A dental impression tray having a handle and a mouthpiece is disclosed herein. The mouthpiece contains an upper portion and a lower portion defined as a means for laterally displacing excess impression material. The upper portion of the mouthpiece, which holds the impression material, is defined by outer and inner walls having arcuate shapes, a base attached to and extending the length of the bottom of the outer and inner walls, a plurality of elongated vent holes in the base, and a serpentine occlusal stop ridge extending from the top of the base. Therein the outer edge of the inner wall of the upper portion of the tray are a plurality of holes which force excess impression material to extrude to the means for laterally displacing excess impression material. Excess impression material extruded from the holes flow laterally across the horizontal surface and interlock with the excess material extruded from the elongated vent holes thereby securely attaching the impression material to the mouthpiece. Moreover, the elimination of the palate on the impression tray which creates the impression of the upper dentition by the present invention decreases the likelihood of inducing a patient's gag reflex.

A mandibular advancement splint provides for adjustable lateral movement of upper and lower appliances. An upper appliance is inserted onto a user's upper jaw and a lower appliance is inserted onto a user's lower jaw. A first protrusion is formed on the upper appliance. A second protrusion is formed on the lower appliance. One of the first protrusion and the second protrusion can be adjusted to offset the lower jaw with respect to the upper jaw.The splint can have an upper appliance having a body mounted to an upper jaw of a user; and a lower appliance having a body mounted to a lower jaw of a user. The upper appliance has a pair of adjustable wings attached to the upper appliance body; and the lower appliance has a pair of fixed wings attached to the lower appliance body. The pair of wings attached to said upper appliance are slidably adjustable with respect to the upper appliance body to determine the offset between the upper and lower jaws of the user.

An extracoronal attachment for a removable partial denture utilizes a joint comprising a fixed ball within a movable resilient tube to connect the prosthesis to the abutment teeth. The attachment is accurately constructed by a kit and applied by a method which insures that tensile and shear stresses otherwise applied to such attachments during functional loading are significantly reduced so that the male retainer may be permanently secured to the abutment teeth by means of an adhesive bond.
