“…This indicates that both maxillary and mandibular incisors tend to slope more posteriorly with increasing vertical jaw spacing.The therapeutic goal of the jaw movement approach is to reverse some of the alveolar compensation, restore the underlying skeletal base to its normal position, and normalize its relationship to each other and to the cranial base (De Clerck HJ, Proffit WR, 2015). 24 25 found a negative correlation with upper and lower incisor inclination when not accompanied by increased growth. Therefore, treatment planning must consider corrections for all three spatial levels.…”

: To assess the position and inclination of upper and lower incisors and bases in different groups of skeletal malocclusions. 45 pretreatment lateral cephalometric radiographs were included. They were divided into his three groups of skeletal class I, class II, and class III. A variety of linear and angular measurements were used to assess both the position and inclination of the maxillary and mandibular bases, incisors, and the relationship between the incisors. There was a significantly stronger correlation between anterior-posterior skeletal mismatch and maxillary alveolar bone compensation in skeletal classes I, II, and III. Except for maxillary vertical skeletal discrepancy (MP-SN) and alveolar compensation, there was a weak correlation between maxillary and mandibular vertical skeletal discrepancy and alveolar compensation. The anterior-posterior position of the skeletal jaw had a greater effect on alveolar bone changes than the vertical inclination of the skeletal jaw in the Grad variant. There may be a relationship between alveolar bone changes and skeletal anteroposterior and vertical position, inclination and intermaxillary relationship.

Excessive vertical inferior surface development combined with increased molar eruption was associated with vertical prefrontal basal and alveolar height Modi et al (2013).…”

“…There are several studies evaluated the dentoalveolar compensation in different vertical patterns (19,20,30) The correlation with maxillary and mandibular incisors position was not addressed in any previous study. For the negative correlation between maxillary and mandibular inclination with vertical patterns, Kuitert et al (20) found the same findings in both short face and long face group while Modi et al (19) found the same negative correlation with mandibular incisors inclination and no significant correlation with maxillary incisors inclination.…”

“…An alpha value of 0.05 and a power of 90% were considered. The calculation was based on a previous study conducted by Freudenthaler et al (3) in which the mandibular incisors inclination to MP line was 94±10° for Class II and 82.5± 5.8° for Class III malocclusions, respectively and another study conducted by Modi et al (19) in which the mandibular incisors position to NB line was 31.45±7.69mm for hyperdivergent face and 26.15 ±6.62mm for hypodivergent pattern, respectively. Power analysis indicated that 15 patients in each skeletal Class and 51 patients in each facial pattern were needed.…”

“…It is evident that angular measurements are less reliable in hyperdivergent face, so it is preferred that cephalometric analysis should base on both types of measurements (16-18). There are serval studies in orthodontic literature having the same aims (2,9,19-23), but comprehensive evaluation in anteroposterior and vertical in both position and inclination was not addressed yet. The aim of this retrospective study is to evaluate the position and inclination of maxillary and mandibular incisors in adults with different anteroposterior and vertical skeletal malocclusions.…”

BackgroundTo evaluate the position and inclination of maxillary and mandibular incisors in adults with different anteroposterior and vertical skeletal malocclusions.Material and MethodsIn this retrospective study, lateral cephalometry of 272 adults (134 males and 138 females) who met the selection criteria were digitally analyzed. They were classified based on both linear and angular measurements, anterioposteriorly into skeletal Class I, Class II and Class III and vertically into hypodivergent, normodivergent and hyperdivergent individuals. Sixteen linear and angular measurements were used to assess both positions and inclinations of maxillary base, mandibular base, maxillary incisors, mandibular incisors, and inter-incisors relationship. Descriptive statistics were calculated and presented. The intra-class correlation coefficient (ICC) was applied for the reliability of measurements. Pearson correlation was used to present the degree of correlation between all variables. A P value of < 0.05 was considered significant.ResultsThere was a significant correlation between anteroposterior skeletal discrepancy and maxillary and mandibular dentoalveolar compensation (P<0.001). There was significant correlation between vertical skeletal discrepancy and maxillary and mandibular dentoalveolar compensation except for maxillary incisor position. Anterioposterior skeletal jaw position had greater significant effect on the dentoalveolar changes than the vertical skeletal jaw inclination did with variant degree.ConclusionsThere may be an association between dentoalveolar changes and the skeletal anteroposterior and vertical positions, inclinations and intermaxillary relation. Key words:Dentoalveolar compensation, anteroposterior, vertical, skeletal malocclusions, Cephalometry.

BACKGROUND A deep overbite may be due to an underlying skeletal or dentoalveolar component that may influence the treatment plan. The purpose of this study was to evaluate and compare the different components of deep bite malocclusion and normal occlusion. METHODS This was a case control study. Lateral cephalograms and study casts of normal (N = 50) and deep overbite (N = 50) subjects were used to evaluate skeletal and dentoalveolar components. Data was analysed statistically by independent t - test. RESULTS The significant skeletal contributing factors were gonial angles, mandibular plane, maxillary plane angle & ramus / Frankfort horizontal. An increased curve of Spee and decreased mandibular first molar height were predominant dental variables in the deep overbite group. The inclination of the upper incisors & lower incisors height did not show a statistically significant difference between the two groups. CONCLUSIONS The counterclockwise rotation of the mandible and the increased curve of Spee were the dominant features of deep bite malocclusion. This analysis of deep overbite components could help clinicians design individualised mechanotherapy based on the underlying cause rather than being prejudiced toward conventional mechanics when correcting with a deep overbite malocclusion.
