css - certified symbiotic system
From impression taking up to the tension-free,
precisely fitting prosthesis
(Product information: ► bredent-casting technique)
css is a certified system (in accordance with ISO 9001) for the production of precisely fitting dental prosthesis from impression taking all the way to integration.
Symbiotically (Greek „Symbiosis“ = Cohabitation, figuratively the cooperation) structured, it only functions if all parties work together for the mutual benefit, sensibly interacting like the cogs of a precision clockwork.
The System
The certified system consists of the:
1. Material symbiosis (PDF: ► Diagram [360 kb])
2. Standardization of work processes
Chemical and physically coordinated products (material symbiosis) are defined therein, and work processes (manuals „Optimized modeling, from impression taking to the one piece cast in combination technique“) are combined and standardized between dentist and dental technician in such a manner that precisely fitting, enduringly reproducible prosthesis are produced in an economic way.
These products are developed, manufactured and marketed by bredent in Senden, Germany under the highest quality requirements.
css is modularly structured, and continuously advanced and updated.
The Advantages
certified symbiotic system
- increases the precise fit of your dental and laboratorial prosthetic works through coordinated system solutions
- is immediately integratable as part of your existing or planned ISO certification

Fig. 6: brecision – impression material
brecision offers identical or better contraction values than a polyether impression material, combined with the advantages of an A silicone, e.g. easy demolding and pleasant taste.
No significant change in contraction after 2 hours.

The contraction of impression materials can be
determined with the KoEx measuring device.

Optimized Modelling
describes the fabrication procedure from impression taking to the completed prosthetic restoration in two parts. Using a flowchart, safe processing of the materials is illustrated and working times are reduced considerably. Work processes in the dental practice and laboratory are standardized.
Courses
bredent offers introductory courses and advanced level courses with a final test in the end. The courses for dental practices and dental laboratories are held separately. Impression taking and the proper fabrication of the models is demonstrated for the » practice. For the » laboratory, the course "Fabrication of a complex implant restoration" demonstrates the handling of the necessary materials and the principle of the material symbiosis.
