“Shape Memory Effect + Thermoplastic” Dual-Engine
-- MOLEKUR™ Pro Neo Multilayer Product Launch
As clear aligners become the preferred choice for a growing number of patients seeking orthodontic treatment, material performance has emerged as the one of the core factors determining orthodontic efficacy and patient experience. From classic single-layer materials to today’s multi-layer composites, clear aligner materials have undergone continuous evolution—striving to achieve an optimal balance among mechanical properties, quality characteristics, and wearing comfort.
As an innovative company deeply rooted in the orthodontic material field, Coherz Technologies has always been driven by actual clinical needs. After multiple rounds of R&D and testing, we are proud to introduce a groundbreaking shape-memory thermoforming multi-layer material—MOLEKUR™ Pro Neo. This material overcomes the limitations of traditional options, integrating material science with clinical applications in an unprecedented way. While retaining the advantages of thermoplastic polymers, it also incorporates shape-memory effect that can be activated in final product application as aligners. Through innovative formula and design, it resolves the long-standing “trade-off dilemma” in the field.
Shape Memory Effect | Sustained Force Without Compromise
MOLEKUR™ Pro Neo is manufactured using special thermoplastic shape memory polymer (SMP) combined with a unique structural design. It not only preserves the superior mechanical properties and reliability of thermoplastic polymers but also features excellent shape memory characteristics that effectively compensate for the inherent stress relaxation of polymer materials.
Shape Memory Effect Test
After being worn for a period, aligners made from Pro Neo can be restored to their original shape through brief immersion in warm water. 3D scan image comparison shows that the overall accuracy loss after shape memory effect is no more than 2.2%. In particular, the front teeth—the area most prone to deformation— accuracy reaches as high as 99.8%, nearly identical to the initial aligner.
Aligner Accuracy before & after SME - 3D Scanning Image
Both initial force level and 24-hour stress relaxation closely match the original aligner state, enabling the material to achieve “active reset” and self-repair, thereby consistently delivering stable and effective orthodontic force.
Aligners Made of Pro Neo - Stress Relaxation Curve
Even after multiple times of shape memory recovery, aligners made of Pro Neo consistently return to their initial force level after thermal activated. This proves the reliability and effectiveness of its shape memory effect.
Initial Force Ratio of Aligners Made of Pro Neo after Shape Memory Recovery
The Shape Memory Effect (SME) of MOLEKUR™ Pro Neo not only allows the aligner to restore its optimal state, but also ensures stable, effective, and long-lasting force release. This supports effective tooth movement throughout entire treatment period.
Compared with other mainstream multi-layers, Pro Neo combines the features of thermoplastic polymers with the ability to overcome inherent stress relaxation. Even after extended wear, thermal activation can return the aligner to its ideal state—offering robust clinical support and assurance.
Resistance to Fatigue, Tear & Stain | Durable & Reliable
MOLEKUR™ Pro Neo demonstrates outstanding resistance to deformation and fatigue compared to mainstream multi-layer materials. Aligners made of Pro Neo provide the following advantages during long-term wear:
- Reduced risk of crazing and fracture
- Enhanced bending resistance
- Superior fatigue resistance
- Excellent stain resistance
These aligners are less likely to break or become damaged during daily use or frequent removal, offering reliability for patients and doctors.

Efficient Torque Control | Consistent and Effective Force Delivery
MOLEKUR™ Pro Neo features a relatively higher modulus than other multi-layer materials, enabling efficient torque control during treatment. In addition to its mechanical features, Pro Neo also offers a superior wearing experience—striking a balance between rigidity and flexibility for enhanced comfort.
Performance Summary | Four Core Advantages of MOLEKURTM Pro Neo
- Shape Memory Effect – Active stress recovery while retaining polymer material properties
- Resistance to Fatigue, Tear & Stain – High resistance to deformation and wear
- Comfortable Wearing – Balanced stiffness and softness for all-day comfort
- Sufficient force supply – Efficient torque control with sustained force
The launch of MOLEKUR™ Pro Neo represents not only Coherz’s innovation in aligner materials, but also a direct response to the industry’s need to balance efficacy and experience. It redefines the potential of thermoforming aligner material, offering customers a more reliable option and elevating the standard of orthodontic care.
In the future, Coherz Technologies will remain committed to our mission: “Cohering talents of creativity, promoting dental healthcare.” We will continue to deepen the integration of material R&D and clinical applications, introducing ever more innovative clear aligner solutions that meet customer needs and industry trends.
We look forward to collaborating with global partners to drive progress in dental health and empower confident smiles through technology.
