2. DIMENSION OF
DENTITION
The clinical practice has always been
based on the various Dimensions of
dentition-vertical, transverse, and sagittal
These dimension allows the teeth to move
in six directions :Mesially, distally,
facially,lingually,intrusively,and
extrusively
www.indiandentalacademy.com

3. All of these movements are limited and
restricted physical environment
Of bone, muscle, and soft tissue, all of which
exert an influence on the teeth and jaws.
so an efforts has been made to determine
the extreme limits of this environment.
It appears that each engineering change in
appliance fabrication brings about a new
challenge to the physical limitations of the
dentitions environment.

4. Dimensions of dentition include four basic
premises, provided that the musculature in
normal:
Premise 1: an anterior limit exist. the teeth must
not be placed forward of basal bone
Premise 2:an posterior limit exist. teeth can be
positioned distally off the maxillary tuberosity
and/or impacted in the the area behind the
mandibular first molar in the mandibular arch
just as easily as they can be moved too far
forward off basal bone.

5. Premise 3: lateral limit exist.
Premise 4: a vertical limit exist
Orthodontist must recognize the limitations
of the dental environment and design
treatment to conform to these dimensions
when normal muscle balance exist
