| Abstract | Cilj istraživanja: Svrha istraživanja bila je utvrditi razliku između parametara kranijalne baze, maksile, mandibule i dentoalveolarnih parametara između klase I, klase II potklase 1, klase II potklase 2 i klase III.
Materijali i metode: U ispitivanju su korištene 43 laterolateralna rendgenograma glave ispitanika snimljena prije ortodontske terapije. Kefalometrijska obrada provedena je u računalnom programu AudaxCeph (Audax, Ljubljana, Slovenija) korištenjem Zagreb 82 i Ricketts analize. Za svakog ispitanika su mjerene 24 linearne i kutne varijable.
Rezultati: Nema statistički značajne razlike među mjerenim parametrima kranijalne baze unutar pojedinih skeletnih klasa. Duljina korpusa maksile (SNA-SNP) ne pokazuje statistički značajnu razliku između ispitivanih skeletnih klasa (51,22±3,27 mm vs 52,29±3,70 mm vs 53,04±2,00 mm; P=0,068), dok duljina korpusa mandibule (Me-Go) pokazuje statistički značajnu razliku između skeletne klase II i skeletne klase III (64,19±4,90 mm vs 70,81±5,08 mm; P=0,039). Vrijednost interincizalnog kuta u ispitanika sa skeletnom klasom II/1 su manje, a u ispitanika sa skeletnom klasom II/2 i skeletnom klasom III veće u usporedbi s ispitanicima sa skeletnom klasom I (119,01±7,07° vs 145,77±7,37° vs 138,54±5,73 ° vs 129,02±11,82°; P<0,001).
Zaključak: Rezultati nisu pokazali razliku među mjerenim parametrima kranijalne baze između pojedinih ispitivanih skeletnih klasa, dok je vidljiva razlika u različitim dentoalveolarnim, skeletnim i čeljusnim parametrima. Dentoalveolarna kompenzacija je prirodan proces pokušaja maskiranja anteroposteriornih skeletalnih diskrepanca. |
| Abstract (english) | Objectives: The aim of the study was to determine the difference between cranial bases, maxilla, mandible, and dentoalveolar parameters between class I, class II/1, class II/2, and class III.
Materials and Methods: In this study there were forty-three laterolateral head roentgenogram of participants captured before starting orthodontic therapy used. Cephalometric processing was performed in the AudaxCeph (Audax, Ljubljana, Slovenija) using Zagreb 82 and Ricketts analysis. Twenty-four linear and angular variables were measured for each subject.
Results: There were no statistically significant difference between the measured cranial base parameters within the individual skeletal classes. The length of maxilla corpus (SNA-SNP) showed no statistically significant difference between the skeletal classes (51.22±3.27 mm vs 52.29±3.51 mm vs 56.11±3.70 mm vs 53.04±2.00 mm; P=0,068), while the length of mandible corpus (Me-Go) showed a statistically significant difference between skeletal class II and skeletal class III (64.19±4.90 mm vs 70.81±5.08 mm; P=0.039). The value of the interincisal angle was lower in participants with skeletal class II/1 and higher in participants with skeletal class II/2 and skeletal class III compared to participants with skeletal class I (119.01±7.07° vs 145.77±7.37° vs 138.54±5.73° vs 129.02±11.82°; P<0.001).
Conclusion: The results showed no difference between the measured cranial base parameters between the individual skeletal classes, while there were noticeable differences in different dentoalveolar, skeletal, and jaw parameters. Dentoalveolar compensation is a natural system for camouflaging skeletal discrepancies in three planes of space. |
