  • Objective: To evaluate 4 interocclusal recording materials for their ability to reproduce accurately interocclusal relationships after a storage time of 1 or 48 hours. Method and Materials: A custom-made metal apparatus was used to simulate the maxilla and mandible. The vertical discrepancies were measured by a precision dial gauge. Eight interocclusal records were made in each of the following groups: (G1) Futar D (polyvinyl siloxane; Kettenbach), (G2) Ramitec (polyether; 3M ESPE), (G3) LuxaBite (composite resin based on bisacryl; DMG), (G4) Aluwax (aluminum wax; Aluwax Dental Products), (G5) LuxaBite corrected with LuxaBite, and (G6) LuxaBite corrected with Aluwax. The vertical discrepancies were measured after storage of the records for 1 and 48 hours at room temperature and repositioning of the records in the metal apparatus. Data were statistically analyzed using 1-way analysis of variance followed by the Games-Howell test
