Understanding Freeway Space And Its Role In Occlusion

Question 1. Freeway space
Answer:

• During rest position, space exists between the upper and lower teeth
• This is called freeway space

Freeway space Value:

• It should be 2-4 mm

Freeway space Significance:

• If it increases, the vertical dimension at occlusion reduces and becomes inefficient
• If it decreases, the vertical dimension at occlusion increases to a great extent

Question 2. Odland bodies
Answer:

• It is a small organelle formed in the upper spinous and granular cell layer
• It is a coating granule, glycolipid in nature
• It has an internal lamellated structure

• This barrier is formed between granular and cornified cell layers
