PLLA Cones Cog (Fish Bone) Thread 18G / 19G 100mm: Press-Sculpted Heavy Lifting Thread

Deenora Thread is a one-stop supply platform for aesthetic medicine products, and threads are our core product line. The PLLA Cones Cog, also known as the fish bone thread, is one of the strongest lifting threads in our range: a USP3 PLLA thread with a dense row of cone-shaped cogs, press-sculpted rather than cut, on a high-quality blunt cannula.

Key features

Press sculpting method: the cones are formed by compression moulding, so they are part of the thread body instead of being cut into it. This keeps the cogs intact and the filament strong under tension.
Highly effective lift: closely spaced cones along a 160 mm thread grip tissue over a long vector for powerful suspension of heavier tissue.
Long-lasting thread: the thick USP3 PLLA body is absorbed gradually and supports ongoing collagen stimulation along the thread track.
High-quality cannula: blunt-tip cannula for smooth advancement with less trauma to vessels and nerves.

Choosing a model

L Cannula vs W Cannula. Both are blunt-tip cannulas carrying the same thread. The L cannula is the standard choice for most practitioners; the W cannula offers an alternative tip design for those who prefer its handling and thread release. Clinics usually standardise on the cannula their team is trained on.

18G vs 19G. 18G is the more rigid option, giving firmer control when pushing through thicker, heavier tissue on the jowls, lower face and neck. 19G is slightly finer, suited to practitioners who want a less traumatic entry and more flexibility in the midface and cheek vectors.

Typical indications

Jawline and jowl lifting, midface and cheek repositioning, deep nasolabial and marionette support, and neck lifting, where a strong, long-vector suspension thread is needed. Final vector design and thread count are determined by the treating practitioner.

FAQ

What is a fish bone thread?

A cog thread with a continuous row of cone-shaped barbs resembling a fish bone. The cones anchor tissue along the full length for strong lifting.

How is this different from a molding thread?

Both are moulded rather than cut. The cones cog uses a thicker USP3 thread and a longer 160 mm length for heavier, longer-vector lifting.

18G or 19G?

18G for thicker, heavier tissue and firmer control; 19G for a finer entry in the midface.
