Light curing machine for oral correction

Abstract

A photocuring machine for oral correction comprises a machine body and a light guide bar, a light guide shading head is arranged at the front end of the light guide bar, a light hole used for being connected with the light guide bar and a light shield used for shielding redundant light are arranged on the light guide shading head, and the light shield is in a strip shape and surrounds the periphery of the light hole. The light shield is provided with two side baffles and an end baffle arranged between the ends of the two side baffles, the two side baffles are used for covering the front side and the rear side of the tooth to be treated and the front side and the rear side of the side teeth respectively, and the two end baffles are used for abutting against the tooth end faces of the side teeth respectively; first elastic bags distributed in the length direction of the light shield are arranged on the inner sides of the side baffles, second elastic bags distributed in the width direction of the light shield are arranged on the end faces, used for abutting against side teeth, of the end baffles, and the first elastic bags and the second elastic bags are used for filling gaps between the light shield and the corresponding teeth after deformation and expansion. The blue light shielding mask not only has an excellent blue light shielding effect, but also is comfortable to use.

Description

technical field [0001] The invention relates to the field of stomatological medical equipment, in particular to a light curing machine for oral orthodontics. Background technique [0002] The light curing machine is an oral device for restoring teeth. It uses the principle of light curing to make the dental repair resin material rapidly solidify under the action of light waves in a specific wavelength range, so as to fill the cavity or bond the bracket. In the photocuring process, the photoinitiator absorbs photons of a specific wavelength, excites them into an excited state, forms free radicals or cations, and then through the transfer of intermolecular energy, the polymerizable prepolymers and photosensitive monomers become excited. State, to produce charge transfer complexes, these complexes are continuously cross-linked and polymerized, and in a very short time to produce high molecular polymers that solidify into a three-dimensional network structure, so that the repair...

Problems solved by technology

A slight looseness will cause the ring shading sleeve to miss the teeth and cause light leakage, which will not achieve the protective effect

[0007] Finally, if it needs to achieve a good shading process, that is, the doctor's operating hand and the patient's head need to maintain a fixed posture to avoid the loss of the annular shading sleeve. Usually, the doctor's hand and the patient's head are kept still, resulting in Physicians and patients are prone to muscle numbness and discomfort
