Relationship between malocclusion, soft tissue profile, and pharyngeal airways: A cephalometric study

Abstract Introduction: The great variance in soft-tissue drape of the human face complicates accurate assessment of the soft-tissue profile and it is a known fact that facial features of different ethnic groups differ significantly. This study was undertaken to establish soft tissue norms for Himachali ethnic population. Method: The sample comprised lateral cephalograms taken in natural head position of 100 normal subjects (50 males, 50 females). The cephalograms were analyzed by Arnett soft tissue cephalometric analysis for orthodontic diagnosis and treatment planning. The Student t test was used to compare the means of the 2 groups. Results: Statistically significant differences were found between Himachali males and females in certain key parameters. Males have thicker soft-tissue structures than females. Whereas females have greater interlabial gap when compared with Himachali males. When compared with other ethnic groups, Himachali subjects have thicker soft tissue structures. Conclusions: Statistically significant differences were found between Himachali males and females in certain key parameters. Differences were also noted between other ethnic groups and Himachali faces.

Cephalometric Study

Objective: This longitudinal retrospective cephalometric study was undertaken in an attempt to evaluate the effect of Class III activator on the soft tissue structures in subjects with skeletal Class III. Methods: The material consisted of cephalometric films of 26 Class III patients (13females and 13 males, with a mean age of 13.58±4.38 years). Each treated patient was matched before treatment with Class III subject for sex and age. Differences at T1 and T2 were examined using paired t-test. Results: After treatment the patients' soft tissue profile improved significantly compare with before treatment. Conclusion: Soft tissue changes were found in patients treated by Class III activator in skeletal Class III patients. Clinical relevance: Class III activator may be an efficient method to improving soft tissue facial profile in Skeletal Class III malocclusion.

The aim of this study has been to establish the values of soft tissue profile angles in subjects with dentoskeletal Class I, Class II Division 1, Class II Division 2, and Class III pattern, in order to examine the influence of sagittal dentoskeletal relation on the value of angular profile parameters. This comparative cephalometric study included the examination and the analysis by lateral cephalograms to evaluate soft tissue profile angles for 120 adult Caucasian subjects (60 women and 60 men) from the mid Balkan region divided into four groups towards ANB angle and incisors inclination. The following angles were examined: angle of facial convexity, facial convexity angle for the lower face and the angle of total facial convexity. By investigating the influence of the sagittal dentoskeletal pattern on the value of facial convexity angles, significant differences have been established between subjects with Class I and Class II Division 1 and 2 for all examined angles (p<0.001; p=0.011), while the differences between Class I and Class III are only significant for the facial convexity angle and facial convexity angle for the lower face, while the differences in the overall facial convexity angle are not significant (p=0.067). There are significant differences between subjects for all examined angles except the total facial convexity angle between Class I and Class III.

Cephalometric Study

In orthodontics, various methods of assessing sagittal jaw base relationship areformulated.Earlier, skeletal pattern was analysed only clinically, with the introduction of Cephalometrics by Broadbent and Hofrath in 1931, ANB angle and Beta angle are being used to describe skeletal discrepancies between the maxilla and mandible. YEN angle is also used as a sagittal dysplasia indicator after its introduction in 2009. The aim of our study was tocorrelate ANB, Beta and Yen angle with soft tissue profile angle in class I and class II patientsTotal of 140 lateral cephalograms of class I and class II patients were selected based on soft tissue profile angle. In each cephalogram, ANB, Beta and YEN angle were measured and compared with soft tissue profile angle. Statistical analysis carried out. Our study concluded that soft tissue drape in both Class I and class II individuals are not significantly correlated with skeletal alignment of maxilla and mandible.
