HISTORY
3000 B.C
60 MILLION YEARS AGO INSECT WAX USED TO BE A DIET SOURCE
GREEK AND ROMAN
HISTORY• Matthaeus Gottfried Purmann in 1700 used
wax as models for prosthodontic purpose.• 1711 – Matthaeus Gottfried Purmann,first to
use bee wax as a impression material• The English term 'wax' is derived from the
• For gold, chrome, acrylic , partial or full palates
• Improves denture quality by obtaining natural living tissue finish , beautiful esthetics and greater comfort
• Less waxing and finishing (saves hand waxing)
• Convenient to use
