Palatal relief

[appledental]

Hi everyone. I have a doctor that wants me to do a palatal relief on a full upper appliance. What would i use for blockout during processing? Thanks for help.

Use to use tin foil back in the day. Kept a roll of that around for yrs.

Im sure you can get this anywhere if its what is still commonly used. Been along time since I did a full denture let alone palatal relief. Product Family Details

Tin foil is too thin. They make a relief metal. In a pinch or if you're not going to do a lot of these you can cut a piece of cardboard (not the corrugated kind) from your box of sheet wax and leave it covered with a small piece of plastipak (cellophane).

Plaster will work fine, leaves no edges to be concerned with, clean, and simple.

Except for that even thickness thing. especially when covering a tori. I always cut the relief metal at a bevel so edges are not a problem. Occasionally have to 'pleat' a relief for those really prominent tori.

Cynoclosure also posted a nice series of luckman postdam you might want to emulate. http://www.cynosuredental.com/wp-content/uploads/2010/01/luckmanpostdam.pdf
or another thread about relief and obtaining it.

My dad Joe Luckow showed me the luckman in 1967, don't know where he got it from.

i take pressure sensitive wax (as used for saddle relief in cast partial design) and apply to palate. Take sharp scalpel, and gently trim out shape of releif chamber, leaving clean edges around the opening. Slightly moisten model so that plaster mix will stick. Mix plaster and spread evenly into the cut-out. Allow to dry and then remove wax.
