Currently running into retention issues when designing splints and other appliances.

Wondering if anyone has a set of parameters for retention/offset that works for them consistently?

Thanks!

I do a block out of 0.5 mm of retention and design the internal shell with 0.1 mm offset (Default). I find doing the block out separately gives more control and you can add/remove wax in areas as you will.

I don't have any issues, however i am using a thermal/semi thermal material so we ere on the side of more retention. With Hard acrylic with ball clasp designs i run 0.3 mm block out and manually carve the sections of ball clasps prior to design.
