“…Occ/SN is smaller in the present study suggestive of long face in Moroccan population as they have maxilla rotating downward. 2,3,18 Occ/FH is larger in Moroccan population that can be due to Frankfurt plane inclination. GoGn/SN angle is smaller in Solan population when compared with Moroccan population showing vertical growth pattern and open bite in the Moroccans.…”

“…GoGn/SN angle is smaller in Solan population when compared with Moroccan population showing vertical growth pattern and open bite in the Moroccans. 3 However, the angle of Y-axis was increased in the Solan population when compared with the Moroccan population and it was found to be clinically significant (p < 0.05), stating more vertical growth pattern in Solan population; this is in concordance by Kharbanda et al 17 ANS-Me was found to be smaller in the Solan population when compared with the Moroccan population, reflecting that decreased lower facial heights can be attributed to the decrease in the size of mandible (Yemeni, Iraqi, Moroccan).…”

“…Current knowledge on the morphological and functional aspects of maxillofacial complex, knowledge on genetic complexity of certain morphological structures, knowledge on inseparable association between morphology and function, and knowledge on individual course of neuromuscular processes within the system have necessitated a need to reconstruct the previous natural VDO as precisely as possible. [2][3][4][5][6][7] Various methods of determining VDO other than cephalometry are unfortunately not very reliable; thus, cephalometric techniques have the advantage of providing an initial numerical VDO assessment that can be clinically verified. 8 They determine the correlation between certain craniofacial components (points, lines, and/or angles), which remain relatively unchanged after tooth loss.…”

Introduction The aim of modern cephalometrics is to evaluate the relationship of skeletal and dental functional units of the face and to implement treatment to establish the position of the units horizontally and vertically. Establishing a correct occlusal vertical dimension is considered one of the most important aspects of facial esthetics for patients in need of orthodontic treatment. Aim The aim of this study is to evaluate the vertical dimension of occlusion in varying dental malocclusions in Solan population. Materials and Methods The sample consisted of pretreatment lateral cephalograms of 100 patients (50 Class I and 50 Class II div 1), aged 15 to 30 years; six angular and one linear parameters were measured to determine the vertical dimension of occlusion. Results All the parameters (Frankfort-mandibular plane angle [FMA], Occl/Frankfort horizontal plane [FHA], angle of Y-axis, Occl/SN, GoGn/SN, and ANS-Me) were found to be decreased in Class I than in Class II div 1 malocclusion except (ANS-Xi-Pm). All the parameters were found to be statistically significant (p < 0.05) when compared between groups. When cephalometric norms of the present study were compared with Moroccan population, all parameters (ANS-Xi-Ptm, FMA, Occl/FH, Occl/SN, GoGn/SN, and ANS-Me) were found to be decreased in Solan population except angle of Y-axis. All the parameters were clinically significant (p < 0.05) except ANS-Xi-Pm and FMA that were found to be clinically nonsignificant (p > 0.05). Conclusion Solan population has distinct cephalometric characteristics, which should be used as the reference in future orthodontic treatments.

The following is a retrospective descriptive cross-sectional stud aimed at determining the vertical cephalometric standards of a Moroccan population. The values found will be used to orient the choice of the VDO during complex prosthetic rehabilitations where all dental references are absent. The study was conducted on 80 teleradiographies of subjects consulting the ODF department of the CCTD Casablanca with a skeletal class 1 dental occlusion in the absence of any previous or current orthodontic treatment. After performing the cephalometric tracings, we correlated the VDO with 7 angular measurements: ENA-Xi-Pm, GoGn/SN, Occ/SN, Occ/Fr, SGn/Fr, FMA, GoGn/GoENA. Our study led us to the following results: • For the ENA-Xi-Pm angle, we found a mean value of 47.9. • The GoGn/SN angle averaged 38.3°, it varied in 37.29.° • For the Occ/SN angle, it was found that the average value was 21.2° for the whole sample. • The Occ/Fr angle was on average 9.9.° • The SGn/Fr angle averaged 60° in the Moroccan population. • The measurement of the FMA angle showed an average of 27. • Finally, for the GoGn/GoENA angle, we found a mean value of 50. The comparison of our results with those of studies conducted on different populations showed significant differences. This can be explained by the tendency to hyperdivergence in the Moroccan population, hence the interest in using the mean values specific to each population. The comparison of the global means with the means of each group showed that the angular values in hyperdivergent cases are significantly higher than the global values and the angular values in hypodivergent cases are significantly lower than the global values, and for the normodivergent cases, we found a significant difference only for the values of the FMA angle which is lower than the global value of the sample. And thus, the determination of the VDO using cephalometric analysis represents one of the best methods to correctly restore the occlusal environment in a complex prosthetic project, given that the restauration is based on cephalometric standards of the corresponding population.

“…The use of bone points by cephalometric analysis leads to increased accuracy in measurements because there is no facial or positional manipulation determining freeway space, but a functional method must also be used to improve measurements provided by lateral RX in edentulous patients. Ousehal and Sierpinska 34,35 report that cephalometric studies could lead to an adequate initial VDO, referring to Knebelman's craniometer as an adequate way to determine initial VDO that could be complemented with cephalometric studies. One of the most frequently analyzed concerns is considered by Behrensdorf 36 , who says that age and time using dentures affect VDO reestablishment and mandibular movements.…”

The masticatory system changes as time passes. The vertical dimension of occlusion (VDO) undergoes alterations due to temporomandibular joint disorders which in turn may be caused by related muscle modifications or pathological tooth wear. There are many methods to measure VDO. Among these, the anthropometric method and Knebelman’s craniometric method have been shown to be the most closely related to facial biotype. The aim of this study was to compare data recorded with those two methods. A descriptive cross-sectional study was performed with a total 200 patients. A vernier caliper was used to measure facial landmarks. Results were analyzed using paired t-test, setting the level of significance at p<0.05. There was no significant difference between the two methods but Knebelman’s method had less variability. Results suggest that Knebelman’s method should provide more reliability for determining VDO in all the facial biotypes studied.
