In this case, a superstructure is to be retained with a
screw. The abutment should be waxed up using standard
procedures.
Once the abutment has been cast, it should be milled and
polished.
A centering drill is used to create a dimple in the
correct position.
The correct size of Multidrill is used to drill a hole
at the correct angle for the threaded rod. It is
essential that Bredent’s milling and drilling oil (#550
000 08) is used.
Screw the threaded rod into the sleeve. Both the pin and
the hexagonal socket can be reduced as required.
Coat the threaded rod and sleeve with Piku-Plast resin
(#540 001 76).
Piku-Plast guarantees optimum strength for continued
processing.
Screw a retention screw coated with colloidal graphite
into the threaded sleeve to retain it in the investment
material (#540 007 06).
The rear of the short screwdriver can be used to remove
the retention screw.
Security Lock screws (thread sizes): Size 1.0 = M2 = 2.0 mm Size 1.4 = M2 = 2.0 mm Size 1.8 = M2.5 = 2.5 mm Total lengths of the threaded sleeves: Size 1.0 = 5.3 mm Size 1.4 = 5.3 mm Size 1.8 = 5.3 mm Reducibility of the threaded sleeves: Note: The threaded sleeves can
only be shortened at the non-threaded end. If it is shortened at the
other end, no guarantee of faultless function can be given. Size 1.0 = 2.3 mm Size 1.4 = 2.3 mm Size 1.8 = 2.3 mm Rest length of the threaded sleeved = Minimum
thickness of the secondary part! Size 1.0 = 3.0 mm Size 1.4 = 3.0 mm Size 1.8 = 3.0 mm Outside diameter of the threaded sleeve: Size 1.0 = 2.8 mm Size 1.4 = 2.8 mm Size 1.8 = 3.2 mm Diameter of the retention rods for the
Security Lock: Size 1.0 = 1.0 mm Size 1.4 = 1.4 mm Size 1.8 = 1.8 mm Retention rod lengths: Size 1.0 = 3.0 mm Size 1.4 = 3.0 mm Size 1.8 = 3.0 mm Reducibility of the retention rods: The retention rods can be individually
shortened. The rest of the retention rod should be sufficient so that a
solid lock can be attained.
