Objective: The objective of this paper was to cephalometrically determine the center of the anteroposterior curve of occlusion, and its relation to standardized landmarks, to establish a suitable occlusal curve for the restoration of maxillary and mandibular arches in a selected local population. To the best of the authors' knowledge, this was the first cephalometric study identifying variations occurring in the anteroposterior curve in this population.
Materials and Methods: A total of 80 patients (40 males and 40 females) with Angle's Class I occlusion and normal growth pattern were selected. Landmarks were established following tracings on standardized lateral cephalograms. The center of the occlusal curve was determined, and its distance from the nasion, lachryma, and orbitale was statistically compared using ANOVA, post hoc and proximal matrix tests in males and females. In addition, a relationship between the depth of occlusal curve and the condyle was established.
Results: The mean distances of the center from nasion, lachryma, and orbitale (statistically significant) were 11.15 mm ± 5.65 mm, 18.68 mm ± 8.6 mm and 33.10 mm ± 10.13 mm for females (P < 0.001) and 9.7 mm ± 4.69 mm, 16.80 mm ± 6.45 mm and 31.22 mm ± 8.51 mm (P < 0.001) for males, respectively. Depth of the curve and distance from the condyle had an inverse corelation.
Conclusion: Nasion is closest to the center of the curve of occlusion in both females and males followed by lachryma and orbitale. Hence, nasion can be considered as a point of reference clinically while determining anteroposterior curve of occlusion.
