Elastic Force Difference 9.5mm vs. 6.4mm for Reverse Headgear Protraction Facemask

0 Rating(s).


Posted on By K French In Orthodontics

My child recently started orthodontic treatment with a reverse headgear protraction facemask.

We were originally provided 4.5 oz, Medium, Size 3/8" 9.5mm latex elastics with the facemask.

After using these latex elastics for a few days some irritation developed on the inside of lips. It was suggested we try a latex free elastic to see if that would solve the irritation issue.

Our orthodontist, provided latex free alternative elastic in the following size: 4.5 oz, Medium, Size 1/4" 6.4 mm latex free elastic.

Upon waking up the morning after using the latex free elastic, my child was feeling considerable pain in his teeth and jaw.

Would the latex free elastic in 4.5 oz, Medium, Size 1/4" 6.4 mm produce significantly different forces VS. the 4.5 oz, Medium, Size 3/8" 9.5mm latex elastics?

If yes - is there anything we should be concerned about? (only wore the smaller latex free elastics for just the one night).

Thanks!

Some latex is allergic. It depends on the patient's body features. You may have to consult it with a specialist
