The abutment and crown are an integrated unit without the use of cement.
SCD produce implant-retained restorations with either original or genuine components of implant systems or by using cutting-edge milling technology to fabricate custom components.
These are waxed up, cast and have veneering porcelain or ceramic-composite hybrids applied. A casting alloy is used, which is compatible with the castable base.
Titanium bases are manufactured using CAD/CAM techniques and used as adhesive
bases for individual implant-supported reconstructions. Restorations on titanium
bases can be made of either monolithic or laminated zirconium-oxide ceramics,
lithium disilicate or ceramic-composite hybrids and ensure a high-precision fit to the
implant.
Angulated screw channel technology allows placement of the screw access hole
anywhere between 0° to 25° from the axis of the implant screw channel, improving
access and enabling cement-free and more aesthetic outcomes.
The materials commonly used are titanium, zirconia or cobalt chromium.
Zirconia abutments are highly aesthetic. Alloy abutments are stronger than zirconia
abutments.
Cobalt chromium is a popular material for PFM screw-retained units as porcelain
bonds more predictably to the alloy. In large-span and heavy load-bearing cases,
alloys are the preferred option compared with zirconia.
