Best Impression Materials for Your Practice

The role of the impression material
An accurate impression is the first and most important step of prosthetic work. Models produced from a low-quality impression material can cause errors at every subsequent stage.
For this reason, choosing an impression material should be a strategic decision that matches the situations your clinic handles.
The advantages of VPS materials
Vinyl polysiloxane (VPS) materials offer high precision, dimensional stability, and the ability to be stored long-term. These qualities make them an ideal choice for crown and bridge work.
The range of viscosity options within GC Dental's VPS line lets dentists choose the material that fits the clinical situation.
When alginate is preferable
Alginate materials are widely used for diagnostic models and orthodontic purposes thanks to their speed and cost-effectiveness. However, this material's dimensional stability is lower than that of VPS.
If the model will not be poured immediately, more stable alternatives to alginate should be considered.
Recommendations for the right choice
Material selection should factor in the clinical scenario, workflow speed, and budget. The Meridian team can help you choose the most suitable combination of impression materials.
