  • 31.  Subtelny [AJO 1959;45:481-507], - first demonstrated downward and forward growth of mandible during maturity. -nose grows more vertically when compared to its growth in sagittal dimension.  Meng etal [AJO1988 ], -Supported the subtelny conclusions WWW.INDIANDENTALACADEMY.COM
  • 32.  Scott [Br.Dent J 1953;95:37-43], - Nasal septum is determinant of midfacial growth  Lathum [J Anat 1970;107:47-78], -nasal septum acted as a starter mechanism ,pulling the premaxillae and maxillae forward via the so called septo-premaxillary ligaments WWW.INDIANDENTALACADEMY.COM
  • 33.  Grymer et al [Rhinology 1997;35: Abstract], - Deficient nasal septum growth along with decreased anteroposterior growth of the maxilla leads to an upward displacement of the anterior part of the maxilla indicating a strong relationship between nasal growth and inclination of the maxillary plane. WWW.INDIANDENTALACADEMY.COM
  • 34.  Robinson et al [AJO 1986;89:499-506], -Their cephalometric study on the relationship between skeletal facial pattern and soft tissue nasal form concluded that nasal shape followed the underlying skeletal pattern very closely in the sagittal dimension. WWW.INDIANDENTALACADEMY.COM
  • 35.  Peter H. Buschang [JCO 1992;26:111-118], -Horizontal growth at pr and sn is closely associated with horizontal growth at ANS and A POINT WWW.INDIANDENTALACADEMY.COM
  • 36. CONCLUSION WWW.INDIANDENTALACADEMY.COM
  • 37. -Nasal length was seen to be significantly correlated to upper anterior facial height and inclination of palatal plane. -An upturned nose in an adult individual was significantly correlated with anti-clockwise rotation of maxilla. WWW.INDIANDENTALACADEMY.COM
  • 38. -SIgnificant correlation is present between nasal projection and nasal length with sagittal maxillary dimensions. WWW.INDIANDENTALACADEMY.COM
  • 39.  Growth and development of any structure will occur in three dimensions of space simultaneously and the overlying integument adapts in three dimensions.so,its wise to understand the concept in three dimensions of space than analyzing in one or two dimensions. WWW.INDIANDENTALACADEMY.COM
