Professor unveils data on new dental fillings that will repair tooth decay

The first data on dental fillings that can actively repair tooth decay was presented by Robert Hill, Chair of Physical Sciences at the Institute of Dentistry at Queen Mary University of London and co-founder and director of research at Biomin Technologies. Over 80 percent of the population in the U.K. has at least one filling, with seven being the average while eight million cavities are filled with amalgam each year. This data, indicating smart repair of tooth decay, prolonging the life of composite fillings and reducing the need for mercury based amalgams indicates a significant step forward in tooth restorative materials. Hill outlined how new bioactive glass composites are unique in their ability to release fluoride as well as the significant quantities of calcium and phosphate that are needed to form tooth mineral. Hill said that while current dental fillings include inert materials, the data on the new bioactive glass composite shows that it interacts positively with the body providing minerals that replace those lost to tooth decay. "Our scientists and dentists at Queen Mary University of London replaced the inert tooth filling materials with our new bioactive glass, explained Hill. "Not only did this bioactive glass composite remineralize the partially decayed teeth, but it also creates an alkaline environment that discourages the bacteria that caused the initial decay." Richard Whatley the CEO of Biomin Technologies who has recently licensed the technology from Queen Mary Innovations, noted that there is a huge pressure to eliminate mercury based amalgam fillings by 2020 which is outlined in a host of international agreements. "Using this type of bioactive glass composite to fill cavities eliminates the need to use mercury based amalgam by offering aesthetic white fillings which help heal the tooth," he said.

Ulrich Medical USA reports
product line extension

St. Louis-based Ulrich Medical USA Inc., a subsidiary of Ulm,Germany-based Ulrich Medical developing musculoskeletal implant technologies, reported the U.S. market release of Ucerv titanium spinal implants as an adjunct to its current Ucerv Peep Optima Interbody System which is an existing product used for anterior cervical discectomy and fusion (ACDF) surgical procedures. The Ucerv titanium implants have a roughened-surface design with a trapezoidal shape and are available in parallel or lordotic configurations of various heights in small, medium and large footprints. In addition, these implants feature optimal teeth patterns on the superior and inferior surfaces to limit migration.

Spineology unveils TLIF insertion options for posterior midline approach ACT MediaLIF

Minneapolis-based Spineology Inc., reported the availability of multiple transforaminal lumbar interbody fusion (TLIF) technologies as part of the Anatomy-Conserving Medial Lumbar Interbody Fusion (ACT MediaLIF) platform. These TLIF technologies allow for TLIF placement of interbody devices using a direct posterior, or ACT MediaLIF, approach. The ACT MediaLIF procedure combines Spineology's Medius Retractor, Rampart Interbody and Fortress Pedicular Fixation Systems to provide an anatomy-conserving approach to posterior lumbar surgery that can reduce incision length, dissection and retraction requirements compared to traditional open surgery.

Rotation Medical bioinductive implant
grows new tendinous tissue

Plymouth, Minn.-based Rotation Medical Inc., a company developing new technologies to treat rotator cuff disease, reported results of a biopsy study published online in Arthroscopy that it said supports the biocompatibility of the company's bioinductive implant and its ability to promote new connective tissue with the histological appearance of tendon. The Rotation Medical bioinductive implant is part of the company's rotator cuff system for rotator cuff repair and a new alternative to traditional surgical repair. "This is a breakthrough study, as it is the first to show that the Rotation Medical bioinductive implant promotes the rapid growth of tendon-like tissue in humans," said Steven Arnoczky, lead investigator of the study and director of the Laboratory for Comparative Orthopaedic Research at Michigan State University. "While clinical studies have demonstrated evidence of new tissue generation via imaging, the histologic character of this tissue could only be inferred. The unique opportunity to evaluate biopsies from implant recipients confirms the findings of the preclinical animal study, and demonstrates that the implant is biocompatible and promotes new connective tissue with the histological appearance of tendon over the surface of the native cuff tendon." The retrospective study included biopsies from seven patients undergoing a second arthroscopic procedure for issues unrelated to the implant at various time points (five weeks to six months) following arthroscopic rotator cuff repair with the Rotation Medical bioinductive implant. The biopsy specimens were examined histologically for host-tissue ingrowth, host-tissue maturation and host-implant biocompatibility. The study is titled, "Histologic evaluation of biopsy specimens obtained after rotator cuff repair augmented with a highly porous collagen implant."

Novabone secures approval of CE mark for collagen devices

Jacksonville, Fla.-Novabone Products, has received CE mark approval for Novatape and Novaplug, dental wound dressing products. Both products are 100 percent collagen based and designed for management of soft tissue oral wounds and sores, including dental sores, oral ulcers (non-infected or viral), periodontal surgical wounds, suture sites, burns, extraction sites, surgical and traumatic wounds.
