Simplifying Temporaries
A single-dose premixed putty for easier use
Figure 1 | Temporization for endodontic access or indirect restorations other than full coverage crowns is part of every general practice. Traditionally, endodontic access has been sealed with ZOE-based materials, which require mixing of a two-part powder-liquid or the use of a zinc oxide-based premixed putty in a jar or tube. Premature setting of the material before the jar or tube is empty and the need for mixing are disadvantages of these products.
Tempit®, a premixed, single-dose, moisture-activated material, is an established product with a record of success. Tempit has a calcium sulfate and zinc oxide formulation that contains no eugenol. The compules fit into a composite syringe, allowing direct dispensing into the endodontic access opening. Setting time is approximately 5 minutes, but tamping with a wet cotton pellet will accelerate setting of the outer layer. This material expands slightly upon setting to better seal the pulp chamber. Ideally suited for short periods between appointments, Tempit has better wear than other premixed putty materials. Removal is easily accomplished with a bur.
If a longer period is anticipated between appointments, Tempit L/C is better suited for temporization. This light-curable material is dispensed in a single-dose compule. When light-cured, the material sets to a firm yet flexible consistency that can easily be removed with an instrument (plucked out). When used for sealing an endodontic access, remove the material by threading a large endodontic file into it and tugging it out. Tempit L/C is well suited for temporization of inlays/onlays while the restoration is fabricated at the lab or for endodontic teeth when less tooth structure is present to retain the temporary material. With its translucent color and soft texture, it also makes a good material to cover sharp orthodontic brackets and wires that irritate a patient’s lips and cheeks.
For those clinical situations when a longer term temporary is needed, or the patient is harder on the provisional restoration, Tempit Ultra-F, a hard setting light-curable material, is indicated. With less solubility than ZOE intermediate restorative materials, this non-eugenol containing material requires no etching or bonding and will last up to 1 year, resisting chewing wear. As it releases fluoride, Tempit Ultra-F is also recommended for use in deciduous teeth as an interim, tooth-colored restoration until the tooth is exfoliated.
In my practice, I find that the use of the right Tempit material provides improved restorative success.
Key Takeaways
- Direct to prep delivery
- Three unique materials, one for each need
- Easier, faster intraoral placement
