Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and more specifically, it relates to an invisible denture. Background Technology

[0002] Invisible dentures are a special type of removable denture designed to provide a more discreet and aesthetically pleasing solution as an alternative to traditional removable dentures. They are commonly used to fill in areas of missing teeth, especially when patients wish to avoid traditional metal-framed removable dentures, significantly improving the aesthetics of the restoration.

[0003] In the late 20th and early 21st centuries, the concept of invisible dentures began to emerge. Initial designs primarily focused on using high-strength, transparent or semi-transparent elastic resin materials to create the base, which was then combined with aesthetically pleasing artificial teeth. Therefore, the finished product's surface required polishing to ensure it met the required quality standards.

[0004] Because invisible dentures primarily restore front teeth, the resin teeth are relatively small. Insufficient roughness at the root after polishing results in a weak bond with the resin base, making the teeth prone to falling out due to adhesive detachment. Therefore, manual wax wrapping is necessary to ensure sufficient contact area between the resin base and the artificial tooth, requiring highly skilled dental technicians.

[0005] Therefore, in view of this, we will study and improve the existing structure and its deficiencies to provide an invisible denture, in order to achieve a more practical purpose. Utility Model Content

[0006] To address the aforementioned technical problems, this invention provides an invisible denture that solves the issue of insufficient bonding strength between the invisible denture and the base resin, which can easily lead to tooth loss due to adhesive detachment.

[0007] The purpose and effect of this utility model of an invisible denture are achieved by the following specific technical means:

[0008] An invisible denture includes a base and a plurality of crowns disposed on the base. The crowns have connection holes. The base is connected to the crowns by invisible adhesive, with one end of the adhesive connected to the base and the other end filling the connection holes.

[0009] Furthermore, the crown has secondary holes on both sides of the connecting hole, and the connecting hole and the secondary holes form a cross-shaped hole.

[0010] Furthermore, one end of the connecting hole penetrates through the crown, and the other end is located inside the crown; the secondary hole penetrates both sides of the crown.

[0011] Furthermore, both the connecting hole and the secondary hole are tapered with an outer diameter greater than the inner diameter, forming a cross-shaped hole with the connecting hole and the secondary hole.

[0012] Furthermore, the base is provided with multiple connecting slots, and the crown is fitted into the corresponding connecting slot and connected to the base by invisible adhesive.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Through the connecting holes on the crown, the invisible adhesive fills the channels after being polished during the filling process, forming a stable structure similar to "steel bars intersecting in concrete". This provides additional tensile strength while the surface adhesive is bonded, making it more stable. Attached Figure Description

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 3 As shown:

[0025] This utility model provides an invisible denture, including a base 1 and multiple crowns 2 disposed on the base 1. Each crown 2 has a connecting hole 201. During fabrication, tooth alignment is first performed by using a hand-held grinder to create the connecting holes 201 on the crowns. This allows the invisible adhesive to fill the cavity of the connecting hole 201 during filling, resulting in a combination of the crown 2 and the base 1. During drilling, one end of the connecting hole 201 penetrates the crown 2, while the other end is located inside the crown 2. Secondary holes 202 penetrate both sides of the crown 2, creating a cross-shaped hole in the crown 2 (teeth). This improves the bonding strength, similar to "steel bars intersecting in concrete" forming a stable structure. It provides additional tensile force while the surface adhesive is applied, making it more stable. Figure 3 As shown, both the connecting hole 201 and the secondary hole 202 are tapered, resulting in cross-shaped tapered holes on the teeth. This makes drilling easier with the grinder, and the wider outer and narrower inner shape allows the adhesive to enter the channel more smoothly, achieving a stable effect.

[0026] After the filling is completed, the base 1 is connected to the crown 2 with invisible glue, with one end of the invisible glue connected to the base 1 and the other end filled with the cross-shaped conical hole.

[0027] After tooth alignment, a wax model is first created to fix the teeth in the correct position and maintain their aesthetic shape. Then, the adhesive is filled in. The base 1 has multiple connecting slots 101. The crown 2 is positioned in the corresponding connecting slot 101. The tooth with the "cross-shaped conical hole" is placed in the missing part of the base 1 (in the connecting slot 101). The invisible adhesive flows through the conical cross-shaped hole structure, which is larger on the outside and smaller on the inside. The adhesive initially flows to the base 1 and can also easily enter the channel from the larger port to the other port. Once the holes are filled with adhesive, it flows to other parts of the base 1, thus forming a one-piece mold.

[0028] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
