Abstract:
PURPOSE: Provided is a bioabsorptive ceramic-polymer complex material for tissue engineering with teeth apatite and polymer used which mixes teeth apatite, polymer for tissue engineering and solvent to keep porosity on the surface and section so that it improves humidity absorption rate. CONSTITUTION: The production process of the bioabsorptive ceramic-polymer complex material for tissue engineering with teeth apatite and polymer used comprises the steps of: (i) extracting an inorganic material from teeth of human or animals and crushing them to prepare teeth apatite; (ii) selecting one material from PGA, PLA, PLLA, PLGA, chitosan and PHBV as bioabsorptive polymer; (iii) selecting one solvent from methylene chloride, chloroform, DMSO and week acid; and (iv) mixing 60-90wt% of bioabsorptive polymer and 10-40wt% of teeth apatite under the selected solvent to produce a ceramic-polymer complex material.

PURPOSE: A tooth observation mirror having a luminous body is provided to observe easily a dark portion in a process for diagnosing or treating a tooth by installing the luminous body at a mirror for observing the tooth. CONSTITUTION: A reflective mirror reception bracket(30) is used for receiving a reflective mirror(10). A lower cover(35) is combined with the first combination portion of a lower portion of the reflective mirror reception bracket(30). A body is formed with the reflective mirror reception bracket(30) and the lower cover(35). A handle(50) is combined with the reflective mirror reception bracket(30). The reflective mirror(10) is formed with a circular plate-shaped mirror. The first combination portion is formed at the lower portion of the reflective mirror reception bracket(30). The second combination portion is formed at side portion of the reflective mirror reception bracket(30).
