The study examines the relationships between different craniometric distances and the nasion-gnathion (N-Gn) distance which represents the lower two thirds of the face in vertical dimension determination. The highest degree of correlation (r = 0.9217; p < 0.05) was observed between the N-Gn and zygion-zygion (Zy-Zy) distances. The N-Gn distance could be determined using the formula N-Gn = Zy-Zy / 1.15 or by means of regression analysis: N-Gn = 0.54749 + 0.82822 x Zy-Zy. Considering that the coefficient of correlation between N-Gn and Zy-Zy was higher than the one between the eye-ear (E-E) and the subnasale-gnathion (Sn-Gn) distances reported earlier (r = 0.8676) it was concluded that calculating the N-Gn distance from the Zy-Zy distance was more reliable. The fact that none of the calculated correlation coefficients was 1, but was lower than 1, points to the presence of individual variations of the cephalometric parameters. Although the method cannot be taken as absolutely reliable, owing to its simplicity and practical applicability it can be recommended for use in everyday clinical practice in combination with other methods for the determination of the vertical dimension of occlusion.

Ova studija proučava odnose između različitih kraniometrijskih udaljenosti i udaljenosti nathion-gnathion (N-Gn) koja predstavlja visinu donje dvije trećine lica pri određivanju vertikalne dimenzije okluzije. Dobiven je najveći stupanj korelacije (r = 0.9217, p < 0.05) između N-Gn i udaljenosti zygion-zygion (Zy-Zy). Izračunavanje se može formulom: N-Gn = Zy-Zy / 1.15 ili formulom pravca regresije: N-Gn 0.54749 + 0.82822 xZy-Zy. Zbog većeg koeficijenta korelacije između N-Gn i Zy-Zy nego između udaljenosti oko-uho (E-E) i subnasale-gnathion (Sn-Gn), dobivenog u prvom dijelu ove studije r = 0.8676) može se zaključiti da je izračunavanje udaljenosti N-Gn iz udaljenosti Zy-Zy pouzdanije. Niti jedna od ispitivanih korelacija nije potpuna (r < 1), što upućuje na individualne varijacije mjerenih kefalometrijskih parametara. Iako se ova metoda ne može smatrati apsolutno pouzdanom, zbog svoje jednostavnosti i praktične primjenjivosti može se preporučiti za svakodnevnu stomatološku praksu u kombinaciji s drugim metodama određivanja vertikalne dimenzije okluzije.
