Clinical factors correlated with the success rate of miniscrews in orthodontic treatment

Abstract

Two researchers in Greece have identified reasons why ‘miniscrew’ dental implants may succeed or fail. They monitored 34 patients with a total of 82 miniscrews implanted in their mouths, and analyzed the factors that might contribute to miniscrews becoming infected or dislodged. They found that the length and diameter of the miniscrews, the site and method of miniscrew placement and, most importantly, the number of miniscrews implanted, showed significant correlations with success rates. Overall, the miniscrews had a success rate of 90.2%. Miniscrews are the preferred method of anchorage for many dental procedures, as they avoid the social stigma of external devices such as headgear, or the expensive surgery involved in osseo‐integration, where implants make direct functional connections to bone.
