Difference Between Natural and Artificial Occlusion :
1) The teeth in natural dentitions are retained by periodontal tissues that are uniquely innervated and structured. In complete artificial occlusion all the teeth are on bases seated on slippery tissues.
2) In natural dentitions the teeth receive individual pressures of occlusion and can move independently.
3) Malocclusion of natural teeth may be uneventful for years.
4) Non vertical forces on natural teeth during function affect only the teeth involved and are usually well tolerated, whereas in artificial teeth the effect involved all of the teeth on the bases. It is usually traumatic to the supporting structures.
5) Incising with the natural teeth does not affect the posterior teeth. Incising with artificial teeth affects all of the teeth on the base.
6) In natural teeth the second molar is the favored area for masticating hard foods.
7) In natural teeth bilateral balance is rarely found; if present it is considered balancing side interference.
8) In natural teeth proprioception gives the neuromuscular system control during function.
