Terms & Conditions of Use

Area of Science:

Polymer Science
Biomaterials Engineering
Orthodontics

Background:

Orthodontic treatments often require appliances that can apply consistent force over time.
Traditional orthodontic wires may have limitations in terms of aesthetics and long-term force delivery.

Purpose of the Study:

To develop and evaluate a novel shape memory polymer wire for orthodontic applications.
To assess the shape recovery force and its durability for potential use in teeth alignment.

Main Methods:

Synthesized a polyurethane (PU) block copolymer via a two-step process.
Prepared the PU wire using melt-spinning.
Conducted orthodontic tests using a model with a metal bracket to evaluate shape recovery force.

Main Results:

The PU wire exhibited a high initial shape recovery force of 70 gf at 40 wt% hard segment content.
This force was maintained for up to 1 month at 50°C.
The force reached an equilibrium of 50 gf after approximately 20 days, sufficient for teeth correction.

Conclusions:

The shape memory PU wire is a promising novel orthodontic appliance.
Its high and sustained shape recovery force, coupled with aesthetic potential, supports its use in teeth alignment.
