Manufacturer "dentona"

dentona

Numerous innovations for dental model fabrication have characterised dentona for decades. Our dental research findings are translated into high-quality speciality products for dental laboratories. For dental plasters from dentona, special plasters are produced from selected raw materials in standardised processes with material tests that go far beyond the DIN requirements in order to guarantee the promised product properties of the dental plasters. After decades of producing the dental speciality plasters, the production of our own silicones was the logical consequence in order to meet the ever-increasing demands of dental laboratories for processing quality and physical properties with consistent quality. Dental model systems are optimised for dental laboratories by the innovative plastic base system from dentona with a further developed connection technique between split cast plates and base plates. The high-quality special investment materials for crown and bridge as well as model casting techniques fulfil the highest requirements for rapid casting techniques as well as conventional heating techniques and round off the dental casting technique with the dentona abrasive.
