Recently, titanium mini screw implants have been utilized as the anchor for various orthodontic treatments. This method has several advantages such as a decrease in the treatment period, less discomfort for the patient, and reduced anchor loss which usually occurs among the natural anchor teeth. This method also has a number of problems such as the occurrence of disintegration, inflammation of the surrounding soft tissues, and screw fractures.
In this study 65 mini screw type implants applied in 26 patients were analyzed in terms of problems related to the location of the installation of the implants.
The following results were obtained: Problems were found in 17 implants (26.2%). The most frequent problem was inflammation around the implants (52.9%) in the maxillary posterior region. Fractures of the screw were also observed during the removable of screws; however, no screw fractures were found during the orthodontic treatment period.
These results suggest that further improvement in the installation method for mini screw type orthodontic implants are indicated.
