Assessment of first molars sagittal and rotational position in Class II, division 1 malocclusion

OBJECTIVE: This study assessed the anterior-posterior positioning of the upper and lower first molars, and the degree of rotation of the upper first molars in individuals with Class II, division 1, malocclusion. METHODS: Asymmetry I, an accurate device, was used to assess sixty sets of dental casts from 27 females and 33 males, aged between 12 and 21 years old, with bilateral Class II, division 1. The sagittal position of the molars was determined by positioning the casts onto the device, considering the midpalatal suture as a symmetry reference, and then measuring the distance between the mesial marginal ridge of the most distal molar and the mesial marginal ridge of its counterpart. With regard to the degree of rotation of the upper molar, the distance between landmarks on the mesial marginal ridge was measured. Chi-square test with a 5% significance level was used to verify the variation in molars position. Student's t test at 5% significance was used for statistical analysis. RESULTS: A great number of lower molars mesially positioned was registered, and the comparison between the right and left sides also demonstrated a higher number of mesially positioned molars on the right side of both arches. The average rotation of the molars was found to be 0.76 mm and 0.93 mm for the right and left sides, respectively. CONCLUSION: No statistically significant difference was detected between the mean values of molars mesialization regardless of the side and arch. Molars rotation, measured in millimeters, represented ¼ of Class II.

Cephalometric evaluation of the predictability of bimaxillary surgical-orthodontic treatment outcomes in long face pattern patients: a retrospective study

OBJECTIVE: The aim of this study was to compare by means of McNamara as well as Legan and Burstone's cephalometric analyses, both manual and digitized (by Dentofacial Planner Plus and Dolphin Image software) prediction tracings to post-surgical results. METHODS: Pre and post-surgical teleradiographs (6 months) of 25 long face patients subjected to combined orthognathic surgery were selected. Manual and computerized prediction tracings of each patient were performed and cephalometrically compared to post-surgical outcomes. This protocol was repeated in order to evaluate the method error and statistical evaluation was conducted by means of analysis of variance and Tukey's test. RESULTS: A higher frequency of cephalometric variables, which were not statistically different from the actual post-surgical results for the manual method, was observed. It was followed by DFPlus and Dolphin software; in which similar cephalometric values for most variables were observed. CONCLUSION: It was concluded that the manual method seemed more reliable, although the predictability of the evaluated methods (computerized and manual) proved to be reasonably satisfactory and similar.

Estimativa do surto de crescimento puberal pela avaliação das vértebras cervicais em radiografias cefalométricas laterais

The aim of this research was to estimate the skeletal growth and development by observingradiographically the morphological changes of the first, second and third cervical vertebrae, according to the method proposed by Hassel &Farman32 (1995) in patients who were going through the outbreak of pubertal growth. The radiographic inspection of the cervical vertebrae was performed by means of cephalometric radiographs and the outbreak of pubertal growth was identified through the events of ossification of the hand and wrist. For that purpose, we selected thecephalometric radiographs and hand•wrist radiographs of 110 Brazilianleukoderms, male and female,with chronological age ranging from 8 to 14,6 years old for the girls and from 9,5 to 15,4 years old for the boys.The results showed that there was a statistically significant correlation between the maturation indicators of the cervical vertebrae and the patients who were going through the outbreak of pubertal growth. The conclusion was that the radiographic evalution of the changes of the cervical vertebrae, in the cephalometric radiographs, is an alternative parameter, which is reliable and practical in the skeletal evalution, and the it completes the range of information that must be obtained from the patient under orthodontic treatment and that it can, circumstantially, replace other methods of evalution
