Merrill Lynch and UBS have released stock research reports regarding Nobel Biocare`s NobelDirect implant design. Several recent studies suggest more than 3mm of bone loss in 14-55% of patients. 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.
Karl Schumacher`s Proximator extraction kit consists of 7 periotome-like elevators designed to fit different aspects of the tooth. They are designed to eliminate the fibrous attachment where a periotome does not have sufficient strength.
Nobel Biocare makes mention of their new all-ceramic implant design that uses a zirconium based surface in their annual report (page 35). Clinical trials are in progress. It seems interest in Zirconium Oxide based implants is on the rise by the big companies. Definitely a trend to keep an eye on.
Osseo Scientific LLC has added a collection of low temperature osteotomy drills to their product line. They claim that the unique design allows for lower force osseous penetration and therefore less heat generation. They display an interesting temperature graph as evidence of this.
Med-3d has released a CAT-Scan based 3-D implant planner similar to many other software packages previously profiled, however they use a very unique XYZ positioning device to drill the titanium drill tube holes in the patient stent – basically a dental surveyor on steroids.
XCPT is an implant treatment planning program created by a Florida periodontist. The dental practitioner can import a patient`s radiographs (panoramic, peri-apicals) and then using the implant templates and other tools visually plan a patient`s treatment.
MIS Implant Technologies Ltd.`s Abrahmi Drill Guide Kit is a drill guide kit that allows for optimal inter-implant spacing, angulation and parallelism.

MIS`s Yeung Bone Harvest kit consists of a set of four drills with a slot that allows for the accumulation of autogenous bone during osteotomy preparation. The drill size ranges are: 2.80mm, 3.20mm, 3.80mm and 4.50mm.
Materialise`s SAFE System combines drilling guidance, implant insertion guidance and depth control. Simplant is used to plan the optimal position of the implants and then this plan is transferred to the SAFE system which produces a physical guide and a surgical report to guide the surgeon during implant placement.
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. It`s selective cutting action allows for mimimal soft tissue damage, especially useful for opening sinus windows during lateral sinus lift procedures. 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.
Tactile Tech has introduced the Implant Location System (ILS) which applies tactile sensing technology to offer intra-oral image-guided navigation specifically for dental practitioners. It is a computer-guided sensing, navigation and guiding suite for placement of dental implants designed both for the general practitioner and the expert. It provides safety and restorative accuracy without introducing the great complexity of other navigation systems.
