Abstract

Introduction: The essential determinant for facial aesthetics is an understanding of the relationship between the facial bones and soft tissue. A proportionate relationship among the different structures of a face is the key to its aesthetic and pleasing appearance. The facial profile is determined by the facial soft tissue thickness (FSTT) and dental and skeletal characteristics. Face contours are traditionally considered to be a result of the position of basic hard dental and skeletal tissues followed by the soft tissue.

Objective: To correlate the hard and soft tissue in different skeletal malocclusion.

Methodology: A descriptive cross-sectional study was conducted from 2023 September to 2024 May after ethical approval. Convenient sampling method was used to collect 105 samples who were divided into three groups I, Class II, Class III. Patients aged 18-30 years were included in this study. Patients undergoing orthodontic treatment and with no craniofacial deformities were included in the study. Statistical analysis was performed using IBM SPSS Statistics for Windows, version 21 (IBM Corp., Armonk, N.Y., USA).

Result: In this study, in hard tissue parameter, mean value of LI to A-pog, UI to PP plane, UI to SN plane, Interincisal angle, IMPA is 4.458 mm, 118.08 ?,112.16?, 115.64? and95.98? respectively. Whereas in soft tissue parameter, mean value of UL-SNpog’, LL-SNpog’, LLSMe, Sn-ULI, Sline to lower lip, upper lip thickness andLower lip thickness are 2.91mm, 3.34mm, 41.2, 15.36mm, 2.136mm, 13.964 mm and 12.42mm respectively.

Conclusion: There is correlation of hard tissue to soft tissue. Hence clinicians and researchers must give due considerations while working on these parameters.
