Obturators are an integral part in Post-surgical management
of Maxillectomy patients. There are several techniques
and materials used for taking impression in the
post-surgical phase, but the choice of materials for fabrication
of Obturators and the defect portion are Acrylic
resins and Soft liners. Poly Vinyl Siloxane (PVS) is one of
the best-known accurate impression materials with good
short-term Biocompatibility, however its use as a delayed
surgical obturator has not been validated till date. There
is no literature to substantiate its long-term effects of Biocompatibility.
Hence the aim of the study is to evaluate
long-term
