A Clinical and Laboratory Comparison of Alginate Impression Techniques,
Abstract
A clinical and laboratory comparison of alginate impression techniques was undertaken. Rim-lock (trademark) trays were modified with a combination of modeling compound, wax, and alginate adhesive. Both the modified and unmodified trays were used to make alginate impressions of either standard laboratory maxillary and mandibular models or maxillary and mandibular arches of dental patients. The stone casts that were subsequently fabricated were evaluated with a measuring microscope and by ten dentists assessing the accuracy of fit of a prepared occlusal plaster index to the stone casts. It was determined that the most accurate stone models could be made from an alginate impression technique using a Rim-lock tray modified with modeling compound and an alginate adhesive. (Author)
