Abstract
Aims: To evaluate the rates of success and failure regarding
the mobility of orthodontic microimplants in patients
undergoing fixed orthodontic appliance treatment. Materials
and Methods: The sample consisted of 36 titanium
microimplants (AbsoAnchor®, Dentos inc. Korea) inserted in
15 female patients. The mean age for the patients was 25.53
years. Microimplants of 1.2 mm in diameter and 6–10 mm in
length were used. A self–drilling method was used. A small
vertical stab incision and the microimplants inserted with a
screwdriver. The patients were seen periodically every 3–4
weeks. A microimplant with complete absence of a clinically
detectable mobility was considered as a successful one.
Whereas failure was defined as a microimplant mobility
within 8 months. Results and Discussion: The total success
rate for microimplants for both jaws was (86.1%). Whereas a
(91.7%) success rate was recorded in the upper jaw and in the
lower jaw it was (75%).Despite of higher failure rates in the
mandible, which may be attributed to the occlusal force, yet
they remain non significantly different from those in maxilla.
Conclusions: The relatively high success rates of
microimplants make them an appropriate solution for
providing absolute anchorage whenever being needed in
orthodontic therapy. _x0001_
