Increased Tear Strength, Quick Setting Time Key Attributes of New Dynax® Impression Materials
As a seasoned clinician who has long been involved in sports dentistry, Ray Padilla, DDS, has performed his fair share of restorative procedures. Aside from owning a practice in Los Angeles, where he specializes in general and cosmetic dentistry, he is also the team dentist for UCLA Athletics, the Los Angeles Lakers, and the Los Angeles Galaxy. Not surprisingly, he has expertise in cosmetic trauma treatment and injury prevention. Having restored many sports-related oral injuries, Padilla relies heavily on high-quality impressioning materials and has been an avid user of EXACTA Dental Direct products for the past 25 years.
"I absolutely love their product line," Padilla states enthusiastically, specifically citing the company's vinyl polysiloxane materials. After many years of attaining successful results with EXACTA's FRESH Bold impression materials, he was eager to try the company's new Dynax® impression materials. Upon using Dynax, Padilla noticed increased tear strength, particularly in deep, thin sulcus areas. "Additionally, the intraoral temperature works to set this material faster," he observes.
He attributes these characteristics to the advanced technology behind the fabrication of the new material. According to the manufacturer, the Dynax silicones guarantee both precision and ease of use thanks in part to high hydrophilic and superior mechanical properties and an innovative "snap effect" that enables long processing time but a short time in the patient's mouth. The company says the entire impression procedure requires less than 3 minutes.
The Dynax line of impression materials from EXACTA includes Dynax mono, an "all-around" material for frequent indications; Dynax putty, an easily kneadable material well-suited for complex impressions; Dynax heavy body, a tray-type silicone that is highly thixotropic; Dynax light, which is thin-flowing for excellent detail precision; and Dynax clear, which enables easy checking of details during impression taking. All the Dynax silicones have scannable surfaces, allowing for use in conjunction with digital CAD/CAM technology.
While Padilla does not personally scan his own impressions, he often receives crowns from the lab that were produced from digitally scanned impressions. "The results of these crowns from the lab, with regard to fit and occlusion, are excellent, regardless of whether the impressions were scanned or poured in a traditional die stone," he attests. He says he rarely, if ever, needs to adjust the crowns.
When taking impressions, Padilla chooses the EXACTA triple trays, which come in full-arch, quadrant, and anterior options. He explains that after preparing the teeth and obtaining hemostasis with a gingival cord, he injects the Dynax heavy body on both sides of the triple tray. Then, under a dry, isolated field, he injects the Dynax light body into the sulcus of the prepared teeth, and surrounds the entire tooth in the light-body material. He then inserts and seats the heavy-body triple tray over the prepared teeth and instructs the patient to bite down; this establishes the bite and registration. Padilla lets the impression set for 4 to 5 minutes before removing it, then checks the margins and washes and dries the impression.
"I have no desire to use any other impression materials," he asserts. "I have experienced only fantastic results with EXACTA products"-which must be reassuring to him whenever a famous Laker comes into his office.
