining bone powder in the filling tube 10 into the bone powder box, the locking hole 65 is aligned with the locking rod 63. Under the action of the second spring 64, the locking rod 63 will be partially inserted into the locking hole 65. At this time, the plugging head 13 is just inserted into the discharge hole 12, and the bottom of the plugging column 21 remains flush with the bottom of the limiting ring 11.

[0040] This design allows the locking rod 63 to automatically fix the position of the push rod 20 when the medical staff discharges the remaining bone powder in the filling tube 10 into the bone powder box. The present invention is in a locked state. At this time, the bottom of the blocking column 21 remains flush with the bottom of the limiting ring 11 to prevent the push rod 20 and the blocking column 21 from loosening, making it easier to smooth the bone powder later.

[0041] After the use of the present invention is finished, the medical staff can pull the locking rod 63 outwards so that the locking rod 63 leaves the locking hole.

[0042] In one embodiment, the locking assembly 60 further includes a universal ball 66 , which is universally connected to the outer end surface of the locking rod 63 and is in rolling contact with the guide plate 61 .

[0043] When the medical staff presses the push rod 20, the universal ball 66 will roll on the guide plate 61, thereby reducing the friction between the locking rod 63 and the guide plate 61, making the use of the present invention smoother.

[0044] In one embodiment, a downwardly extending annular groove 14 is formed on the top of the filling tube 10 , and the annular groove 14 is connected to the interior of the annular airbag 40 through a plurality of connecting holes 15 .

[0045] The control assembly 50 includes a movable tube 51 and a first spring 52. The movable tube 51 is longitudinally disposed within the annular groove 14. The movable tube 51 is in sliding contact with the inner wall of the annular groove 14, and a sealing ring is provided between the movable tube 51 and the inner wall. The first spring 52 is disposed within the annular groove 14. The first end of the first spring 52 is fixedly connected to the bottom of the annular groove 14, and the second end of the first spring 52 is fixedly connected to the bottom of the movable tube 51.

[0046] In the initial state, the first spring 52 is in a natural state. The first spring 52 pushes the movable tube 51 upward for a distance. Under the action of air pressure, the annular airbag 40 is in a contracted state.

[0047] When the control component 50 inflates the annular airbag 40, the medical staff presses the movable tube 51 downward. At this time, the first spring 52 is compressed, and the gas in the annular groove 14 enters the annular airbag 40 through the connecting hole 15, thereby inflating the annular airbag 40.

[0048] When the present invention is finished using, the medical staff releases the movable tube 51, and under the action of the first spring 52, the movable tube 51 moves upward, and the present invention will automatically return to its initial state.

[0049] In one embodiment, the upper portion of the push rod 20 has a threaded section 22 .

[0050] The control assembly 50 further includes a threaded sleeve 53 . The threaded sleeve 53 is sleeved on the threaded section 22 and threadedly connected to the threaded section 22 . The bottom of the threaded sleeve 53 contacts the top of the movable tube 51 .

[0051] When the control component 50 inflates the annular airbag 40, the medical staff holds the filling tube 10 with the first hand and rotates the threaded sleeve 53 with the second hand. The threaded sleeve 53 moves downward and contacts the movable tube 51. The threaded sleeve 53 continues to be rotated, and the threaded sleeve 53 presses the movable tube 51 downward. When the annular airbag 40 expands to an appropriate degree, the medical staff can release the second hand and then gently press the filling tube 10 downward to smooth the bone powder.

[0052] When the present invention is finished using, the medical staff rotates the threaded sleeve 53 in the reverse direction, and under the action of the first spring 52, the movable tube 51 moves upward, and the present invention will automatically return to its initial state.

[0053] The design of the threaded sleeve 53 allows the medical staff to release the second hand when the annular airbag 40 is expanded to a suitable degree, so there is no need to keep pressing the movable tube 51, which further facilitates the operation of the medical staff.

[0054] In one embodiment, the guide rod 41 is adapted to the guide hole 31 , and the guide hole 31 is communicated with the annular groove 14 .

[0055] In this way, when the movable tube 51 moves downward, on the one hand, the gas in the annular groove 14 will enter the annular airbag 40 through the connecting hole 15, inflating the annular airbag 40; on the other hand, the gas in the annular groove 14 will enter the guide hole 31, pushing the guide rod 41 outward, so that the bottom of the annular airbag 40 and the bottom of the filling tube 10 are better at the same horizontal plane.

[0056] In one embodiment, a guide cavity 17 extending downward and having a gradually decreasing diameter is formed on the top of the limiting ring 11, and the guide cavity 17 is connected to the discharge hole 12. The design of the guide cavity 17 can promote the discharge of bone powder from the discharge hole 12 and avoid the accumulation of bone powder.

[0057] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as illustrative and non-restrictive in all respects.
