[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model proposes an auxiliary device for locating labial surface landmark lines, comprising a canine line marking assembly and a smile line marking assembly. The canine line marking assembly includes two canine line marking modules and a bisector of the intermaxillary distance module. In use, the second insertion surface of the bisector of the intermaxillary distance module is inserted into the wax rim, and the two canine line marking modules are inserted into the bisector of the intermaxillary distance module through a first slot. The two canine line marking modules are then inserted to align with the positions of the two canines on the wax rim, thus marking the canine line. The smile line marking assembly includes at least one lip line marking module and a midline marking module. The midline marking module is inserted into the wax rim through a fourth insertion surface to mark the midline, and the lip line marking module is inserted into the midline marking module through a second slot.

Detailed Implementation

[0029] The following is combined with Figures 1 to 7 This utility model will be described in detail.

[0030] A device for assisting in the positioning of lip line markers includes a canine line marking assembly 10, which includes two canine line marking modules 20 and a bisector of the intermaxillary distance module 30. Each canine line marking module 20 has a first insertion surface 201 for inserting a wax rim 40 and a first slot 202. The bisector of the intermaxillary distance module 30 is inserted into and adapted to the first slot 202 and has a second insertion surface 301 for inserting the wax rim 40. A smile line marking assembly 50 includes at least one lip line marking module 60 and a midline marking module 70. The top and / or bottom surfaces of the lip line marking module 60 form a positioning surface for contact with the lips. One side of the lip line marking module 60 has a third insertion surface 601 for inserting the wax rim 40 and a second slot 602 facing the wax rim 40. One side of the midline marking module 70 has a fourth insertion surface 701 for inserting the wax rim 40, and the other side is inserted into and adapted to the second slot 602.

[0031] After the location of the labial surface marker line in a complete denture is determined within the occlusal rim, it must be marked. At least the positions of the midline, canine line (corner of the mouth line), and smile line need to be indicated. The midline is generally the facial midline, the canine line is generally located at the edges of the patient's nasal alae on both sides, and the smile line is the position of the upper and lower lips when the patient smiles, including the lip height line and lip depth line. This invention provides an auxiliary device for positioning the labial surface marker line, including a midline marking module 70 that can determine and mark the midline position, a canine line marking component 10, and a smile line marking component 50 that further mark the canine line and smile line based on the determined midline, thereby improving the accuracy of the marking. When marking the canine line and smile line, the canine line marking module 20 and the lip line marking module 60 complete the marking through the cooperation of interlocking modules. This is equivalent to using the intermaxillary distance module 30 and the midline marking module 70 as auxiliary tracks for movement, preventing the canine line marking module 20 and the lip line marking module 60 from tilting or deviating due to patient tension or shaking by medical staff during the marking of the canine line and smile line.

[0032] In this embodiment, the bisector of the intermaxillary distance module 30 is provided with a marking position that can be aligned with the facial midline. The marking position is a groove 302, which ensures, as far as possible, that the two canine line marking modules 20 are symmetrically distributed relative to the facial midline when marking the canine lines. Specifically, as shown... Figure 3 As shown, when marking the midline, simply insert the fourth insertion surface 701 of the midline marking module 70 into the wax rim 40, referring to the facial midline. When marking the canine line, as... Figure 1 As shown, first insert the second insertion surface 301 of the occlusal spacing module 30 into the wax rim 40. At this time, the groove 302 is aligned with the facial midline. Then, the two canine line marking modules 20 are roughly spliced ​​with the occlusal spacing module 30 through the first slot 202. Next, adjust the canine line marking modules 20 to the appropriate position according to different patients' conditions. Finally, insert each first insertion surface 201 into the wax rim 40 to complete the canine line marking. At this time, the two canine line marking modules 20 and the occlusal spacing module 30 are completely engaged. When marking the smile line, as... Figure 4 As shown, first, the fourth insertion surface 701 of the centerline marking module 70 is inserted into the wax rim 40. Then, the second slot 602 portion of the lip line marking module 60 is engaged with the centerline marking module 70. The lip line marking module 60 is controlled to move along the centerline marking module 70 until the positioning surface contacts the upper lip. Then, the third insertion surface 601 of the lip line marking module 60 is inserted into the wax rim 40 along the engagement direction of the second slot 602, thus obtaining the marking of the lip height line. Then, the lip line marking module 60 is removed, or another lip line marking module 60 is taken, and the marking of the lip low line is completed according to the steps for marking the lip height line. In some embodiments, the marking of the centerline can be completed together with the marking of the smile line, without the need for separate marking.

[0033] This design avoids the use of sharp instruments, preventing accidental injury to patients. Furthermore, the multi-module combination provides greater stability during operation compared to a single module. For example, when marking canine lines, two canine line marking modules 20 are inserted simultaneously into the wax rim 40, and the two modules are symmetrical. Compared to marking twice with a single module, the cooperation between the two canine line marking modules 20 and the intermaxillary distance bisector module 30 in this embodiment achieves a coordinate system positioning effect with less error. When marking smile lines, as the lip line marking module 60 moves to the appropriate position, it inserts into the wax rim 40 along the surface of the midline marking module 70. Since the midline marking module 70 remains fixed to the wax rim 40, the third insertion surface 601 maintains a relatively stable movement path during insertion into the wax rim 40, resulting in a smaller marking error.

[0034] In this embodiment, the openings of the first slot 202 and the second slot 602 gradually decrease along their insertion direction, making alignment simpler and reducing the likelihood of misalignment during insertion. Simultaneously, the first slot 202 and the second slot 602 better engage the bisector jaw spacing module 30 and the centerline marking module 70, creating a tighter contact and improving connection stability. Gaskets are fixed inside the first slot 202 and the second slot 602 to reduce friction between modules, thereby extending service life and further improving connection stability.

[0035] In this embodiment, the cross-sections of the first insertion surface 201, the third insertion surface 601, and the fourth insertion surface 701 gradually decrease in the direction close to the wax dam 40, that is, the smaller cross-sections first contact the wax dam 40, which facilitates insertion into the wax dam 40 to complete the positioning mark; the end faces of the first insertion surface 201, the second insertion surface 301, the third insertion surface 601, and the fourth insertion surface 701 near the wax dam 40 are formed with arc surfaces, that is, the surface moving towards the patient's cavity is an arc surface, to avoid sharp parts accidentally injuring the patient.

[0036] In this embodiment, the occlusal spacing module 30 is provided with several first mating slots 303 adapted to the first slot 202, and the midline marking module 70 is provided with several second mating slots 702 adapted to the second slot 602. The first mating slots 303 and second mating slots 702 are equidistantly distributed, and each first mating slot 303 is symmetrically distributed on both sides of the groove 302. When the canine line marking module 20 and the lip line marking module 60 move to the appropriate position, the first slot 202 engages with the first mating slot 303, and the second slot 602 engages with the second mating slot 702. This further improves the stability of the canine line marking module 20 and the lip line marking module 60 when inserted into the wax embankment 40 during the engagement process, ensuring that the canine line marking module 20 and the lip line marking module 60 maintain their marking path movement and reducing marking errors. The openings and spacing of each first mating slot 303 and the second mating slot 702 are small, resulting in negligible errors.

[0037] In this embodiment, the canine floss marking component 10 and the smile line marking component 50 are made of metal. Before marking, the first insertion surface 201, the third insertion surface 601, and the fourth insertion surface 701 are heated so that when they come into contact with the wax rim 40, the heat softens the wax rim 40, making it easier to leave a mark. The heated temperature is only enough to slightly soften the wax rim 40 to avoid accidentally injuring the patient due to excessive heat. In some embodiments, the canine floss marking component 10 and the smile line marking component 50 can be directly inserted into the wax rim 40 to complete the marking. The canine floss marking component 10 and the smile line marking component 50 can also be made of resin, which has a long service life and low manufacturing cost.

[0038] In this embodiment, as Figure 6 and Figure 7 As shown, the canine line marking module 20 includes a first engaging portion 203 and a first operating portion 204. The first engaging portion 203 has a first insertion surface 201 and a first slot 202. The width of the first operating portion 204 is greater than the width of the first engaging portion 203 for ease of use by medical personnel. The occlusal spacing dividing module 30 has a groove 302 on one side and several first connecting grooves 303 on the other side. The opening directions of the groove 302 and the first connecting grooves 303 are opposite. The lip line marking module 60 includes a second engaging portion 603 and a second operating portion 604. The second engaging portion 603 has a third insertion surface 601 and a second slot 602. The width of the second operating portion 604 is greater than the width of the second engaging portion 603 for ease of use by medical personnel. The bottom surface and / or bottom surface of the second operating portion 604 form a positioning surface. In some embodiments, the canine line marking module 20 and the lip line marking module 60 can be used interchangeably. However, the intermaxillary distance bisector module 30 and the midline marking module 70 cannot be used interchangeably. The length of the midline marking module 70 needs to ensure that it does not touch the lips when marking the smile line. In this embodiment, the length of the first operating part 204 is longer than the length of the second operating part 604, and the length of the midline marking module 70 is shorter than the length of the intermaxillary distance bisector module 30.

[0039] The working principle of the auxiliary lip surface marker line positioning device proposed in this utility model is as follows:

[0040] When marking the center line, such as Figure 3 As shown, the fourth insertion surface 701 is heated, and then the fourth insertion surface 701 of the centerline marking module 70 is inserted into the wax rim 40 according to the centerline position of the face. After removing the centerline marking module 70, a centerline mark 80 will be left on the wax rim 40, as shown. Figure 5 As shown.

[0041] When marking canine lines, first roughly assemble the two canine line marking modules 20 with the intermaxillary distance bisector module 30, making them perpendicular. Then, bring the canine line marking assembly 10 close to the wax rim 40. Adjust the assembly position again to reduce errors according to different patients' conditions. Then, snap the canine line marking module 20 and the intermaxillary distance bisector module 30 together. Next, heat the first insertion surface 201. After aligning the groove 302 of the intermaxillary distance bisector module 30 with the midline, insert each first insertion surface 201 perpendicularly into the wax rim 40 along the surface of the intermaxillary distance bisector module 30. After removing the canine line marking module 20 and the intermaxillary distance bisector module 30 in sequence, the desired result can be obtained. Figure 2 The canine line is marked 90.

[0042] When marking the smile line, first insert the fourth insertion surface 701 of the center line marking module 70 into the wax rim 40. Then, engage the second slot 602 of the lip line marking module 60 with the center line marking module 70. At this time, the lip line marking module 60 is perpendicular to the center line marking module 70, and the second slot 602 can move along the center line marking module 70. When it moves to the point where the positioning surface contacts the upper lip, insert the third insertion surface 601 of the lip line marking module 60 perpendicularly to the wax rim 40 along the engaging direction of the second slot 602 to obtain the lip height line mark 100. Then repeat the steps of marking the lip height line to obtain the lip low line mark 110. Figure 5 As shown.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
