and Dr. Niznick’s 33-year history of innovation in the implant industry, with over 30 patents including the internal, conical connection in 1986 – the cornerstone of modern dental design. Today, Implant Direct continues those traditions through its commitment to provide high quality products at value-added prices with simplified surgical procedures and versatile prosthetic options. The company releases numerous new product lines and line extensions each year while also continually improving its existing product designs, manufacturing processes and online support.

Implant Prosthodontics: Past, Present, and Future

Dr. Niznick graduated from the University of Manitoba Dental School in 1966 and earned a Master’s degree in prosthodontics from Indiana University in 1968. He has been awarded 36 U.S. Patents and has received honorary doctorates from the University of Manitoba and Tel Aviv University. Dr. Niznick can be reached at Disclosure: Dr. Niznick is founder and president of Implant Direct. He developed the Core-Vent system discussed in this editorial.

Research published in 1983 documenting the long-term success of titanium screw implants which, by a process called Osseointegration, became firmly attached to bone, changed the course of implant dentistry.1,2 The Brånemark external hex implants used in that study offered a single abutment option for a screw-retained attachment of a hybrid prosthesis for restoring edentulous jaws.

Reprint from: Journal of Cosmetic Dentistry, Summer 2012

In 1986, Core-Vent introduced the Screw-Vent implant, featuring an internal lead-in bevel, hex, and threaded connection.5 This became the cornerstone of modern implant design and is today referred to as a “conical connection.” This advance paved the way for greater use of cemented restorations, which resulted in acceptance by general practitioners of fixed prosthetics on implants, as the procedures more closely paralleled the restoration of natural teeth. The internal connection provided a greater tactile sense when seating an abutment, thus eliminating the need for x-rays to determine whether transfers and abutments were fully seated. It also allowed for smallerdiameter implants with adequate strength to be designed, thereby expanding clinical applications.

difficult task has been to overcome the stereotypical thinking that there is a direct relationship between an implant’s cost and clinical success. Many implant companies use paid opinion leaders in private practice and academia, along with large sales forces, to perpetuate this myth. Today, however, the Internet has leveled the playing field, making it possible to educate more dentists to the benefits and features of “appropriately priced” products— some with cross-compatibility to the surgical protocols and prosthetic connections with which dentists are familiar. Offering application-specific implants with All-in-1 Packaging simplifies implant selection, eliminates confusion with ordering ancillary products, and provides unprecedented value, thus allowing more patients to Implant dentistry is a prosthetic benefit from implant dentistry. discipline with a surgical component; Additionally, online education—aided thus, Core-Vent’s system was designed by live surgical videos, lectures, for simplified surgical procedures, product comparisons, and, especially, allowing general practitioners to online ordering—is changing the learn implant placement. implant industry’s dynamics. The key to proper training was to establish educational courses that focused on case selection and treatment planning.

Today, most patients know about the benefits of implant solutions for their missing teeth, resulting in more restorative dentists making the investment in education to be able to offer these services in their practices.

The Implant-Abutment Connection: The Key to Prosthetic Success In 1991, Compendium published an article by Dr. Gerald Niznick (Vol. XII, No. 12) with the same title as the heading above. The principles Niznick expounded 20 years ago are even more valid today with Implant Direct’s broad line of application-specific and industry-compatible implants shown by the company’s one- and two-piece implants below. Dr. Gerald Niznick, a prosthodontist, revolutionized the implant industry with the introduction of the ScrewVent® implant (now sold by Zimmer Dental) with its patented internal connection platform that featured a lead-in bevel for lateral stability and an internal hex for insertion and accurate transfer capabilities (Niznick U.S. Patent #4,960,381). This implantabutment connection has become the cornerstone of modern implant design, licensed to eight implant companies and copied by many others following the expiration of the patent in 2007. One such replication is the lead-in bevel/internal hex of Nobel Biocare’s NobelActive™ implant. Whether the lead-in bevel is 45 degrees, as in the original Screw-Vent implant, or 8 degrees (Straumann®), 11 degrees (Astra™) or 12 degrees (NobelActive), a “conical” interface provides lateral stability, reducing the occurrence of

screw loosening in comparison to butt joint connections (tri-lobe and external hex implants). The original 45-degree bevel, present in Implant Direct’s Legacy™ System, has the added advantages of increased strength and improved tactile sense for seating an abutment without the need to take an X-ray as recommended by Nobel Biocare for NobelActive. Dating back to the early 1980s, Niznick’s focus has been to provide high-quality products at value added prices with simplified surgical procedures and versatile prosthetic options. Following this strategy and with a strong focus on use of the Internet for education, sales and marketing, Implant Direct has been credited with bringing about a pricepoint shift in the implant industry in just four years. The industry changes and recent economic factors have prompted many dentists to have a “reality check” on the best options for their practices and patients.

Today Implant Direct offers the broadest line of implants and abutments in the industry, many incorporating Niznick’s patented innovations including double-lead body threads for faster insertion with coronal quadruple-lead microthreads for reduced stress and increased stability (Niznick U.S. Patent #7,677,891). The company philosophy has been to combine clinically proven implant design concepts with “All-in-1 Packaging” for maximum value and convenience. While the items included vary by product, All-in-1 Packaging reduces or even eliminates the need to purchase additional items at the restorative phase of treatment (Niznick U.S. Patents #7,396,231 and #7,785,107). The application-specific SpectraSystem® includes ScrewPlant® bonelevel and ScrewPlus® tissue-level implants with the same internal hex/external bevel connection as well as several unique one-piece implants. The one-piece implants provide increased strength, allow use of smaller (3 mm) diameters while shortening chair time and reducing both cost and inventory requirements. The GoDirect™ one-piece implant features a platform that is compatible with Zest Anchor’s LOCATOR® Fig. 1: Implant Direct’s expansive product offering.

Implant Direct has recently launched a complete line of GPS™ abutments that are compatible with the LOCATOR system. Another Spectra-System one-piece implant, ScrewIndirect™, provides a multi-unit abutment platform for bar overdentures and fixed-detachable, hybrid prostheses — making Teeth-in-1Day™ a practical and cost-effective procedure. In addition, Implant Direct offers implant solutions with industrycompatible internal hex, tri-lobe and octagon connections. The Legacy System offers surgical and prosthetic compatibility with Zimmer Dental’s Tapered Screw-Vent developed by Niznick in 1999. Legacy abutments are compatible with several other internalhex implant systems, such as BioHorizons®, BlueSky and MIS®.

Implant Direct’s RePlant®, RePlus® and ReActive™ Tri-lobe system provide prosthetic compatibility with for Nobel Biocare’s Replace implants and Implant Direct’s SwishPlus™ and SwishPlant™ internal octagon tissue-level implants provide prosthetic and surgical compatibility for Straumann customers. Implant Direct does not make clones. It designs updated versions of these popular competitors’ products by adding features to improve self-tapping insertion as well as increase strength and surface area. Implant Direct is in the process of increasing its manufacturing capacity from 40 CNC machines to 68 to keep up with the demand for its products. The additional manufacturing space will allow Implant Direct to offer CAD-milled titanium bars, custom abutments and surgical guides. In addition to an already broad product line, Implant Direct will be launching the InterActive implant system with prosthetic compatibility

An Interview with Implant Direct Gerald A. Niznick, DMD, MSD, President and CEO

INSIDE DENTISTRY (ID): How much has really changed about the implant industry since you started Core-Vent Corporation in 1982, Paragon in 1997, and Implant Direct in 2004?

targets the established Premium-priced product lines with systems that offer surgical and prosthetic compatibility for a non-negotiable list price of $150 to $200. We provide added value with All-in-1 Packaging that typically includes a cover screw, healing collar, transfer, and either final or temporary abutment. Quality and a broad line of products are essential for Implant Direct’s “Value Strategy” to succeed. This is made possible, even at relatively low prices, by operating the industry’s only “lights-out” 24/7 manufacturing facilities that can be viewed on five online cameras on our website. This strategy has forced many of the premium-priced companies to aggressively discount to volume purchasers to maintain their best customers.

(ID): You have been widely recognized and honored for your contributions to the dental implant market. Which of these contributions GERALD A. NIZNICK (GN): The success do you think made the biggest impact on of a broad range of implant designs, surfaces, how implant dentistry is practiced today? and materials is now well established in the dental literature. What has changed, (GN): The original Core-Vent (1982) twoespecially in the last decade, is that implant stage implant had a hex hole into which a companies have segmented into three variety of application-specific prosthetic categories in order to find their USP (unique abutments could be cemented. This was in selling proposition). Premium Priced Players contrast to the Brånemark implant which did differentiate their products based on claims not come on the US market until a year later of research and the support of paid opinion with only one multi-unit abutment for leaders. This research is designed to create edentulous screw-retained bridges. That sound bites for marketing, comparing a concept of versatile prosthetic applications company’s new and improved products to contributed to making implant dentistry part their old ones without providing any clinical of conventional fixed prosthetics with studies to show a significant improvement in cemented crowns and bridges. The internal success. Each new version is accompanied hex connection (Niznick US Pat. #4,960,381) with a price increase, now reaching an and all the screw-retained abutments that I average of about $350 to $450 per implant. developed thereafter accomplished the same Discount Priced Players sell on price alone, prosthetic versatility while offering offering a limited range of implant designs retrievability. When these types of two-piece and dimensions. These companies vary their abutments were developed for the external implant prices and volume discounts based hex implants, it became apparent that the on the market and the negotiating skills of internal connection offered greater stability the dentists. With an average list price of and esthetics. The industry was slow to $100 to $150 and substantial discounts for change over because the internal connection volume purchases, the dentists purchasing was patent-protected, whereas any company these products are prepared to accept could make an external hex. In 1999, I solved possible compromises in quality, precision, the problem of achieving high initial stability packaging, and limitations in implant or in soft bone with the development of a softabutment options in order to get what they bone/hard-bone surgical protocol, inserting perceive as a bargain. Value Priced Players the newly designed tapered Screw-Vent in is a segment of the market that Implant undersized sockets prepared with straight Direct created in 2006. Implant Direct step drills. Inserting a tapered implant into an

Reprint from: Inside Dentistry, June 2012 undersized socket created with a straight step drill led the way for immediate loading of implants. When dense bone was encountered, the size of the socket would be enlarged, eliminating the need for bone taps and allowing selftapping insertion in both soft and dense bone. In addition, I am especially proud of the 5-year clinical study conducted at 32 Veteran’s Affairs centers that included 900 patients receiving over 2,800 implants. This was the largest dental implant study conducted worldwide and special issues of Journal of Periodontology and Journal of Oral and Maxillofacial Surgery were dedicated to publishing the results, which added significantly to dental implant knowledge. (ID): You’ve built Implant Direct into an international company with hundreds of employees and distributors in more than 30 countries. How would you define your approach to launching and successfully running a business? (GN): Building and running a successful business in a relatively short time takes production capacity, an innovative product line, the right “go-to-market” strategy and a dedicated team of knowledgeable people. After selling Core-Vent/Paragon Implant Company to what is now Zimmer Dental in 2001, I retired for a few years. In 2004, Zimmer chose not to renew the lease on my Los Angeles factory and moved their manufacturing closer to their corporate headquarters near San Diego. This presented an opportunity to re-occupy the factory I had built in 1994 for producing implants and re-hire 80 of Zimmer’s top machinists and QA specialists, many of whom had worked for me for years before the sale to Zimmer. In the next 3 years, my team developed the lights-out manufacturing processes that assured efficiency and quality. Together with my design engineering team, I developed the Spectra-System® of six 1 and 2-piece implants, all with the same body and, therefore, surgical protocol, but with different platforms and packaging for different clinical applications. This created the industry’s first application-specific implant system with each implant appropriately priced — low enough that the premium- priced implant companies could not routinely discount

to match that price. This formula of offering innovations, quality, and value was just what the industry was waiting for and the 2008 economic recession made the need for “appropriate” priced implants even more compelling. To keep the selling expenses low, I focused on the internet for education and sales. Demand grew globally for the products and, today, Implant Direct has almost 150 people in North America providing sales, customer service, and technical support. We opened an office in Zurich to support our direct sales forces in Germany and Italy, as well as shipping to our distributors throughout Europe.

One-piece, Application Specific Implants for Treatment of Narrow Ridges There are many clinical situations in which bone limitations may necessitate use of a narrow diameter. The term “Mini-implants” is generally attributed to implants with diameters of 3mm or less, 2.4mm and 2.8mm being the most popular diameters. Mini-implants are available from many companies with either Ball, ERA or O-ring abutment platforms for retention of over-dentures. There are also 3.0mmD 1-piece implants with application specific platform options available (Implant Direct, Calabasas, CA): GoDirect™ with a Zest LOCATOR® compatible platform for retaining over-dentures with GPS™ attachments, ScrewIndirect® with a multi-unit platform for screw-retained restorations and ScrewDirect® with a tapered abutment for cemented restorations. Implants less than 3mm have not received FDA pre-market approval for claims of being a permanent tooth replacement, although they can be marketed with claims of “long-term” usage, an upgrade from their prior classification as temporary solutions. Traditional mini-implants have a sharp, pointed apex to allow insertion in a socket not fully prepared to depth. These implants have gained popularity in part due to their relatively low cost compared to traditional implants from the major implant companies and because the narrow diameter encourages placement without laying a soft tissue flap. Both of these “simplified” surgical procedures have risks and

drawbacks that should be considered. Preparing a socket half the depth of the implant, and screwing in the pointed implant into unprepared bone will undoubtedly increase initial stability but, given the narrow diameter of mini-implants, there is an increased risk of implant fracture if

Tapered Implants with a rounded apex require preparation of the socket to full depth, giving the dentist the opportunity to determine the density of the bone. If soft bone is encountered, the tapered implant can be inserted into the undersized socket expanding and compressing the bone for increased stability. If dense bone is encountered, the dentist follows up with a final sizing drill closer to the diameter of the implant, eliminating the need to remove the implant after insertion is initiated.

Narrowing the apical end to a point reduces the strength of the implant compared to the same diameter implant with a rounded apex because of greater metal diameter in the lower half of the implant. A recent study published by CLINICIANS REPORT, Dr. Gordon Christensen’s research group, compared fracture strengths of the 3.0mm and 3.7mm GoDirect 1-piece implants to commercially available 2.4mm and 2.9mm mini-implants.

dense bone is encountered. The alternative procedure if dense bone is encountered is to unscrew the implant, prepare the socket to its full depth and re-insert the implant.

2.9mm and 3.0mm implants, there was a 42% greater strength. The 3.7mm GoDirect demonstrated 30% greater strength, which is more proportional to the 23% increase in diameter compared to the 3.0mm GoDirect. Wider implants also provide greater surface area, thereby reducing the number of implants needed to provide the same amount of load carrying capabilities. The difference in diameter between 2.4mm and 3.0mm is only 0.6mm/2 = 0.3mm (0.012”) on each side, which is about the thickness of 3 human hairs so the diameter of the osteotomy required to place each of these diameter implants is not significant, especially with tapered implants in soft bone. Mini-implants gained popularity in part to the belief that narrower implants better facilitated insertion without requiring a soft tissue flap. This is a misconception because if the narrow implant was selected because of a narrow ridge, it is exceedingly unpredictable to blindly place an implant in the center

of the narrow ridge without causing buccal or lingual perforations. On the other hand, if the ridge is wide enough to predictably place the implant flapless in the center of the ridge, a Mini-implant, if placed in the center of the ridge, would only engage cancellous bone. A 3.7mm or wider implant would provide greater strength and stability in this situation, and fewer implants would be needed to achieve the same or even greater surface area for load support. A slight increase in implant diameter from 2.4mm to 3.0mm can also provide an adequate dimension as it emerges from the crest of the ridge, to provide a more natural emergence profile for cemented restorations and an adequate width for multi-unit (screw-retained) restorations. The decision to place an implant without laying a flap depends on the clinician’s ability to visualize the ridge width in order to determine adequate bone to support the implant. This

cost of the procedures, which obviates the savings that have perpetuated the use of Mini implants. Once the decision is made to lay a flap and visualize the ridge width, narrow lower edentulous ridges can often be flattened to create adequate width to place a 3.7mmD implant. The visualization allows placement in the center of the ridge without perforations or compromise to the labial or lingual cortical plates. In narrow maxillary ridges, laying a flap provides opportunities to surgically spread and widen the ridge before implant placement, with or without bone grafting. A 3.0mm, evenly tapered screw implant with a rounded apex can be inserted into an undersized osteotomy using only a 2.3mmD drill, gradually expanding the cortical walls of the socket, compressing the soft bone and increasing mechanical retention for initial stability. (G. Niznick: Clinical Oral Health 2000 “Achieving Success in Soft Bone”).

In the case shown, four 3.0mmD, 13mmL GoDirect™ implants where placed free-hand with a flapless surgery in a rather narrow ridge by a very experienced clinician. The X-ray reveals that there was more than adequate bone height to allow for removal of 4-6mm of crestal bone to achieve a wider ridge since the symphysis widens towards its base. Visualization of the edentulous ridge would have assured optimum placement in the center of the modified ridge without risking compromise to the buccal or lingual cortical plates. These 1-piece implants provide a cost-effective option for stabilizing overdentures and with the launch of the 3.0mmD with a pointed apex, will provide dental professionals a full range of diameter and surgical options with this system. As can be seen in the X-ray, the GoDirect implant is The internal threads of the GoDirect implant allow the addition of an extender (left) internally threaded, allowing subsequent attachment of different abutment if needed to accommodate soft tissue height or options if required for tissue overgrowth or a change of treatment options, conversion to a multi-unit abutment (right) for such as conversion to a screw-receiving abutment. treatment plan flexibility.

The publication of the 15 year results with Brånemark external hex screw implants (Adell R., Brånemark P-I., et al: Int. J. Oral Surg. 1981 10:387-416) documented the long-term success with osseointegrated titanium implants. The Core-Vent (1982) internal hex implant (Niznick G. US Pat. # 4,431,416) with cemented abutments brought versatile prosthetics to implant dentistry but it was the Screw-Vent® (1986) internal hex-thread connection with a lead-in bevel (Niznick G. US Pat. #4,960,381) that brought together stability and detachability. This connection facilitated the

design of narrow diameters implants and its stability made cementation in partially edentulous jaws the treatment of choice. This type of implant-abutment connection became the cornerstone of modern implant design and is today referred to as a conical connection in the most popular implant systems. Before the patent’s expiration in 2007, this connection was licensed to eight different implant companies, and since, has been incorporated into most implants including the NobelActive™ and NobelReplace™ Conical Connection implants. Whether the lead-in bevel is 45 degrees, as in the original Screw-Vent (Zimmer Dental), MIS or BioHorizons implants, 8 degrees (Straumann®), 11 degrees (Astra™) or 12 degrees (NobelActive™), a “conical” interface provides lateral stability to reduce the occurrence of screw loosening in comparison to butt joint connections (tri-lobe and external hex implants). One problem with increasing the slope of the lead-in bevel is that it moves the anti-rotational feature (internal hex) farther down the internal shaft, often requiring X-rays to verify full seating of the abutments. It also thins the walls of smaller diameter implants, increasing the risk of fracture under lateral load. The new InterActive™ system of conical connection implants and abutments from Implant Direct (launch anticipated soon) provides a platform compatible to the NobelActive and NobelReplace Conical Connection. The InterActive abutments incorporate design modifications to help ensure full seating of the abutments without the necessity of confirming radiographs. This is accomplished by lengthening the hex and shortening the bevel so that a lack of full seating is readily apparent as the hex will be visible above the implant. Two other features also assist full seating. A piloting feature has been added to the bottom of the abutment’s hex to help guide insertion and an internal thread has been added to the abutment shaft to retain the screw while the abutment is rotated to a full seat in the implant’s deep hex. The contour of the InterActive abutments, transfers and healing collars have been designed for improved soft tissue management with a concave emergence profile. The InterActive implant is available in four diameters with the same platform for the 3.2mm & 3.7mm implants

as the NobelActive 3.5mm implant, and the same platform for the 4.3mm and 5.0mm implants as used with the NobelActive implants of these diameters. The platforms are colorcoded for easy identification with matching anodized cover screws, healing collars and transfers. The body of the InterActive implant matches that of the successful Legacy2 implant with double lead body threads over the tapered 2/3rds of the implant for faster insertion. These threads are flat based and become progressively deeper towards the apex for increased surface area. Three long vertical cutting grooves and tapered body with a round apex ensure the implant will follow the trajectory of the osteotomy and allow self-tapping insertion using dense-bone drills without the need for a bone tap. An additional design improvement incorporated into these new implants is the combination of
