The quality of the dental impression is determined by several aspects, such as the size of the used tray, the clinician's expertise, the quality of the impression material, and how well it is mixed.
To ensure the procedure's success, the clinician must ensure that the material is evenly mixed. However, different materials have different mixing times. Therefore, the clinician must mix it fast to pour it on the tray.
Although mixing the material can be done manually, a dental vacuum mixer can make the process easier and faster.
A dental vacuum mixer is a specialized machine that mixes impression materials. This machine makes the process automatic by just pressing a button.
The dental vacuum mixer consists of a case that has a spinning blade hanging from the top. A clear plastic cup is then placed on the machine. Furthermore, the spinning blades end up inside the cup after set up.
As expected, the practitioner must place the impression material inside the cup.
What makes a dental vacuum mixer special is the vacuum pump effect. When active, the machine creates a vacuum pump while mixing the material. This enhances the mixing process, making the mix more even and reducing the air bubbles trapped inside the putty mix.
Furthermore, some dental vacuum mixers also have a vibration feature to enhance the result.
