Abstract
OBJECTIVES:
The purpose of the study is:
To evaluate the dental and skeletal changes of Advansync 2 appliance.
To evaluate the soft tissue changes of Advansync 2 appliance using photometric analysis.
METHODS:
The sample size consisted of 15 patients who reported to Department Of Orthodontics, seeking fixed orthodontic treatment. The effects of Advansync 2 appliance were measured at two intervals.
RESULTS:
After the nine months, P-values were observed to be less than 0.5, therefore statistically significant for parameters such as SNA, CO-A, WITZ, C0-Gn, ANB, UI-A (degree), LI-B (mm), LL-E plane, Nasolabial angle, Mentolabial angle, Facial angle and L lip to chin. P-value were however observed to be greater than 0.5, therefore statistically insignificant for parameters such as SNB, C0-Go , UI A(mm), LI B(mm),UL-EPL,H LINE, FMA, Nose tip angle, Nasofrontal angle, Nasomental angle, Upper lip angle and U lip to chin.
CONCLUSIONS:
AdvanSync 2 appliance brought about a change in Class II malocclusions through Co-Gn, Co-Go, ANB, FMA, UI-A (degree), UI A (linear) LI B (linear), UL-E plane, LL-E plane, H LINE, Nose tip angle, Nasolabial angle, Mentolabial angle, Nasofrontal angle, Nasomental angle, Facial angle, Upper lip angle, U lip to chin, L lip to chin after nine months of appliance delivery.
MAIN POINTS:
Advansync 2 normalised class II by increase in length and body of mandible.
Advansync 2 has a restraining effect on the growth of maxilla.
Advansync 2 brings about positive soft tissue changes.
