“…7,8 Although the distance between S-N is used to measure the anterior cranial base, some authors claim that using point Ba or Ar is more accurate. 9 On the other hand, Bjork says that point Ar should be included in the analysis due to its easier identification on radiographs. 10 Varjanna et al used point Ba in their research because they considered that there is a larger distance between Ar and the cranial base.…”

Background: Previous studies regarding various types of malocclusions have found correlations between the angle of the base of the skull and prognathism. Aim of the study: This cephalometric study sought to investigate the function of the cranium base angle in different types of malocclusion on a group of Romanian subjects. Materials and methods: Forty-four cephalometric radiographs were selected from patients referred to orthodontic treatment. The cephalometric records were digitized, and with the CorelDRAW Graphics Suite X5 software 22 landmarks have been marked on each radiograph. A number of linear and angular variables were calculated. Results: The angle of the base of the skull was found to be higher in Class II Division 1 subjects compared to the Class I group. The cranial base lengths, N-S and S-Ba, were significantly larger in both categories of Class II malocclusion than in Class I patients, but measurements were comparable in Class I and Class III. The SNA angle showed no considerable variation between Class I subjects and the other groups. SNA-SNP was significantly

“…Hence, it could be hypothesized that fusion anomalies show a dimorphic pattern in their occurrence. 1 However, Sonnesen and Kjaer, 8 Faruqui et al, 1 and Arntsen and Sonnesen 28 attested that there was no significant gender difference in the occurrence of CVAs. Similarly, the current study did not reveal gender tendency for occurrence of CVA.…”

Objective: The literature indicates a correlation between vertebral morphologic anomalies and some orthodontic malocclusions. The aim of this study was to examine the occurrence of the types of cervical vertebral anomalies (CVAs) in subjects with transverse maxillary deficiency (TMD) and to compare this with the occurrence of CVA in a control group without TMD. Materials and Method: A sample of 47 Turkish patients (17 boys, 30 girls) with TMD and another sample of 47 Turkish patients (15 boys, 32 girls) with adequate maxillary transversal dimensions was studied. A visual assessment of the cervical column was made using lateral cephalometric films. Characteristics of the cervical column were classified according to Sandham as fusions and posterior arch deficiencies of C1 (PADs). Clinically normal appearance was determined when the first 4 vertebrae could be traced as separate entities with all anatomic components present. Differences in occurrence of CVA between the groups and between genders were assessed by v 2 independence test. Results: In the TMD group, 10,6% of the subjects had fusion in the cervical column, and 14,9% had PAD. In the control group, 17% of the subjects had fusion of the cervical column, and 8,5% had PAD. The occurrence of PAD was significantly increased in the TMD group (p,0.05), while no significant difference was found between the groups for occurrence of fusion (p.0.05). No statistically significant gender differences were found in the occurrence of CVA in the TMD group and the control group (p.0.05). Conclusion: No difference was found in the occurrence of fusion between the subjects with TMD and the subjects without TMD, and the occurrence of PAD was significantly increased in subjects with TMD.

Jedan od faktora koji utiču na rast skeleta lica, može biti i položaj glave u odnosu na vratnu kičmu. Cilj ove studije je da se ispita uticaj položaja glave na visinu lica i inklinaciju vilica. Takođe na osnovu procentualnog odnosa prednje i zadnje visine lica, određen je tip rasta lica. Tip rasta lica je doveden u vezu sa položajem glave, koji je procenjen na osnovu vrednosti kraniocervikalnog ugla. Analizirani su profilni telerendgen snimci ukupno 90 ortodontskih pacijenata, koji su bili podeljeni u tri grupe na osnovu vrednosti ANB ugla kao pokazatelja sagitalnog skeletnog odnosa vilica. Dobijeni rezultati ukazuju da je položaj ekstenzije glave u odnosu na vratnu kičmu najčešče udružen sa malokluzijama II klase. Takav položaj glave povezan je sa povećanom prednjom i smanjenom zadnjom visinom lica i stvara uslove za rast lica rotacijom unazad. Povećane vrednosti kraniocervikalnog ugla pračene su povećanim vrednostima uglova inklinacije vilica, što takođe utiče na povećanje predne visine lica.Ključne reči: položaj glave, visina lica, inklinacija vilica, rast lica. UVODPod pravilinim držanjem tela podrazumeva se navika neusiljenog uspravnog stava ili stava čoveka pri hodanju. Pravilno držanje tela podrazumeva i odgovarajući položaj glave, pri čemu je čelo paralelno sa frontalnom ravni, a pravac pogleda paralelan sa horizontalnom ravni.Položaj glave u odnosu na vratnu kičmu, dovedi se u vezu sa morfologijom lica i vilica, sa položajem i među-sobnim odnosom maksile i mandibule, njihovom dužinom i inklinacijim, facijalnim prognatizmom i retrognatizmom i brojnim drugim pokazateljima koji su od interesa za ortodonte. Pretpostavlja se da jedan od faktora koji utiču na rast skeleta lica, može biti i položaj glave. Name, kada je glava ekstendirana u odnosu na vratnu kičmu, to dovodi do istezanja kože lica i mišićnih pripoja na skeletu lica. Ovo istezanje izaziva porast sile koja deluje na skeletne strukture i može da ograniči rast maksile i mandibule unapred i usmeri ga više unazad.U ortodontskoj literaturi postoje studije koje su ispitivale uticaj položaja glave na kraniofacijalnu morfologiju i rast skeleta lica [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Položaj glave se procenjuje na osnovu kraniocervikalnog ugla koji formiraju osnovna ravan prednje kranijalne baze (NS), i tangenta odontoidnog procesusa (OPT) koja prolazi kroz krajnju zadnju donju tačku na telu drugog vratnog pršljena [2] Smer rasta lica zavisi od rasta pojedinih struktura lica i od njihovih uzajamnih odnosa.Zavisno od dominacije rasta u pojedinim delovima viscerokranijuma, kosti lica u odnosu na bazu lobanje mogu se rotirati anteriorno ili posteriorno iz čega proizilaze horizontalni ili vertikalni rast lica. Ako se proces rasta odvija istim intenzitetom u predelu prednje i zadnje visine lica doći će do rasta lica bez rotacije.Ukoliko dominira rast u predelu zadnje visine lica, rast se odvija rotacijom unapred, a ako je rast izraženiji u predelu prednje visine lica, rast se odvija rotacijom unazad.Iako se zna da gornja i ...
