Abstract: A method for making a hard clear aligner set for stepwise orthodontic treatment is provided. The hard clear aligner set includes plural intermediate aligners made as follows. First, original tooth-row image files corresponding to a patient's teeth are obtained. Tooth arranging software is then used to produce final tooth-row image files by rearranging the teeth in the original tooth-row image files, define the displacements and rotation angles required for the patient's teeth in each step of the treatment, and after computation, produce plural stepwise tooth-row image files. Following that, dedicated software is used to define the surface thickness in each stepwise tooth-row image file, thereby producing shell-like aligner image files corresponding respectively to the intermediate aligners. The shell-like aligner image files are subsequently converted into digital control instructions in order to control a multiaxial carving machine to carve hard clear aligners from hard polymeric modular blocks.

Abstract: The present invention provides a light detectable thermal-release pressure-sensitive adhesive and an application thereof. Heat-expandable foaming particles are added to a formula of the light detectable thermal-release pressure-sensitive adhesive, so that the product has high adhesion; moreover, after curing and molding, the adhesion can be greatly reduced by a heating process, so the problem that the existing high-adhesion pressure-sensitive adhesive film is not torn easily is solved; and meanwhile, by adding an inorganic fluorescent material, the light detectable thermal-release pressure-sensitive adhesive absorbs ultraviolet light and then can emit a visible wavelength to detect adhesive residues quickly; and by applying the light detectable thermal-release pressure-sensitive adhesive to a manufacture procedure, the adhesive residues are not occurred easily and thus the convenience of detecting the adhesive residue is increased.

Abstract: An invisible plastic teeth brace for orthodontics is disclosed herein. It mainly comprises a first side wall, a second side wall opposite to the first side wall, a dental crown upper wall for connecting upper edges of the first side wall and the second side wall, and an orthodontic groove jointly defined by the first side wall, the second side wall and the dental crown upper wall. At least one of the dental crown upper wall, a first part connecting the dental crown upper wall to the first side wall, and a second part connecting the dental crown upper wall to the second side wall has at least one hole or has a thickness less than a thickness of the first side wall and the second side wall.

Abstract: A tool magazine device includes a magazine body adapted to be disposed on a machine body of a machine tool to confront a working space, a plurality of insertion openings formed in a right side wall of the magazine body and each extending towards a left side wall of the magazine body to form a storage chamber, a plurality of gripping members fitted in the insertion openings for grippingly engage cutting tools, an inlet disposed in the magazine body for introducing therein a flow of pressurized air, and an air duct unit disposed on the left side wall and coupled to communicate the inlet with the storage chambers so as to permit the pressurized air to flow out of the insertion openings to thereby clean swarf from the cutting tools.
