Description

Veneer bonding guide plate, auxiliary positioning plate and pressing tool for veneer bonding

Technical Field

The invention belongs to the field of medical devices, and in particular relates to a veneer bonding guide plate, an auxiliary positioning plate and a veneer bonding pressing tool.

Background technique

Veneers are thin restorations that are attached to the surface of teeth to repair and improve them. After years of clinical experience in veneer bonding by dentists, the main challenges facing veneer bonding are as follows:

During the bonding process of veneers, the position of each tooth corresponding to the veneer needs to be accurately determined. The teeth for ultra-thin non-abrasive veneers have no seating path and no shoulder. It is not easy to find the exact position, and a deviation in the position of one tooth will affect the position of other teeth. During the bonding process of half-mouth veneers, if all veneers cannot be retained as a whole, the doctor will need to repeatedly confirm whether each veneer is in place, which is not accurate and time-consuming and labor-intensive.

In recent years, some people in the industry have proposed a guide plate for veneer bonding. This guide plate includes an arc-shaped guide plate body with multiple adjustment rods inserted on the guide plate body. The adjustment rod has a veneer seating groove at one end close to the tooth. The shape and size of the veneer seating groove match the veneer. When using it, first install the veneer on the veneer seating groove, then put the guide plate on the tooth, push the adjustment rod to make the veneer on the veneer seating groove fit tightly with the tooth, and remove the guide plate after light curing. Although this guide plate can improve the efficiency and accuracy of veneer bonding to a certain extent, it still has the following problems:

1) When bonding multiple veneers, the doctor needs to operate the adjustment rods one by one, which is not convenient;

2) The guide plate lacks horizontal positioning of the veneers, and the doctor needs to correct the veneers one by one.

In the description of the present invention, it should be understood that the term "lingual side" refers to the side close to the tongue for teeth and veneers, and refers to the side close to the tongue when worn on the teeth for veneer bonding guides and auxiliary positioning plates; the term "labial side" refers to the side close to the lips for teeth and veneers, and refers to the side close to the lips when worn on the teeth for veneer bonding guides and auxiliary positioning plates; the term "crown end" refers to the end close to the crown of the tooth when worn on the teeth for veneer bonding guides, auxiliary positioning plates and veneers; the term "root end" refers to the end close to the root of the tooth when worn on the teeth for veneer bonding guides, auxiliary positioning plates and veneers.

In conjunction with the XYZ coordinate axes in FIG2 , the “lingual side”, “labial side”, “crown end” and “root end” are further explained: “lingual side” is the negative side of the X axis, “labial side” is the positive side of the X axis, “crown end” is the negative end of the Z axis, and “root end” is the positive end of the Z axis. In addition, the term “left and right” in the present invention refers to the Y axis direction in FIG2 .

In the description of the present invention, it is necessary to understand that the terms "up and down", "left and right", and "front and back" are only used to facilitate the description of the present invention and simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

The present invention will be further described below in conjunction with the accompanying drawings.

Example 1

Please refer to Figures 1, 2, 4 and 5. A veneer bonding guide plate is an integrally formed structure that can be produced by injection molding or 3D printing, including a guide plate body. The guide plate body includes a positioning portion 101, a lingual portion 102 arranged on the lingual side of the positioning portion 101, and a labial portion 103 arranged on the labial side of the positioning portion 101. The positioning portion 101 includes a plurality of continuously arranged positioning grooves 1011. The positioning grooves 1011 position the teeth and the cutting ends of the veneer, and position the horizontal installation position and vertical installation position of the veneer relative to the teeth.

It can be understood that in the above technical scheme, this embodiment realizes positioning with the teeth by positioning the tooth socket 1011, thereby assisting the doctor to find the accurate position of the teeth corresponding to the veneer, and also realizes positioning of the veneer installation position by positioning the tooth socket 1011, making the veneer operation simpler and improving the success rate of the veneer.

Continuing to refer to FIG. 1 , the positioning portion 101 also includes a guide plate positioning protrusion 1012 disposed between adjacent positioning tooth grooves 1011 . The guide plate positioning protrusion 1012 connects the lingual portion 102 and the labial portion 103 . Its shape and size match the triangular gap at the incisal end of the tooth and is used to fit into the triangular gap at the incisal end of the tooth.

Among them, the structure of the tooth incisal tip and the triangular gap between the tooth incisal tips is shown in Figure 3.

The positioning alveolar 1011 is fitted with the whole formed by the tooth incisor, the veneer incisor and the adhesive filled therebetween. Specifically, the positioning alveolar 1011 includes an alveolar lingual side wall 10111 close to the lingual side, an alveolar labial side wall 10112 close to the labial side and two alveolar side walls 10113 arranged opposite to and connected between the alveolar lingual side wall 10111 and the alveolar labial side wall 10112. The alveolar lingual side wall 10111 abuts against the lingual surface of the tooth incisor, and the alveolar labial side wall 10111 abuts against the labial surface of the veneer incisor, which is equivalent to the labial side part 103 abutting against the labial surface of the veneer incisor, so that the vertical distance of the veneer incisor relative to the labial surface of the tooth can be limited. The two alveolar side walls 10113 adjacent to each other on the two adjacent positioning alveolar 1011 form a guide plate positioning protrusion 1012, and the left and right sides of the tooth incisor and the left and right sides of the veneer incisor are respectively abutted against the alveolar side wall 10113.

The horizontal installation position of the veneer relative to the tooth refers to the installation position of the veneer on the labial surface of the tooth when the adhesive is ignored. Specifically, in combination with the XYZ coordinate axes in Figure 2, it can be seen that the horizontal installation position of the veneer relative to the tooth in the figure refers to the installation position of the veneer in two dimensions, the Y axis and the Z axis.

The vertical installation position of the veneer relative to the tooth refers to the installation position of the veneer relative to the labial surface of the tooth in a direction perpendicular to the labial surface of the tooth. Since the veneer and the labial surface of the tooth are filled with adhesive, there is a certain distance between the two. The vertical installation position is actually determined by the size of the distance. Specifically, in combination with the XYZ coordinate axis in Figure 2, it can be seen that the vertical installation position of the veneer relative to the tooth refers to the installation position of the veneer in the X-axis dimension.

Further referring to FIG. 1 , all the positioning tooth sockets 1011 are vertically through structures, and the crown ends of the positioning tooth sockets 1011 can discharge excess adhesive.

In order to facilitate the doctor to observe the bonding condition of the veneer, the present embodiment further has the following configuration: the labial side portion 103 is provided with an observation window 1031 connected to the positioning tooth socket 1011 .

It should be noted that the leftmost and rightmost positioning sockets 1011 are used to position molars, so the volume of these two positioning sockets 1011 is larger than the volume of the remaining positioning sockets 1011. Since molars are usually not installed with veneers, these two positioning sockets do not have corresponding observation windows 1031.

In addition, a plurality of guide plate connecting parts are provided on the outer side of the guide plate body 101 for connecting with the auxiliary positioning plate 2 . The specific structure of the guide plate connecting parts is described in Example 2.

Example 2

Please refer to Figures 3, 4 and 5. An auxiliary positioning plate used in conjunction with the veneer bonding guide plate as described above can also be produced by injection molding or 3D printing, and includes a positioning plate body 201. The positioning plate body 201 is worn on the teeth and is located at the root end of the veneer bonding guide plate 1. Its lingual side positions the vertical installation position of the veneer relative to the teeth.

Specifically, the lingual side of the positioning plate body 201 abuts against the labial surface of the veneer, which can limit the vertical distance between the veneer and the labial surface of the tooth. When in use, the positioning plate body 201 is closer to the neck of the veneer, which is used to position the neck of the labial surface of the veneer. The labial portion 103 of the veneer bonding guide plate is closer to the cutting end of the veneer, which is used to position the cutting end of the labial surface of the veneer.

The distance between the positioning plate body 201 and the lip side portion 103 can be adjusted as needed.

Continuing to refer to Figure 3, a number of neck positioning protrusions 202 are arranged at intervals on the lingual side of the positioning plate body 201. The shape and size of the neck positioning protrusions 202 match the triangular gap in the neck of the teeth and are used to fit into the triangular gap in the neck of the teeth. The fit between the neck positioning protrusions 202 and the triangular gap in the neck of the teeth realizes the positioning of the auxiliary positioning plate 1 and the teeth in the left and right directions.

Among them, the triangular gap structure at the neck of the tooth is shown in Figure 4.

Furthermore, a plurality of positioning plate connecting parts are arranged at intervals on the positioning plate body 201 , and the positioning plate connecting parts are connected to the guide plate connecting parts of the veneer bonding guide plate 1 , so that the veneer bonding guide plate 1 and the auxiliary positioning plate 2 form a whole.

In this embodiment, the positioning plate connection part is a buckle 203, one end of the buckle 203 has a plug 2031, the maximum cross-sectional area of the plug 2031 is greater than the maximum cross-sectional area of the main body of the buckle 203, the guide plate connection part is a slot 1032, the notch of the slot 1032 faces the lip side, the main body of the buckle 203 is inserted into the slot 1032 through the notch, the buckle 203 can adjust its installation position on the slot 1032 in the up and down direction, in this way, the spacing between the auxiliary positioning plate 2 and the veneer bonding guide plate 1 can be adjusted, the plug 2031 of the buckle 203 is located at the crown end of the slot 1032, when the positioning plate body 201 is at the position with the largest spacing from the guide plate body, the plug 2031 is blocked with the crown end of the slot 1032, and the plug 2031 can prevent the auxiliary positioning plate 2 from accidentally falling off. In addition, the positioning plate connection part can also be set as the slot 1032, and the guide plate connection part can be set as the buckle 203.

In addition, the connection between the veneer bonding guide plate 1 and the auxiliary positioning plate 2 can also adopt the connection method between the second guide plate and the first guide plate in patent CN216933522U.

The use process of veneer bonding guide plate 1 and auxiliary positioning plate 2:

First, apply adhesive to the veneer and/or the labial surface of the tooth, stick the veneer on the tooth one by one, then put the veneer bonding guide plate 1 on the patient, and then press the veneer toward the crown end to position the cutting end of the veneer. At this time, part of the veneer and the corresponding part of the tooth neck need to be pressed and adjusted. The pressing adjustment has two purposes: one is to allow the veneer to find a suitable position on the tooth neck, and the other is to squeeze out the excess adhesive by pressing. The doctor manually pressing the first veneer one by one is inefficient, and because the position of the cutting end of the veneer has been fixed, it is equivalent to the cutting end of the veneer having a fulcrum. If the veneer is pressed too hard at this time, the veneer may break. Therefore, the present invention proposes to achieve pressing and adjusting the corresponding parts of the veneer and the tooth neck through the auxiliary positioning plate 2. The specific operation is to put the auxiliary positioning plate 2 on the patient's teeth. The auxiliary positioning plate 2 is clamped with the clamping groove 1032 of the veneer bonding guide plate 1 through the buckle 203. The auxiliary positioning plate 2 is supported by the veneer bonding guide plate 1. The neck positioning protrusion 202 of the auxiliary positioning plate 2 is embedded in the triangular gap of the tooth neck. The auxiliary positioning plate 2 plays a role in positioning the veneer neck. During operation, all veneers can be pressed by slightly pressing the auxiliary positioning plate 2. Excess adhesive flows away from the overflow port. All veneers are subjected to force together, which can avoid veneer breakage. Finally, the veneer is cured.

It should be noted that the auxiliary positioning plate 2 can also be worn directly on the teeth without being connected to the veneer bonding guide plate 1. In this case, the doctor needs to press the auxiliary positioning plate appropriately to prevent the auxiliary positioning plate 2 from falling off.

Example 3

Please refer to Figures 6 and 7, a pressing tool for veneer bonding includes a pressing head 601, an elastic element 602 and a shell component 603. The pressing head 601 is slidably matched with the shell component 603, and its front end is against the veneer to provide pressing force for the veneer. The elastic element 602 is arranged on the shell component 603 to provide elastic force for the pressing head 601.

It can be understood that in the above technical solution, the present embodiment is provided with structures such as a pressing head 601, a housing assembly 603, and an elastic element 602. The pressing head 601 can press the veneer, and the elastic element 602 can make the doctor's pressing force on the veneer more controllable, more accurate and stable, and less prone to misoperation, thereby achieving the following purposes:

1) The veneer will not break due to excessive pressure;

Furthermore, the pressing head 601 is a micro vibrator, preferably a rod-shaped structure, and other shapes may also be used. A switch 604 and a power module 605 are set on the shell assembly 603. The micro vibrator, the power module 605 and the switch 604 are electrically connected in sequence through wires. The switch 604 controls the operation of the micro vibrator, and the power module 605 supplies power to the micro vibrator.

Among them, the micro vibrator can make the adhesive on the veneer more uniform and enhance the bonding effect. Specifically, when the micro vibrator is pressed on the veneer, the adhesive between the veneer and the tooth is spread more evenly through vibration. Switch 604 can control the start and stop of the micro vibrator. In some embodiments, switch 604 can also increase the gear position to control the vibration frequency and amplitude of the micro vibrator.

Continuing to refer to FIG. 7 , the housing assembly 603 includes a front housing 6032 , a middle housing 6033 and an end cover 6034 which are detachably connected in sequence from front to back. The detachable connection of the three can be achieved by interference fit, threaded connection and the like.

The front end of the front shell 6032 has a sliding hole connected to the outside, and the pressing head 601 is slidably and telescopically inserted into the sliding hole of the front shell 6032. The front end of the pressing head 601 can extend from the sliding hole of the front shell 6032, and the extended part is used to resist the veneer.

Slide bars 6011 are respectively arranged on both sides of the pressing head 601. The structural form of the slide bar 6011 is not limited to a rod shape, but may also be a block shape, etc. Windows 6031 connected to the outside are respectively opened on both sides of the front shell 6032. The slide bar 6011 is slidably connected to the corresponding window 6031. When the pressing head 601 slides, the doctor can see the slide bar 6011 sliding on the window 6031 from the outside, and the size of the pressing force can be judged by the position of the slide bar 6011 on the window 6031.

In some embodiments, a scale can be set on the window 6031, which is more convenient for the doctor to grasp the size of the pressing force. In addition, a scale can also be set on the pressing head 601, which is also convenient for the doctor to grasp the pressing force.

A partition 60331 is provided in the middle of the middle shell 6033, and a spring seat 60332 is provided in front of the partition 60331. The partition 60331 divides the inner cavity of the housing assembly 603 into two parts, the front half is used to accommodate the elastic element 602 and the pressing head 601, and the rear half is used to accommodate the power module 605. A through hole for the power line to pass through is provided on the partition 60331. The elastic element 602 is preferably a spring, one end of which is connected to the spring seat 60332, and the other end is connected to the pressing head 601.

In some embodiments, the elastic element 602 may also be a spring or other structure.

The switch 604 is passed through the end cover 6034, and the rear end of the switch 604 is exposed from the end cover 6034 for human operation.

The operation of pressing the veneer using this embodiment is as follows: the doctor holds the shell assembly 603, aligns the pressing head 601 with the veneer and presses vertically. The doctor can observe the position of the slide bar 6011 on the window 6031 while pressing, so as to adjust the force to keep the pressing force within an appropriate range.

This embodiment can be used alone or in conjunction with embodiment 1 and embodiment 2. When used in conjunction with embodiment 1 and embodiment 2, first apply adhesive to the veneer and/or the labial surface of the teeth, attach the veneers to the teeth one by one, and then press the veneer with a pressing tool 6 to squeeze the adhesive, remove bubbles, and make the adhesive more uniform. Then, put on the veneer bonding guide plate 1, and further press the veneer with the pressing tool 6 to put the veneer in place as much as possible. Then, put on the auxiliary positioning plate 2, and finally cure the veneer.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
