Preclinical results were presented recently at the EAO meeting for Straumann`s innovative hydrogel-based membrane, which confirmed the product`s efficacy and ease of handling. The first clinical trial was successfully completed in the third quarter, with each of the endpoints being met. On this basis, applications for regulatory clearance should be submitted in the current quarter. Straumann and Kuros Biosurgery, a spin-off from the Swiss Federal Institute, ETHZ and the University of Zurich, applied for a patent on this technology in
The perils of living in New York go beyond the grave. The directors of seven funeral homes have been stripped of their licenses and face jail after pleading guilty to their role in what one US official called “the crime of the century” – whenever they got hold of a suitable corpse, they would tip off a team of illegal body harvesters led by Michael Mastromarino, a former oral surgeon who had lost his dentist`s license. Operating out of a
Sweden`s Medical Product Agency (SMPA) has announced it will delay its final verdict on the safety of Nobel Biocare AB`s dental implant NobelDirect, which is alleged to cause bone-loss, until November. The agency cited a delay in the release of Nobel Biocare`s two-year follow-up study as being responsible. Two Swedish dentists in May 2005 alleged that the product is causing bone-loss, prompting investigations by the heathcare authority.
Bicon have developed a new surface process, NanoTite™. A high-energy ion beam source aims a beam of ions at the surface of a target treated with HA. These high-energy ions eject the HA from the target/substrate and create a molecular cloud whose molecules bond with the surface of the Bicon Ti 6Al-4V ELI implant. This Ion-Beam Assisted Deposition process, which provides increased integration with the implant surface, is known as High-Energy Sputter Deposition. Using an Ion-Beam Assisted Deposition process, the
Ulf Wikesjö of the Medical College of Georgia has demonstrated impressive osseous regeneration around dental implants coated with recombinant human Bone Morphogenic Protein (rhBMP-2). Dr. Wikesjö is researching wound-healing and tissue regeneration with a $1.4 million grant from Nobel Biocare. In laboratory tests, rhBMP-2 applied onto implants directs endogenous stem cells to become bone-forming cells. The result was a nearly complete regeneration of lost tissue. He hopes to start clinical trials in the summer of 2006.
Famous mafia boss John Gotti, Dr Leonard Linkow and blade implants – all part of the history of implantology. An amazing story reported by the NY Daily News in 2002. Enjoy: Around 1988, after losing several teeth, Gotti tired of dentures and had permanent implants surgically installed and his remaining teeth capped. He visited the E. 50th St. offices of Dr. Leonard Linkow, a frank-talking New Yorker with a shock of white hair. Linkow had been famous among dentists worldwide
IVS Solutions AG has released a 2-dimensional implant placement planner that uses panoromic and peri-apical xrays for the implantologist to design the type and position of the implant(s). The software then produces a surgical plan which lists the implants planned for placement as well as an image of the planned implant positioned on the xray.
BEGO Implant Systems GmbH & Co has designed a customizable healing abutment designed to shape the soft tissue. By customizing the PEEK blank at the chairside the emergence profile can be shaped, elliptical or even triangular, depending on the circumferential shape of the tooth that is to be replaced. It is made of a high-strength and completely biocompatible plastic abutment made of (implantable) polyether-ether-ketone (PEEK). This material is trimmed into the required shape with the handpiece at the chairside and
Brown University engineers have shown that both zinc and titanium oxide nanosurfaces can reduce the presence of bacteria. Discs with nanostructured surfaces had bumps that measured only .023 microns in diameter. Discs with microstructured surfaces had bumps that measured about 5 microns in diameter. Microstructured zinc oxide discs were host to 1,000 times more bacteria than the nanostructured zinc oxide discs. Similar, but less striking, results were duplicated on titanium oxide discs. The engineer`s hypothesis is that: `with the nanostructured
Ceraroot have designed five ziconium-based one-stage implants for use in different areas of the mouth. The anatomically designed implants incorporate the abutment into the implant for a very esthetic result. An interesting video is posted on Google Video showing the use of a Ceraroot implant in an immmediate placement procedure.

An expert panel advising the Swedish Medical Products Agency on the safety of the NobelDirect implant has responded to a recent Nobel Biocare rebuttal letter in a critical manner. The Merrill Lynch analyst suggests a NobelDirect withdrawal may be ahead.
Thommen Medical has redesigned their VECTOdrill™ twist drills in a high-strength, alumina-toughened zirconia (ATZ). The drills` ATZ ceramic ensures efficient and consistent cutting performance throughout the life of the twist drill. The pilot drill design features a high efficiency cutting tip which initiates the pilot hole without the need for a round bur and has the ability to cut laterally to correct osteotomy location. These are similar in design to the MIS ceramic drills reported on previously.
Straumann has received a US patent for a bioactive coating for their implants. Their modified sandblasted and acid-etched (SLA) surface is coated with an Arg–Gly–Asp (RGD)-peptide-modified polymer (PLL-g-PEG/PEG–RGD). According to a study by Danny Buser, RGD-coated implants demonstrated significantly higher percentages of bone-to-implant contact as compared with controls at 2 weeks. The hypothesized mechanism is that the attachment of RGD peptides directed towards integrin receptors on the PEGylated surface promotes adhesion of cells of mesenchymal origin e.g. osteoblasts to the
Temporary Orthodontic Micro Anchorage System
Meisinger`s Benex Control system is part of their `Bone Management` instrument collection. It uses a teflon coated tooth-borne ratchet system to extract the tooth root. This is a variation on the `easy-x-trac` system profiled earlier this year.

RoboDent`s navigation and implant placement planning software works with its Lapdoc system to give realtime visual feedback on the angle, depth and direction of implant placement. It uses 5mm titanium microspheres attached to the handpiece to track the position of the drill tip in realtime allowing the implantologist to see the depth and angle of implant placement.
A. Titan has introduced an innovative system for atraumatic extractions. This system uses a pin placed in the tooth to be extracted`s root canal and then uses a rachet to pull the tooth out of the alveolus, thereby avoiding the rotational forces usually placed on the alveolus by conventional extraction methods. By removing the tooth in an atraumatic fashion, immediate implant placement is more feasible.
Osseo Scientific has introduced an innovative autogenous bone chip collector. It features a collection cup with a bur inside the bone collection cup. As bur penetrates the bone the harvested bone chips are stored in the cup ready for immediate use. The whole assembly is autoclavable and fits a standard implant handpiece.
Stoma has introduced an innovative kit to allow for optimal implant positioning and spacing. The system consists of two sets of seating sleeves with increasing diameters, 5 fixation pins and 3 straight and angled bone spreading instruments. The seating sleeves are used to plan the optimal implant diameter for a particular surgical site. They are also useful for determing the proper interproximal spacing in areas where multiple adjacent implants are planned.
OTA`s new balloon sinus lifter allows for less traumatic hydraulic sinus lifts (internal and lateral approach) by reducing the risk of membrane tears. The micro-mini balloon inflates to 1.9mm with saline administered via a 5cc syringe. The gentle pressure on the membrane expands the sinus graft space gently without any sharp instruments.
Mectron`s piezon-electric surgery system can be used for osteotomies and osteoplasty in implantology. Additionally it can be used in periodontal, endodontic and surgical orthodontics.

This unit comes with an array of handpiece tips designed for an array of surgical procedures.
DenX`s innovative CT-image driven implant planning and placement system, `IGI`, was recently honoured with a Medical Design Excellence Award. IGI allows a virtual implant to be placed on the CT image with the assistance of advanced planning tools. During the surgical procedure, the clinician guides the implant to the precise location, angle and depth required according to the plan. Real-time localization feedback assisted by audio and visual media allows the clinician to monitor the success of the procedure and avoid
Straumann has filed a US patent application for a Peek/Titanium composite one-piece Implant. This implant design features an outer titanium shell (label 1 and 2) and an inner core made of PEEK (label 3 and 4). This designs claims the aesthetic advantage of the white-coloured PEEK at the collar and abutment with the proven osseointegration properties of titanium. This is an interesting design response to the number of zirconium collar (TBR Group) and all zirconium implant (Z-Systems) designs.
MIS has introduced a ceramic composite (Zirconium / Yttrium / Aluminium) drills in 2.0 mm, 2.1 mm and 2.8 mm diameter. They reportedly feature reduced vibration and smoother operation. One important property that Zirconium drills claim over stainless-steel drills is that they maintain their sharp edge for an extended period.
Thommen Medical has introduced their SPI MONO torque ratchet. It is manufactured from a solid billet of titanium. It has a torque range of 10Ncm to 35Ncm in 5 Ncm increments. The one-piece construction simplifies regular maintenance as there are no parts to disassemble for cleaning and no lubrication is required.
Straumann has filed a US patent application for a root-form implant with an asymmetrical shoulder. It appears similar to their current TE implant design, with the addition of a sloping shoulder configuration higher on the palatal side and lower on the facial side. This may be their design response to NobelBiocare`s Nobel Perfect implant originally patented by Dr. Wohrle.
Nobel Biocare has introduced an improvement to their Ti-Unite Surface. By placing micro grooves on the surface they claim to increase the implant stability by up to 30% thereby allowing for more rapid bone formation. This surface improvement takes a mechanical approach to increase Bone-to-Implant Contact as opposed to the chemical surface modification`s introduced by Astra (Osseospeed) and Straumann (SLAtive), their main competitors.
NSK has introduced several improved features to their implantology handpiece and motor system. The `Surgic XT Plus` features a fiber-optic handpiece to illuminate the osteotomy site and a torque calibration feature to ensure precise speed and torque during surgery.
Z-Systems has introduced a completely metal-free implant and set of surgical instruments for placement of these implants made from 95% Ziconium dioxide and 5% Yttrium tri-oxide. Zirconium is one of five metals shown to support osseointegration (the others are: Titanium, Niobium, Tantalum and Platinum). This new approach has been certified for use in Germany, but FDA clearance for use in the United States is planned. A few animal and human based studies suggest that the bone-to-implant contact percentages (a measure
Kavo has introduced an innovative implantology handpiece with a fiber-optic light. This is a part of their Intrasurg 300+ implant motor and handpiece set. It also boasts a torque measuring feature to aid in immediate placement and immediate load decision making.
B.T.I. has introduced a bone expander drill set. It uses a set of four wedge-shaped bone expanders to expand alveolar bone and condense bone in sites with low bone density. The rotary motion of either an implant handpiece or a torgue wrench is used to slowly expand the bone instead of using the more traditional osteotome/bone condenser/ridge spitter and surgical mallet combination.
T.B.R Group has introduced a unique ziconium collared implant. It features one-stage titanium implant with a zirconium trans-gingival emergence collar. They claim that the Zirconia enhances the fibroblast and osteoblast cell adhesion and proliferation compared to titanium, provides for lower bacterial colonization at the collar and shows evidence of creeping attachment of the gingiva to the zirconium collar.
Straumann has introduced an improvement in their SLA implant surface. SLActive is based on the scientifically proven SLA® surface topography, but exhibits a fundamentally improved surface chemistry. Due to its ideal conditioning, the chemically active and hydrophilic SLActive surface significantly promotes the osseointegration process. Animal studies demonstrate that their new surface allows for accelerated bone remodelling during the entire osseointegration process.
MIS Implant Technologies Ltd`s new compression kit improves the treatment procedures for sinus lifting and soft bone compression. A simple bone compression procedure enables better implantation and better implant primary stability. The compression kit can be operated either manually or with a contra angle, according to the surgeon`s choice.
