* Optimize occlusion
* Best possible masticatory function
* Breathing
* Speech

Question 3

Occlusal function enhancement: what must be established/ corrected?

Answer 3

• Establish harmonious occlusal relationship in the three planes of space
• Establish anterior coupling
• Correct Antero posterior and vertical discrepancies
• Establish or normalized the transverse dimension

Question 4

how is ortho an Interdisciplinary care?

steps?

Answer 4

• Involves several specialties of dentistry
• Requires careful panning
• Start with the end in mind

  in occlusion with the buccal
  groove of the lower first molar
  and a full complement of teeth
  is present ”. (second half not true)
