To cement or to screw – that is the question. Not anymore, startup RODO Medical has added a new option. Reversible retention using a shape memory metal dental retention system which uses one or more compression plates made from various shape memory materials, e.g., nickel-titanium alloys such as Nitinol. By applying energy via heat or electrical energy, the memory metal elements change shape. To remove a crown, energy is applied via a wand and the memory metal retentive element shape
In a deal worth $13.35, which has been approved by both companies’ boards, positions Zimmer, based in Warsaw since 1927, to become the second largest company by revenue in the $45 billion global market for artificial knees, hips and other orthopedic and bone-mending implants. The acquisition price, which includes the assumption of debt, consists of $10.35 billion in cash and $3 billion in Zimmer shares. The Zimmer-Biomet merger is the largest in the medical-devices industry since Johnson & Johnson purchased
Two recent recalls by the US Food and Drug Admininstration (FDA) of Zimmer’s Trabecular Metal Technology, one in dental implants and the other in shoulder implants raise concern. In the case of the recall of the Trabecular Metal dental implant: The Zimmer Dental voluntary device recall resulted from an investigation into the February 2012 complaint involving an apical tip of a 4.1mm D Trabecular Metal Implant which separated from the implant assembly during surgery on a patient with a dense
The FDA (US Food and Drug Agency) is proposing to reclassifying blade implants in a possible come-back for this type of implant. In a FDA press release they are proposing to change the classification from Class III devices to Class II devices because the benefits of blade-form implants “outweigh the risks enough to justify reclassifying the implants from class III, requiring premarket approval, to class II, requiring premarket notification with special controls,”. Class II medical devices are of “medium risk,”
An Massachusetts Institute of Technology (MIT) research team that may have found a way to make bone implants less likely to fail using a high-tech adhesive that more securely bonds implants to bone by promoting cell growth between natural and artificial body parts. In a study published in the June 26 online edition of Science Translational Medicine, the MIT team and its collaborators from several other institutions reported that the implant adhesive — a multilayered coating of ceramic and nanolayers
Blue Sky Bio has released their BIO|Cut drill that features a unique drill topography to cut bone very efficiently without the need for sequential size drills. Only the final implant specific drill is needed to shape the osteotomy before implant placement. This design is particularly useful in guided surgery and allows very accurate guided osteotomies to be made without the need for key guides and sequential drill sizes which can introduce and compound inaccurate positioning. This system allows you to
Tantalum, element #73 on the periodic table has found its way into dental implants thanks to mega dental implant manufacturer, Zimmer. They have tranferred it from use in hip implants to dental implants. The trabecular metal material structure and stiffness similar to trabecular bone and is fabricated by coating a vitreous carbon skeleton with tantalum through a proprietary chemical vapor deposition coating process. The tantalum exhibits a crystallographic growth on the vitreous carbon surface of the interconnecting struts that form
Italian Manufacturer Sweden and Martina’s Magnetic Mallet is an innovative tool for Dental Surgery and Implantology. The magnetic mallet’s main application is in the maxillary sinus for use in bone compaction protocols and vertical and horizontal compaction. It is also useful in cases that call for the use of a surgical hammer. The device exploits electromagnetic impact, which allows an impact force of high intensity and short duration to produce plastic deformation of bone, without propagating the force throughout the
BioImplant is an Austrian dental implant company with a radical new solution to immediate dental implant placement. The patient`s extracted tooth is laser scanned and modified in CAD software, then machined out of zirconium and implanted in the still healing socket for incredibly natural looking results.
The 6th International Congress of the CAI Academy will be held in Verona, Italy from October 28 to 19, 2011. Computer aided implant surgery has reached peak levels of acceptance giving proof of the clinical efficacy of computerized procedures. The Congress will focus on the need of defining the state of the art in research and clinical application. Two main areas will be analyzed: topics of current research and current clinical application. Amongst the speaker are: Dr. Scott Ganz, Dr.
