The MARS appliance. Report of a case

Area of Science:

• Orthodontics
• Biomaterials Engineering
• Dental Device Design

Background:

• Patient compliance with functional appliances, elastics, and headgear for Class II malocclusions is a significant clinical challenge.
• Existing treatments often rely on patient cooperation, leading to inconsistent results.
• The need for a fixed functional appliance that minimizes reliance on patient compliance is critical.

Observation:

• The Mandibular Advancing Repositioning Splint (MARS) is a novel fixed functional appliance.
• It attaches to existing orthodontic archwires, integrating seamlessly with multibanded appliances.
• The MARS appliance utilizes a piston-cylinder mechanism to maintain mandibular protrusion while allowing full jaw movement.

Findings:

• The MARS appliance enforces continuous mandibular repositioning, addressing cooperation deficiencies.
• Clinical observations indicate encouraging results in a pilot study for Class II malocclusion treatment.
• The device facilitates 24-hour protrusive positioning without hindering mastication or excursive movements.

Implications:

• The MARS appliance offers a potential solution to improve treatment outcomes in Class II malocclusions by enhancing patient compliance.
• This fixed functional device may reduce treatment duration and variability associated with removable appliances.
• Further research and larger clinical trials are warranted to validate the efficacy and long-term effects of the MARS appliance.
