Cap Screw (Tube and Screw), 1.2mm diam. long

1. Is there a connector in doing milled work?
Yes, the Tube and Screw which rigidly connects primary and secondary telescoping castings can be used.

2. What is the biggest problem with the Tube and Screw?
Insufficient space for the attachment. The Tube and Screw requires both a primary and a covering secondary casting. The tube cannot be shortened.

3. Is its use limited to tooth borne crown and bridge?
No, it allows a bridge to be segmented into two or more sections, each with its own line of draw, yet to be a single rigid structure in the mouth. It can often provide a neat solution to non-parallel abutments and can even create a dentist removeable pontic for easier periodontal maintenance of the case. It can also be used in conjunction with a UCLA abutment on implants to create a custom, screw retained, abutment when the implant diverges far from the case's path of insertion.

4. What sizes are available?
There is quite a range of sizes available to suit each individual need such as:
Tube and Screw 1.0mm-1.4mm short/long
Screw 1.0mm-1.4mm short/long
Tube 1.0mm-1.4mm short/long
Collar 1.0mm-1.4mm

case designs which accommodate non-parallel abutments, and implant restoration.
Gold alloy tube (Ceramicor), collar (Ceramicor), and screw (OSV).
Rigidly connects primary and secondary telescoping castings.
Fixation:
Tube - fixed component, cast to with most precious alloys.
Collar - removable component, cast to with most precious alloys.
Screw connections are used in dentist removable fixed partial dentures,
The threaded tube is in the cemented primary casting. The collar is in the removable secondary casting and provides a precision seat for the head of the screw. The screw holds the primary and secondary castings together.
