DEFINITION
‘The simultaneous contacting of the maxillary and mandibular teeth on the right and left side
and in the posterior and anterior occlusal areas in centric and eccentric positions, developed to
lessen or limit tipping or rotating of the denture bases in relation to the supporting structures”-
GPT
Types of Balanced Occlusion
Unilateral Balanced Occlusion
This is a type of occlusion seen on occlusal surfaces of teeth on one side when they
occlude simulatenously with a smooth, uninterrupted glide.
This is not followed during complete denture preparation. It is more pertained to fixed
partial dentures.
Bilateral Balanced Occlusion
This is a type of occlusion that is seen when a simultaneous contact occurs on both sides
in centric and eccentric positions.
Bilateral balanced occlusion helps to distribute the occlusal load evenly across the arch
and therefore helps to improve stability of the denture during centric, eccentric or
parafunctional movements.
Protrusive balanced Occlusion
This type of balanced occlusion is present when mandible moves in a forward direction
and the occlusal contacts are smooth and simultaneous anteriorly and posteriorly.
There should be atleast three points of contact in the occlusal plane.Two located
posteriorly and one anteriorly.Absent in natural dentition.
Posterior contact during protrusion to maintain balance (FIG below)
, Lateral Balanced Occlusion
In lateral balance there will be a minimal simultaneous three point contact present during
lateral movement of mandible.
This is absent in natural dentition.
Teeth should be arranged such that there is simultaneous tooth contact in balancing side
and working side.
Canine guided disocclusion. This relation is seen
in natural occlusion .
Anterior and posterior tooth contacting during
laterotrusion seen on working side.
