The More Complex an Organism is, the Lesser the Capacity of its Body to Perform Regenerative Processes The biological process, or self-sufficient capability to restore deficient tissue is referred to as the ability for regeneration. In contrast to repair, i.e., wound healing, whereby the original biological structure is not fully rebuilt, the goal of regeneration is to completely restore the structure and function of tissue that has been lost or injured. This ability has continuously diminished as creatures have evolved and the complexity of these organisms has increased. Compared to the “champions” of regeneration, present day cnidarians, which can re-grow severed extremities and internal organs that have been lost, this capability in humans, without additional support, is limited to a few types of external tissue. When the Body’s Own Healing Process “Overshoots its Target“ When a person’s tissue is injured, the body’s repair process, rather than regenerative process, begins. Here, the body does not primarily attempt to restore the original state and function of the tissue, but rather to close the wound as quickly as possible. This spontaneous healing process involves the formation of connective tissues that penetrate deeply into the original tissue and also remove “good” tissue in the process. During such a “radical” healing process, it is possible that even important functions are permanently destroyed. Regeneration Can be Guided with Medical Treatment To prevent this type of overcompensation in the healing process wherever possible, strong antiinflammatory drugs are administered today, such as in cases of back injuries. This prevents this destructive process from occurring, in turn making it possible to preserve part of the nerve tissue and mitigating deficits such as paralyses. In medical terms, regeneration entails assisting desirable tissue formation processes, and guiding and limiting the repair mechanisms involved in wound healing as to not impede the regeneration of intact, functioning tissue. foCal point Fig. 1: The cnidarians (pictured here, a green anemone, anthopleura xanthogrammica) are equipped with astounding regenerative capabilities that far surpass those of humans. STARGET 1 I 12 7 8 STARGET 1 I 12 Straumann® regenerative SyStem The Insertion of Implants Requires Healthy Bone Tissue Great advances in regeneration have been achieved in dentistry over that last 20 years. We can now regenerate the bone tissue of the jaw, opening the door for implants as a treatment for replacing teeth. This has required scientific evidence documenting the physiological processes involved in tissue formation and the necessary aids for controlling these processes. Today, for example, we know that lost or missing bone can only be regenerated by the body when the bone-forming cells can perform their work undisturbed. Without external intervention, this process would have to compete with the rapid natural wound repair mechanism, which would result in the growth of new connective tissue instead of the desired bone tissue. Fig. 2: The high porosity of Straumann® BoneCeramic™ (90 %) allows blood vessels and vital bone to vascularize into the material. Regeneration Requires Matrices and Membranes Today, one means of guiding the regeneration process requires two aids: a matrix and a membrane. The matrix keeps the space available for the bone to grow while a membrane serves as a barrier to prevent the connective tissue infiltration of the gingiva. Straumann® regenerative SyStem Various types of these matrices and membranes are used today for regenerative purposes. Some of these “placeholders” remain in the body, integrated into the newly formed bone for the rest of the person’s life. Applying membranes for this purpose is also quite complex and time-consuming. Straumann ® MembraGel ® was developed to deal with the disadvantages of the types of membranes used in the past. The time-consuming cutting and fitting of the membrane is unnecessary since MembraGel is applied in liquid form and polymerizes to form a solid film in less than a minute. The resulting hydrogel is biocompatible and completely biodegradable. Periodontitis – The Greatest Threat to the Periodontium For implantology, the regeneration of the periodontium is equally as important as the new formation of bone, which is destroyed by periodontitis and can ultimately result in the loss of the tooth. Despite numerous attempts to regenerate the destroyed tissue, a breakthrough to achieve complete tissue reformation remains to be seen. Straumann ® Emdogain™ can be used in cases to undo some of this destruction, making it possible to prevent loss of the tooth. Emdogain contains the key components required for building up the cementum and periodontal ligament, important parts of the periodontium. These elements, or proteins, tap into the body’s own natural ability to rebuild the surrounding tooth structures, using nature’s help. “Simply Doing More“ – During the Regeneration Process Straumann’s successes in the field of regeneration are promising and we have yet to fully realize our dreams. We are already working on further innovations to guide regenerative processes in an even simpler and more effective manner. We are inspired by two great visions: » A matrix for bone augmentation that breaks down fully and can be used without requiring a membrane. » Guided tissue regeneration that allows for complete preservation of the tooth. Now making its first entrance into the dental market with Straumann MembraGel, we view PEG technology as the foundation for achieving these goals. Beyond MembraGel, there are numerous combinations and degrees of cross-linking these biocompatible hydrogels, which present an exciting range of possible options. This innovative technology is only in the early phases of trials and development and has enormous potential for the future.

Created with PEG (polyethylene glycol) hydrogel technology, Straumann MembraGel is applied in liquid form and molds to the defect. Shortly after application, the liquid components solidify, stabilizing the bone graft and providing an effective barrier to tissue infiltration. Straumann MembraGel then biodegrades over time. It is designed to achieve undisturbed bone regeneration, which is a prerequisite for achieving ideal clinical and esthetic results. “Straumann MembraGel is a key innovation in Guided Bone Regeneration. With the PEG technology we are on the verge of something new, entering a new era in oral tissue regeneration.“ Christoph Hämmerle, University of Zurich Designed for Improving GBR Procedures Straumann MembraGel provides effective support in bone formation for GBR (guided bone regeneration) cases due to its optimized barrier properties. It facilitates undisturbed bone healing as a basis for the optimal clinical outcome achieved by stabilization of the bone graft material. The precise and easy application simplifies the surgical procedure. Straumann® regenerative SyStem Stabilization of the Bone Graft The gel-like consistency of Straumann® MembraGel ® allows for precise application to the surgical site and adaptation to various types and sizes of bone defects. Solidification and Stabilization Once solidified in situ (20 – 50 seconds after application), Straumann® MembraGel is designed to stabilize the underlying bone graft to facilitate undisturbed bone regeneration. Backed by Scientific Documentation Straumann MembraGel is backed by preclinical1,2,3,4,5 and clinical 6 documentation including one- and three-year follow-up data7 presented in 2010 and submitted for publication. The ongoing clinical program with Straumann MembraGel includes over 40 centers and more than 200 patients in Europe and North America. Straumann® MembraGel Exclusive Education Program Straumann® MembraGel was launched in conjunction with a well-received specialized education program that provides in-depth information on pre-clinical and clinical evidence, hands-on product training and the surgical techniques of this new application. Herbert Früh, Head of Business Unit Regenerative at Straumann explained, “MembraGel has allowed Straumann to bring a brilliant idea to STARGET 1 I 12 13 14 STARGET 1 I 12 Straumann® regenerative SyStem fruition. It is an innovative technology that requires training. Customers’ initial experience is that it saves time during intraoral application but it is different to handle. For this reason, it was the right decision to combine the launch of the new product with an intensive education program.” Availability Straumann® MembraGel ® was introduced in Europe and North America toward the end of 2010, with roll-outs to other markets planned in the future.

Biodegradation of different synthetic hydrogels made of polyethylene glycol hydrogel/RGD-peptide Straumann® regenerative SyStem PeG – The TechNOLOGY BehiNd STrAUMANN® MeMbraGel® Straumann MembraGel is a synthetic, biodegradable in situ-formed membrane made of polyethylene glycol (PEG) which forms a molecular network. The material is biocompatible, is applied in liquid form and sets quickly. Due to its gel-like consistency, it can be applied to cover the exact shape of the defect or augmented area and does not require cutting and trimming to shape before application – unlike traditional GBR membranes. What exactly is PEG, and what makes it suited to this purpose? PEG is a polymer (a large molecule comprised of repeating structural units). It is produced through the reaction between ethylene oxide and water or the organic compound ethylene glycol, which is often used as a precursor to polymer materials. PEG is available in a wide range of molecular weights. The molecular weight also determines the consistency of the material, which can vary greatly from waxy-solid to water-soluble liquid states. PEG has a number of properties that are particularly desirable in a number of biological, pharmaceutical and chemical applications: it is highly flexible, non-toxic and non-immunogenic. It is also hydrophilic, meaning that its attachment to biomolecules can increase solubility and decrease aggregation of the molecules. Thanks to these very advantageous properties, PEG has been extensively used in many medical, pharmaceutical and medical device applications. For instance, it is used as a spray-on adhesion barrier and as a main ingredient in laxatives; as an agent for bowel irrigation prior to surgery or colonoscopy; as an addition to protein medications to extend their effect and increase dosing intervals; and as a carrier in various medications, such as soft capsules, ointments, tablets, and lubricants. Preliminary research is also underway to investigate the potential of PEG as a component in many other exciting applications, such as gene therapy, spinal cord injuries and the suppression of carcinogenesis. The use of PEG as a customizable, liquid-applied membrane is therefore another milestone in a long line of applications for this useful, versatile and extensively researched material. modifications: an immunohistochemical study in rats.

What are your thoughts on this educational approach to the launch? I think it’s very important to use an educational approach. What we’re dealing with here is a new technology, a new kind of membrane, a new way to apply the membrane. There are a lot of differences from all the membranes we’ve had before. I think it’s very important to launch the product in a well-structured way so that we know what experience we can rely on. It’s also an opportunity to learn about new things we need to become familiar with before we can use a new technology like this successfully and predictably. “We treated over thirty defects and had minimal complications. Based on this experience and learning, we moved on to larger defects with a very good success rate once again.“ Christoph Hämmerle i know you’re excited about membragel and the progress the product is making. How would you describe your involvement from the start, from inception all the way through the development of the project? It has been very exciting for us. It’s really special to be there when the original idea is born and then to participate in the development of a new product, which is eventually able to solve problems and improve patient care. With all the sharing, teaching, and feedback we’re getting from different people all over the world, being part of this network is something really exciting, something we’ve never done this way before. For this reason, we’re looking forward to continuing with the Straumann® regenerative SyStem STARGET 1 I 12 development of this scientific and educational network and When we conducted our initial study, in which we used a really benefiting from the process.

I think this was need to pass on to our educators? the case because we were careful to use small dehiscence There are three key points. One is that you have to change defects in non-esthetic areas. We treated over thirty defects some of your surgical habits to adapt to the new technology, and had minimal complications. Based on that experience the new way to apply the membrane. The second is to adhere and learning, we began to expand to larger defects, again, to published surgical guidelines. And the third is to begin with with very good success. less complex cases until you have had around ten successful cases, and then move on to more difficult cases. Professor Hämmerle, thank you very much for your time. It’s much appreciated. “I think it’s very important to launch the product in a well-structured way so that we know what experience we can rely on.“ Christoph Hämmerle Returning to the topic of changing habits, this is a new technology, and there is a great temptation to use it in all kinds of different ways because it is rather easy to use and very new and exciting. We need to exercise restraint and really adhere to new practices in aspects of our surgical work. The second point pertains to the surgical guidelines. We have seen that the surgical guidelines are not always followed accurately. Following the surgical guidelines could improve the practical outcomes when it comes to using this new product. The third aspect is the size of the defects we tackle first. 17 18 STARGET 1 I 12 Straumann® regenerative SyStem GrOwTh iN receSSiON An Esthetic Case Selection on Straumann ® Emdogain™ Clinicians have been predictably treating gingival recession with Straumann ® Emdogain™ for years and talking about the beautiful smiles they gave back to their patients – we gave them the chance to prove it.

The implant in position 11 was placed after using the extra-long drill series (Ø 2.2/2.8/3.5 mm) with the 1 mm reduction handle through the Ø 5 mm diameter sleeve (figs. 15, 16). The implant was positioned through the surgical guide. Transmucosal healing caps were positioned and the bone substitute material was inserted into the extraction sockets. Both sites were covered with the resorbable collagen membrane. Final Prostheses and Follow-up After 6 weeks, the OPG showed correct healing with no radiolucencies (fig. 17). Clinically, the implants sounded correct and were stable (fig. 18). The healing abutments were removed and screw-retained transfer parts were placed Fig. 17 Fig. 18 Fig. 19 Fig. 20 Fig. 21 Fig. 22 Fig. 23 Fig. 24 Fig. 25 Straumann® CareS® digital SolutionS in order to take the impression. The three impression copings were splinted with a bridge of acrylic resin that had been prepared a few days before (figs. 21, 22). The three abutments were placed in position (fig. 22) and the metalceramic prosthesis (fig. 24) was cemented with a removable cement (fig. 23). After one month of loading, no complications were registered or stated by the patient. By comparing the values obtained by computer planning with the x-ray taken after implant placement (figs. 19, 20), the precision of the system became visible, with the postextractive implant being about 1 mm deeper than planned and without much variability in the other dimensions. Conclusion The use of computer-guided implant placement allowed expanded treatment options and a fast, minimal invasive surgery for a patient who was not able to withstand long procedures. Producing the guide in such a manner is efficient and it fits well on natural teeth because it has been customized on the patient's impressions. The implant placement in the case reported here demonstrates the reliability of the Straumann ® Guided Surgery system. With software-based treatment planning, the implants could be placed in the same practiced manner as with traditional techniques – but with higher precision and peace of mind. However, the learning curve for software-based planning should not be underestimated; in addition to familiarization with the software, new surgical techniques have to be applied and the surgeon needs to get accustomed to visualizing the surgical procedure through the software.

This can result in poor clinical and esthetic outcomes and time-consuming adjustments during seating. Digitalizing these processes can improve this situation from both a professional and business perspective. From the intra-oral scan to the final restoration Straumann offers a new and complete digital workflow for implant restorations. Starting with an intra-oral scan of the implant site, the customized Straumann® CARES ® Abutment or full contour crown is designed to provide accuracy together with time and cost efficiency through the whole restorative procedure. This kind of digital workflow for implant restorations eliminates cumbersome and time-consuming manual steps in dental practice and in the laboratory. Digital impressions allow immediate quality control by the dentist, and result in an excellent impression being sent to the laboratory. The workflow therefore eliminates or reduces impression retakes and restoration remakes, ensuring that seating appointments are efficient due to the excellent occlusion and contact-points of the restoration.

Over the course of two days, the participants—comprised of clinicians and lab technicians—learned about where the dental world is headed and how interdisciplinary digital dentistry will continue to play a larger part in their practices and labs. The course, cosponsored by Straumann, was designed for the interdisciplinary team (surgeon, restorative dentist and lab technician) to attend and learn about the different digital technologies available to each member of the team, and to understand how each team member and their technology plays a role in achieving optimal patient care and esthetic results. Participants were exposed to all of the links in the digital dentistry chain, including Straumann Guided Surgery Planning Software, the gonyx table, the iTero scanner, and the CS2 scanner. It was a jam-packed two days, filled with lectures, case presentations and hands-on sessions. Participants learned how to treatment plan implant cases with the Straumann Guided Surgery treatment planning software and how a radiographic template and surgical guide can be made with precise accuracy on a gonyx table. They also experienced firsthand how to take an intra-oral impression with an iTero system and how to open an iTero file into the CS2 CADCAM scanner and design a coping, abutment or crown. It was an excellent course, and many of the attendees left excited to start incorporating digital dentistry into their practices. The advice from previous attendees is to register as a team- many who came alone said they wished they had brought their interdisciplinary team members. Baylor will host this course again July 27-28, 2012.

How will the world’s demographics, technologies and economies develop in the future? Will these developments impact implantology, dentistry and the other related medical disciplines? The answers to these questions determine how Straumann designs our products and services, and how we drive innovations. Perhaps the most globally influential trend is the aging population and the attendant need for health services, including restorative dentistry. Practices of the future will look different than those of today. In the Beginning, There Was Titanium In the 1970s, the discovery of titanium’s osseointegrative properties and high compatibility with the human body led to the development of dental implants for the replacement of lost teeth and anchoring of prostheses. Key advantages of implants over conventional denture techniques allowed manufacturers and specialized dentists to develop a new discipline of dentistry, which has since evolved into today’s standard treatments with restorative dentistry. The Excitement Continues Nearly forty years after discovering the osseointegration of titanium, we are entering the next quantum leap in dentistry: the digitalization of restorative dentistry. This will have tangible effects on the way we look at various occupations and, in turn, how dental experts work together. New products and innovations are constantly developed, potentially leading to new treatment opportunities. STARGET interviewed three prestigious dental specialists on trends and new technologies in restorative dentistry: lyndon Cooper, Kenneth malament and daniel Wismeijer.

How will technological changes affect current dentists? Young graduates will want to practice digital dentistry. Mature dentists close to retirement face the choice of investing in new technologies to attract young dentists who will then buy their practices, or continuing the old way and losing some of their original investment. There is no choice in between. If they want to stay in dentistry they will have to invest in new technologies. does digitalization get ample attention in dental education? Students leaving ACTA in a few years will be used to working with intra-oral scanning, cone beam CT scans, digital planning, drill guides, and CADCAM. As they join practices, they will show other dentists the new techniques. We are lucky that our school is new and so are all the fittings.

We will continue to focus our charitable sponsoring on fields related to dentistry, where we feel we have most to offer and where our involvement is appreciated by our stakeholders. Ectodermal dysplasia Ectodermal Dysplasia (ED) refers to a group of genetic disorders characterized by abnormal development of the skin Ectodermal dysplasia patients are typically stigmatized by severely malformed or missing teeth in addition to other debilitating symptoms. and associated structures. Patients typically have few teeth and the teeth they do develop are usually severely malformed. On average, each ED patient in the US faces dental charges of $28,000. This is a considerable burden because more than 50% of patients are not covered by insurance. The NFED, based in Mascoutah, Illinois, is committed to providing help and hope to families around the globe who are affected by this condition. This picture demonstrates the tremendous difference that treatment can make. STARGET 1 I 12 WE CONTINUE OUR TRADITION OF SPONSORING CHARITABLE MISSIONS AND ACTIVITIES THAT BRING BASIC DENTAL CARE AND EDUCATION TO THE UNDERPRIVILEGED. Today, several thousand individuals affected by ED in more than 65 countries receive services from the Foundation, which has provided financial assistance and information, in addition to connecting affected families with each other and with practitioners. Once patients reach adulthood, they can be treated with dental implants, which make a significant difference. Straumann provides free implants to ED patients, but these represent a small portion of the overall treatment costs. We work with the NFED to expand its network of dental professionals who provide free services to ED patients; we also support the foundation with financial aid.
