Multiple New Product Launches Scheduled for Chicago Dental Society Mid-Winter Meeting

Among the products that can be seen at the meeting, a new electric motor controller for performing endodontic (root canals) procedures will be shown by SybronEndo, a division of Sybron Dental Specialties, a long-time customer of Pro-Dex. The new motor controller contains proprietary technology that allows the device to communicate directly with SybronEndo's Elements(TM) Diagnostic Unit, permitting the doctor to simultaneously shape the root canal and measure the progress of that shaping procedure.

Also being introduced at the meeting is the next generation of the IntraFlow(TM) Anesthesia Delivery System from IntraVantage, Inc. The new IntraFlow(TM) HTP is a one-step intraosseous system, that instantly delivers anesthesia to a targeted tooth. This eliminates facial numbness and patient discomfort, during and after the dental procedure, as is normally associated with delivering local anesthesia. Given the success of the original IntraFlow(TM) released in 2003, Pro-Dex in conjunction with IntraVantage's design team, developed a more compact and ergonomically pleasing handpiece as the central component of the System.

Finally, a duo of new prophy handpieces manufactured by Pro-Dex will be available from Sullivan-Schein Dental, a division of Henry Schein Inc., under the Henry Schein brand name of Acclean(R). The two handpieces are specially designed for use by dental hygienists in providing prophylactic teeth cleaning. Ergonomically designed and constructed of aluminum and stainless steel, the handpieces provide a light feel, while delivering superior performance and reliability.

Total first year sales of these three new products is projected to be approximately $2,500,000. Pro-Dex has already begun delivery of two of the products and is scheduled to begin shipments of the third by the end of February. Pro-Dex will also be showing several recent additions to its Micro Motors line of branded handpieces, products that are sold by major North American dental dealers. Pro-Dex will be exhibiting in booth #109 at the McCormick Place Convention Center in Chicago.
