The advantages of using impression compound include reusability, biocompatibility and long shelf life. Since they are thermoplastic materials no chemical reaction takes place during setting. They are made up of resins, filler particles and lubricants. The sticks are usually used in border moulding, to record the functional depth and width of the sulci, before making the final wash impression.

The impression compound cakes are used in making full mouth impressions. They are thermoplastic materials, available in the form of cakes or sticks. Impression compounds are thermally setting, reversible impression materials. Light body elastomeric impression materials are used in conjunction with putty materials while making the impression, to record the finer details as they have better flow properties. Some of the frequently used putty materials include Novabone putty and Aquasil putty. Silicones are of two types Addition silicone and Condensation silicone, classified based on the type of polymerization reaction that takes place during the setting process.Įlastomers are available in different consistencies ranging from light body to putty like consistency. The types of elastomeric impression materials are:

Modifications in alginates include dust free alginates, siliconized alginates and alginates containing disinfectants.Įlastomers also known as rubber base impression materials are a group of rubber like polymers have high accuracy in impression making. The types of alginate include fast set (type 1) and normal set (type 2).Ĭhromatic alginates change color during the mixing and setting phases to help the dentist keep track of the process. Alginates are used to make preliminary impressions for dentulous and edentulous patients. It is an irreversible elastic hydrocolloid which is a mucous extract yielded from some brown sea weeds.

On the basis of rigidity, they might be categorized as rigid, such as impression plaster and impression compound, and elastic such as alginate and elastomeric impression materials.Īlginate is a widely used dental impression material. Thermally setting materials are reversible while the chemically setting ones are irreversible. Based on the mode of setting, they are classified as thermal setting and chemical setting. The impression materials used in dentistry can be classified under various heads. Hence this study assesses the awareness among the UG dental students about the advantages and disadvantages of organically derived impression material, it was clear that 88.9% of them are aware of organic impression materials.What are the different types of impression materials? After receiving the statistical results with the help of SPSS software.

The resulting data was analysed using IBM SPSS statistics software. To create awareness about the organically derived impression materials among UG Dental students a cross sectional questionnaire was formatted and distributed to the UG Dental students of various colleges.

The agar and alginate are two types of hydrocolloids used in dental impressions. It isn't precise enough for the fabrication of the fixed partial dentures which are used for partial impressions of the structure. Compared with other impression materials, it has moderate ability to reproduce detail and costs relatively little. It has a low wetting angle so it can easily capture impressions of the full arch. Hydrocolloids are of a high hydrophilic nature that enables this material to capture accurate impressions in the presence of some saliva or blood. The quality of these final restorations is highly dependent on the materials and techniques used for making the impression. Intraoral structures are recorded using impression materials for definitive restoration fabrications. Awareness Of Hydrocolloid Impression Materials
