To measure the inter-radicular spaces in both arches for miniscrew implant placement and to determine the most reliable sites using CBCT. A CBCT radiograph was taken for 75 subjects that met with inclusion criteria. They were divided into 3 categories- Hypodivergent, average, and hyperdivergent group. Images were calibrated by using software and printed as a film. Interradicular space on the right side of the jaw was measured in the sagittal plane after assuming the jaw to be symmetrical. Bucco-lingual and mesiodistal width were measured up to desired bone levels. In vertical growth pattern, in posterior maxilla highest mesiodistal width between 2nd premolar and 1st molar at 7mm. In the mandible, it was between the 1st and 2nd molar at 11mm. In horizontal growth pattern, in posterior maxilla highest mesiodistal width between 1st and 2nd premolar, and mandible it was between 1st and 2nd molar at 11mm. In average growth pattern, in posterior maxilla highest mesiodistal width between 2nd premolar and 1st molar and 1st molar at 7mm. In the mandible, it was between the 1st and 2nd molar at 11mm. The importance of the relationship between the growth pattern and the availability of inter radicular space may aid the clinician in planning appropriate surgical sites for miniscrew implant placement.

Aim: To determine the correlation between palatal rugae (PR) pattern and subjects with vertical, average, and horizontal growth pattern and to determine gender variation if any. Material and Methods: One hundred and twenty study models were divided into horizontal, vertical, and average growth patterns with 40 (20 males and 20 females) samples in each group. The pattern of PR was assessed in each group using a template. Result: Type B (wavy type) PR occurs more often in horizontal and average growth pattern (80% and 72.5% respectively), whereas its occurrence in vertical growth pattern subject is the least among other growth patterns, that is, 42.5% of the total subjects. Type E (curved type) PR has appeared highest in 27.5% of average growth pattern patient followed by 12.5% of vertical growth pattern subjects. The occurrence of type E PR is least in horizontal growth pattern which is just 5% of the total subjects. Conclusion: Curved-type PR was more prevalent in vertical and average growth patterns. Diverging PR pattern was mainly seen in vertical growth pattern. PR also shows sexual dimorphism. The association is clinically significant as it will lead to determination of facial vertical growth pattern at early age; thus, it serves as a diagnostic adjunct for different malocclusions very early in life and aids in preventive or interceptive orthodontic measures to alleviate forthcoming growth pattern.

Introduction. The Herbst device is widely used for correction of class II malocclusions; however, most of the researches carried out on the Herbst appliance in literature do not take into account patients with a different mandibular divergence. The aim of this study was to investigate the effects of Herbst on dental and skeletal structures and to evaluate possible influence of vertical facial growth patterns. Methods. A retrospective study was conducted on lateral cephalograms of 75 growing patients (mean age: 9.9 ± 1.9 years) with class II malocclusion treated with Herbst. Subjects were divided into 3 groups using the mandibular divergence index (SN and GoMe angle). Cephalometric parameters were evaluated using the modified SO (sagittal occlusion) Pancherz’s analysis. A statistical analysis was conducted to evaluate differences among groups using ANOVA. Results. Our study showed differences in response to treatment depending on patient’s facial vertical growth pattern. Cranial base angle and mandibular rotation were significantly different (p<0.05) between hypodivergent patients and normodivergent patients and between hypodivergent and hyperdivergent subjects. Conclusion. Hypodivergent patients increased their mandibular divergence during treatment to a greater extent than normodivergents; moreover, hyperdivergent patients exhibited a decreased mandibular divergence at the end of the treatment.

Mandibular growth pattern (MGP) prediction plays an important role in orthodontic treatment planning. This study sought to assess the mandibular symphyseal width in adolescents with different mandibular growth patterns (MGPs) so as to see whether a correlation exists. This study was conducted on 90 lateral cephalograms of patients aged between 10 and 16 years. The subjects were divided into normo-divergent, hypodivergent and hyperdivergent subgroups based on the gonial angle. The symphyseal measurement included width or depth of the mandibular symphysis according to Akietal study. He suggested that a mandible with anterior growth direction was associated with a large depth of the symphysis. In contrast, a mandible with a posterior growth direction was associated with a small depth of symphysis. To assess the correlation between mandibular symphyseal width and mandibular growth pattern, Pearson’s correlation test was done. Correlation is significant at the 0.01 level (2 tailed). A P-value which is less than 0.05 was considered statistically significant. The mandibular symphyseal width was found to be strongly associated with the MGP. It can be inferred from the results that in vertical growth pattern, as the gonial angle increases, symphyseal width decreases and in horizontal growth pattern, as the gonial angle decreases, symphyseal width increases. Also, in vertical growth pattern subjects, the mandibular symphyseal width is narrower. In contrast, in horizontal growth pattern subjects, the mandibular symphyseal width is wider.

OBJECTIVE: To evaluate possible differences in mandibular behavior in Class I individuals with vertical and horizontal growth patterns. METHODS: The sample consisted of 20 untreated Class I individuals divided into: Group 1 comprising 10 individuals with vertical growth pattern and Group 2 comprising 10 individuals with horizontal growth pattern, all of them belonging to the Burlington Growth Center files, University of Toronto-Canada, radiographically followed-up at ages 9, 12 and 21. Cephalometric radiographs, determined mean values for a long-term evaluation of mandibular behavior using the following measurements: SNB, Co-GN, SN.GoMe, anterior facial height and posterior facial height. RESULTS: SNB and Co-Gn values were higher in horizontal growth group at all of the ages studied; SN.GoMe measure was significantly lower in horizontal growth group; anterior facial height (AFH) showed lower values in individuals with horizontal growth pattern; and posterior facial height (PFH) showed lower values in individuals with vertical growth pattern. CONCLUSION: Long-term comparisons of Class I individuals' growth tendencies indicate that there are significant differences between both groups. Mandible showed a trend to clockwise rotation in Group 1. Group 2 showed a trend to brachycephalic facial form, due to the deficit in vertical development with regard to anterior facial height.

ABSTRACT Purpose The purpose of this study was to analyze and comparethe association between cervical spine and face in subjects with vertical and horizontal growth pattern using lateral cephalogram. Materials and methods Lateral cephalograms of 75 subjects between ages of 18 and 35 years were taken and analyzed. The study sample was divided into three groups of 25 individuals each; i.e., vertical growth pattern (gonial angle > 125°); horizontal growth pattern (gonial angle < 121°); and control group with average growth pattern (gonial angle 123° ± 2.5°). The relation between upper cervical vertebrae and face was compared between three groups by taking linear measurements. Results A statistically significant difference was observed in vertical dimensions of second cervical vertebra when it was correlated with anterior cranial base, maxilla and mandible in adults having horizontal and vertical growth pattern as compared to individuals with average growth pattern. Linear vertical measurements between maxilla to cervical spine and mandible to cervical spine were less in horizontal growth pattern as compared to vertical and average growth pattern. The p-value of SCV2—0.001, GoCV2—0.405, and PmCV2—0.001 showed significant results within intergroups. Conclusion It can be concluded that there exists an association between the morphology of the cervical vertebrae and the vertical and horizontal skeletal growth patterns.

In orthodontics and dentofacial orthopaedics, a thorough knowledge of growth and development is essential in order to understand various factors that contribute as to how a particular type of growth takes place. When planning of orthodontic treatment for a malocclusion, one has to take into account the growth pattern, because it would considerably affect the success of the treatment. The purpose of this study was to compare antegonial notch depth, symphysis morphology, and ramus morphology in different growth patterns in skeletal class I and class II subjects. In this study, a total of 60 cephalograms were taken which comprised 30 cephalograms in skeletal class I and 30 cephalograms of skeletal class II patients. The groups were further divided into three groups, namely average, horizontal, and vertical growth patterns based on Jarabak’s ratio. Antegonial notch depth, symphysis width and symphysis angle, and ramus height were measured and compared between the growth patterns and between class I and class II skeletal patterns. An analysis of variance (ANOVA) test was performed to determine the comparison between groups for all these variables in both skeletal class I and class II. Independent 't' test was done to determine the comparison between skeletal class I and class II subjects for all variables. Mean and SD values for all variables were determined for all the groups. Depth of antegonial notch was found to be greater in vertical growth patterns compared to horizontal and average growth patterns. Large symphysis angle and symphysis width were noted in a horizontal growth pattern. Increased ramus height was noted in horizontal and average growth patterns. There was no significant difference between skeletal class I and class II malocclusion for all parameters.

ABSTRACT Introduction The aim of this study was to establish a new cephalometric parameter, named the Dhaval—Rohan angle (DR), to assess the vertical skeletal patterns on a lateral cephalogram with accuracy and reproducibility. Materials and methods One hundred and twenty pretreatment lateral cephalograms of the patients visiting the department of orthodontics and dentofacial orthopedics for treatment were obtained and divided into three groups. i.e., horizontal growth pattern, average growth pattern, and vertical growth pattern cases based on the routinely used cephalometric parameters; FMA, SN-GoGn, Y-axis angle and Jarabak ratio. This angle uses three skeletal landmarks, the point C (center of the condyle), point M (midpoint of premaxilla), and point G (center of the largest circle that is tangent to the internal inferior, anterior, and posterior surfaces of the mandibular symphysis). Results The one-way analysis of variance (ANOVA) test showed that the three groups studied were not the same for DR angle and the post hoc Tukey test found the groups to be significantly different. According to the Student's t-test, there was no statistically significant difference in mean values of DR angle between males and females. Conclusion Cephalometric evaluation of young adults shows that the DR angle below 28.5° indicates a horizontal growth pattern, between 28.5 and 32.5° indicate an average growth pattern and above 32.5° indicate a vertical growth pattern.

Movement Differences

The objectives of this study were to determine the amplitude of movement differences and asymmetries between feet during the stance phase and to evaluate the effects of foot orthoses (FOs) on foot kinematics in the stance phase during running. In total, 40 males were recruited (age: 43.0 ± 13.8 years, weight: 72.0 ± 5.5 kg, height: 175.5 ± 7.0 cm). Participants ran on a running treadmill at 2.5 m/s using their own footwear, with and without the FOs. Two inertial sensors fixed on the instep of each of the participant’s footwear were used. Amplitude of movement along each axis, contact time and number of steps were considered in the analysis. The results indicate that the movement in the sagittal plane is symmetric, but that it is not in the frontal and transverse planes. The right foot displayed more degrees of movement amplitude than the left foot although these differences are only significant in the abduction case. When FOs are used, a decrease in amplitude of movement in the three axes is observed, except for the dorsi-plantar flexion in the left foot and both feet combined. The contact time and the total step time show a significant increase when FOs are used, but the number of steps is not altered, suggesting that FOs do not interfere in running technique. The reduction in the amplitude of movement would indicate that FOs could be used as a preventive tool. The FOs do not influence the asymmetry of the amplitude of movement observed between feet, and this risk factor is maintained. IMU devices are useful tools to detect risk factors related to running injuries. With its use, even more personalized FOs could be manufactured.
