Description

Technical Field

[0001] The invention relates to the technical field of clinical application of oral medicine, and in particular to a special device for a dental light curing lamp with both the functions of stabilizing a resin fiber splint and preventing scattered light. Background Art

[0002] In the current field of clinical stomatology, elastic fiber-composite resin splints, as a widely used loose tooth fixation device, occupy an important position in loose tooth fixation technology, and belong to the category of elastic splint fixation. This technology mainly plays a role in the treatment of dental trauma, which covers common situations such as root fractures and tooth dislocations. Its core technical principle is based on bonding. By firmly bonding the elastic fiber-composite resin splint to the tooth surface, the injured tooth and the healthy teeth on both sides are connected and fixed into an organic whole. In this way, the functional reserve power of the periodontal tissue of this group of teeth can be fully mobilized, so that the injured teeth can maintain a range of motion slightly larger than the physiological mobility of normal teeth, while effectively reducing the damage caused by excessive bite force or lateral torsional force on the traumatized teeth, creating extremely favorable conditions for the smooth healing of periodontal tissues and the regeneration of alveolar bone.

[0003] In terms of the specific operation process, loose tooth fixation has a rigorous set of steps. First, the tooth surface must be etched and treated with adhesives. This step is like laying a solid foundation for subsequent operations and can enhance the adhesion between the tooth surface and other materials. Subsequently, the flowing resin is applied in a dotted manner on the tooth surface. These resins are like "small anchor points" that provide initial support for the fixation of the splint. Next, the elastic fiber-composite resin splint is placed on the tooth surface. At this time, tweezers are used to press the splint firmly so that it fits tightly on the tooth surface. After the position of the splint is stable, the splint is light-cured in sections, and light of a specific wavelength is used to induce the polymerization reaction of the resin, so that the splint is fixed and formed. According to this step, the operation is repeated on other adjacent teeth in turn until multiple teeth are tightly combined with the splint to form a stable whole.

[0004] However, despite the widespread clinical application of this technology, the existing fixation technique is not perfect and there are still some problems that need to be solved. On the one hand, during the light curing operation, the scattered light from the dental light curing lamp cannot be effectively shielded. These scattered lights will inadvertently irradiate the adjacent splint parts, causing the adjacent splints to cure prematurely, thereby losing their original elastic deformation ability, which not only affects the overall performance of the splint, but may also have an adverse effect on the fixation effect and subsequent recovery of the teeth. On the other hand, since the tooth surface is not flat, but presents a certain arc, this brings great difficulties to the operation. In the process of using tweezers to press the splint tightly against the tooth surface, the tweezers can easily slip due to the arc of the tooth surface. Once slipped, it is very likely that the final fixed part will deviate from the originally set target part, which greatly reduces the fixation effect, and may even require re-operation, which brings unnecessary pain and trouble to the patient, and also increases the difficulty and time cost of the doctor's work.

[0005] Therefore, how to better perform the loose tooth fixation operation while avoiding the loss of elasticity of the adjacent splint due to the light source of the dental light curing lamp during operation is a major challenge faced by the technical field. Summary of the invention

[0006] In order to solve the problem that in the operation of using elastic fiber-composite resin splints to fix loose teeth, the scattered light of the dental light curing lamp will cause the adjacent splints to solidify, thereby losing the ability of elastic deformation, reducing the elastic deformation ability of the splint, and making it impossible for the traumatized tooth to maintain a range of motion slightly greater than the physiological range of motion of the tooth; because there is a certain arc on the tooth surface, the splint is easy to slip when it is pressed tightly against the tooth surface with tweezers, causing the final fixed position to deviate from the target position. The present invention provides a light blocking device structure of a dental light curing lamp, and also needs to be able to stabilize the elastic fiber-composite resin splint.

[0007] The present invention provides a special device for a dental light-curing lamp with both the functions of stabilizing a resin fiber splint and preventing scattered light, comprising: a light-blocking body and an elastic ring; wherein both ends of the light-blocking body are open and connected; one end is open and provided with a curing lamp slot, and the other end is open and provided with a splint slot and an operating port; the curing lamp slot is used to connect an external curing lamp; the width and depth of the splint slot match the elastic fiber-composite resin splint; and the elastic ring is arranged in the curing lamp slot and is used to apply elastic force to the curing lamp.

[0008] In the present invention, the inner wall of the light-blocking body from the opening of the curing lamp slot to the middle waistline has an arc, and the inner diameter gradually decreases inwardly. Preferably, the inner diameter of the inner wall at the starting point of the arc is 8 mm.

[0009] In the present invention, an annular boss is arranged near the operation port; the annular boss is used to block extra light, and the center of the annular boss is arranged as an irradiation area with a diameter of 4-5 mm.

[0010] In the present invention, the light-blocking body is made of orange acrylic material.

[0011] Preferably, an identification portion is provided on the outer wall of the light-shielding body; the identification portion is provided near the operation port for quickly distinguishing the front and back and / or the front and back.

[0012] Preferably, the distance between the mid-waistline and the opening of the splint slot is 8 mm.

[0013] Preferably, the outer diameter of the light-shielding body is 9 mm, and the height is 15 mm; the operating port (13) is 5 mm high and 5 mm wide; and the clamping slot (12) is 3 mm wide and 0.6 mm high.

[0014] Compared with the conventional operation steps of directly using the elastic fiber-composite resin splint, the special device of the present invention can not only avoid the adjacent splints from being cured and hardened due to scattered light exposure, and only irradiate within the working range of 4-5mm, but also the operation port design of the device can also use tweezers to press the elastic fiber-composite resin splint against the tooth surface, and make it adhere to the tooth surface through the light source inside the device, thereby achieving the effect of elastic fixation in loose tooth fixation.

[0015] The present invention can reduce the operational sensitivity of using elastic fiber-composite resin splints to fix loose teeth by using a dental light curing lamp dedicated device that has both the function of stabilizing resin fiber splints and preventing scattered light. In addition to the function that each splint part that is not affected by scattered light can maintain elastic deformation, it can also effectively stabilize the splint on the tooth surface to prevent the splint from accidentally slipping off before being illuminated. The dental light curing lamp dedicated device that has both the function of stabilizing resin fiber splints and preventing scattered light can illuminate a splint part on a tooth surface while preventing the scattered light from causing the adjacent splint to be cured and lose elasticity.

[0016] The device of the present invention has the following characteristics:

[0017] 1) The overall structure of the device is made of a visible light-proof composite resin material (orange), which can not only prevent the splint outside the head cover from being solidified, but also allow the user to check from outside the head cover whether the splint is in close contact with the tooth surface. The material also has the function of protecting the eyes.

[0018] 2) The side of the bottom end of the device structure is designed as a clamping plate slot, which not only accommodates the extension of the clamping plate, but also stabilizes the clamping plate and prevents it from slipping.

[0019] 3) An operating port is designed at the front bottom of the device structure to provide operating space for the tweezers so that the tweezers can firmly clamp the traumatized tooth. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example 1

[0029] The present invention provides a special device for a dental light curing lamp with both the functions of stabilizing a resin fiber splint and preventing scattered light, the core components of which are a light blocking body 1 and an elastic ring 2.

[0030] Light blocking body 1

[0031] The two ends of the light shielding body 1 are opened and connected to form a channel. A curing light slot 11 is set at one end of the opening. In actual application, after the external curing light is inserted into the opening, it is tightly clamped by the elastic ring 2 to ensure that the curing light will not shake after installation, ensuring the stability of the light emission direction.

[0032] The other end opening of the light-shielding body 1 is provided with a splint slot 12 and an operation port 13. The width and depth of the splint slot 12 are specially designed according to the size of the elastic fiber-composite resin splint. In this embodiment, the splint slot 12 is 3 mm wide and 0.6 mm high. When the elastic fiber-composite resin splint needs to be light-cured, the splint can be accurately inserted into the splint slot 12, so that the light emitted by the light-curing lamp can be accurately irradiated onto the splint for curing.

[0033] On the outer wall of the light shielding body 1, a marking portion 14 is provided just above the operation port 13. The marking portion 14 can be in various forms. In this embodiment, a triangular depression is used, pointing to the operation port, so that the operator can quickly distinguish the front and back / front and back during use. The operation port 13 faces the operator directly in front, which improves the accuracy and efficiency of the operation.

[0034] In the light-blocking body 1, the inner wall from the opening near the curing light slot 11 to the middle waistline 15 has a special curvature, and the inner diameter gradually decreases inward. The middle waistline is smaller than the outer diameter of the curing light, which is about 7.8mm. When the two are in contact, an interference fit will be generated to connect and fix them (the device has a few elastic properties, allowing it to fit tightly (no gap) naturally). The inner diameter of the curvature of the inner wall is designed to be 8mm. This inner diameter with a sloped profile is used to clamp the upper curing light (outer diameter 8mm) to stop moving downward, and maintain the optimal effective distance between the light and the workpiece ≈8mm.

[0035] The distance between the middle waistline 15 and the splint slot 12 is 8 mm.

[0036] An annular boss 16 is provided near the operation port 13, and a 5 mm diameter irradiation area is provided in the center of the annular boss 16. In actual light curing operation, the irradiation area can be accurately aligned with the part to be cured, and the annular boss 16 can effectively block additional light, preventing the light from irradiating the non-working areas at the left and right ends, thereby ensuring the accuracy of the light curing operation.

[0037] The light blocking body 1 is made of orange acrylic material. Acrylic acid (PMMA) has the same performance as the light blocking plate of the neck of the dental light curing lamp, and its color is orange. Its main function is to prevent the scattered blue light of the light curing lamp.

[0038] Elastic ring 2

[0039] The elastic ring 2 is arranged in the curing lamp slot 11. The elastic ring 2 is made of rubber, and the elasticity of the rubber is used to realize a shrinking function of the device, so that it fits firmly with the outer wall of the light curing lamp, provides stable support and fixation for the curing lamp, prevents the curing lamp from being displaced due to accidental collision or shaking during operation, ensures that the light curing lamp is always in the best working position, and ensures the stability of the light curing effect.
