The profile for a technical solution combined following assignments:

• The need of an extremely low air pressure
• Limiting the maximum air pressure to avoid “ snow drifts”
• Ability to regulate the air pressure on the hand piece
• Complete production of high-quality components of metal
• Sterilisation of canulas
• Supplied by electrical power only
• Instant access through “plug and play”
• Suitable angles of the canulas for easy to reach areas for every preparation
• Reliable mechanical socket connector function
• Suitable swirling of the powder in the bottle for a continuous powder application without interruptions
• Creates a redundancy e.g. creates a reserve system for the continuous work on the patient
• Low air humidity to avoid clumping of the powder
• Mobility of the unit within different areas of the praxis
• Immediate availability and mobility together with the cerec unit.
• Appealing design and easy to maintain surfaces
• Acceptable price in range of few CEREC restorations
• Long durable functionality of the unit in a “dentist’s life”
