Evaluation between Soft Tissue Chin Thickness and Mandibular Divergence Pattern.
Journal Title: International Journal of Dental Science and Innovative Research (IJDSIR) - Year 2019, Vol 2, Issue 2
Abstract
Objectives: To evaluate the association between the soft tissues chin [STC] thickness and mandibular divergence pattern. Methods: 200 pre-treatment lateral cephalograms of adult subjects were taken. Patients were stratified into four groups based on the divergence pattern defined by the mandibular plane to cranial base angle (MP/SN; average = 320 + 50). The angle included Palatal Plane to Mandibular Plane (PP/MP), Palatal Plane to Horizontal (PP/H), Mandibular Plane to Horizontal (MP/H), and Mandibular Plane to Anterior cranial base (MP/SN). The sagittal relationship between the jaws was assessed by the ANB angle. The STC thickness was measured at three different levels- (1) Pog-Pog’; (2) Gn-Gn’; and (3) Me-Me’. The three distances were measured using NEMOTEC Software. Results: All Skeletal cephalometrics had the highest measurements in the hypodivergent group H and gradually decreased across the groups, the lowest being in the hyperdivergent group L. All skeletal cephalometric measurements (PP/MP, PP/H, MP/H, MP/SN) were statistically significant across four groups stratified based on MP/SN angle using Anova F Test (p < 0.05). The ANB angle was not statistically significant among the four groups. (P value = 0.106). Conclusion: Soft tissue thickness measurements were smaller in adult patients with vertical hyperdivergent pattern compared with clinically normal and hypodivergent patterns. Subjects with hyperdivergent mandible exhibited a statistically significantly thinner STC at Gn’ and Me’ in comparison with subjects having a hypodivergent pattern. All STC measurements were greater in men than in women.
