Operating Instructions Stand of the operating instructions 11 2009 1253 1 General Terms SOLIBOND N is a beryllium free Nickel Chrome Alloy Optimum Metal Ceramic bonding is provided due to the special oxide bonding SOLIBOND N is suitable for open flame melting as well as for high frequency casing one of the remarkable features is its high corrosion resistance Its composition has been well established for many years 1 1 Product Description Art 963 0250 SOLIBOND N 250g Delivery Art 963 1000 SOLIBOND N 1000g 1 2 Manufacturer YETI Dentalprodukte GmbH Industriestrasse 3 D 78234 Engen Gerrmany Tel 0049 7733 94100 Fax 0049 7733 941022 e mail adresse info yeti dental com Technical Questions 0049 7733 9410 20 2 Determinded use Metal to ceramic Nickel Chrome Alloy with high corrosion resistance and less oxide film to be used only by dental technicians or similary qualified people for dental restorations in the patient s mouth 3 Instructions for use 3 1 Modelling In order to reach a good casting of Solibond N the wall thickness of the modelling units should not be less than 0 45mm Please ensure that sprues with the right dimensions thickness amp reservoir are attached to the full cast crown and bridge parts 3 2 Bedding SOLIBOND N is compatible with Yetivest Art 932 0000 Duovest Art 952 0000 or any other phosphate bound commercial investments which can be pre heated up to 1 020 C following the manufactures ins

4. tructions A pre heating temperature of 900 C has proved to be good at the Praxis 3 3 Casting SOLIBOND N must be melted in a ceramic crucible using ventilation for removing of vapours Never use graphite crucibles Use always the same alloy with the same crucible and clean after use Flame and The neutral adjusted flame with Propan Oxygen or Azetylen Oxygen as well as High frequency the non use of the Flux prevents overheating of the alloy As soon as the melting last cast ingots have slumped the shade disappeared and immediately after opening tear of the oxide layer start the casting procedure 3 4 Cooling After casting let the muffle cool slowly down and at room temperature do not rinse with cold water Do not reuse already casted alloy Important ingredients for metal ceramic bonding will evaporate through the first melting of the alloy During re melting these components decrease and a sufficient metal ceramic bonding can no longer be guaranteed The units are finished using normal tungsten carbides and aluminium oxide stones The minimum thickness of the finished units schould be 0 2 mm To avoid any contamination while working with different alloys we suggest you use the same grinding instruments 3 5 Ceramic firing Oxide firing can be done in air at 980 C for 10min but it is not necessary or obligatory Next blast frames with 100 my Aluminium oxide and lean as usual with distilled water ultrasonic or stream cleaner Never use
