Fast Setting Dental Impression Putty

Product Information

When the clinical procedure is limited to 1 or 2 units, the clinician may choose a dual-arch tray. A metal tray would be preferred over a plastic tray because of its rigidity and resultant dimensional stability. A tray material that is very inflexible should be used for its rigidity and ability to support gypsum when the model is poured. Silicones are the most dimensionally stable of all the materials and will keep their shape even if left for long periods. However, silicones work best in a dry environment and may not be ideal if there is a lot of saliva. Alginate is flexible and flows well. This allows the impression material to record fine surface detail. However, alginate does have poor dimensional stability and will distort if left to dry or left in water for too long. - Dr May Ali Two-stage un-spaced impression – putty impression is recorded first and after it has set it is relined with a thin layer of wash material. The mechanics of removing the impression involves separation at the impression/tissue interface and stretching of the impression. The first step is to break the physical adhesion between the tissue and the impression; therefore, an impression material, such as polyether, that wets the tissue well will require extra effort to break the seal for the removal. The second step stretches the impression enough to pass under the height of contour of the hard tissue to remove the impression; therefore, using a material of higher rigidity will require a greater force to stretch the impression to facilitate removal. Polysulfide has the lowest viscosity and ranks as one of the least stiff of the elastomeric impression materials of a similar consistency. This flexibility allows the set material to be easily removed from undercut areas and from the mouth with a minimum of stress.

Which of the seven criteria that ensure accurate impression making are related to the time the impression material is in the mouth? Which one is related primarily to the properties of a set impression? Limitations of this technique will be, restorations might require two appointments for patient and training in placing both mylar strip and index together in initial stages of usage. Also this technique will necessitate the practice of four handed dentistry, as operator will require to manipulate and place both mylar strip and putty index together at same instance. Case Diagnosis Newer classification for anterior proximoincisal preparation Some clinicians suggest preparations require a taper of between 2° and 6°. However, these numbers are not achievable in clinical practice. Enough powder has been incorporated for a base consistency when the mix “flakes” from the spatula when pressing on the cement. The data was collected from research studies retrieved from Google Scholar, Scopus, and PubMed using MeSH terms of keywords “vinyl polyether siloxane AND Disinfection” or (Vinyl polyether siloxane OR polyvinyl siloxane ether OR PVES) AND (disinfectant OR disinfection)” without any restriction to publication date. The PRISMA (Preferred Reporting Items for Systemic Review and Meta-Analysis) directions were observed during the data collection, screening of studies, and meta-analysis. The primary data were retrieved, and batch exported from databases using Harzing’s Publish or Perish software; primary analysis was performed in Microsoft Excel, while statistical analysis for effect size, two-tailed p-values, and heterogeneity among studies was performed using Meta Essentials. The effect size was calculated using Hedge’s g values at the 95% confidence level using the random-effects model. Heterogeneity among studies was measured using the Cochrane Q and I2.

There is no single procedure that a dentist can do, or any single procedure that a lab can do for the dentist, that will improve the final result of indirect restorations more than improving the quality of the impression. The impression is the basic starting point for all laboratory procedures, as well as the basis for quality and cost-effective dentistry for the clinician. A colleague recently pointed out that it is appropriate to change terminology from gingival retraction to the more correct sulcus expansion. Gingival retraction, which may have been a more viable term in years past when a patient’s tissue health might have been less than ideal, is no longer descriptive of the procedure that is actually performed. When a patient has good gingival health—and there should be no reason to begin an indirect restoration until that has been achieved—the procedure that is accomplished is a temporary expansion of the sulcus to permit access for final preparation of the margin and then taking the impression. Removing the cords after completing the impression then permits the tissue to return to its normal biological position without a change in the occlusal-apical height of the tissue. Changing the terminology helps the dentist, chairside assistant, and patient more accurately visualize and then achieve the ideal result. This guide will provide information about digital impressions and scanning within dentistry, including their roles, comparisons between new and traditional techniques and the benefits they offer to dentists and dental patients. In all cases it is imperative to be able to see the preparation for final margination, and then take the impression. The dual-cord technique accomplishes both, and when done properly in the preparation sequence can lead to minimal hemorrhage or gingival trauma.

Dental impressions are used to create models, or casts, of your mouth. These models show your dentist how your dental arches fit together, as well as the size and relationship of your teeth and gums. Dental impressions are used for a wide range of dental restorations and oral appliances, including: There are primarily two material classes that are widely accepted for precision impressions: Polyethers and A-type (addition-cured) silicones (VPS). Due to their low cost, C-type silicones (condensation-cured) are also still being used in some dental practices. However, their material-inherent high polymerization shrinkage leads to an inferior dimensional accuracy of the impression and therefore their use is not recommended for precision work.

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 Another study evaluated the effect of the viscosity of the impression materials in plastic and metal dual-arch trays.2 There were statistically significant differences noted in the accuracy of the dies. Rigid materials in metal trays were the most accurate, while monophase materials in plastic trays produced dies that were dramatically shorter.

Traditionally, creating an impression involves using dental putty to form a mould of the mouth; not only is this messy and potentially inaccurate; it may also be very uncomfortable and unpleasant for the patient, especially if they feel anxious or they have a very sensitive gag reflex. When a dentist creates a mould in this way, they insert the putty into the mouth and then shape it, so that it covers the teeth and gums; when the putty sets, a model of the mouth is formed. These models are then sent away to a laboratory where dental technicians will use them as a basis for a new restoration, such as a crown or bridge, or a gum shield for sport, for example. Some patients may be sensitive to materials containing eugenol, which can cause a burning sensation. It has a limited working time based on the temperature of the water used and it is available in both standard and fast-setting varieties.

Kotsakis G, Chrepa V., JIACD Apr 2012; 4(2): 41-47. The putty/wash techniques fall into 2 basic categories: (1) a single-step procedure where the putty is loaded into the tray and inserted immediately after syringing a wash material around the prepared tooth or teeth, or (2) a 2-step procedure where the putty is used to take an impression before starting the preparation, allowed to set, and removed from the mouth. After tooth preparation is complete, the tooth has a wash material syringed over it, and the initial tray and putty impression are reinserted over the wash. Variations of this include routing out part of the putty impression around the prepared tooth to produce space for the wash, and relining the entire impression with wash material. Dentistry is evolving and advancing at a rapid pace and traditional methods are being replaced by new and innovative technology. The introduction of new technology often improves accuracy and efficacy of treatment, reduces time in the dental chair, increases cost-effectiveness and makes the process less stressful and time-consuming for both the patient and the dentist.
