Class II malocclusion are complex anomalies of the skeletal and dental systems. The aim of this study is that the rengenkefalometrics analysis closer determine the morphological characteristics of this malocclusion. For this study were used 30 patients aged 18-30, previously clinically diagnosed class II, before the planned orthodontic treatment. The results analisis lateral cephalometric radiographs were compared with the 30 patients with class I malocclusion. Analyzed three linear and two angular cranial base dimensions and nine angular and four linear measures from the facial skeleton. The Results show: No statistically significant differensis in cranial base angle (SNBa) and anterior cranial base length (S–N) between class II and control Class I. Angle maxillar prognathism ( SNA) is no signifikant different between class I and Class II but SNB angle were signifikant smaller. The length of maxillary base (A`-SnP) is longer and the length of mandibule (Pg`-MT1/MT) is signifficantly smaller. The gonial angle (ArGo–Me) was smaller with open articular angle (GoArSN). Morphological characteristics of class II malocclusion are , retrognathic and smaller mandibular ligth, normognathic and longer maxilla, open articular angle with vertical tendency of the craniofacial growth pattern.

Postoje brojni faktori koji mogu da utiču na kraniofacijalnu morfologiju, prvenstveno genetski faktori i faktori spoljne sredine. Cilj ove studije je da se na onovu podataka dobijenih pregledom školske dece dobije približniji opis kraniofacijalne morfologije na ovoj teritoriji. Istraživanjem je bilo obuhvaćeno 330 dece starosti od 8 do 11 godina. Za ovu studiju koristili smo standardne antropometrijske metode za merenje širine i visine lica, širine i dužine lobanje i izračunavanje indeksa lobanje i lica. Dobijeni rezultati su statistički obrađeni a Z skorom izračunat indeks kraniofacijalne varijabilnosti (CVI). On na numerički način opisuje varijabilnost kraniofacijalne morfologije i postojanje slučajeva izvan opsega ovog indeksa. Prema prosečnim vrednostima indeksa lica dečaci i devojčice u gotovo svim ispitivanim godištima pripadaju kategoriji mezoprozopa (47.4%). Analize indeksa lobanje kod dečaka i devojčica govori da su najcesce zastupljeni brahiokefali (52.2%), zatim mezokefali (43.5%) i dolihokefali (4.3%).

Class III malocclusion are complex anomalies of the skeletal and dental systems. The aim of this study is that the sample of 30 untreated orthodontic patients, aged 18-30 years, rendgencephalometrics analysis closer to determine the mor- phological characteristics of this malocclusion. In patients previously clinically diagnosed class III. For this analysis, were used in a number of cephalometrics points on the basis of which the measured angles and planes. The results were compared with the patients with class I malocclusion and they point to the following morphological characteristics of class III maloc- clusion: a smaller cranial base, normognathic and normal size maxilla, prognathic mandible and chin, the greater the total mandibular length, open gonial angle and a larger anterior and lower posterior facial height.
Key words: malocclusion; morphology; cephalometrics

Introduction: Most permanent teeth erupt and establish proper occlusion. In some cases, the permanent teeth have a problem in the eruption and remain impacted in bone.There are two possibilities. 1. Extraction of impacted tooth and its replacement implant or a prosthetic replacement, 2. Surgical release of the impacted teeth and orthodontic traction in the dental arch. The time of treatment, type of surgery release impacted teeth, orthodontic techniques and possible problems during treatment, depending on the type of the impacted tooth and its location. Case report: Clinical examination 14-year-old patients concluded the lack of maxillary canine teeth in the dental arch. Panoramic image showed bilateral canine impaction in the upper jaw. The analysis of X-ray image was recorded axial and in the middle alveolar position of both the impacted tooth. This is why we chose the of closed eruption method. Discussion: Impacted maxillary canines, the middle alveolar ridge treated by closed eruption, except for a slight increase in clinical crown of the tooth does not show other changes deteriorate.

The objectiv of this study were to evaluate the applicability of the methods of Tanaka and Johnston predictions to our population.60 dental study casts(30 male and 30 female patients)were used.The measured sum of the width of the permanent canine and premolars were compare with values obtained from Tanaka-Johnston formula.The method of Tanaka-Johnston were tended to exaggerate the actual sum of the lower permanent canine and premolars for male and female samples,with statistically significant differences.

Introduction: In 1899. Angle introduced his own classification of malocclusions which was established anteroposterior relationship between maxilla and mandible.Later cephalometric examinations showed possible variations of the relationship between maxilla and mandible to cranial base, in all three classes. The aim work: The aim of this work was to ascertain types of the relationship between maxilla and mandible to cranial base in persons with I,II and III class by Angle. Material and method:The profile telerendgenograms were used in male and female aged aprroximately 14,5 years. On the bases of clinical examination and analysis of models,the patients were previously distributed into three groups with 50 examinees in each,according to Angle classification of malocclusions in saggital plain.SNAand SNB angle were analysed, and on the bases were individual values, the type of the relation between maxilla and mandible to cranial base was determined for every examinee. Results: In persons with Angle I class, eight types of the relationship were determined,while five types in persons with Angle II and III class of the relationship of jaw to cranial base. Conclusion: Because of large number of variationsof the relationship of jaw to cranial base diagnostic procedure should evolve, and treatment of the very similar cases should be different
