Free hand implants require a great deal of skill, time and effort for a dentist to pull off. Not only this, the consistency from patient to patient is something which is clearly lacking if an implant is done by hand, which begs the question of whether or not there is a better way. The GuidePro3D utilises disruptive technology; additive layer manufacturing, commonly known as 3D printing, to be able to print out a custom frame and cartridge (as pictured) in
The esthetic quality and integrity of every single implant is inarguably influenced by the peri-implant tissue shaping of the implant healing abutment itself. Having the ability to be able to make highly accurate personalized healing abutments in a matter of minutes using the latest CAD/CAM software is a great tool for implantologists to have. The above picture and video shows how simple the process is to make a personalized healing abutment shaping block. This will take around 30 seconds
Versah, a company started by Michigan Periodontist, Dr. Salah Huwais , have designed a set of multi-fluted osseodensification burs for implant placement. Osseodensification is a novel, biomechanical, non-excavation preparation method that compacts and autografts bone during the osteotomy. The burs will remove bone when spun clockwise, however when spun counterclockwise they collect and compact bone chips into the osteotomy wall and result in greater local bone density and higher insertion torques. They can also be used for internal sinus lifts
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
Researchers at the California Institute of Technology have developed a Palladium based glass that is an alloy of the noble metal palladium, a small fraction of silver, and a mixture of other metalloids—has shown itself in tests to have a combination of strength and toughness at a level that has not previously been seen in any other material. “Our study demonstrates for the first time that this class of materials, the metallic glasses, has the capacity to become the toughest
Sonitus Medica of San Mateo, California has received FDA clearance for SoundBite, a dental hearing aid for people with deafness in one ear. The system works much like a cochlear implant, except for the implantation. A behind the ear device wirelessly transmits audio from the affected ear to a little receiver attached to a tooth that resonates the teeth, that in turn stimulate both cochlea. The removable In-The-Mouth (ITM) device showed no long-term effects on dental or periodontal soft or
The use in spine surgery of bone-growth proteins like Medtronic Inc.’s product Infuse has led to widespread nationwide increases in hospital charges ranging from 11% to 41% above conventional surgical costs, researchers found. The researchers studied the results of a broad U.S. sample of 328,000 spine surgeries from 2002 through 2006. They report their findings this week in JAMA, the Journal of the American Medical Association. The authors, from both Brigham & Women’s Hospital in Boston and from Yale, also
Keystone Dental`s Genesis Implant has been cleared by regulators. The implant system features a patented BioSpark™ surface, a nano-surface that mimics the structure of bone, creating a healing environment to optimize bone integration. In addition, the unique AnaTite™ process results in the first-ever marketed pink implant collar and a complete line of pink prosthetics. The aesthetic breakthrough of the AnaTite process allows the Genesis System to project a more natural hue through the patient`s gum tissue for a more natural
Dental Implant Prices Decline by 3.3% in Europe as Practitioners Purchase Implants From Low-Cost Manufacturers, According to Millennium Research Group. Average selling prices of dental implant fixtures and final abutments have decreased 3.3% and 8.1%, respectively, over the past year. This occurred as dentists attempted to maintain profitability during the economic crisis by demanding greater discounts and increasingly purchasing implants from low-cost manufacturers.
Because children and adolescents are particularly vulnerable to radiation, doctors three years ago mounted a national campaign to protect them by reducing diagnostic radiation to only those levels seen as absolutely necessary. Not only do most dentists continue to use outmoded X-ray film requiring higher amounts of radiation, but orthodontists and other specialists are embracing a new scanning device that emits significantly more radiation than conventional methods, an examination by The New York Times has found. Some orthodontists now use
Nobel Biocare has been sued by a California dentist seeking class-action status on behalf of dentists whose patients have suffered complications such as bone loss from one of its products namely the NobelDirect dental implant. The suit by Jason M Yamada, a periodontist, seeks compensation for dentists who have had to perform surgery on their patients, or pay for restorative surgery, after complications from the implants, which it said were defectively designed. The suit proposed a class action to cover
The New York Times has published a consumer-oriented article on dental implants. They discuss the options: dental implant versus bridge and the coverage dental insurance companies provide for this service. This well written article is an excellent introduction to dental implants especially useful to share with patients considering this treatment.
Scientists at North Carolina State University have developed a new lightweight “metal foam” with elasticity similar to bone that could lead to a new generation of medical implants, likely overcoming a range of problems associated with devices currently in widespread use. “Our composite foam can be a perfect implant material to prevent stress shielding,” said Rabiei, the lead researcher. “This is because the modulus of our composite foam is matching perfectly with that of bone. That means when the implant
Cerapedic`s i-FACTOR bone graft is the only biologic bone graft that combines a unique anorganic bone mineral (ABM) and small peptide (P-15™) to act as an attachment factor for specific integrins on osteogenic cells. This novel mechanism of action enhances the body’s natural bone healing process resulting in safe, predictable bone formation at a lower cost than growth factors. ABM/P-15 has been in human clinical use for more than thirteen years in an estimated 500,000 patients worldwide. P-15 is a
Dr. Kirk Johnson, an Anchorage Alaska dentist spread holiday cheer by performing an unusual operation on an unusual patient. A bald eagle came to Anchorage`s bird treatment and learning center with a severely damaged beak possibly caused by fishing line. Dr. Johnson made a mold using dental impression material with which he fashioned a temporary beak implant.
Developed by a practicing dentist, the Zosseo Universal Implant Drill Stop kit allows for osteotomies that do not require as precise a visualization for depth control. It has a single width for all drills – only requires length determination for the osteotomy and has precise depth penetration – eliminating the risk of over drilling and potential sinus or nerve complications.
The million or so artificial hips and knees implanted each year in the United States are normally not guaranteed. Instead, the costs of replacing implants that fail early because of design or mechanical problems — devices that sell for as much as $15,000 each — are largely paid by Medicare, insurance companies and patients. Implants can fail for many reasons, but if only a small percentage of them fail prematurely because they are substandard, the costs to taxpayers, policyholders and
A Las Vegas dentist has filed a FDA Med Watch report regarding the integrity and therefore sterility of Nobel Biocare Replace Implants. To quote from the report: “I have experienced substantial and unexplainable failures with Nobel Biocare`s (“Nobel”) Replace(TM) Implants. Of 88 consecutively placed implants,34 required removal due to pain or infection for a failure rate of 38.6% (Attachment #1). I doubt these failures are caused entirely by my case selection or surgical skill because I also recorded the clinical
With economic pressures affecting millions of Americans, dentists may have noticed a drop in patients opting for a brighter smile, but they are seeing another phenomenon: a rise in the number of teeth grinders. “I’m seeing a lot more people that are anxious, stressed out and very concerned about their financial futures and they’re taking it out on their teeth,” said Dr. Steven Butensky, a dentist with a specialty in prosthodontics (aesthetic, implant and reconstructive dentistry) in Manhattan. One of
Numerous dental implant company`s have sprung up over the last 3 years that aim to deliver either very similar designs or almost direct copies of established company`s design. These clone implants are often substantially less expense i.e. 1/4 the cost of full service dental implant company`s implants. In addition to mimicking the implant, they have also expanded into compatible prosthetic parts and coverscrews. Especially prominent clone makers Blue Sky Bio (Clone: Straumann, Nobel Biocare and Zimmer) and Dr. Niznick`s Implant
The New York Times health section recently published an informative article on the trend away from using bridges to replace missing teeth and toward replacement with dental implants. The comments section of this article is also particularly lively and well-worth reading.
The Powertome 100S from Westport Medical is a powered periotome used in the extraction of teeth. It features a powered periotome blade that is precisely guided in the periodontal ligament by a microprocessor controlled, solenoid actuator. It features a footswitch activated handle similar to other dental hand pieces and the operation, actuation and sterilization are therefore intuitive.
A former US Army orthropedic surgeon, Dr. Timothy Kuklo, previously accused of falsifying a study on a bone growth product used on severely injured Iraq war veterans has resigned his teaching position at Washington University in St. Louis. He was placed on leave earlier this year while the university investigated charges against him. Medtronic, a maker of the bone growth product Infuse, also suspended his consulting contract. The company paid him nearly $800,000 the last few years. An investigation last
Patients who subconsciously take out stress on their teeth at night is nothing new. But the recession is. A periodontist, Dr. David Samuels reports that he can practically see the impact of the economy in his patients’ X-rays. “On these films right here that we’re looking at, this area right here represents the top of the tooth – a fracture of the top of the tooth from clenching and grinding,” Samuels says. “You also see flattened surfaces on tops of
Manhattan Scientifics has announced that its NanoTitanium product has been approved by the FDA. The patented new form of titanium metal originally developed by Russian scientists in concert with scientists at the Los Alamos National Laboratory is expected to significantly improve dental implants. Studies have shown that bone integrates with these new metals up to 20 times faster than with conventional metals. Patients should experience shorter post surgery healing times and a more reliable integration of these new implants into
Brookhaven Science Associates, the company that operates and manages the U.S. Department of Energy’s Brookhaven National Laboratory (BNL), and Biosurface Engineering Technologies, Inc. (BioSET), have been issued a U.S. patent on a synthetic peptide, called B2A. B2A enhances the effects of a tissue growth factor known as bone morphogenetic protein 2, or BMP-2.

It is the ninth most plentiful element present in the Earths crust. It has been found in meteorites and detected in the sun and class M stars. The Apollo 17 moon mission brought back
Scientists at Oregon State University have found a gene involved in enamel production. In the latest research, published in Proceedings of the National Academy of Sciences, a team led by Chrissa Kioussi and Mark Leid bred mice that lacked a gene known as Ctip2. The gene, called Ctip2, is a “transcription factor” that was already known to have several functions – in immune response, and the development of skin and the nervous system. Scientists can now add tooth development to
Université de Montréal Researchers have modified metal surfaces such as titanium producing a sponge-like pattern of nano pits that increased growth of bone cells, decreased growth of unwanted cells and stimulated stem cells, relative to untreated smooth ones. In addition, expression of genes required for cell adhesion and growth were increased in contact with the nanoporous surfaces. “We demonstrated that some cells stick better to these surfaces than they do to the traditional smooth ones,” says Dr. Nanci. “This is
SinusTech America have released a sinus lift kit that features a unique reamer design that cuts, lifts and elevates the floor of the sinus with minimal danger of damage. They claim that the technique minimizes the possibility of damage to the sinus membrane, forms an appropriate sized osteotomy site for implant placement and allows for the placement of bone grafting materials into the elevated sinus cavity.
A study in the November issue of the Journal of Endodontics claims that dental implants require much more follow-up treatment than root canals, according to a study by researchers at the University of Alabama at Birmingham. Their study results reported that the success rate for the dental implants was 98.4 percent; for root canals it was 99.3 percent. However, 12.4 percent of the dental implants required additional interventions, compared with 1.4 percent of the root canals. “Considering these results in
UC San Diego bioengineers and material science experts used a nano-bio technology method of placing mesenchymal stem cells on top of very thin titanium oxide nanotubes in order to control the conversion paths, called differentiation, into osteoblasts or bone building cells. Mesenchymal stem cells, which are different from embryonic stem cells, can be extracted and directly supplied from a patient’s own bone marrow. The researchers described their lab findings in a paper published this week in the Proceedings of the
Keystone Dental, funded by private equity firm Warburg Pincus, has settled an unfair competition lawsuit from Noble Biocare for $2million. “The settlement terms provide for Keystone Dental to pay $2 million to Nobel Biocare and that Keystone Dental not hire or solicit any current Nobel Biocare employee through February 1, 2009,” the world`s largest maker of dental implants said in a statement. Nobel Biocare filed a lawsuit in late 2007, saying Keystone Dental systematically targeted and hired Nobel Biocare`s sales
The Wall Street Journal is reporting that Medtronic`s `Infuse Bone Graft` has been linked to life-threatening complications in dozens of patients. The FDA warned surgeons in July that it had received reports of life-threatening complications associated with using the product in surgeries on the cervical spine, around the neck. The agency said it received 38 reports over four years of side effects, mainly swelling of neck and throat tissue, which resulted in compression of the airway and other structures in
Dr. Schubert Sapian has designed a innovative root removal system that extracts the entire root without sectioning. A specialized extraction screw is driven into the largest canal then a cushioned silicone fulcrum tray is placed over the adjacent teeth and a pry bar is used to apply vertical pressure to the root resulting in its atraumatic extraction.

Having already successfully marketed a copy of Nobel Biocare`s implant designs. Read this interview with an European trade journal for interesting details of the strategy.
Canadian researchers at the NRC Industrial Materials Institute (NRC-IMI) in Boucherville, Quebec have developed a porous titanium foam implant said to mimic a metallic version of bone. The titanium foam is made by mixing titanium powder with a polymer, and then adding foaming agents that expand the polymer when heated. Later, through a high-temperature heat treatment, the polymer is removed and the titanium particles are consolidated to provide mechanical strength to the porous structure. Porous titanium had previously been used
Canadian researchers at the University of Alberta have found the surface nanocrystallization of a metallic material is an effective approach for modifying the surface energy of metals. “Our results demonstrate that the combination of surface nanocrystallization and thermal oxidation treatment is a promising approach to suppress the formation of infectious biofilms on metallic materials, thus providing a surface technique to minimize bacterial biofilms on implant surfaces for improved orthodontic and orthopedic applications” says Li the lead researcher. This surface modification
3M ESPE`s digital dental impression system has been selected as a bronze award winner in the International Design Excellence Awards for 2008. This digital dental impression system captures continuous 3D video images to create precise 3D dental models. Intended for use by dentists and hygienists, it eliminates the discomfort of traditional methods and improves communication between patients and dentists by allowing immediate chair-side review. To create a digital impression, the dentist positions the wand in the patient`s mouth and glides
A report by scientists from the Netherlands published in the FASEB Journal identifies a compound in human saliva that greatly speeds wound healing. Scientists found that Histatin, a small protein in saliva previously only believed to kill bacteria was responsible for the healing. Because saliva is a complex liquid with many components, the next step was to identify which component was responsible for wound healing. Using various techniques the researchers split the saliva into its individual components, tested each in
Dr. Jong-Ho Lee, a Korean dentist, has patented his design for a free-angled screwdriver and abutment. The system addresses the prosthetic problem of access screw hole placement. The free-angled driver consists of 2 to 3 sections connected using universal joints which allows the unrestricted rotation of the free-angled driver at any angle. The free-angled driver eliminates the need for a straight channel to access the abutment screw. The abutment screw can be screwed and unscrewed using the curved channel up
Michael Mastromarino, the leader of the body-snatching ring that plundered the corpse of broadcaster Alistair Cooke apologized to the victims as he was sentenced to 18-54 years in prison. “I am deeply sorry for all the emotional pain I have caused to donor families and donor recipients,” he told the Brooklyn Supreme Court in New York. Mastromarino once ran a dental practice on New York`s Fifth Avenue specializing in dental implant surgery. But he was forced to surrender his dental
Novel processing of commercially pure titanium (CP Ti) has produced exceptional mechanical properties and recent clinical trials have proven its superior biocompatibility as well. CP Ti is desirable mainly for its superior biocompatibility, but suffers from low strength compared to either steel or alloyed titaniums. Severe plastic deformation (SPD) processing aims to get microstructural refinement to a level not achievable with traditional processing yielding nanocrystalline titanium. Fatigue life has nearly doubled and although damage tolerance suffered, the levels are still
Bioengineers and bioscientists at Rice University and Radboud University in Nijmegen, Netherlands, have shown they can grow denser bone tissue by sprinkling stick-like nanoparticles throughout the porous material used to pattern the bone. To grow new bone, tissue engineers typically place bone cells on porous, biodegradable materials called scaffolds, which act as patterns. With the right chemical and physical cues, the cells can be coaxed into producing new bone. As the scaffold degrades, it is replaced by new bone. “Ideally,
