FEATURE OF ABSOANCHOR
Clinicians continue to need anchorage that displays a high resistance to displacement.
However, Newton's Third Law that posits a reaction for every action makes this
difficult to achieve intraorally. Earlier, orthodontists used extraoral traction to reinforce
intraoral anchorage. Nevertheless, patients seldom used headgears 24 hours a days a
Week, so this source of anchorage was often compromised.
The ideal intraoral anchorage would
not displace, which would require a source
Without a periodontal membrane that responds to tension and pressure and allows
movement through bone.
Recental prosthetic osseointegrated implant have been used
as intraoral orthodontic anchorage, but their size, bulk, cost and invasiveness have
limited their orthodontic application.
Some have used ordinary bone screws along with bone plates to provide intraoral
anchorage, but the screw heads failed to protect the gingiva from the impingement of
ligatures or attached elastic forces.
These became a source of constant gingival irritation and inflammation, which limited
the usefulness of this type of implant. The design of the screw heads also made it
difficult to connect coil springs and orthodontic forces to these ordinary bone screws.

So we developed small diameter titanium microimplant, Absoancher (Absoanchor,
Dentos Inc. Taegu city, korea), Which has been designed specifically for orthodontic
use and has a button-like head with a small hole that accepts ligatures and
elastomers(Fig. 2). the Absoanchor's small diameter of microimplant allows its insertion
in to many areas of the maxilla and mandible previously unavailable, e. g., between the
roots of adjacent teeth.
