CONELOG® Implant System Prosthetic Restorations - Camlog

PREPARATION
Abrasive wheels suitable for titanium machining are used for the preparation.
For fine preparation and to create the chamfer, we recommend finely
toothed titanium milling cutter. For grinding, the speeds recommended by
the respective manufacturer of the abrasive particles should be maintained.
Use only low pressure to avoid overheating the titanium. Overheating
causes a heavy «alpha-case» layer to form. It is very hard and can make further
processing difficult.
First, the abutment height and axial inclination are adapted, then followed
by preparation similar to standard chamfer preparation of a tooth stump
based on the perioprosthetics. The ideal preparation angle is approx. 2–4°.
For esthetic reasons, the crown margin should lie vestibular 1–1.5 mm subgingivally.
CAUTION!
To safely remove any remaining cement, the cement gap should not lie
deeper than 1.5–2.0 mm subgingivally for cemented restorations.
During the preparation process, we recommend to return the abutment into
the cast and use the silicone index to check the forming. At the conclusion
of the modification, the ground surface is smoothed (e.g. with a gumming
unit).

PROSTHETIC RESTORATIONS
TIP: To make later integration of the crown easier and to ensure antirotational
support, the preparation cross-section should not circular, but oval
similar to the root cross-section of the natural teeth and include a milled
conical guide groove.
TIP: To make orientation/alignment easier when inserting the abutment
into the mouth, a mark in the form of a milled depression on the vestibular
side can be attached. This mark is also transferred to the plaster cast and
makes handling on the cast easier in practice. This is particularly helpful
with several abutments.
