UN STUDIO DEL FORTIA ADHESIVE DE PORCELLANA DENTAL FUSIONATE A METALLO.-Pro evalutar le effecto del atmosphera in le furno super le fortia ligatori, 12 specimens pro tests del fortia tensil de metallo describite in Specification No. 14 del ADA esseva preparate con un strato uniforme de material ceramic fusionate al barra. In 3 del specimens le material ceramic esseva fusionate in aere, in 3 in un vacuo, in 3 in oxygeno, e in 3 le nude metallo passava a transverso le cyclo de ignition. Le specimens manipulate sub oxygeno produceva le plus alte valores de fortia ligatori, e le specimens manipulate in vacuo produceva le valores le plus basse.
