Hyalinization During Orthodontic Tooth Movement

Hyalinization During Orthodontic Tooth Movement

Question 1. Write short note on hyalinization.
Answer. If the orthodontic force increases more than the capillary pulse pressure, i.e. 20–26 gm/cm2 blood vessels get compressed or occluded.

“Understanding the role of hyalinization in orthodontic treatment”

• As PDL get compressed the blood supply of compressed area get cut off
• Now the cells which become activated osteoclasts remain inactive.
• A sterile necrotic area is visible in compressed PDL.
• This is when seen in light microscope appear as area devoid of cells and this is known as hyalinized area and process is known as hyalinization.
• Hyalinization is a reversible process.
• The effect of hyalinization is that it does not allow tooth to move.
• In hyalinization tooth can be moved in the condition in which bone beneath the hyalinized area undergo resorption.
• Hyalinization last for one to two weeks after which resorption occur by undermining resorption.
