Consultants’ Comments

• “I really like the color contrast – the margins were easy to read.”
• “Assistants found the putty easier to mix than other brands.”
• “Small tips make intraoral extrusion difficult.”
• “The light-bodied consistency stays in place but registers margins well.”
• “Impressions separate easily from their models.”
• “The light-bodied consistency has excellent detail and appears to have good tear strength.”

Description

ELITE H-D+ Impression System is an addition silicone impression material that includes a variety of viscosities and two setting times. It features particles with nanometric size and structure in all viscosities to obtain a silicone-nanoparticle combination. The presence of the nanostructure is reported to increase the fluidity of the material, particularly when pressure is applied. All viscosities exhibit a snap set that helps reduce inaccuracies that may occur from movement during setting of the impression. The light, super light, regular body, monophase and tray materials are available in 50-ml automix cartridges in a normal and/or fast set. Monophase and Tray material are also available for use with the Pentamix system. Putty is available in a normal and fast set in 250-ml and 900-ml tubs of base and catalyst. The Intro kit contains the dispensing gun, and mixing and intraoral tips. The working time for normal set is two minutes and setting time is five minutes. The working time for fast set is 1:30 minutes and setting time is four minutes. Twenty-three consultants evaluated ELITE H-D+ Impression System in 373 clinical applications.

Product Features

Dispensing all viscosities of ELITE H-D+ Impression System from the automix cartridges is consistent and does not require excessive pressure. The light-bodied consistency was rated very good and exhibited good flow around the prepared teeth without slumping. Both the normal set and the fast set have sufficient working times, while the setting times vary from four minutes for the fast set to 5:30 for the normal set. When an impression of multiple preparations is needed, the normal set is a good option. Any combination of the viscosities is easily removed from the mouth and all show good tear resistance even in thin sections. Visualizing margin detail is simplified by the excellent color contrast of the different viscosities. The fit of the resultant restorations was judged to be very good. Eighty-seven percent of the consultants rated ELITE H-D+ Impression System equivalent to or better than the material they were currently using and 78% would recommend it.

Clinical Tips

• The putty requires mixing with washed hands or using non-latex gloves.
• If the provisional restoration is fabricated before making the impression, completely remove all residue from the teeth. Any acrylic residue could inhibit the setting of the material.
