Age Changes of Jaws and Soft Tissue Profile

Abstract

Age-related changes of jaws and soft tissue profile are important both for orthodontists and general dentists. Mouth profile is the area which is manipulated during dental treatment. These changes should be planned in accordance with other components of facial profile to achieve ultimate aim of structural balance, functional efficacy, and esthetic harmony. Through this paper, the authors wish to discuss age changes of the hard and soft tissues of human face which would help not only the orthodontists but also oral surgeons, prosthodontists, pedodontists, and general dentists.

Differences between male and female mandibular length growth according to panoramic radiograph

“…21 The research of a craniofacial post-pubertal growth in subjects aged 16,18, and 20 years using a cephalogram shows that the craniofacial growth from 16-18 years is greater than that of 18-20 years of age. 22 The average growth of mandibular in Danish male is about 3 mm at 16-17 years, and the growth declines until it reaches the state of no growth at the age between 21-22 years. 23 Based on Table 1, at the age of 25 (group C), the male mandibular length was ± 154.59 mm in the right side and ±153.74 mm in the left side, whereas female mandibular length was ±147.48 mm in the right side and ±147.47 mm in the left side.…”

Assessment of the Facial Profile: The Correlation between Various Cephalometric Analyses and the Soft Tissue Angle of Convexity

“…These include jaw profile field, H-line and the soft tissue angle of convexity [22][23][24][25][26] . There are many variations of soft tissue angle of convexity described in the literature [28][29][30][31] . The variant of soft tissue angle of convexity utilizing the glabella (G') is said to remain stable with age, as this is minimally affected by soft tissue growth [29][30][31] .…”

“…There are many variations of soft tissue angle of convexity described in the literature [28][29][30][31] . The variant of soft tissue angle of convexity utilizing the glabella (G') is said to remain stable with age, as this is minimally affected by soft tissue growth [29][30][31] . Hence, this parameter was used to evaluate the soft tissue profile in the current study.…”

Special Investigation of Developmental of Mandibular Asymmetry and Imbalance Body Posture: A Literature Review

“…The timing of the pubertal growth spurt is paramount in planning orthodontic treatment since the general growth and development influence orthodontic treatment prognosis. In human skeletal growth, the skeletal basis of the postural is usually developed at the same age as well as mandibular growth and development [1], [2]. The symmetry assessment becomes a key determinant for assessing expressions and attractiveness in psychology and anthropology nowadays, including facial and body posture.…”
