| Summary: | 碩士 === 國立臺灣大學 === 口腔生物科學研究所 === 100 === Esthetics of the teeth is very important to patients. Tooth bleaching therapy is an important dental procedure for patients in recent years. Tooth discoloration may be caused by intrinsic discoloration or extrinsic discoloration. Tetracycline, aging factors, smoking, tea, red wine and deep colored food may also cause tooth discoloration. The effect of tooth bleaching becomes better with the changing of the bleaching method and agent.
Patents can raise this product''s value and comprehensive industrial information. The World Intellectual Property Organization (WIPO) statistics shows that an industry''s business model not only can be analyzed by using patent technology information, but also can be protected by obtaining patents properly.
The purpose of this study was to analyze the patents in dental material field to explore technologies of the tooth bleaching through patent map from GPSA . Firstly, we set up key words and patent portfolios to search Taiwan''s patents for the tooth bleaching from Taiwan''s patent database. According to the results of our patent searching, 77 tooth bleaching-related patents were found from 1986 to 2010. Through analysis of these data, we could investigate the development of tooth bleaching techniques in Taiwan and other countries.
The results showed that patents of tooth bleaching steadily increased year by year in Taiwan. Foreign companies and inventors had the advantages in tooth bleaching technology and patents. Tooth bleaching patents were mostly related to the people''s living requirement, and tooth bleaching patents are mostly related to bleaching formula.
In conclusion, by using patent analysis and patent map, this study suggests that the development of related instruments to improve the efficiency of tooth bleaching is very important. In addition, we can also apply patents for these newly developed instruments.
