Age related changes of mandible and maxilla in human (Morphometric study)

Abstract

The properties of bones change during life and with age, it may improving in function,,but in some times function deteriorates. Throughout development and aging, bone shape alters in response to load. This study provide information on the development and normal growth of dental arches in both sex. Forty adult person of both sex were used. They divided in to 4 groups (A, B, C, and D). We will use different size of trays and take alginate impression material to get anatomical impression for the upper and lower jaw from the male and female and obtained a dental cast which is identical to the dental arch and make a table for all measurement that acquired. The results showed that the age have a reliable degradation effect in both sex specially after 40 years old and except in the transverse measurement of female in mandible which started to decline after 30 years excluding the inter canine width which decrease after 40 years.
