The purpose of this study was to evaluate the influence of heating, cast bonding, and subsequent polishing procedures on attractive force of magnetic attachments. Two magnetic attachment systems with keepers of different chemical compositions (Hicorexslim 3013, 447J1; Magfit EX400, AUM20) were employed. Keepers examined were: (1) untreated; (2) heated; (3) cast-bonded with Ag-Pd alloy; (4) cast...
Background and Aims: As in fissure sealant therapy the tooth surface is mostly enamel, the use of an enamel bonding agent (hydrophobic bonding agent) may be more cost effective than that of newer generations of bonding (hydrophilic bonding agents). The aim of this study was to compare the retention and durability of fissure sealant therapy when applying an enamel bonding agent, a dentin bondi...
Metakaolin (MK) prepared by the calcination of kaolin at 550 °C and fly ash (FA) from combustion black coal in a granulating boiler were used to prepare unfired ceramic bonding systems via alkali activation process. A long-term stability mechanical properties samples similar was observed. The optimal metakaolin ratio, type activator (NaOH or water glass) its concentration evaluated after hydrat...
Wafer bonding is an emerging technology for fabrication of complex three-dimensional (3D) structures; particularly it enables monolithic wafer-level 3D integration of high performance, multi-function microelectronic systems. For such a 3D integrated circuits, lowtemperature wafer bonding is required to be compatible with the back-end-of-the-line processing conditions. Recently our investigation...
