Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a dental moisture-proof molding device. Background Technology

[0002] In dental treatments such as fillings, restorations, and orthodontic procedures, maintaining a dry oral environment is crucial for ensuring treatment effectiveness. The presence of fluids such as saliva, blood, and tissue fluid can interfere with the bonding and curing of materials, affecting treatment quality. Traditional methods of moisture isolation primarily use cotton rolls, but these rolls are prone to shifting, have limited absorbency, and are difficult to maintain stably over extended periods.

[0003] Chinese Patent Publication No. CN220237096U discloses a dental moisture-isolating molding device. This device "comprising: a forceps body, which includes a clamping part, a fixing part, and a holding part. The holding part is movably connected to the fixing part. The clamping part is disposed on the holding part, and the clamping part can be opened or closed by pushing it along the fixing part. The end of the clamping part is provided with a clamping device for clamping the moisture-isolating element. This invention clamps the moisture-isolating element by setting a clamping device on the clamping part. During treatment, the clamping part can be moved towards the teeth by moving the holding part, thereby causing the moisture-isolating element located on the clamping device to fit against the teeth, thus achieving the function of moisture isolation."

[0004] The aforementioned device clamps the moisture-isolating component, allowing it to adhere to the teeth and achieve moisture isolation. However, when performing moisture isolation on a patient's oral cavity, medical personnel need to operate on the inside of the patient's mouth using clamping rods and fixing rods, which increases the patient's discomfort during treatment and limits the device's usability.

[0005] Therefore, a dental moisture-proof molding device is proposed to address the above problems. Utility Model Content

[0027] Example:

[0028] Please see Figure 1 - Figure 4A dental moisture-proof molding device includes a first dental arch plate 1, a second dental arch plate 2 mounted on the outer side of the first dental arch plate 1, both the first dental arch plate 1 and the second dental arch plate 2 are molded from medical-grade transparent thermoplastic polyurethane material, and positioning components for auxiliary fixation of the two dental arch plates are installed at both ends of the outer side of the first dental arch plate 1 and the second dental arch plate 2; a fixing block 5 is fixedly connected to the rear side of the middle of the outer wall of the second dental arch plate 2; a threaded rod 4 is rotatably connected to the middle of the outer wall of the first dental arch plate 1, the end of the threaded rod 4 is threaded to the inner wall of the fixing block 5; and telescopic rods 6 are fixedly installed at both ends of the outer wall of the first dental arch plate 1, the end of the telescopic rod 6 is fixedly connected to the front end of the outer wall of the second dental arch plate 2.

[0029] This solution uses thermoplastic polyurethane material to support the dental arch plates. Its elastic modulus allows it to bend and deform slightly, thus bending the dental arch plates into a shape that matches the curvature of the patient's jaw. The first dental arch plate 1 moves the fixing block 5 and the second dental arch plate 2 through the rotation of the threaded rod 4, so that the two dental arch plates fit against the sides of the teeth, allowing the two dental arch plates to be inserted into the patient's oral cavity, which facilitates the subsequent moisture-proof molding operation.

[0030] Please see Figure 1 and Figure 3 The positioning component includes an outer plate 3, which is U-shaped and has its opening facing the dental arch plate. Springs 31 are fixedly connected to both ends of the inner wall of the outer plate 3. The ends of the two springs 31 are fixedly connected to the outer walls of the first dental arch plate 1 and the second dental arch plate 2, respectively. Moisture-proof pads 7 are fixedly installed on the bottom walls of the first dental arch plate 1 and the second dental arch plate 2. The moisture-proof pads 7 are made of microfiber non-woven fabric.

[0031] This solution involves installing a U-shaped external plate 3 on the outer bottom of the first dental arch plate 1 and the second dental arch plate 2. The external plate 3 is connected to the two dental arch plates via springs 31 on both sides. When the threaded rod 4 moves the second dental arch plate 2, the springs 31 will expand and contract synchronously. The elasticity of the springs 31 controls the two dental arch plates to always apply a certain pressure to the teeth, thereby achieving an auxiliary positioning effect and ensuring the stability of the positioning of the dental arch plates and the moisture-proof pad 7. Since the ultrafine fibers have many micropores between the microfibers, forming a capillary structure, they have good water absorption, which can absorb the liquid in the oral cavity and reduce its impact on oral treatment.

[0032] Please see Figure 1 , Figure 2 and Figure 4The bottom wall of the moisture-proof pad 7 has a first guide channel 8 for concentrating the flow of liquid in the oral cavity. The first guide channel 8 extends to the outer wall of the first dental arch plate 1 or the second dental arch plate 2, and its ends are respectively provided with second guide channels 9 for diverting the liquid to the outside. The outer walls of the first dental arch plate 1 and the second dental arch plate 2 are each provided with a rectangular array of multiple hemispherical telescopic anti-slip protrusions 10.

[0033] This solution achieves V-shaped drainage through the first drainage channel 8 and the second drainage channel 9, concentrating the fluid inside the patient's oral cavity, introducing it through the first drainage channel 8, and then exporting it through the second drainage channel 9, preventing the fluid from flowing towards the teeth and affecting treatment and shaping; the anti-slip protrusion 10 is a hemispherical telescopic design, and its material can be silicone. The protrusion can increase the friction between the dental arch plate and the tooth surface, thereby further improving the stability of the dental arch plate positioning.

[0034] Working Principle: When oral treatment is required, medical staff slightly adjust the first dental arch plate 1 and the second dental arch plate 2 according to the actual condition of the patient's dental arch, so that the first dental arch plate 1 and the second dental arch plate 2 fit the curvature of the patient's dental arch. Then, the threaded rod 4 is manually rotated. The threaded rod 4 is rotatably connected to the first dental arch plate 1 through a positioning structure, so the first dental arch plate 1 will not move during the rotation of the threaded rod 4. Since the end of the threaded rod 4 is threaded to the inner wall of the fixing block 5, the fixing block 5 and the second dental arch plate 2 move horizontally during the rotation of the threaded rod 4. This allows the distance between the first dental arch plate 1 and the second dental arch plate 2 to be adjusted to match the patient's teeth. During the movement of the second dental arch plate 2 by the threaded rod 4, the telescopic rod 6 moves synchronously with the second dental arch plate 2, thus ensuring the overall positioning stability of the two dental arch plates. The threaded rod 4, the fixing block 5, and the telescopic rod 6 are all installed on top of the first dental arch plate 1 and the second dental arch plate 2. Sufficient space is reserved for the teeth to be inserted. Once the positions of the first dental arch plate 1 and the second dental arch plate 2 are determined, they are embedded in the patient's gums, so that the first dental arch plate 1 and the second dental arch plate 2 fit against the patient's teeth. During the process of fitting the dental arch plate against the teeth, the anti-slip protrusions 10 extend and retract along the teeth inward through a telescopic design, increasing the static friction with the tooth surface through microscopic deformation, thereby improving the stability of the contact between the dental arch plate and the teeth. At the same time, U-shaped external plates 3 are installed on both sides of the first dental arch plate 1 and the second dental arch plate 2. The external plates 3 are connected to the first dental arch plate 1 and the second dental arch plate 2 respectively through springs 31 on both sides of the inner wall. The elasticity of the springs 31 can ensure the fixation effect of the bottom of the two dental arch plates against the patient's teeth. Thus, the structure at both the upper and lower positions ensures the stability of the dental arch plate and the moisture-proof pad 7 fitting against the patient's gums. The moisture-proof pad 7 absorbs the liquid in the patient's oral cavity and can guide it through the first guide channel 8 to the second guide channel 9, thereby flowing to the outside of the teeth and avoiding affecting the tooth shaping effect.

[0035] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
