Alginate is the most widely used of all the impression materials its is a hydrocolloid material made from seaweed. A hydrocolloid material is a gelatinous substance dispersed in water. It is described as being irreversible as it cannot return to a solution once set. Alginate also contains; Prepare teeth with a new, or nearly new bur. This will make the cutting more efficient, reduce appointment times, and reduce the heat you transmit to the pulp, reducing the risk of pulpal complications. Good retraction and good vision

When alginate is in its original state it comes in a form of powder in a variety of colours. Some alginates also have colour changing properties that help with mixing, loading and setting times. This is particularly helpful with less confident team members that take dental impressions and also nervous patient or those with gag reflexes. When alginate is mixed with water it forms a paste and then becomes a solid, elastic mass which gives us a negative reproduction. This can then be used to create a positive reproduction. An alternative approach is to inject the wash material around the preparation and then immediately seat the tray with freshly mixed putty over the wash material. However, this approach risks displacing too much wash material by the putty, so that a critical area of the preparation is reproduced in the putty without the required detail. Occlusal stops should be used in the tray to avoid having the teeth penetrate through the wash or syringe material when the plastic putty mass is being seated. Soh G, Chong Y H .

Nov-Dec 2015; 35(6):e90-6.Many dental offices now have the ability to take digital dental impressions. During this procedure, your healthcare provider uses a digital handheld wand to capture thousands of pictures of your teeth and gums. As your healthcare provider passes the wand over your teeth, images of your mouth will come up on a computer screen. Next, the computer software will stitch the images together, creating a digital, 3D representation of your dental arches. There’s no need for putty when taking digital dental impressions.

Material and methods: Ninety samples were obtained from polyether ImpregumTM PentaTM (3M ESPETM, Seefeld, Germany) and 90 of addition silicone ImprintTM 4 PentaTM Putty (3M ESPETM, Seefeld, Germany) according to ISO 4823:2000. The samples of each material were split to form three groups with 30 samples each: a control group, a hypochlorite group (disinfection) and an autoclave group (sterilization). Samples were stored in the Portuguese Institute for Quality for six months at 23 °C. Samples were measured by laser interferometry, according to the Michelson technique before calculating dimensional stability according ISO 4823:2000. A statistical analysis via a three-way mixed ANOVA was performed.Certain materials require more reduction than others. This is due to physical or optical properties. As discussed in Chapter 7, Dental Cements, glass ionomer cements are high in strength and low in solubility. Compared to other cements, they are also relatively kind to the pulp. They chemically bond to tooth structure, and they release fluoride ions into enamel and dentin, which is believed to reduce recurrent decay. It is for these reasons that this cement has become so popular. C.Dispensing Systems Profeta AC, Prucher GM. Bioactive-glass in periodontal surgery and implant dentistry.

To support my research on impression materials I asked two dentists their opinions on the different impression materials: Your healthcare provider will then electronically deliver your photo files to a dental lab. There, a technician will begin working on your case. How long does a dental impression take? The differences between impression materials, as outlined above, are the materials themselves and the purpose they are used for. Each of the materials has advantages and disadvantages, but they are each used for a different purpose and are effective and commonly used products in dentistry today.

The base paste, is a polysulfide polymer that contains a multifunctional mercaptan (-SH) called a polysulfide polymer, a suitable filler (such as lithopone or titanium dioxide) to provide the required strength, a plasticizer (such as dibutyl phthalate) to confer the appropriate viscosity to the paste, and a small quantity of sulfur, approximately 0.5%, as an accelerator. The catalyst (or accelerator) paste contains lead dioxide, filler, and plasticizer as in the base paste, and oleic or stearic acid as a retarder to control the rate of the setting reaction. Lead dioxide is the component that gives polysulfide impression material its characteristic brown color. The terms catalyst and accelerator used here and with other impression materials are actually misnomers. Reactor is a more appropriate term for the reactions associated with polysulfide and other types of impression materials.

If necessary, your dentist can place a temporary restoration while you’re waiting on your case to be completed. This is common practice for people who are missing a front tooth. That way, you won’t have a gap in your smile in the meantime. Are there risks associated with dental impressions?

American National Standards Institute and American Dental Association. ANSI/ADA Specification No. 19: Dental Elastomeric Impression Materials. Chicago, Ill: American Dental Association, Council on Scientific Affairs; 2004. Dentists can use a number of different techniques that employ a variety of different materials and viscosities to take impressions. Traditionally, a heavy-body tray material is utilized with a lighter body wash material that is syringed around the tooth just before the tray is seated. Since the 1980s, with the introduction of vinyl putties, several putty/wash techniques have been advocated. Various innovations of these techniques have emerged, further confusing the clinician. Although it is possible to get many different techniques to work, the final choice as to technique should center on which is least problematic and most likely to produce consistent results. Now you only need to prepare the area shown in green on Figure 12 to finish the preparation. Sharp burs
