Aging of the Mandible and Its Aesthetic Implications

Abstract

These results suggest that the bony elements of the mandible change significantly with age for both genders and that these changes, coupled with soft-tissue changes, lead to the appearance of the aged lower third of the face.

Normative Morphometry of Adult Sudanese Mandible: A 3D Computerized Tomography Based Study

“…[13] In each three studies; the mean of bigonial width in men was greater than in women. [13,14,15] DOI: 10.9790/0853-1507108287 www.iosrjournals.org 86 | Page…”

“…In contrast, many recent studies suggest that the bone aging of the facial bone is a process primarily of contraction and morphologic changes. [7,8,11]In a study which was carried out by Shaw et al on 3D CT images, it was revealed that there were no significant changes in bigonial width and ramus breadth across ages in both genders. Ramus height, mandibular body height and mandibular body length decreased with age for both genders and mandibular angle increased in both genders across ages.…”

“…The age related changes of bony morphology are not well defined. [6] Previous researches focused on changes in soft tissue and skin with aging but changes in bones and facial skeleton significantly affected the aging face [7] Any kind of changes in the mandibular projection, width, or height can affect the overall aesthetics. [8] Reshaping of the face with ageing is the result of volume changes and loss of support.…”

“…Ramus height, mandibular body height and mandibular body length decreased with age for both genders and mandibular angle increased in both genders across ages. [7] Raising the knowledge of mandible changes with age has been highly essential due to an increasing demand for facial treatment. The aim of this study is to characterize the mandible and to find out the norms and to study if there is age and/ or gender related deference.…”

“…De wangen vlakken af en gaan plooien en de nasolabiale plooi wordt dieper. De lippen lijken dunner door de afname van het lippenrood (Mohindra en Bulman, 2002;Pecora et al, 2008;Shaw et al, 2010). Omdat de huid meer gaat hangen en de spiermassa minder wordt, worden met de tijd de incisieven in de bovenkaak minder zichtbaar en de incisieven in de onderkaak juist meer.…”
