What is the functional matrix theory of growth?
In summary from, the functional matrix hypothesis explicitly claims that the origin, growth and maintenance of all skeletal tissues are always secondary, compensatory and obligatory responses to temporally and operationally prior events or processes that occur in specifically related non-skeletal tissues, organs or …
What is Moss functional matrix theory?
Moss wrote that “bones should not be considered as the named entities of classic osteology (e.g., a mandible or a maxilla), but rather as a series of segments, related to specific functions and responding, during their growth, to specific functional demands” [1] which became known as the functional matrix theory.
What is functional matrix?
In this form of organization, the functional manager retains most of the power; they “own” the people and resources. In a weak / functional matrix, the project manager is not very powerful. Usually they carry out an administrative or coordinating role and rely on the functional manages to get things done.
What is Servosystem theory of growth?
The Servosystem theory of growth is based on a factorial qualitative analysis which takes into account various factors which determine a coordinated growth of the craniofacial complex as a whole. The Servosystem theory attempts to explain craniofacial growth and the modus operandi of Functional appliances.
What is Moss hypothesis?
The fundamental basis for this hypothesis, laid out by Columbia anatomy professor Melvin Moss is that bones do not grow but are grown, thus stressing the ontogenetic primacy of function over form.
What is a functional matrix structure?
Matrix structure is a type of organizational structure where employees are grouped concurrently by two different operational dimensions. Functional structure divides the organization based on specialized functional areas such as production, marketing, and sales for the purpose of management.
What are the advantages of Projectized organization?
Advantages of the Projectized Organization Structure Clear line of authority. Strong communication with single reporting system. Flexibility in trade-offs and decision making. Fast decision making.
Who proposed nasal septum?
Theories of human midfacial development The first, proposed by Scott,1 suggests that the cartilaginous nasal septum is a primary growth centre that pushes or thrusts the midfacial bones downward and forward.
What is cortical drift?
Cortical Drift: – Most bones grow by interplay of bone deposition & resorption . – A combination of bone deposition & resorption resulting in a growth movement towards the deposition surface is called “Cortical Drift”.
Who is the founder of functional matrix theory?
FUNCTIONAL MATRIX THEORY (MOSS 1960) PROFFIT Moss says if neither bone nor cartilage were determinant or growth of craniofacial skeleton, the control would lie in the adjacent soft tissues. 21. He theorizes that growth of the face occurs as a response to functional needs and is mediated by the soft tissues in which it is embedded.
What are the two types of functional matrix?
The functional matrix includes muscles, nerves, teeth, glands, blood vessels etc. 26. Two types of functional matrix are recognized – Periosteal – Capsular The growth of functional matrix is primary; the growth of skeletal unit is secondary.
How are capsular matrices related to functional growth?
Capsular matrices act upon functional cranial components as a whole in a secondary and indirect manner. They do so by altering the volume of the capsules within which the functional cranial components are embedded. The effect of such growth changes is to cause a passive translation of these cranial components in space.
Is the alveolar bone also a functional matrix?
Teeth are also a functional matrix, as the experience of every dentist can attest empirically. Indeed, most orthodontic therapy is based firmly on the fact that when this functional matrix grows or is moved, the related skeletal unit (the alveolar bone) responds appropriately to this morphogenetically primary demand.
