Kettenbach is known for developing high-quality crown and bridge technique materials, and Visalys Temp certainly is no exception. It has all the qualities dentists look for in a temporary material, giving them more confidence in provisionalization and leading to better outcomes for their patients.

Kettenbach asked the Catapult Group to provide an unbiased assessment of this material. The company wanted to prove it would meet, and even exceed, expectations. Catapult Key Opinion Leaders (KOLs) gladly put Visalys Temp to the test, and found it was a strong addition to the temporization category that outperforms its competitors.

A Closer Look at the Material
Before I get into our assessment, I want to talk a little about the material itself. Visalys Temp is a two-component, self-cured, multifunctional acrylic composite. It’s well suited for fabricating temporary crowns, partial crowns, veneers, inlays, onlays and bridges. It comes in shades A1 through A3.5, B1 and Bleach shade.

As you likely know, there are many materials in this category, but Visalys Temp stood out to us before we even used it. That’s because it’s one of the few temporary materials that has no Bisphenol-A or Bisphenol-A precursors in its chemistry. This was an attractive quality to many of our evaluators.

What We Looked For
When assessing this material, evaluators had to consider quite a few critical components, including:

  • Ease of use
  • Set and working time
  • Fit
  • Polishability/esthetics
  • Durability

With all that in mind, I, along with several other Catapult Group evaluators, began using Visalys Temp in our practices—and overall we were all pretty pleased with the results.

How Visalys Temp Faired in My Practice
In my office, I handled the material, as did my expanded duty dental assistants. Getting my team involved made it possible for us to discuss the material’s efficacy and applicability.

To start, we placed a single unit molar. The provisional was prepped for a full-contour zirconia crown. We made an addition silicone matrix before preparing the tooth, just like we do with most of our other provisionals. The material was easy to dispense, and its set time matched what was indicated in the directions for use (DFU), which was 1 minute and 20 seconds.

Once it was removed from the mouth and matrix, we gently wiped the provisional with alcohol to remove the oxygen inhibited layer. By then, 2 minutes had passed. At that point, the restoration was hard and ready for trimming. Per the DFU, we expected the material to complete final curing between 2 minutes and 20 seconds and 4 minutes.

Thanks to the material’s early hardness, handpiece trimming and polishing was very efficient. In fact, it was more efficient than with the material we typically use for provisionals. There were no voids in the temporary, which was cemented in place with Temp-Bond, and it fit beautifully.

We created 15 more units from Visalys Temp, both singles and multiples, and each time achieved very similar results. It did become clear, however, that setting times were shorter than what was shown in the DFU. We removed all temps from the mouth within 1 minute and began trimming all after removal and alcohol wiping (about 2 minutes).

The esthetic zone temporaries were very appealing and we never experienced any of the common problems associated with provisionals, including shade instability and fracture. Trimming and polishing also remained simple with every case.

Everyone in my office came to the same conclusion: Visalys Temp out-performed our current temporary material in just about every category.

The Catapult Evaluation
The Catapult KOLs were also rather impressed with this provisional material, with just about half of them rating Visalys Temp as better than the material they were currently using. In fact, 78 percent said they would replace their current product with Visalys Temp (assuming similar pricing), while 90 percent said they’d have no problem recommending this material to their colleagues. During the course of the evaluation, our KOLs placed more than 250 temporary restorations with Visalys Temp.

Evaluators looked at many different qualities, but the excellent fit at the margins, fewer voids, faster set time, hardness, ease of trimming, polishability and handling were among the features they liked best. They also agreed that being BPA-free gave Visalys Temp an advantage over other similar materials, and was just another reason for dentists to make the switch.

Suggestions for improvement
The evaluators gave this material high marks, and couldn’t come up with much in the way of suggestions for improvements. They did, however, recommend shortening the working/set times in the DFU to prevent new users from experiencing early set and locking undercuts. Catapult Group evaluators also said the company might want to consider incorporating a slightly smaller mixing tip because of excess waste.

The Conclusion
Kettenbach always has been committed to developing high-quality provisional materials, and Visalys Temp doesn’t disappoint. The superior material truly sets the company apart from the competition. The physical characteristics of this provisionalization system makes it a great option for both short- and long-term use.

Here’s what a few of the evaluators had to say about Visalys Temp:

  • “We liked the material. The color properties were good. The fit and trimming were excellent.”
  • “Very good material. The temps we made with it had no problems at all.”
  • “Excellent material. Had no failures.”
  • “Material performed well. Most critical feature of provisional material is fracture resistance, which this material seems to have!”

Clinical case: An Example of How Visalys Temp was used in a Clinical Situation
In this case, A 69-year-old male presented with a fractured mandibular first pre-molar (No. 21) (Fig. 1).The tooth was endodontically treated years before, but never properly restored. A core build-up and single unit e.max crown from Ivoclar Vivadent was planned with a Visalys Temp provisional restoration.

Composite was added to the fractured tooth to restore form for the addition silicone temporary matrix before preparation (Figs. 2-3).

The temporary crown was immediately removed from the matrix with a plastic instrument. It was then wiped gently with an alcohol wipe to remove the oxygen inhibited layer (Fig. 5).

Once preparation and impressioning were complete, Visalys Temp was used to fabricate a provisional crown. To ensure even flow of the two cartridge chambers, a small amount of the material was extruded before the new mixing tip was placed on the Visalys cartridge (Fig. 4).
The mixing tip was placed in on position. The material’s viscosity easily filled the unprepared matrix, and in less than 1 minute, the matrix was carried to the mouth and removed.

Shaping and polishing began at about the 2-minute mark (Fig. 6). By the 5-minute mark, the restoration was seated with a provisional non-eugenol cement.

Using a fine diamond and brownie point at low RPM, final occlusal adjustments and polishing were accomplished intraorally (Fig. 7).

Final Thoughts
Catapult KOLs loved the material’s handling characteristics and found it easy to work with, shape and polish. They agree Visalys Temp makes for a durable temporary restoration, and even though shades were limited during the evaluation, they were able to achieve outstanding results.
