Second Class Resolver: a retrospective analysis.

Area of Science:

• Orthodontics
• Craniofacial Development
• Pediatric Dentistry

Background:

• Skeletal Class II malocclusion presents a significant challenge in pediatric dentistry.
• Effective treatment strategies are crucial for improving occlusal function and facial aesthetics.
• The Second Class Resolver (SCR) is a novel fixed orthopedic appliance introduced for Class II malocclusion correction.

Purpose of the Study:

• To evaluate the efficacy of the Second Class Resolver (SCR) in treating skeletal Class II malocclusion.
• To assess the orthopedic effects of the SCR appliance in growing subjects.
• To analyze cephalometric changes associated with SCR treatment.

Main Methods:

• Retrospective analysis of 40 growing subjects treated with the Second Class Resolver (SCR).
• Mean age at start of treatment was 8 years, and at end of treatment was 10 years.
• Digital cephalometric superimpositions on lateral radiographs were analyzed and statistically assessed.

Main Results:

• Significant reduction in ANB angle (mean 2°) and Witts Index (mean 3 mm).
• Reduction in Maxillo-Mandibular (MM) angle (mean 1°) and SNA angle (mean 3°).
• Increase in mandibular length (mean 5 mm) and mandibular body length (mean 2.9°), with a reduction in gonial angle (mean 1.8°).

Conclusions:

• The Second Class Resolver (SCR) is a beneficial appliance for treating skeletal Class II malocclusion.
• SCR treatment leads to favorable orthopedic changes in growing individuals.
• The appliance demonstrates effectiveness in correcting anteroposterior jaw discrepancies.
