Temporary materials in dentistry
While the importance of temporary dental restorations is often underestimated, they fulfill many different functions which are crucial to the final treatment outcome. They provide interim protection to the underlying tooth structure, function and esthetics. In addition, the provisional restoration can help to condition the gingival tissues prior to making the final impression. If the soft tissue is healthy and well adapted, it will ease the impressioning and cementation procedure, with a positive impact on the treatment outcome including pink and white esthetics. Finally, yet importantly, within complex rehabilitations, the temporary is also used as a basis for the production of the final restoration, a “mock up” allowing for a therapeutic clinical test drive. In order to accomplish these tasks, the selected material should meet certain requirements in terms of marginal quality, mechanical strength, as well as mechanical and dimensional stability.
Available options and decision criteria for dental temporization
Four main material options for temporary dental restorations are available:
- Conventional materials based on methacrylate resins (e.g. Unifast III GC)
- Materials based on bis-acrylic/composite resins (e.g. 3M™ Protemp™ 4 Temporization Material)
- Pre-formed composite crowns (e.g. 3M™ Protemp™ Crown Temporization Material)
- Industrially fabricated PMMA disc (CAD/CAM production)
-

If the pre-existing anatomy of the tooth is available and the temporization period will be completed within one year (usual short-term and long-term temporization), a bis-acrylic resin is the recommended material option using a direct matrix. Bis acrylic materials have high mechanical strength and dimensional stability, superior esthetics, a lower setting temperature and polymerization shrinkage (for a precise fit) as well as better mixing quality as they may be delivered through an automix syringe. In comparison, conventional acrylics offer good fracture resistance and lower cost, but are generally inferior in strength as well as in dimensional stability and more difficult to use. Nowadays, CAD/CAM PMMA is the material of choice for indirect temporary restorations where the highest strength is needed.
If the pre-existing anatomy is not available at the beginning of treatment, there are different options to choose from. Usually, a matrix is produced on the basis of a wax-up and it is recommended to use bis-acrylic. One option available for a single-unit restoration in the posterior region is a pre-formed composite crown (3M™ Protemp™ Crown). This material is an excellent option for single unit crown and partial coverage restorations, where its high strength and moldability is advantageous when more conservative preparations have been made. Again, for any long-term temporization that takes longer than a year, the CAD/CAM procedure using PMMA discs is a viable option.
For dental cementation of the temporary restorations, a temporary cement (e.g. Temp-Bond™ NE, Kerr; 3M™ RelyX™ Temp NE Temporary Cement) is usually applied. Whenever the selected material for the definitive placement of the final restoration is resin cement, a temporary cement that does not contain eugenol is to be used. For long-term temporization, the use of permanent conventional or self-adhesive cements should be taken into consideration.

Clinical procedure: Direct fabrication of temporary materials
The production of temporaries with bis-acrylic resin – e.g. 3M™ Protemp™ 4 Temporization Material – is simple, easy and predictable. In this case, a preliminary impression is used as a matrix, and the provisional restoration is ready within a few minutes
Otherwise, a matrix can be produced in the laboratory based on a wax-up. When using Protemp 4 material, finishing and polishing is not necessary on the buccal or labial surfaces other than to simply wipe the outer surface with alcohol to remove its thin oxygen-inhibition layer. Shaping and occlusal adjustments precede as normal. The following clinical examples reveal how the material may be used to meet specific demands in different clinical situations. The last example shows an alternative temporization option for single teeth – the placement of a self-supporting, malleable, light-curable composite crown.
Case 1: Composite resin for temporary crowns
Substrate: Tooth Indication: Crown Number of restorations: 1-3 Temporization period: Short term
Recommendation: Bis-acrylic / composite resin
-
- Preliminary dental impression taken with a handmix putty as an alternative to 3M™ Imprint™ 4 Preliminary prior to tooth preparation.
-
- Use of 3M™ Astringent Retraction Paste for hemostasis prior to repositioning of the dental impression filled with temporization material in the mouth.
Tips
- Use of 3M™ Astringent Retraction Paste for hemostasis prior to repositioning of the dental impression filled with temporization material in the mouth.
-
- Dispensing of the bis-acrylic resin (3M™ Protemp™ 4 Temporization Material), which offers a 40-second working time, into the preliminary dental impression.
Tips
- Dispensing of the bis-acrylic resin (3M™ Protemp™ 4 Temporization Material), which offers a 40-second working time, into the preliminary dental impression.
-
- Temporary removed from the dental impression after final setting. Removal from the mouth is possible after 1:40 to 2:50 minutes from the onset of mixing, while the material should be left in the impression for 5:00 minutes after start of mixing before it is removed from the matrix.

Tips
The use of retraction cords and / or pastes in this treatment phase will contribute to an enhanced marginal quality of the temporary restoration, which, in turn, will provide favorable soft tissue conditions during impression and cementation.
Syringe around the margins after matrix is filled for optimal marginal imprint.
Intra-orally remove excess from neighboring undercuts whilst setting (wait until clean cuts can be made).
Case 2: Composite resin for temporary bridge
Substrate: Tooth Indication: Bridge Number of restorations: 4 or more Temporization period: Long term
Recommendation: Bis-acrylic / composite resin
-
- Situation after tooth preparation.
-
- Impression of the prepared teeth used for the production of a model and a wax-up in the laboratory.
-
- Dispensing of 3M™ Protemp™ 4 Temporization Material into the matrix produced in the laboratory on the basis of the waxup. Thanks to a high dimensional stability of the material, it is also very well suited for multi-unit temporaries.

Conclusion of temporary materials in dentistry
The temporization phase plays an important role within the indirect restorative workflow. Bis-acrylic resins have advantages in their strength and esthetics, which make them versatile for most direct temporization procedures. When single-unit posterior restorations are produced, the pre-formed composite crown may also be a suitable option for temporization. In order to produce a temporary with a precise marginal fit that supports the healing and correct contouring of the soft tissues, clinicians should have a dry and well-retracted field. It is therefore recommended to use mechanical and chemical tissue management techniques by means of retraction cords, astringents and / or pastes for effective tissue displacement and hemostasis (margin position dependent).
As in the other procedure steps, standardization is a decisive measure. It brings routine into the selected procedures and helps eliminate potential sources of error.
