FIELD: medical engineering. SUBSTANCE: method involves manufacturing separate bridge unit pieces from dense agglomerated ceramic material coated with porcelain by applying powder metallurgy techniques and joining separate bridge unit pieces mechanically engageable to each other by means of melted glass mass put on parts to be connected. Melted glass wets ceramic substrate and fills void spaces between bridge unit pieces and makes engagement with ceramic material building in this way strong connection when cooling. EFFECT: high strength; optimum fit; improved esthetic result. 7 cl, 2 dwg
