The internal Hex Tube and Screw is used for vertical screw retention of crowns and bridges, dentist-only removable fixed prosthesis, implant suprastructures, fixed complete (hybrid) dentures, and telescopic prostheses.
Easy to use. Prethreaded tubes for casting, soldering, or bonding to cast primary units.
Versatile. Multiple sizes of 1.20mm and 1.40mm diameter. Short and long available in each diameter. Same Hex used for
Pin Screw and Tube and Screw systems.
Accurate. End cutting bur provides for accurate sizing and finishing of cast collar.
Tube & Screw
The hex screw is a high fusing precious alloy. It can be shortened as needed, as long as the hex profile is maintained. The countersunk collar is a non-oxidizing, high fusing precious alloy. The conical hex screw perfectly fits the countersunk collar, efficiently distributing forces and creating a hygienic seal on the occlusal surface.
The sleeve is also a high fusing precious alloy, and the fixation screw holds the sleeve in place during casting, reducing the risk of molten alloy flowing into it.
Always use the largest and longest screw for the space available. The bonding technique for the tube is the most accurate method of incorporation.
Complete Tube and Screw Attachment
Includes Tube, countersunk Collar, Fixation screw, and final Hex screw.
Four different options:
- 1.2mm Short
- 1.2mm Long
- 1.4mm Short
- 1.4mm Long
The fixation screw can be destroyed at temperatures above 1400 °C and by excessive overheating of the casting alloy.
