The study was carried out on six patients with acquired maxillary defect (class I aramany's classification) who are in need of definitive obturator. This study was done to compare the microbial colonization of heat cured acrylic resin and versacryl in obturators restoring acquired maxillary defects. Selected patients received a metal framework prosthesis with heat cured acrylic resin bulb extending into the surgical site. At time of delivery after complete adjustment and relief were done, a swab was obtained from the patient's mouth from the nasal surface of the surgical defect which represents the base line for this group. Another swab was taken after two and four weeks from wearing the obturator for microbiological evaluation and the swab was taken each time from the same place. The heat cured acrylic bulb was replaced with versacryl and the same steps were carried out as the heat cured group. Swabs were immediately cultivated into three different media blood agar, Sabouraud dextrose agar and macconkey media and incubated for microbiological evaluation. The identification and quantification of the isolated microorganisms were performed using conventional microbiological cultivation method
