Mouth-opening device custom-made through 3-dimensional printing

A custom-made device fabricated through 3-dimensional (3D) printing for opening mouth, comprising

• a first supporting body, comprising a first body, a first pivoting part and a first supporting part,
• wherein said first body has a first space;
• said first pivoting part extends out from a first end of said first body;
• said first supporting part extends out from a second end of said first body;
• and said first supporting body is deposed in said oral cavity;
• a second supporting body, comprising a second body, a second pivoting part and a second supporting part,
• wherein said second body has a second space;
• said second pivoting part extends out from a first end of said second body;
• said second supporting part extends out from a second end of said second body;
• and said second supporting body is deposed in said oral cavity;
• wherein said first and said second supporting bodies pivot with each other through said first and said second pivoting parts;
• and
• wherein said first supporting part is coordinated with said second supporting part to open and close said oral cavity;
• and
• a screw,
• wherein said screw has a third end pivoted in said first space of said first supporting body;
• said screw has a fourth end movable and operated at a various of angles to lean on in said second space of said second supporting body;
• and said screw is screwed with a nut,
• wherein an overall framework is printed out through 3D-printing after 3D-scanning an oral cavity to meet the shape of said oral cavity;
• and
• wherein, after said first and said second supporting bodies are in a closed state to be deposed into said oral cavity, a single hand rotates said nut screwed on said screw to open said oral cavity by propping said first supporting body against said second supporting body as a fixed end with the coordination of said second space which is bigger than said first space.
