Determination of craniofacial relation among the subethnic Indian population: A modified approach (vertical evaluation).

ABSTRACT

Aim: To measure the vertical linear cephalometric dimensions of the anterior and posterior segments of the craniofacial complex and establish ratios between vertical linear dimensions in subjects with normal occlusion, pleasing profile, and facial harmony. Setting and Sample Population Department of Orthodontics, Saveetha University. Lateral cephalograms of 120 subjects of both sexes in the age group of 17-28 years with normal occlusion belonging to Chennai, India. Materials and Methods: The vertical segments measured are anterior maxilla, posterior maxilla, and ramus-cranial floor vertical. The facial heights were measured in the anterior and posterior region of the craniofacial complex. Establish ratios and proportions between the vertical segments and different facial heights. Results: In both the sexes, the ratio between anterior maxilla, posterior maxilla, and ramus-cranial floor vertical is 111, PTFHATFH is 11, AUFHATFH is 25, ALFHATFH is 35, PUFHPTFH is 12, PLFHPTFH is 12, AUDHALDH is 23, and facial depth is 21. PUDHPLDH is 79 in females and 34 in males. There was a statistically significant difference in posterior total facial heightanterior total facial height ratio between the two sexes with a "P" value of 95%. Conclusion: Thus, the anterior maxilla, posterior maxilla, and cranial floor-ramus vertical composite are in dimensional balance in subjects with normal occlusion and facial harmony. This analysis helps to identify skeletal deviations in size and position in the vertical dimension and allows the clinician to outline an appropriate treatment.
