Introduction Designed by a collaboration of the worlds leading technicians and academicians, Trio posterior denture teeth set a new standard in denture fabrication. Trio posterior denture teeth are available in both lingual and semi-anatomic occlusal schemes for patient specific occlusion. Trio posterior teeth are designed to be used with the Stratos® articulation system. This system includes a complete line of precision articulators and setup guides to ensure accurate and predictable setups.
Cast Analysis Prior to setup it is important to conduct a basic cast analysis to ensure the proper placement of the Trio posterior teeth.

Trio DCL – Setup Manual Indications – Trio posterior denture teeth are indicated for use in the fabrication of complete and partial dentures where applicable.
– SR Triotyp DCL features a semi-anatomic occlusal scheme, and can be used in complete and partial dentures where applicable. Use the corresponding upper SR Orthotyp® DCL posterior denture teeth when opposing a Trio setup.
– SR Triolingual DCL should be used when lingualized occlusion has been prescribed or is best suited for the patient. Use upper SR Ortholingual® DCL posterior denture teeth when opposing a Trio setup.
An own setup method – PARALLEL from that of BPS® – according to this Manual is available for Trio teeth. After tooth setup protusive and lateral movement shoould be checked.

Trio Template Setup
1. Prior to setting the SR Trio DCL posterior teeth set the maxillary anterior denture teeth on the Stratos®. The Trio teeth settingup template will provide verification of bilateral symmetry and the midline.
