Functional Matrix Theory Of Growth | Orthodontics Lecture | Dr Manase

Watch the “Functional Matrix Theory Of Growth In Orthodontics” lecture presented by Dr Manase (Masters in Dental Surgery).

Why is this an important dental study video?

The functional matrix concept of Melvin Moss revitalized the studies of growth and development at the time when the sutural growth theory of Sicher and the cartilaginous growth theory of Scott were severely criticized for their inadequacy. Moss introduced the doctrine of functional matrix complimentary to the original concept of functional cranial component by Van Der Klaaus.

Since a major part of orthodontics treatment is attributed to the disproportionate growth of the jaws, it is important to know how the skeletal growth is influenced and controlled.
This dental lecture covers the evolution, functional matrix theory hypothesis and it’s significance.

An understanding of the functional matrix theory (Melvin Moss) will help us appreciate the etiologic process of malocclusion and dentofacial deformity.

Hoping this orthodontics lecture helps add some value
