Abstract

To provide some guideline for microscrew implants, 73 patients that received a total of 180 mini- or microscrew implants were scrutinized. The overall success rate was $93.3\%$ (168 among 180 mini- or microscrew implants) and the mean period of utilization was 15.8 months. Microscrew implants in the UB group (maxillary buccal area) succeeded at a rate of $94.6\%$ (87 among 92), mini- or microscrew implants in the LB group (mandibular buccal area) succeeded $96.6\%$ of the time (56 out of 58), while microscrew implants in the UP group (maxillary palatal area) had a $100\%$ success rate (11 out of 11), and mini- or microscrew implants in the LR group (retromolar area) succeeded in $73.7\%$ of cases (14 among 19). This study might indicate that microscrew implants can be used successfully as orthodontic anchorage in daily orthodontic practice.

치아이동의 고정원으로 사용되고 있는 miniscrew and microscrew implants의 임상 적용의 유용성을 알아보고자 73명의 환자에 식립된 180개를 대상으로 성공율을 연구하였다. 1년 기간의 전반적인 성공율은 $93.3\%$(180개의 miniscrew and microscrew implants중 168개 성공)이었고, UB군(상악 헙측치조골)은 $96.6\%$(92개중 87개 성공), LB군(하악 혐측치조골)은 $96.6\%$(58개중 56개 성공), UP군(상악 구개측 치조골)은 11개중 11개가 모두 성공하여 $100\%$를 보였고, LR군(하악 후구치 부위)은 19개중 14개가 성공하여 $73.3\%$의 성공율을 보였다. 이 연구를 통하여 볼 때 miniscrew and microscrew implants는 교정치료의 고정원으로 성공적으로 사용될 수 있을 것으로 생각된다.
