An evaluation of dentofacial changes in Angle's class II division 1 patients using AdvanSync 2

Area of Science:

• Orthodontics
• Dentofacial Orthopedics
• Cephalometric Analysis
• Photometric Analysis

Background:

• Class II malocclusion presents complex skeletal and dental challenges.
• Effective orthodontic appliances are crucial for correcting these discrepancies.
• The AdvanSync 2 appliance is a novel device for Class II correction.

Purpose of the Study:

• To evaluate dental and skeletal changes induced by the AdvanSync 2 appliance.
• To assess soft tissue alterations using photometric analysis following AdvanSync 2 treatment.

Main Methods:

• A sample of 15 patients undergoing fixed orthodontic treatment was selected.
• Dental, skeletal, and soft tissue changes were measured at two intervals.
• Statistical analysis (p-values) was used to determine significance of changes.

Main Results:

• Statistically significant changes (p < 0.5) were observed in parameters like SNA, CO-A, C0-Gn, ANB, UI-A (degree), LL-E plane, nasolabial angle, and facial angle.
• Insignificant changes (p > 0.5) were noted for SNB, C0-Go, UI A (mm), FMA, and several other soft tissue parameters.
• The AdvanSync 2 appliance promoted mandibular growth and restricted maxillary development, leading to normalized Class II occlusion and positive soft tissue changes.

Conclusions:

• The AdvanSync 2 appliance effectively corrected Class II malocclusions through significant skeletal and dental modifications.
• Positive soft tissue profile changes were achieved, enhancing facial aesthetics.
• A notable disadvantage was the proclination of lower incisors.
