简要总结
| AIM OF THE STUDY**:** |
To compare and evaluate the amount of true intrusion and external apical root resorption achieved between mini-screws, utility arch and connecticut intrusion arch in the maxillary central incisors.
OBJECTIVE OF THE STUDY:
§ To evaluate the amount of intrusion in maxillary central incisors achieved with mini-screws, utility intrusion arch and connecticut intrusion arch.
§ To evaluate the amount of external apical root resorption in maxillary central incisors caused by mini-screws, utility intrusion arch and connecticut intrusion arch during intrusion.
§ To compare the amount of intrusion in maxillary central incisors achieved with mini-screws, utility intrusion arch and connecticut intrusion arch.
§ To compare the amount of external apical root resorption in maxillary central incisors caused by mini-screws, utility intrusion arch and connecticut intrusion arch during intrusion.
NULL HYPOTHESIS**:**
The amount of intrusion is same with mini-screws, utility intrusion arch and connecticut intrusion arch placed on the maxillary central incisors.
The amount of external apical root resorption is same with mini-screws, utility intrusion arch and connecticut intrusion arch placed on the maxillary central incisors.
