[0029] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0030] The utility model provides Figures 1 to 3 As shown in , an improved inlay 400 bonding stick is intended to solve the shortcoming that the existing inlay 400 bonding stick cannot help determine the orientation of the inlay 400.

[0031] The improved inlay 400 bonding rod mainly includes: a handle 100, a rod neck 200 and a bonding head 300. The handle 100 has a distal end, and the handle 100 is used for medical staff to hold. The rod neck 200 is arranged on the distal end, and the bonding head 300 is arranged at the end of the rod neck 200 away from the handle 100. The bonding head 300 is used to bond and fix the inlay 400.

[0032] Specifically, the distal end is the end of the handle 100 facing the patient when the medical staff uses the instrument. The handle 100 is made of 304 stainless steel, 316 stainless steel or plastic with high rigidity, such as PPE. The existing auxiliary tools on the market have the disadvantage that the handle is not hard enough and it is inconvenient to add force to fix it. The doctor needs to change the instrument with his hands, which affects the accuracy and convenience of the doctor's clinical operation. And because the handle 100 is not easy to remove after being bonded to the inlay, in the practice of bonding the inlay in place, the removal of the bonding rod may cause the restoration to shift. Therefore, by increasing the rigidity of the handle 100, it is possible to avoid changing the instrument during the bonding process, which may cause the inlay to shift. The bonding joint 300 is made of resin material, and an adhesive layer is provided on the outer surface of the bonding joint 300. The adhesive layer can bond and fix the inlay 400 to the bonding joint 300.

[0033] The rod neck 200 includes: an inlay position identification part 220, which is used to identify the position of the oral cavity, and the position of the inlay 400 connected to the adhesive head 300 is the same as the position of the oral cavity identified by the inlay position identification part 220. In actual use, the position of the inlay 400 is first identified in advance, and the inlay 400 is adjusted so that the position of the inlay 400 coincides with the position of the inlay position identification part 220, and then the inlay 400 is bonded to the adhesive head 300 for fixation. When bonding the inlay 400 to the tooth, the medical staff can quickly identify the position of the inlay 400 according to the direction of the inlay position identification part 220.

[0034] At present, there are auxiliary tools available on the market, such as the invention patent with publication number: CN107080597A, which discloses a waterproof dental inlay 400 bonding stick, which includes a bonding stick body, bonding glue and a sheath; the bonding stick body is composed of a bonding stick head, a neck and a handle 100; the bonding glue is wrapped around the outer periphery of the bonding stick head by its own viscosity; and the exposed part of the bonding glue is used to bond the inlay 400. However, the existing inlay 400 bonding stick has no auxiliary markings, and the position of the inlay 400 cannot be simply and clearly determined. The doctor can only rely on visual inspection of the tooth surface morphology to identify the position of the inlay 400, which affects the accuracy and convenience of the operation.

[0035] The utility model provides an inlay position identification portion 220 at the neck 200 of the inlay 400 bonding rod, and when the inlay 400 is bonded to the bonding head 300, the position of the inlay 400 is identified in advance, and the inlay 400 is adjusted so that the position of the inlay 400 matches the position of the inlay position identification portion 220, and then the inlay 400 is bonded to the bonding head 300 for fixation. When bonding the inlay 400 to the tooth, the medical staff can quickly identify the position of the inlay 400 according to the direction of the inlay position identification portion 220, which is beneficial to improving the bonding accuracy of the inlay 400 to the tooth and accelerating the bonding efficiency of the inlay 400.

[0036] In some embodiments, Figures 1 to 3 As shown in the figure, the inlay orientation identification part 220 includes: a plurality of letter identification parts 221, and the plurality of letter identification parts 221 are arranged at intervals on the outer surface of the rod neck 200, and the plurality of letter identification parts 221 are respectively facing the mesial direction, distal direction, buccal direction, lingual direction and forward direction of the patient's oral cavity.

[0037] In some embodiments, Figures 1 to 3 As shown in , the plurality of letter identification parts 221 respectively include: an "M" identification part, a "D" identification part, a "B" identification part, an "L" identification part and a "P" identification part, and are respectively protruding or concave in the inlay orientation identification part 220;

[0038] The "M" marking portion, the "D" marking portion, the "B" marking portion, the "L" marking portion and the "P" marking portion are respectively facing the mesial direction, distal direction, buccal direction, lingual direction and forward direction of the patient's mouth.

[0039] Specifically, the "M" logo, the "D" logo, the "B" logo, the "L" logo and the "P" logo are the following English abbreviations: MESIAL: The tooth surface facing the midline (the line in the middle of the dental arch) is the mesial surface; DISTAL: (The antonym of mesial.) The tooth surface facing the back of the dental arch is the distal surface; BUCCAL: The tooth surface of the back teeth facing the cheek; LINGUAL: refers to the tooth surface facing the tongue; PROCLINE: Proclination refers to the direction of moving the incisal edge of the front teeth toward the labial direction. Medical staff are more sensitive to the above English words and can quickly identify the direction of the inlay 400 through the above abbreviations.

[0040] In some embodiments, Figures 1 to 3 As shown in , the rod neck 200 includes: a rod neck body 210, the middle part of the rod neck body 210 is bent away from the axis of the handle 100 to form an inlay orientation identification part 220, and the two ends of the rod neck body 210 are respectively connected to the handle 100 and the adhesive head 300.

[0041] Specifically, the rod neck body 210 is in a "V" shape. During actual use, the inlay position marking portion 220 faces upward, which is convenient for medical staff to observe. Moreover, since the inlay position marking portion 220 protrudes upward, it is not easy to block the medical staff's line of sight of the patient's oral cavity.

[0042] In some embodiments, Figures 1 to 3 As shown in FIG. 1 , the axis of the handle 100 is located between the inlay position identification portion 220 and the adhesive head 300 .

[0043] During actual use, the adhesive head 300 faces downward, and when the handle 100 is in a horizontal state, the height of the adhesive head 300 is slightly lower than the axis of the handle 100, so that the inlay 400 fixed on the adhesive head 300 is away from the handle 100. In actual operation, the handle 100 is not easy to block the line of sight of the inlay 400.

[0044] In some embodiments, Figures 1 to 3 As shown in , the bonding head 300 is spherical, and the radius of the bonding head 300 is greater than the radius of the rod neck body 210. In actual operation, the rod neck body 210 is not easy to block the sight of the inlay 400.

[0045] In some embodiments, Figures 1 to 3 As shown in FIG. 1 , the outer diameter of the handle 100 gradually decreases toward the distal end.

[0046] Specifically, the above structure can make the center of gravity of the handle 100 slightly away from the distal end, that is, the center of gravity is close to the hand of the medical staff, so that the medical staff will not be too tired when holding the handle 100 for a long time, and in actual operation, the distal end of the handle 100 is not easy to block the line of sight of the inlay 400.

[0047] In some embodiments, Figures 1 to 3 As shown in , the ratio of the length of the rod neck body 210 on the axis of the handle 100 to the length of the handle 100 is between 0.1 and 0.3. This ratio meets the actual use requirements and does not cause the handle 100 to be too long or too short, causing medical staff to be too tired when holding the handle 100 for a long time.

[0048] In some embodiments, Figures 1 to 3 As shown in , the bonding head 300 is detachably connected to the rod neck body 210 , and the bonding head 300 has specifications of various radii of different sizes.

[0049] In actual use, different adhesive heads 300 may be replaced according to the shape of the inlay 400 to make the connection between the adhesive head 300 and the inlay 400 more stable.

[0050] In some embodiments, Figures 1 to 3 As shown in , the inlay position identification portion 220 also includes: a plurality of color identification blocks 222, the colors of the plurality of color identification blocks 222 are different, the plurality of color identification blocks 222 are respectively facing the mesial direction, distal direction, buccal direction, lingual direction and forward direction of the patient's oral cavity, and the plurality of color identification blocks 222 cover the outer surface of the inlay position identification portion 220.

[0051] Since the space in the oral cavity is small, blind spots in lighting are easily generated. Compared with text, medical staff can more easily identify the specific position of the inlay 400 through a plurality of color-coded blocks 222. When bonding the inlay 400 to the tooth, the medical staff can quickly identify the position of the inlay 400 based on the color-coded blocks 222.

[0052] In summary, an improved inlay bonding rod is provided, which includes a handle, a rod neck and a bonding head. The handle is used for medical staff to hold, and the handle, the rod neck and the bonding head are connected in sequence. The bonding head is used to bond and fix the inlay. The rod neck includes an inlay orientation identification part for identifying the orientation of the oral cavity. The orientation of the inlay connected to the bonding head is the same as the orientation of the oral cavity identified by the inlay orientation identification part. The utility model sets an inlay orientation identification part at the rod neck position of the inlay bonding rod. When bonding the inlay to the bonding head, the orientation of the inlay is identified in advance, and the inlay is adjusted so that the orientation of the inlay matches the orientation of the inlay orientation identification part before bonding the inlay to the bonding head for fixing. When bonding the inlay to the tooth, the medical staff can quickly identify the orientation of the inlay according to the direction of the inlay orientation identification part, which is beneficial to improving the accuracy of bonding the inlay to the tooth and accelerating the efficiency of bonding the inlay.

[0053] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
