Title: Innovations by Inventor Seiji Kihara
Introduction
Seiji Kihara, an accomplished inventor based in Bizen, Japan, holds a total of four patents. His innovative contributions primarily focus on advancements in dental materials and orthodontic appliances, showcasing his expertise in the fields of biomedical engineering and materials science.
Latest Patents
Kihara's latest patents include a unique orthodontic appliance designed to enhance orthodontic treatment. This inventive appliance features a main body and a bonding base, both composed of calcium phosphate crystallizing glass. The composition of this glass includes specific percentages of CaO (10 to 60 wt %), P2O5 (25 to 85 wt %), Al2O3 (5 to 25 wt %), and Li2O (0.01 to 5 wt %). It possesses a Vickers hardness of 4.5 GPa or lower, with a bending strength of 100 MPa or higher, making it an excellent choice for dental applications.
In addition, Kihara has made significant strides in the development of glass ceramics utilized as dental materials and artificial bone substitutes. These glass ceramics contain alkali metal oxides (R2O) ranging from 0.01 to 25 parts by weight, strategically combined with a CaO-Al2O3-P2O5 system. The innovative casting process ensures that the molten fluid evenly distributes to internal mold corners, achieving low crystallization temperatures and brief crystallization durations. The produced crystalline structure exhibits exceptional strength and minimal internal defects.
