Abstract :Purpose: The aim of this study was to compare the mandibular hard and soft tissue measurements of unilateral and bilateral cleft lip and palate patients with non-cleft individuals. Materials and Methods: The study sample comprised of lateral cephalograms of 45 subjects. Sample included 15 non-cleft insert ignore into journalissuearticles values(NC);, 15 unilateral cleft lip and palate insert ignore into journalissuearticles values(UCLP); and 15 bilateral cleft lip and palate insert ignore into journalissuearticles values(BCLP); cases whose age were between 15 to 17. 1 angular 13 linear measurements were carried out using Arnett and Gunson soft tissue cephalometric analysis and 4 angular measurements were calculated with Steiner Analysis. Results: Mandibular incisor inclinations relative to the occlusal plane insert ignore into journalissuearticles values(Md1-Md OP); were significantly greater and mandibular incisor projections insert ignore into journalissuearticles values(Md1-TVL); were significantly retrusive in cleft subjects insert ignore into journalissuearticles values(p<0.05);. Projection values pertaining to lower lip anterior insert ignore into journalissuearticles values(LLA-TVL);, soft tissue B point insert ignore into journalissuearticles values(B’-TVL);, and soft tissue pogonion insert ignore into journalissuearticles values(Pog’-TVL); were significantly deficient as well in cleft patients insert ignore into journalissuearticles values(p<0.05);. Sagittal position of the maxilla insert ignore into journalissuearticles values(SNA); insert ignore into journalissuearticles values(p<0.001); and intermaxillary relation of the jaws insert ignore into journalissuearticles values(ANB); were significantly deficient in UCLP subjects insert ignore into journalissuearticles values(p<0.05); and BCLP individuals insert ignore into journalissuearticles values(p<0.01);. LLA-TVL and B’-TVL correlated with SNB in cleft patients insert ignore into journalissuearticles values(p<0.05);. Conclusion: Decreased lower lip and chin projection values suggest that mandibular region of cleft patients should be taken into account in forming the treatment plan to improve the esthetic outcome of orthodontic and plastic surgery interventions.
