In the year 1972, they explained a simple technique of
fabricating a single- piece, hollow obturator prosthesis.
Tanaka et al.(13) in 1977 simplified the fabrication
process for a light weight obturator. They felt that using
polyurethane foam as core to reduce the weight of the
obturator would be efficient and economical. Parel and
LaFuente(14) in 1978 formed a hollow prosthesis in single
visit. First a resilient liner material was adapted to the
defect on all surfaces except at the palatal side. This was
then filled with sugar to the level of the palate.
Autopolymerizing resin was used to form the lid for the
palatal side. Sugar was drained later through a small bur
hole on the lid, which was sealed with more
autopolymerizing resin. Beder and Todo(15) in 1978
explained yet another rapid technique for constructing a
hollow bulb.
They used hollow plastic forms of different shapes and
sizes, which were modified according to the requirements.
They were enclosed in autopolymerizing resin to form to
forms the walls of the defect. Phankosol and Martin(16) in the
year 1985 developed a technique for constructing a hollow
obturator with a removable lid combining the benefit of both
closed and open hollow obturators. In the present case bulb
was fabricated with heat cured acrylic resin, as the unreacted
monomer being less in heat polymerized acrylic resin and
risk of its leaching is also reduced.
