The Morelli Titanium Bracket Head Counterclockwise Self-Drilling Mini Implant is a temporary anchorage device (TAD) for interradicular placement. Its bracket head carries two .021″ × .025″ (0,53 × 0,63 mm) slots perpendicular to each other plus a round hole that anchors accessories up to Ø0,8 mm. It is driven counterclockwise, on a left-hand thread, and is identified by its blue head.
Key Features
Counterclockwise insertion, blue head — left-hand thread with a blue anodized head, so the insertion direction is identified at a glance chairside
Direction chosen by the mechanics — plan the placement so the orthodontic wire mechanics tend to tighten rather than unscrew the mini implant, and observe the removal direction so it is not driven deeper
Bracket head with two perpendicular slots — .021″ × .025″ (0,53 × 0,63 mm) each, dimensioned to accommodate rectangular wires precisely
Round accessory hole — anchors elastic chains, coil springs and ligatures up to Ø0,8 mm directly in the head, so wire and elastic mechanics can be combined on the same implant
Titanium F136 alloy — medical-grade Ti-6Al-4V, the reference material for temporary skeletal anchorage devices
Slim Ø1,5 mm body — with a 1 mm transmucosal section, sized for placement between the roots
Self-drilling active tip — profile designed for stability, a secure fit in the bone texture and resistance for immediate orthodontic load

Clinical Applications
Interradicular skeletal anchorage on the side of the arch where the traction would tend to unscrew a right-hand thread, keeping a minimum clearance of 1 mm from the adjacent roots
Rectangular wire mechanics engaged in either of the two perpendicular head slots, chosen by the plane of force required
Immediate-load mechanics applied perpendicular to the long axis of the mini implant and within the 300 gf limit, using cantilevers, chains or springs
Which way will the traction turn the screw?
This device is driven counterclockwise (left-hand thread) and carries a blue head: position it so the traction of your mechanics tends to tighten the screw rather than loosen it, respect the 25 N.cm maximum insertion torque and the 300 gf force limit, and reverse the driving direction carefully on removal.
