Significant Advances With Pentron’s Tempspan Materials
With Pentron Clinical’s TempSpan® line of provisional materials, “our thought process was to provide the clinician or dental assistant with all the tools needed to fabricate durable, highly esthetic provisional restorations—quickly and effectively,” says Jeremy Grondzik, Product Manager.
“We saw a few areas where we could improve on the products already on the market—most notably in the delivery system,” Grondzik explains. “Before TempSpan was released, most provisional materials required a unique dispenser gun that the clinician would have to purchase and store. We developed an automix material to utilize the standard 1:1 dispenser gun that all clinicians and dental assistants have access to.”
Pentron made other important advancements with TempSpan. “We found ways to improve the speed that these materials are used at. We wanted to make a material that was dual-cured, so that the clinician or the assistant had the option to light cure the restoration to shorten provisional procedure time. As an added benefit, when the material is light-cured, we witness an improvement in the transverse strength—about 60%. This contributes to provisional restorations that are very durable, very long lasting.”
Pentron Clinical’s comprehensive provisional line includes TempSpan Dual Cure Temporary Crown & Bridge Material, TempSpan Clear Matrix Material, TempSpan Glaze, TempSpan CMT Temporary Cement, and new TempSpan Transparent Temporary Cement. “Clear Matrix is a medium viscosity clear vinyl polysiloxane material dispensed from a cartridge,” Grondzik says. “Our TempSpan provisional glaze is virtually a liquid polish, which would be used either in addition to polishing or instead of polishing to help shorten procedure time. And lastly, we developed a noneugenol Temporary Cement formulated to help reduce sensitivity during the provisional phase.” These products work in tandem or can be used individually to create an efficient, convenient, highly effective process for the clinician.
Regarding the biocompatibility to gingival tissues and pulp, Grondzik says, “In general, TempSpan is the same resin technology that’s commonly found in our resin dental adhesives and cements, as well as the resin composites that are on the market from most dental manufacturers. Therefore, there’s really no difference as far as biocompatibility is concerned toward the gingival tissue or pulp, as long as the material is processed properly.”
The TempSpan Provisional System comes with a thorough instruction manual, featuring step-by-step photographs that cover a multitude of techniques and procedures. “In this manual, you have everything from how to take a pre-operative impression with our Clear Matrix material, to fabricating the provisional restoration, to finishing, polishing, and glazing the provisional,” Grondzik says. The manual is available on the Pentron Web site, along with technique tips, webinars, and CE courses.
Keeping an eye on the future, Grondzik expects to see increased use of nanotechnology and more semipermanent or long-term provisional restorations to complement implant placement procedures. As for Pentron, “We will continue to review, improve, and create products, working with our network of key opinion leaders to develop materials that make the provisional process quicker, easier, more efficient, and more cost effective for our customers.”
