Titanium Microscrew Implant의 고정원으로서의 이용

Abstract

The purpose of this is to evaluate the efficacy of the skeletal cortical anchorage using titanium microscrew implants, and to describe the clinical considerations. Author examined 14 patients, who had been treated orthodontically by skeletal cortical anchorage. The 23 of 28 titanium microscrew implants, implanted on the upper and lower alveolar bones, had remained firm and stable for 5 months orthodontic force application. The cause of 5 failed microscrew implants was excessive force during manipulation. So, if the problem concerning excessive force solve, the success rate will increase. The most outstanding results were 1-2 mm posterior movement of the posterior teeth during months orthodontic force application in 6 superimposed cases, which were usually act as anchorage during conventional orthodontic treatment. Conclusively the skeletal cortical anchorage using titanium microscrew implants night be excellent method of anchorage control in maximum anchorage case in the orthodontic treatment.
