Angelalign Introduces SuperElastic Material

The newly refined clear-aligner material gives orthodontists greater control

SAN CLEMENTE, Calif. — Angelalign Technology Inc. (6699.HK) (“Angel”), a global leader in clear aligners, today introduced SuperElastic (MC-SE*), a new proprietary aligner material that represents a significant performance advance over the materials it currently uses.

Orthodontic specialists have long sought a new aligner material that can better support the treatment of complex cases, combining biologically safe force levels, a broad elastic working range, strength and toughness. MC-SE is designed to deliver all these qualities.

“Angel is committed to innovation and is never satisfied with ‘good enough’. MC-SE is the result of seven years of materials research, testing and manufacturing-process optimisation. This new material aims to provide a next-generation aligner material, enabling orthodontists to offer superior treatment,” said Fox Hu, Angel’s chief executive.

MC-SE will be available worldwide after the necessary regulatory approvals have been obtained.

A new material for complex cases

Clear-aligner materials determine how consistently force is applied to the teeth, how well an aligner maintains its shape during use, and how comfortable it is for patients.

Angel’s current material is a soft, multilayer polymer based on PETG, designed to deliver sustained light force. MC-SE uses a different material and offers several significant improvements:

• Light, consistent force: designed to deliver continuous force at biologically safe levels throughout the period of wear.

• A broader elastic range: it can be bent and stretched more than conventional materials, then return to its original shape, potentially enabling new clinical approaches.

• Superior elastic recovery: in a three-point bending test at eight per cent strain, MC-SE returned to its original flat shape. By contrast, samples of commonly used PETG and Angel’s current material retained visible bends.

• Structural strength and toughness: a medical-grade polyamide layer in MC-SE’s multilayer structure adds strength and toughness.

Inspired by orthodontics’ clinical tradition

Nickel-titanium (NiTi) archwires are valued by orthodontists for their ability to deliver continuous light force and are a standard treatment in braces and brackets. Angel said it was proud to continue this tradition by introducing MC-SE, which brings similar characteristics to clear aligners.

The performance advance was achieved by integrating medical-grade polyamide into the aligner material. Polyamides, a material group that includes Kevlar and nylon, are used in demanding applications requiring elasticity, strength and toughness. MC-SE incorporates these characteristics into an innovative aligner material.

Aligners made with medical-grade polyamide could open up promising treatment possibilities. Angel plans to develop the technology as a materials platform, with different variants designed to produce a range of force effects.

“Angel’s innovation is based on feedback from orthodontists and analysis of treatment-case outcomes. Clinicians send us many complex cases,” said Richard Hirschland, Angel’s chief commercial officer and senior vice-president. “Aligner material is the foundation of every treatment. MC-SE gives orthodontists a stronger foundation. This launch follows angelButton™, A6 Mandibular Advancement and Pressure Points, as part of our commitment to continually developing clinical solutions for orthodontists.”
