Precision-engineered for complex orthodontics

The 7+3 system uses two complementary aligner materials within a single treatment sequence. masterControl S™ aligners are worn for 7 days each, applying gentle, self-adaptive force to initiate each planned tooth movement. masterControl™ aligners follow for 3 days, applying a more precise and effective force to complete the movement efficiently. This staged delivery reduces peak force at the most sensitive point in the movement cycle, improving patient comfort and compliance while maintaining — or exceeding — the efficiency of single-material systems. The architecture also gives the orthodontist greater control over the number of stages required, which can reduce overall treatment length and refinements.

Angel Aligner Pro is designed for orthodontists treating moderate to complex adult malocclusions — including crowding, spacing, deep bite, open bite, crossbite, and cases presenting with significant overjet. Through the A6, A7, and A8 technical solutions, Pro also supports mandibular advancement, premolar extraction, and molar distalization cases. Suitability is always determined by the treating orthodontist following clinical assessment, and the iOrtho™ platform provides the tools to evaluate and plan even complex presentations digitally before production.

The Intelligent Root System integrates CBCT data into the iOrtho™ treatment planning environment, making root position — not just crown position — visible at every planned stage of treatment. This matters clinically in cases involving bodily tooth movement, root torque, or proximity to adjacent roots or cortical bone. By visualising the full root trajectory throughout the planned sequence, the treating orthodontist can refine the treatment plan before any aligners are produced, reducing the risk of iatrogenic root resorption and improving overall precision.

Conventional elastic mechanics in clear aligner treatment require separate composite buttons bonded directly to the tooth surface — a process that adds bonding appointments, creates potential for debonding events, and can cause mucosal irritation. angelButton™ eliminates the need for a separate bonded element: the button is integrated into the aligner body itself as part of the manufacturing process. This reduces the number of clinical appointments required during the elastic-wear phase, lowers the risk of debonding complications, and removes a source of patient discomfort. It is the world's first such integration in a clear aligner system.

Yes. Angel Aligner Pro includes up to three retainers as part of the treatment plan. When a patient requires a replacement retainer — due to loss, wear, or dimensional change — it can be reordered through the iOrtho™ platform without requiring a new intraoral scan. This significantly simplifies the long-term retention phase for both the practice and the patient, removing a common friction point in the post-treatment experience.

Once a case is submitted through iOrtho™ with complete clinical records, a 3D treatment plan is prepared and returned to the treating orthodontist within T+3 working days. Following orthodontist approval, aligners are produced and delivered within T+5 working days. This turnaround is maintained across all Pro cases and forms part of Angel Aligner's service commitment to its network of over 25,000 dental professionals.

From the patient's perspective, the key differences are comfort and discretion. The masterControl S™ phase of each 7+3 cycle begins with a gentle force application, which typically means less soreness in the first days after each tray change — a common point of discomfort with standard aligner systems. The aligners are nearly invisible when worn and are fully removable for eating, drinking, and oral hygiene. The angelButton™ integration, where elastic mechanics are required, removes the need for visible bonded buttons on the tooth surface, further supporting aesthetics during treatment.
