Abstract

A dental stent according to an embodiment includes handles and clamps which are decouplably coupled to main stent bodies depending on a purpose of use, the handles and the clamps enabling dental treatment and surgery to be performed safely and accurately. The dental stent is configured to include main stent bodies that are located in a maxillary or mandibular arch except for a treatment-target and surgical site in the same maxillary and mandibular arch and have respective square connection notches which enable respective handles or clamps to be decouplably coupled to the main stent bodies selectively depending on a purpose; an elastic clip that is coupled to upper ends of the main stent bodies and imparts elasticity to the main stent bodies; and light curing resins that are formed on respective inner walls of the main stent bodies and take a dental impression.

Claims (17)

1. A dental stent comprising:

handles and clamps;

main stent bodies that are to be located in an oral cavity, the main stent bodies having square connection notches through which the handles and/or the claimed clamps are capable of being coupled to the main stent bodies, in a detachable manner;

an elastic clip that is coupled to the main stent bodies and imparts elasticity to the main stent bodies; and

light curing resins that are formed on respective inner walls of the main stent bodies and take a dental impression,

wherein the elastic clip has an inverted U-shaped body, in which legs of the inverted U-shaped body are formed to be inclined inward such that the main stent bodies are smoothly inclined inward when the lower end portions of the elastic clip are forced to be inserted into and coupled to respective fitting holes formed at upper ends of the main stent bodies.

2. The dental stent according to claim 1 , wherein the light curing resins have respective surface films formed on surfaces of the light curing resins, the surface film inhibiting excessive intrusion of the light curing resins filled inside into an undercut between teeth.

3. The dental stent according to claim 1 , wherein the clamps that are decouplably coupled to the main stent bodies have a fastening member screw-coupled to upper parts of the clamps and are tightly screwed by the fastening member to inhibit the main stent bodies from moving; and

the clamps have respective close-contact portions which are formed at lower parts and come into close contact with the square connection notches, respectively.

4. The dental stent according to claim 3 , wherein a camera is provided at a body of one of the clamps.

5. A dental stent comprising:

handles and clamps;

main stent bodies that are to be located in an oral cavity, the main stent bodies having square connection notches through which the handles and/or the claimed clamps are capable of being coupled to the main stent bodies, in a detachable manner;

an elastic clip that is coupled to the main stent bodies and imparts elasticity to the main stent bodies; and

light curing resins that are formed on respective inner walls of the main stent bodies and take a dental impression,

wherein the handles that are decouplably coupled to the main stent bodies have respective connection portions at lower ends which are decouplably coupled to the square connection notches; and

when the handles are coupled to the main stent bodies, a force applied to the handles causes the main stent bodies to overcome an elastic force of the elastic clip to cause separation of the main stent bodies relative to each other.
