The Dynamax system: a new orthopaedic appliance and case report

Area of Science:

• Orthodontics and Dentofacial Orthopedics
• Biomedical Engineering

Background:

• Skeletal II malocclusion, characterized by mandibular retrusion, presents a significant orthodontic challenge.
• Current treatment modalities often involve complex multi-stage interventions.

Observation:

• The Dynamax appliance is a two-part device designed for progressive mandibular advancement and maxillary expansion.
• It incorporates a prefabricated spring module, minimizing the need for extensive laboratory work and acrylic.
• The design facilitates clinical handling and patient comfort, with posterior lingual sulcus contact for stability.

Findings:

• The appliance allows for controlled maxillary growth, incisor torque, and vertical facial development.
• An adjustable spring module enables progressive mandibular advancement without a construction bite.
• The appliance is contained within the freeway space, with stable contact during mandibular opening and sleep.

Implications:

• The Dynamax appliance offers a simplified and potentially more acceptable treatment for Skeletal II malocclusion.
• It integrates orthopaedic correction with potential for simultaneous orthodontic treatment.
• This approach may enhance treatment efficiency and patient compliance in managing mandibular retrusion.
