Impact of Sagittal Guidance vs Twin-Lock Twin-Block Device on Alveolar Bone Near Lower Incisors in Adolescents Having Class II Div 1 Malocclusion.

Abstract

Aim: This research aimed to evaluate the effects of modified Sagittal-guidance twin-block (SGTB) appliance on class II skeletal and dental alterations among developing pt.

Methodology: A total of 25 adolescent adults in class II div 1 made up the sample, which split equally between the twin-block (TB) and SGTB groups. The course therapy lasted 11.56 ± 1.73 months.

Results: There was no discernible distinction between T1 and T2 in terms of lingual bone height, lingual and overall dental bony volume, and whole alveolar bone width (P < 0.05).

Conclusion: In maturing children having class II div 1, labial bone decrease surrounding the mandibular incisors was noted following intervention with the two kinds of prostheses.
