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.
