Abstract: | A master cast representing a completely edentulous mandible was fabricated in polyurethane resin and had four implants secured to the anterior interforaminal area. Impressions were made using six technique-material combinations. Ten definitive casts were fabricated for each technique. Linear distances between implants were measured using a traveling microscope. There was no statistically significant difference between the direct unsplinted and splinted techniques (P > .05), while the indirect technique was statistically significantly different from the other two techniques (P < .05). There was no statistically significant difference between the two impression materials. |
