The Accu-Dent System 2 is a new impression system for removable partial dentures. The system uses the Accu-Gel impression materials, which are chemically compatible, irreversible hydrocolloid impression materials that differ in viscosity. The low-density (syringe) material is injected into the vestibular and dentate areas while the high-density (tray) material is used in the tray to support the syringe material and form a type of "custom tray" in the mouth. The system comes with special, autoclavable, plastic, perforated impression trays that Ivoclar Vivadent claims can be easily modified for special cases. The Accu-dent impression materials are said to be also indicated for immediate dentures, orthodontic impressions, athletic mouthguards, occlusal splints, and bleaching trays.
The Accu-gel impression materials met ANSI/ADA requirements for alginate materials and exhibited acceptable working and setting times. Clinical evaluators reported that the material was easy to mix and dispense and had acceptable working and setting times. Patients tolerated it well, in part because it did not flow out of the trays as much as traditional irreversible hydrocolloids. Clinical users found the impression trays very useful and appreciated their customized design which made it easier to make successful impressions. The Accu-Dent System 2 was found to be excellent for making removable partial denture final impressions and in the fabrication of nightguards and obstructive sleep apnea appliances. The easy-to-read, complete instructions contained adequate detail and the packaging for the system was compact and easy to store. The main disadvantage of the system is that it is much more expensive than traditional hydrocolloid materials.
