Description

Improved composite dental arch splint Technical Field The application relates to the technical field of medical appliances, in particular to an improved composite dental arch splint. Background Dental trauma mainly involves the front teeth and has become one of the common and frequently occurring diseases of oral emergency. The main fixation mode of past dental trauma has been along the treatment of jawbone fractures in oral and maxillofacial trauma, i.e. the firm fixation of dental arch splint-wire ligation. Physiological fixation, i.e. elastic fixation, of dental traumas has been more emphasized in recent years. With the advent of bonding technology and photo-curing composite resin in the 60 th century of 20, there has been a great progress in the dental trauma fixing method. The composite resin splint is fixed on clinic and is easy to operate and has beautiful appearance. The prior art CN 212281751U discloses a tooth dislocation fixing device, which comprises a resin dental arch splint and a light-cured resin unit, wherein the light-cured resin unit is fixed on the surface of an abutment tooth and a reset tooth lip, and the resin dental arch splint is sequentially and fixedly connected with all the light-cured resin units. When in use, the dental floss is used for measuring the use length, and the scissors are used for cutting the fiber dental arch splint with correct length in the package for standby. The method has the defects that the fiber dental arch splint with the correct length is required to be cut from the package for standby, and the fiber dental arch splint is generally formed by weaving a plurality of strands of quartz fibers in a multi-directional rope shape, and the tail end is easy to crack during cutting, so that the fiber dental arch splint is separated and dispersed, and the subsequent use is influenced. Therefore, there is a need for an improved composite arch splint that solves the above-identified problems. Disclosure of utility model The application provides an improved composite dental arch splint, wherein the tail end of the fiber dental arch splint is not easy to crack when being sheared and used, so that the fiber dental arch splint can be prevented from being scattered and further the follow-up use is not influenced. In order to solve the problems, the application provides an improved composite dental arch splint which comprises a metal dental arch splint and a fiber dental arch splint, wherein the fiber dental arch splint is wrapped on the periphery of the metal dental arch splint, and an anti-cracking component for preventing the fiber dental arch splint from cracking during shearing is arranged between the fiber dental arch splint and the metal dental arch splint. The fiber dental arch splint comprises quartz fibers, and a plurality of strands of the quartz fibers are woven in a multi-direction rope shape on the periphery of the metal dental arch splint to wrap the metal dental arch splint. The anti-cracking component comprises a plurality of anti-falling ribs arranged on the metal dental arch splint, wherein the anti-falling ribs are sequentially distributed at intervals along the length direction of the metal dental arch splint, quartz fibers are sequentially and continuously wound on each anti-falling rib when being woven and wound on the periphery of the metal dental arch splint, and knotting treatment is further carried out on each anti-falling rib. Preferably, the anti-falling rib is provided with barbs. Preferably, the barbs are obliquely arranged on the metal dental arch splint. Preferably, the barb is made of stainless steel. Preferably, the metal dental arch splint is made of stainless steel. Preferably, the fiber dental arch splint is fixed on the tooth surface through a light-cured resin unit. The beneficial effects are that: The application provides an improved composite dental arch splint, which wraps a metal dental arch splint by a fiber dental arch splint, an anti-cracking component is arranged between the fiber dental arch splint and the metal dental arch splint, and the tail end of the fiber dental arch splint is not easy to crack, namely is not easy to be separated when the fiber dental arch splint is sheared from the package for use through the use of the anti-cracking component, so that the follow-up use is not influenced.
