抄録

As apparatuses used in prosthesis have recently been increasing in size and complexity, it has often become difficult to fabricate prostheses by one piece casting. Particularly, considering the complicated environment of the mouth in mastication and the need for the protection of the abutment teeth, fitness accuracy is an important factor and the used of fusion welding and brazing has become indispensable for successful fitness of the prosthesis. However, existing bonding techniques are subject to certain limitations and it was necessary to research techniques for improving accuracy.<BR>To deal with this problem, a coating deposit based on electrodeposition, which dose not spoil the characteristics of deposits metal and which can bond prosthesis apparatuses to similar materials without relying on indirect methods such as soldering or cast bonding was developed. In developing this technique, a deposit metal was treated physically and chemically, electro-deposition was made on the treated surfaces, and a tensile shear strength test was performed. Then the processes used in the treatment of the surfaces were analyzed by ESCA analysis and SEM observation. The results were as follows:<BR>1. This technique enables the coating deposition of deposits metal.<BR>2. Physical treatment consisting of sandblasting is the most effective method for improving the bonding strength.<BR>3. Chemical treatment consisting of hydrochloric or sulfuric acid treatment can both activate the deposits metal surface and improve the bonding strength.<BR>4. The deposit metal surface activation capability of hydrochloric acid is higher than that of sulfuric acid.
