The 3M Protemp 4 temporary crown kit is made of bis-acryl resin, which is used to make temporary crowns and bridges. It's made for certified dentists who need consistent handling and a good fit at the edges. The material sets quickly with little heat, which makes the placement process much more comfortable for the patient.
Before placing temporary crowns, dentists typically use precision impression material to capture accurate tooth structure and ensure proper fit during restoration.
This temporary crown kit comes with mixing tips, base paste, and catalyst paste. Upon mixing, it chemically polymerizes fast. This temporary crown resin is stable once it sets, which helps keep the fit needed to preserve prepared teeth. The material can be used for both direct and indirect methods. This temporary crown filler protects the tooth and is safe for use in restorative therapy.
Product Uses
- Temporary crowns for teeth in the front and back
- Temporary bridges with more than one unit
- Temporary covering after preparing the tooth

How to Use
- Make sure the tooth is clean and dry. Use vaseline to protect your gums.
- Put the same amount of base and catalyst paste on a mixing pad or into the tip that came with it.
- For 30 to 45 seconds, mix in a figure-eight motion until the color is even.
- Choose a crown shape that matches the tooth that has been prepared. Before filling, make changes.
- Fill the crown form with a mix of materials, making sure there are no air bubbles.
- With little pressure, put the filled form on the prepared tooth for one to three minutes. Allow to set as per manufacturer guidelines.
- Take off the crown form and see if it fits. Use the right burs to cut out extra material.
- Check the occlusal contacts and make adjustments by selectively grinding.
- Use polishing agents to make the repair shine.
