What is more incisally than those of the posterior teeth?
400
Any deviation from ideal positioning of the teeth, whether it is a minor deviation of one tooth or a severe variation involving several teeth or jaws, creates

400
Occurs when the maxillary and mandibular teeth contact each other in any functional relationship
What is occlusion?
400
An existing space between the mandibular and maxillary teeth

What is proximal contact area?
400
Their main use is in the construction of dentures or in the balancing of the arches for orthidontia
What is compensating curvatures?
500
A deep or vertical overlap of the maxillary teeth onto the mandibular teeth that exceeds the normal, or one-third the depth of the mandibular incisors
