Impression Materials
This impression material is commonly used for preliminary impressions because it is inexpensive and easy to mix
Alginate
This must be controlled when mixing alginate because it affects working and setting times
Water temperature
Dental model/cast
This cement will "cobweb" when the working time has expired
Polycarboxylate
This medical condition increases a patient’s risk of developing oral thrush due to changes in the body’s ability to fight infection.
Diabetes mellitus
In this state, alginate impression material is liquid before it sets into a gel.
Sol state
When taking alginate impressions, this arch should typically be taken first
Mandibular arch
Before trimming a dry dental model, it should be soaked in water for this amount of time
5 minutes
When testing zinc phosphate luting consistency, the cement should follow the spatula approximately this distance before breaking.
1 inch
This usually occurs in relation to the eruption of the third molars
Pericoronitis
Both alginate and agar-agar impression materials are derived from this natural source.
Seaweed
When removing an alginate impression from the patient’s mouth, the tray should be removed from the arch using this motion to help prevent distortion.
Quick snap
This device duplicates the relationship of the jaws to the temporomandibular joint
An articulator
This material, often used as a temporary restoration, may last up to 1 year once placed in the patient’s mouth.
Intermediate restorative material (IRM)
After a patient severely bites their lip and the bleeding has stopped, this should be applied to help reduce swelling.
Cold compress
This type of impression material softens when heated and hardens when cooled
Thermoplastic
This should be placed around the borders of a custom tray to create a proper seal
This device records the relationship of the maxillary arch to the patients skull
Facebow
This cement has a sedative effect on the dental pulp
Zinc oxide-eugenol
When oral trauma pushes a patient’s incisor inward toward the tongue, this type of dental injury has occurred.
Lateral luxation
This process occurs when an alginate impression loses water, causing shrinkage and distoration
Syneresis
This ration must be followed carefully when mixing alginate to ensure proper consistency
Water-to-powder ratio
This procedure involves removing excess stone and shaping the base of a dental model
Model trimming
This cement requires the tooth to be properly prepared and protected with liners/varnishes because its liquid form is acidic
Zinc phosphate
This oral lesion is generally caused by chronic periodontal disease and involves an infection of the periodontal tissues.
Periodontal abscess
