Antagonism, meeting, gliding of teeth. This is how the teeth are meeting up with the opposite/antagonist. The dynamic concept is not existing yet in this period.

The standard of normality of the dental arch is a curved line expanding as it approaches the ends, and all teeth standing on that line.

His concept of normal occlusion as a historical event, possible only with a throwback to our primitive ancestors

In 1899, Angle described the _______________ skull to exemplify normal occlusion.

A smooth curved line that is passing along the fossa of the posterior teeth and across the cingulum of the upper anterior teeth.

A smooth curved line that runs along the buccal cusps of the posterior teeth and the incisal edges of the anterior teeth.

A person who opposes Angle, questioning the Old Glory skull of Angle.

Case questioned Angle for considering ____________________ as normal.

His concept of occlusion refers to closure of teeth upon the other.

He used plaster casts of the face and teeth in anthropologic manner.

�Normal position of rest of mandible is with the teeth slightly separated (freeway space), but with lips easily closed”. First functional analysis or dynamic approach to occlusion.

	Bennett noted that condylar movement was primarily ____________ on opening and after passing this point, it becomes ________________.

Broadened the concept of occlusion by relating the teeth to the rest of the face and cranium

He introduced mastication as part of definition of occlusion

Famous for the orbital plane.

Passes through the distal third of the canine. No foundation at all.

In orthodontic diagnostics it is a technical procedure for orienting the dentition to certain cranial landmarks

Known for his contribution in growth and development. There is racial variation in normal occlusions.

Broadbent introduced what?

For the first time they were able to follow longitudinally the orofacial development. Measuring at different time points. Cross section is a one-time measurement.

�Mere occlusal contact is not enough, efficiency of masticating system. Occlusion is interdigitation of teeth plus the status of controlling musculature and functional factors”.

With the concept of Planer, the factual period could be said as the?

What is the third element of occlusion?
