Abstract

This utility model discloses a special forceps for fixing loose teeth that can stabilize the resin fiber splint and prevent light scattering. It includes a forceps body composed of an upper body and a lower body arranged in parallel. The upper and lower bodies are respectively connected to an upper clamping part and a lower clamping part at their bottoms. The upper surface of the upper clamping part has a curing lamp housing, the lower surface of the upper clamping part has a splint placement opening, and the upper surface of the lower clamping part has an elastic plastic pad. The entire utility model is made of opaque stainless steel, which blocks scattered light when the curing lamp is operating, protecting the eyes. Furthermore, the circular placement hole and light-emitting hole in the curing lamp housing allow light to directly illuminate the target location, preventing the elastic fiber-composite resin splint outside the curing lamp housing from hardening. The combined action of the splint placement opening and the elastic plastic pad prevents the elastic fiber-composite resin splint from slipping, achieving a good adhesive fixation of the affected tooth.

Description

Technical Field

[0001] This utility model relates to the field of clinical application in oral medicine, specifically a special forceps for fixing loose teeth that can stabilize resin fiber splints and prevent light scattering. Background Technology

[0002] Elastic fiber-composite resin splints are currently the most widely used tooth stabilization devices in clinical practice. They belong to the category of elastic splint fixation techniques for tooth stabilization and are primarily used for dental trauma, including root fractures and tooth avulsion. This technique utilizes the principle of adhesion. During application, the tooth surface is treated with acid etching and an adhesive. A flowable resin is then applied in dots to the tooth surface, and the elastic fiber-composite resin splint is bonded to the tooth surface. Forceps are used to press the splint firmly against the tooth surface. After the splint stabilizes, it is cured in sections using light curing. This process is repeated on other adjacent teeth until the injured tooth and the adjacent healthy teeth are fixed as a single unit. This allows the periodontal tissues of the tooth group to retain their functional reserves, maintaining a range of motion slightly greater than the physiological range of motion for the injured tooth. It also reduces the damage caused by excessive coinciding forces or lateral torsional forces, promoting periodontal healing and alveolar bone regeneration.

[0003] However, elastic fiber-composite resin splints have the following drawbacks: First, they cannot effectively block scattered light from dental curing lamps, causing adjacent splints to harden and lose their elastic deformation ability; second, because the tooth surface has a certain curvature, the splint is prone to slipping when using tweezers to press it firmly against the tooth surface, causing the final fixation site to deviate from the target location. Therefore, how to better perform loose tooth fixation operations while avoiding the loss of elasticity of adjacent splints due to the light source of the dental curing lamp during the operation is the main challenge facing research in this field. Utility Model Content

[0004] The purpose of this invention is to provide a special tweezer for fixing loose teeth that combines the functions of stabilizing the resin fiber splint and preventing light scattering, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A special tweezer for fixing loose teeth that can stabilize resin fiber splints and prevent light scattering includes a tweezer body composed of an upper body and a lower body arranged in parallel. The upper body and the lower body are respectively connected to an upper clamping part and a lower clamping part at their bottoms. The upper surface of the upper clamping part is provided with a curing lamp accommodating chamber, the lower surface of the upper clamping part is provided with a splint placement opening, and the upper surface of the lower clamping part is provided with an elastic plastic pad.

[0007] Preferably, the upper clamping part and the lower clamping part are arranged horizontally in parallel.

[0008] Preferably, the angle between the upper clamping part and the upper body, and between the lower clamping part and the lower body, is 30-180°.

[0009] Preferably, the curing lamp housing is in the shape of an inverted trapezoid, and the upper middle part of the curing lamp housing has a circular placement hole.

[0010] Preferably, a light-illuminating through-hole is provided in the middle of the curing lamp housing.

[0011] Preferably, the tweezers body, upper clamping part, and lower clamping part are all made of opaque stainless steel.

[0012] Preferably, the width of the clamp placement opening is 2-5mm.

[0013] Compared with existing technologies, the beneficial effects of this utility model are:

[0014] (1) The entire utility model is made of opaque stainless steel metal material. When the light curing lamp is in operation, it can block scattered light and protect the eyes. Furthermore, the light can be directly irradiated onto the target position through the circular placement hole and light illumination hole of the curing lamp housing, preventing the elastic fiber-composite resin sandwich panel outside the curing lamp housing from being cured and hardened.

[0015] (2) The present invention can stably place the elastic fiber-composite resin splint on the tooth surface through the combined action of the splint placement port and the elastic plastic pad, preventing the elastic fiber-composite resin splint from slipping off, thereby making the elastic fiber-composite resin splint tightly attached to the tooth surface, so as to achieve a good bonding and fixing effect on the affected tooth.

Detailed Implementation

[0024] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0025] Please see Figure 1-7 A special tweezer for fixing loose teeth that can stabilize resin fiber splints and prevent light scattering includes a tweezer body composed of an upper body 1 and a lower body 2 arranged in parallel. The upper body 1 and the lower body 2 are respectively connected to an upper clamping part 3 and a lower clamping part 4 at their bottoms. The upper surface of the upper clamping part 3 is provided with a curing lamp accommodating chamber 5, the lower surface of the upper clamping part 3 is provided with a splint placement opening 6, and the upper surface of the lower clamping part 4 is provided with an elastic plastic pad 7.

[0026] The upper clamping part 3 and the lower clamping part 4 are arranged horizontally in parallel.

[0027] The angle between the upper clamping part 3 and the upper body 1, and between the lower clamping part 4 and the lower body 2, is 30-180°.

[0028] The curing lamp housing 5 is generally inverted trapezoidal, and the upper middle part of the curing lamp housing 5 has a circular placement hole 11.

[0029] A light-illuminating through-hole 8 is provided in the middle of the curing lamp housing 5.

[0030] The tweezers body, upper clamping part 3, and lower clamping part 4 are all made of opaque stainless steel.

[0031] The width of the clamp placement opening 6 is 2-5mm.

[0032] When fixing teeth using the aforementioned tweezers for fixing loose teeth that can stabilize resin fiber splints and prevent light scattering, the dental light curing lamp is fixed in the curing lamp housing 5, and then the elastic fiber-composite resin splint 10 is placed in the splint placement opening 6. The splint placement opening 6 and the elastic plastic pad 7 work together to prevent the elastic fiber-composite resin splint 10 from slipping off due to the certain arc shape of the tooth surface. After the tooth surface 9 is treated with acid etching and adhesive, a flowable resin is dotted on the tooth surface 9. Then, the elastic fiber-composite resin splint 10 is bonded to the tooth surface 9 using the tweezers of this invention. The elastic plastic pad 7 can stabilize the tooth surface 9 and the elastic fiber-composite resin splint 10. After clamping and stabilizing, the dental light curing lamp is turned on for light curing. The light from the dental light curing lamp shines directly on the target position through the light-illuminating hole 8 to prevent scattered light from causing adjacent splints to harden and lose their elastic deformation ability. The above steps are repeated on other adjacent teeth until the injured tooth and the healthy teeth on both sides are fixed into a whole, thereby completing the fixation of the loose tooth.

[0033] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
