Transillumination type oral cavity photosensitive resin laser curing lamp

Abstract

The invention discloses a transillumination type oral cavity photosensitive resin laser curing lamp which comprises a shell, a semiconductor laser, a control circuit board, a power supply assembly and a light guide rod, a light outlet hole is formed in the front end of the shell and connected with the light guide rod, the semiconductor laser is arranged on the front side in the shell, and the power supply assembly is arranged on the rear side in the shell and connected with the light guide rod. A control circuit board is arranged between the semiconductor laser and the power supply assembly, the power supply assembly is electrically connected with the semiconductor laser and the control circuit board, and blue electromagnetic waves output by the semiconductor laser are guided by the light guide rod and then are projected on the front and back surfaces or the side back surfaces of the teeth to be filled with the light-cured resin. Blue electromagnetic waves emitted by the transillumination type oral cavity photosensitive resin laser curing lamp are indirectly or directly transmitted to the front face or the back face or the side face of a tooth filling material to be cured, the penetration depth of tooth tissue or photosensitive resin is increased, meanwhile, the contact face of the photosensitive resin and a tooth cavity is preferentially closed, the occurrence rate of micro-permeation is reduced, and the tooth filling effect is improved. And the light curing effect is improved.

Description

technical field [0001] The present application relates to the technical field of oral medicine, in particular to a transilluminated oral cavity photosensitive resin laser curing lamp. Background technique [0002] Dental caries, commonly known as tooth decay and tooth decay, is a bacterial disease characterized by high incidence and wide distribution. It is the main common disease of the oral cavity and one of the most common human diseases. The World Health Organization has listed it alongside tumors and cardiovascular diseases Prevent and control diseases for the three major human beings. The purpose of caries treatment is to terminate the disease process and restore the original shape and function of the tooth. [0003] In 2000, FD I (World Dental Federation) vigorously advocated "minimally invasive treatment", which is based on minimally invasive dental treatment, that is, to minimize the cutting as much as possible and reduce the loss of tooth tissue as much as possibl...

Problems solved by technology

[0005] In comparison, many traditional repair methods have their own advantages and disadvantages: amalgam has high hardness and strong pressure resistance, but has no adhesiveness (no two-way pulling), only relies on mechanical insertion force, has creep, and has certain corrosion and toxicity, the analysis of leached matter found that mercury, silver, copper, and zinc were leached; glass ionomer cement has good adhesion, but poor hardness, no wear resistance, and easy to change color; inlays (including alloys, plastics, baked Porcelain, etc.) restoration, crown-post crown-core restoration, metal shell crown and porcelain crown restoration and other methods are widely used clinically, but the tooth preparation wears a lot, and the process is complicated and the cost is high

[0017] Clinically, in order to reduce microleakage, many companies have also carried out optimization attempts, mainly including: increasing light intensity, producing 3-second and 5-second curing lamp technology, but the observation results of mainstream literature: the microleakage at the edge of the tooth cavity Reduced, but the microleakage at the bottom increased, and even penetrated through the pulp cavity, so most clinicians do not approve

Secondly, intermittent pulsed light irradiation or gradually weak and then strong light irradiation is used to prolong the light time, allowing the elasticity of the tooth tissue itself to digest and absorb the mechanical structure imbalance caused by the shrinkage stress of the resin. Reduced microleakage at the bottom of the cavity, but increased microleakage around the cavity
