Oral Stereognosis in Completely Edentulous Patient With Maxillary Tori

Six test pieces were selected from the 20 shapes of test pieces from National Institute of Dental Research. The test pieces comprises of 6 shaped forms which include circle, plus, square, rectangular, triangle and toroid shaped. A 2mm stainless steel wire was bent forming the test piece shape following the standard dimensions (13mm length and 2mm thickness)as described by National Institute of Dental Research to serve as the test pieces mould. Using the six test piece moulds, light cured acrylic resin test samples were fabricated. The test samples were trimmed and polished to meet the standardized measurements. A total of 240 test sample (6 samples for each patient) for 20 completely edentulous patients with maxillary tori and 20 completely edentulous patients without tori were made for the study. The test pieces were attached to dental floss to prevent any accidentally aspiration during the study.
