The secret behind the system rests in the unique relationship between the two impression materials. The irreversible hydrocolloid Tray and Syringe gels have different viscosities, but are chemically compatible and designed to work harmoniously in the mouth to create impressions with outstanding accuracy and detail.
The light bodied thixotropic syringe gel is fluid yet resists slumping making it ideal for both dentate and edentulous impressions. For the edentulous patient the syringe gel can be conveniently placed into the peripheral border areas using the AccuDent XD Syringe delivery system. For the dentate patient a specially designed tip is attached to the syringe to facilitate the capturing of detail of the dentition and surrounding gingival area.
The highly viscous Tray Gel supports the Syringe gel in the mouth as it forms a “custom tray” directly in the patient’s mouth. Applied correctly, the “zeroflow” Tray Gel does not flow down the patient’s throat, greatly reducing the gag reflex and promoting a more accurate impression.
"With its launch, the new AccuDent XD Alginate Impression System will become a terrific addition to our impression system portfolio," says Dr. Frank Lauciello, Director of Removable Prosthodontics Ivoclar Vivadent. "The ease of use, consistency, and the accuracy of the material allows for the creation of better impressions, which translates into a superior final restoration.”
The AccuDent XD Impression System creates dimensionally accurate impressions free of air bubbles and voids, making it possible to create visibly better primary stone or virtual models. These impressions are highly desirable for the fabrication of complete and partial dentures, whitening trays, mouthguards, orthodontic appliances and opposing models.
