Abstract
This invention discloses a new dental impression tray that is adjustable without a clamping means. The single sized tray serves for all the different arch size configurations. Most tray fitting problems arise in adaptation in the posterior segment. This tray is simply spread apart to adapt to size of arch and used directly with no clamping or fixation. The newly adjusted tray's shape is maintained by only the integrity of the outer wall.
