Dental impression tray with absorbent barriers

A method for obtaining a dental impression of maxillary and mandibular teeth of a patient, comprising:

• providing a dental impression tray comprising:
• a lingual edge member comprising a top surface, a bottom surface and an inner edge;
• a buccal edge member comprising a top surface, a bottom surface and an inner edge;
• a distal member, said buccal edge member and said lingual edge member being generally parallel and extending from the opposing ends of said distal member, said distal, lingual and buccal members in combination defining a support frame, said support frame conforming to a dental arch of a patient;
• a handle extending obliquely from said buccal edge member;
• a partially permeable membrane, said partially permeable membrane extending from said inner edge of buccal edge member to said inner edge of lingual edge member;
• a first trough defined by said partially permeable membrane, a first absorbent barrier member and a second absorbent barrier member, wherein said partially permeable membrane defines a base of said first trough, wherein said first absorbent barrier member defines a first wall of said first trough, and wherein said second absorbent barrier member defines a second wall opposite to said first wall of said first trough;
• a second trough disposed below said first trough, said second trough defined by said partially permeable membrane, a third absorbent barrier member and a fourth absorbent barrier member, wherein said partially permeable membrane defines said base of said second trough, wherein said third absorbent barrier member defines a first wall of said second trough, wherein said fourth absorbent barrier member defines a second wall opposite to said first wall of said second trough;
• said first and third absorbent barrier members extend from a top side and a bottom side of said buccal edge member along an entire length of said buccal edge member;
• said second and fourth absorbent barrier members extend from a top side and a bottom side of said lingual edge member along an entire length of said lingual edge member;
• wherein said first trough is configured to receive one or more of the maxillary teeth of a patient and said second trough is configured to simultaneously receive one roe more of the mandibular teeth of said patient;
• wherein all of said first wall and said second wall of said first trough are absorbent and all of said first wall and said second wall of said second trough are absorbent;
• wherein said support frame is composed of metal alloy, stainless steel or high density polyethylene.
• placing a dental impression material into said upper and said lower troughs;
• receiving a biting force from the teeth of a patient in said first trough and said second trough;
• curing said dental impression material.
