The purpose of this study was to compare facial soft tissue thickness ofIraqi patients with different types of skeletal relations.Materials and method: Lateral cephalometric study was conducted on 60 adult Iraqi patients with normal verticaldimensions (diagnosed clinically and radiographically as SN-Mandibular Plane angle 28›-36›), aged 18-30 years,classified according to skeletal sagittal relationship using ANB angle into three groups (each group consist of 10 maleand 10 female subjects): Class I group (ANB2-4›), Class II group (ANB>4›) and Class III group (ANB<2›). Cephalometricanalysis of soft tissue thickness was achieved by 10linearmeasurements using AutoCAD program 2007.Results and Conclusions: This study showed that the facial soft tissue thickness measurements were significantly higherin male than in female in almost all measured midline landmarks, in comparing the three skeletal relation groups,Class III group show the highest readings when compared to Class I and Class II, Class II show the lowest resultsamong the three groups (except for the labiomental fold area and pogonion area), while Class I group lies betweenthe other two groups for all the measured values.
