Morphological analysis of the step-by-step elliptical Fourier reconstructions. Example of a lateral mandibular outline reconstruction in hemizygous Eda^Ta/Y mice using the 24 first Fourier harmonics. The ramus and the body of the mandible (r.m. and b.m. respectively) started to be described with the second and third harmonics. The coronoid process (c.p.), the mandibular condyle (m.c.), and the angular process (a.p.) appeared with the fifth harmonic. The mandibular notch and the concavity of the posterior border of the ramus were reconstructed together with the previous anatomical structures. Coronoid process, mandibular condyle, and angular process were correctly outlined with the summation of the 9th harmonic, and subtle features of these three parts of the mandible were characterized from the 16th harmonic. The height of the body of the mandible was defined around fourth and fifth harmonics. The incisor alveolar bone (i.a.) appeared with the fourth harmonic and a correct description was acquired using the first ninth harmonics.
