Abstract: Data match coding system for orthodontic appliances are disclosed. One variation of a data match code apparatus may generally comprise a three-dimensional model corresponding to a patient dentition and a platform extending from the three-dimensional model. The platform may define a data match code having a plurality of through-holes which are positioned relative to one another in a predetermined pattern.

Abstract: A semiconductor laser system for laser medical cosmetology, comprising a semiconductor laser array (1), an optical waveguide (2), a boss-shaped transparent contact window (3) located at the light outlet end of the optical waveguide (2), and a refrigeration block (4) for conduction cooling of the contact window (3); the refrigeration block (4) consists of a base portion and a hollow head above the base portion; the front part of the hollow head presses against and is tightly fastened to the whole side wall of the contact window (3); the light outlet end of the optical waveguide (2) is located in the cavity of the hollow head, and has a gap between the waveguide and the inner wall of the hollow head; a thermoelectric semiconductor refrigerator (5) is disposed below the base portion of the refrigeration block (4); a first water supply block (6) is disposed below the thermoelectric semiconductor refrigerator (5); and a second water supply block (16) for heat dissipation is installed in the semiconductor laser arr

Abstract: Disclosed is a bilateral cooling type semiconductor laser system for medical beauty use, the contact window of which can make direct contact with the skin. The bilateral cooling type semiconductor laser system for medical beauty use comprises a semiconductor laser array, an optical waveguide located on the front end of the light emitting surface of the semiconductor laser array, a transparent contact window abutting against the light outlet end of the optical waveguide, a pair of cooling blocks and a first water throughflow block. The first water throughflow block is divided into a basal part and a U-shaped head located above the basal part, and the middle part and back part of the optical waveguide are embedded in the U-type header. A fixed block is provided above the corresponding optical waveguide to press and fix the optical waveguide. There is still a space between the optical waveguide and the side wall of the U-type header.
