Gedetailleerde beschrijving
Researchers will evaluate the influence of mini-screw length, diameter, oral hygiene status, age, sex, and loading time on the failure rate of infra-zygomatic mini-screws. Mini-screw failure will be assessed clinically by the presence of mobility or loss of stability.
Participants will:
- Receive fixed orthodontic treatment with a pre-adjusted edgewise appliance system.
- Receive infra-zygomatic mini-screws bilaterally for maxillary anchorage reinforcement.
- Receive a 10 mm × 1.8 mm mini-screw on one side with immediate loading.
- Receive a 12 mm × 2.0 mm mini-screw on the contralateral side with delayed loading.
- Receive standardized orthodontic force using elastic power chain.
- Undergo CBCT assessment to evaluate the position of the inserted mini-screws.
- Be evaluated at baseline and at one-month intervals for three consecutive months to assess mini-screw mobility or failure.

This is a split-mouth randomized clinical study in which each participant will receive infra-zygomatic mini-screws bilaterally.
One side will receive a 10 mm × 1.8 mm mini-screw with immediate loading, while the contralateral side will receive a 12 mm × 2.0 mm mini-screw with delayed loading.
The failure rate will be assessed clinically over a three-month follow-up period.Mini-screw failure will be assessed clinically by the presence of mobility or loss of stability.

This randomized clinical study will assess the factors associated with the failure rate of infra-zygomatic crest orthodontic mini-screws used for anchorage reinforcement during orthodontic treatment. Researchers will evaluate the influence of mini-screw length, diameter, oral hygiene status, age, sex, and loading time on the failure rate of infra-zygomatic mini-screws. Mini-screw failure will be assessed clinically by the presence of mobility or loss of stability. Participants will receive:
