The very first in the world

A revolution in

dental implant systems.

 

SYLBUTMENT is the product of engineering research in which the perfect contact of two flat surfaces

is only possible theoretically but practically impossible. 

Unprecedented - a remarkable sealing effect

The Sealing Effect occurs because of elastic modifcation done by the pressure on the circular bands of the contact sides. 

 

Outstanding durability due to even stress distribution

The even contact surfaces uniformly transfer power from prosthetic appliances to fixtures. Results of fatigue tests showed that not a single fatigue failure occurred when repeated high stress loads were applied.

NO Gap

The circular bands act as a cushion within the limits of elastic modifcation when chewing force is applied.

NO Loosening

The even surface contact of the circular grooved pattern evenly distributes chewing force within the limits of elasticity, preventing the screw from loosening and the abutment from swaying. 

The principles of 

The principles of SYLBUTMENT are easily discovered around us.  

Conventional Abutment and 

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 flat surfaces is only possible theoretically but practically impossible. 

The reason why                                is strong against fatigue (1) 

When the abutment screw is fastened, elastic deformation occurs around the grooves of the SYLBUTMENT, creating a force which moves the abutment and fixture together. 

Pressure distribution at the contact surfaces of the Fixtures and the Abutments (FEM Analysis) 

When conventional abutments experience asymmetrical chewing forces, the contact surfaces of the fixtures and abutments are separated; however, when a SYLBUTMENT is used, the contact surfaces are not separated. 

The reason why                                is strong against fatigue (2) 

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 fixture. 

Fatigue tests of the 

Conventional Abutments can withstand 5 million repeated loads of 344N~34N, but the SYLBUTMENT can withstand 5 million repeated loads of 552N~55N.
