ALGINATES:

Impression materials are an essential part of the inventory in a dental office. Dentists use various impression materials for different stages of treatment. It also depends on the type of dental treatment. A universally used impression material, to make preliminary impression of the dental arches is the irreversible hydrocolloid, Alginate. Alginate impression materials are widely used in dentistry. The word alginate is derived from term ‘Algin’, coined by a chemist during the end of the 19^th century. Alginate is a peculiar extract yielded by certain brown seaweed or algae. Alginates are elastic, irreversible hydrocolloid materials that form an inseparable part of indirect restorations in dentistry. They are simple, cost-effective and with command over the working of the material, the dentist gets the impression right the first time. Alginate has been the staple of most dental offices in the world. Alginate impression materials can be used to make preliminary impressions for provisional crown and bridge restorations, study models and impressions off the opposing dentition. They are also used extensively for making impressions to fabricate orthodontic models, sports mouth guards, bleaching trays and many more. Studies show that alginate can be used as a final impression material for indirect restorations, that have chamfer preparation margins.

What are the different types of dental alginate?

Based on the setting time alginate impression materials can be classified as:

• Type I     - Fast setting
• Type II    - Normal setting

What are the mixing times for alginate impression materials?

• Fast set alginates                - 45 seconds
• Normal set alginates           - 60 seconds

 

Care should be taken to not overmix or undermix the material as it may result in the following undesirable outcomes:

• Overmixing           - Reduction in final strength and working time
• Undermixing         - Inadequate wetting, lacking homogeneity and poor detail reproduction

Cast pouring with alginate impressions:

Casts should be poured using vacuum mixed stone and a vibrator. Thick mix of plaster or stone can entrap air bubbles. The tray should be placed with the teeth down. If turned upside down there would be a tendency for the water to rise to the highest points, causing faulty cusp tips on the model. Moreover, inverting the tray might cause the alginate to bend away from the tray if the excess material was not trimmed prior to pouring. The case must be removed immediately after it has reached an adequate set. If not, it might result in a “moth eaten” appearance on the cast

 

What is the composition of dental alginate?

• Potassium alginate (15%)                  - Thickening agent
• Calcium sulfate (16%)                        - Reacts with potassium alginate to form the gel
• Trisodium phosphate (2%)                - Slows down the reaction time for mixing
• Diatomaceous earth (60%)                - Filler
• Zinc oxide (4%)                                    - Adds bulk to the material
• Potassium titanium fluoride (3%)      - Improve setting and surface strength

 

Storage and disinfection of alginate impressions:

Alginate impressions, once set, undergo imbibition and syneresis in a normal clinical environment. This makes the time taken from the set of the material to pouring of the casts very critical. Following removal of the impression from the mouth, the impression should be washed with a water spray. Disinfection of the impression can be done according the practitioner’s choice. The impression must be dried until the shine just disappears. The impression is covered with a damp gauze and stored in a zip-lock cover until pouring of the cast. It is important to note that the elastic recovery of the alginate impression material is slow, and hence cast pouring must be delayed for 10 minutes.

If the disinfection guidelines are not adhered to then distortion can be a problem. Disinfection sprays must be used with caution with alginate impression materials as they might result in the formation of air bubbles. Immersion disinfectants can be used for the recommended period of time, and the quality of the impression may not be impaired.
