Conventional Abutment and sylbutment
The principles of
The principles of SYLBUTMENT are easily discovered around us.
In a conventional abutment, the gap between fixture and abutment may increase gradually due to repeated chewing forces. This is due to the contact between the outer surface
of the abutment and the inner taper of the fixture, which only occurs on a small surface
area due to the roughness of both the two surfaces. On the other hand, SYLBUTMENT
increases the contact surfaces by transformation to the grooves. It does not create a gap
as the transformation between the two surfaces occurs within the elastic range.
Why does loosening occur in conventional abutments?
The perfect contact of two at surfaces is only possible theoretically but practically impossible.
The perfect contact of two at surfaces is only possible
theoretically but practically impossible.
When a chewing force is applied then removed,
the gap between the two surfaces increase.
As shown in the figure above, chewing forces are experienced asymmetrically
due to the grooves of the SYLBUTMENT acting as an elastic body. This firmly
maintains the sealed state of the abutment and distributes the chewing forces
evenly in the fxture
