My wife recently had her braces off and was fitted with day and night clear plastic retainers to use for the next year, and one of them needs repair/replacement. This was on the other side of the world, so returning to the same orthodontist is impractical. Does anyone know of, or have experience with any dentists/orthodontists in the CM area that use this modern method as opposed to the old, hard, metal retainers?

I had a dental implant started in the U.S., with the final crown done here. Dr. Tongnard 053-277-405, he's over by the intersection of Suthep Rd. and Klong Cholapratan, not far from CMU. Really good job, has access to all the modern equipment/parts, etc.
