Orthodontic micro implants, also known as mini implants, are temporary anchorage devices made of biocompatible metal (usually titanium alloy). They measure approximately 1–2 mm in diameter and 6–12 mm in length and are inserted into the jawbone during orthodontic treatment. Their primary role is to serve as a stable anchorage point for applying precise forces to move teeth.
Provide stable anchorage for single-tooth or group tooth movements
Correct complex malocclusions without bulky external appliances
Accelerate tooth movement by minimizing unwanted reciprocal forces
Allow three-dimensional control of forces (vertical, horizontal, and rotational)
Reduced reliance on patient compliance compared to headgear or elastics
Easy placement and removal in the office without major surgery
Ability to withstand higher forces with minimal displacement
Low risk of damage to root surfaces or soft tissues when protocol is followed
Maintain excellent oral hygiene and use chlorhexidine rinse in the initial days
Have regular check-ups to monitor implant stability and surrounding tissues
Avoid applying excessive force outside the prescribed directions
Typical retention time ranges from 3 to 12 months, depending on treatment objectives
