CORTICALIZATION WITH KOS IMPLANTS

Compression screw Implants (KOS)  are not considered to be Basal Implants. 



In conical Implants high insertion torques concentrate on the flat or rounded  apex area, whereas pressure distributes evenly over the whole vertical Implant area in conical implants and not in the apex of the Implants.
This pressure distribution is EFFECTIVE.

Furthermore spongeous bone becomes condensed whenever compression screw implants are inserted.
The process of condensing is described as CORTICALIZATION.

During this corticalization, the flow through the osteons is cut off, osteons are destroyed and compressed and they can no longer be the source of osteonal remodelling but only the target of osteons travelling from unaffected bone areas.

Since this takes more time( depending on the distance from the point of the initiation of a secondary osteon to the Implant surface), the time-span for carrying out prosthetical work on KOS Implants is increased.

Nevrthless, Immediate splinting( and therby loading) is still the safest way of handling KOS and BCS Implants.
