According to statistics, periodontal disease, decayed teeth and irregular dentition are the most common three odontopathy diseases in China at present, various sequelae of the three odontopathy diseases, such as tooth defects, gum swelling and pain and tooth extraction, also trouble people, and 90 percent of people suffer from gingivitis and periodontitis with different degrees. In the past, due to the restriction of economic development level and oral hygiene concept and consciousness, the understanding and cooperation degree of Chinese people on early treatment and preventive treatment are obviously lagged behind in developed countries. In recent years, with the improvement of living standard of people and the enhancement of treatment consciousness of patients, the dental clinic and scientific research of China are unprecedented, and the dental materials are rapidly developed.
As the dental material, gold alloy, Ni-Cr alloy, Co-Cr alloy, stainless steel, etc. are mainly used. The price and color of gold alloys limits their use. Ni-Cr alloys, Co-Cr alloys, and stainless steels are gradually being eliminated because they contain harmful elements such as Ni, Co, and Cr, and titanium alloys have a low density, a high specific strength, and excellent biocompatibility and corrosion resistance as compared to these materials, and thus a titanium alloy for dental use is urgently needed.
