Abstract: PURPOSE: A method for forming a coating film for implant is provided, which enables excellent fusion with bone in the surface of implant by low temperature plasma process. CONSTITUTION: A method for forming a coating film for implant comprises: a step of removing foreign material adhered to the surface of implant; and a coating step of forming a coating film having amine radical by polymerizing reaction gas by the plasma in the surface of implant. In the coating step, ammonia(65) is used as the reaction gas. In the plasma polymerization, electricity is discharged while pressure is maintained at 50-100m torr and the reaction temperature is maintained at 20-25 deg.C.

Abstract: A method of forming a silver ion coating layer is provided to apply silver ions to an orthodontic device or to the surface of an implant, and to prevent the pathogenic oral microflora attachment that causes tooth-decay. A silver ion coating layer is formed by polymerization. To this end, a target part(35) fixed to a stabilizer is injected between both electrodes(31) inside a vacuum chamber(30), and a vacuum pump(20) is operated to make the chamber vacuum. The pressure in the chamber is measured by a pressure gauge(40). Under the vacuum condition, Ar or inert gas(60) is injected to clean the surface of a substrate. Acrylic acid gas(65) is introduced into the chamber as a monomer gas, and discharged with a generator(50). The discharge takes place in two steps, 80W for 4-6min and 30-40W for 15-25min. A resulting acrylic acid polymerization coating layer with a carboxylic group is immersed in a silver ion-containing solution for about 30minutes to substitute hydrogen ions with silver ions.

Abstract: An implant is provided to decrease propagation of bacteria by reducing a gap between a fixture and an abutment member and to increase bearing force of the abutment member for the fixture. An implant(10) is composed of a fixture(11) implanted in an alveolar bone and an abutment member(12) made of shape memory alloy and combined with the fixture by a combining unit(20) using deformable force generated by temperature difference of the shape memory alloy. The combining unit has a projection(21) formed at the upper end of the fixture and tapered in order to reduce the diameter gradually toward the lower side. A combining groove(22) is formed at the lower side of the abutment member to join with the projection and provided with the inside tapered to correspond to the projection.
