Found this blurb in the International Journal of Prosthodontics:
Microwaving dentures for 6 minutes at 650w either sterilized or promoted the disinfection of the appliances. Inserting the denture in a plastic autoclave bag avoided both sparks and scorching of the base material.
(my summary)
Hmmm, not sure that I will recommend this technique yet, due to its inherent dangers.
