What is impregum used for?

Impregum Penta Soft is a less rigid, soft polyether impression material used to make dental impressions. This particular product is easier to remove and provides better initial hydrophilicity than other VPS products.

What type of material is impregum?

polyether impression material
Impregum Penta Soft Medium Body is a medium bodied consistency polyether impression material and is used with the mixing device Pentamix (also manufactured by 3M ESPE). This material is packed in bags that are sealed with a PentaMatic sealing cap.

How long does it take for impregum to set?

Impregum Super Quick Material is the ideal solution for impressions for 1 to 2 units. They offer an adequate working time of 45 seconds for these indications. The setting time in the mouth is 2 minutes.

Is impregum a polyether?

The first and only superfast Polyether that combines intrinsic hydrophilicity and snap-set curing with a better taste, a better smell and accelerated setting times.

What is polyether impression material?

Polyether impression material is an elastic-type material, as are the polysulfide and silicone materials. These materials have demonstrated good accuracy in clinical evaluations and are thixotropic, which provides good surface detail and makes them useful as a border molding material.

What is polysulfide used for in dentistry?

Use of Polysulfide Impression Materials. – Polysulfide impression material is often used with custom trays to increase the accuracy of the impression. preparation, and heavy-body material is used in the tray. – Light and medium-body materials are used for full- denture impressions.

What is a polyether impression material?

What is reversible hydrocolloid used for?

Sears introduced reversible hydrocolloid in 1937. This material has been considered the standard for dental impressions because a casting made from one impression will fit the die from a second impression. Agar hydrocolloid materials are derived from reversible agar gels.

What is polysulfide sealant?

Polysulfide sealant is a type of sealant designed for joints that are required to withstand prolonged immersion in liquids. Generally, this type of sealant is used for swimming pools, fountains, cooling towers, fuel, and chemical storage tanks, wastewater treatment, and petrochemical plants.

What is the disadvantage of using a polysulfide material?

potential for significant distortion. odor is offensive. messy & stains clothes. second pour is less accurate.

What is the difference between polyether and polyester?

Both polyester and polyether urethanes perform well at high temperatures. But polyesters are better able to withstand high temperatures longer and are more resistant to heat aging. Polyethers are less susceptible to dynamic heat build-up.

What is PVS impression material?

[1] The most popular elastomer used in the dental practice today is the polyvinyl siloxane (PVS). PVS impression materials have low dimensional change, low creep, and relatively short setting time, have moderate to high tear resistance.

What are the two types of hydrocolloids?

Two types of hydrocolloid are available: agar hydrocolloid and alginate hydrocolloid. Agar hydrocolloid is fluid at high temperatures and is solid at low temperatures. It is called a reversible hydrocolloid, since it can be changed back-and-forth between the fluid and solid form.

How much does a PVS impression cost?

The material cost of an average full-arch final impression is estimated to be just over $20. This can easily be approximated by adding up average PVS, retraction/hemostasis, mixing tips, adhesives, and tray component costs from supplier catalogs.

How long do silicone impressions last?

Her research proposed a maximum storage time of silicones for 2 weeks; however, the literature suggests that impressions can be reused weeks or months after the setting of the material [2,32,33].

Is impregum hydrophobic?

Polyether is hydrophilic by nature of its chemical makeup. From the time it is mixed, until it sets, moisture in the mouth should not interfere with achieving accurate, void-free impressions!
