dentistry directly from those who are developing the newest techniques and technologies. One of those courses was given by DGZI member and specialist Prof. Dr Suheil Boutros on “Narrow diameter implants for narrow ridges in the aesthetic zone”. In his pre- sentation, Dr Boutros demonstrated the placement of narrow diameter implants (NDI) in a narrow ridge to avoid the need for a large ridge augmentation. In another workshop, Dr Boutros showed that bone management is one of the key elements for achieving success in implant dentistry. Implant site develop- ment at the time of tooth extraction should be con- sidered to prevent bone loss and allow for ideal im- plant placement. The presentation demonstrated how to perform an atraumatic tooth extraction and how to do socket preservation/ridge augmentation. Afterwards, the decision tree in selecting the appro- priate grafting materials was discussed. The second part of the presentation discussed how to success- fully grow bone through Guided Bone Regeneration (GBR) as well as ridge expansion by bone splitting with especially developed chisels and wedges. fied technique using zygomatic implants to manage the severely resorbed maxilla cases were impressively demonstrated. Another topic that was discussed by Prof. Dr Boutros was “Trabecular Metal™ Technology from orthopaedics to dental implantology”. Hereby, he explained the indications for this new mix of two materials. Trabecular Metal™, a porous (80 %) tanta- lum biomaterial with a trabecular like structure for three-dimensional bone in-growth, has been used for more than a decade in orthopaedic surgery. As a result of great success in orthopaedics, a new tapered, threaded titanium dental implant with a trabecular metal midsection has been developed and tested in animal models followed by human cases for over five years. Clinical cases presenting the trabecular metal dental implant for enhanced secondary stability in poor bone quality and its indication in compromised sites in addition to medically compromised patients were presented. Scientific joint lecture Dr Paulo Malo, founder and president of the Malo Clinic, reported about “Recent advancements in graftless solutions, zygomatic, and tilted implants”. In his lecture, he discussed the goals in surgical and prosthetic therapy when using the All-on-4 treat- ment concept to restore the fully-edentulous and failed-dentition patient. The most recent advance- ments of this graftless solution to approach the se- verely resorbed maxilla and mandible were covered. Clinical management of patients were presented by demonstrating data gathering process, diagnosis, treatment planning, surgical protocols, fabrication of both provisional, and definitive implant-retained prostheses. The indications for the use of the modi- Another highlight of the meeting was the scientific joint lecture of Dr Elisabeth Jacobi-Gresser, DGZI spe- cialist with 38 years of experience in oral surgery, im- plantology and environmental medicine, and Prof. Dr Daniel Gustavo Olmedo, specialist and head professor in oral pathology at the University of Buenos Aires, Argentina. The lecture was titled “Risk factors in tita- nium implantology: Reasons to consider zirconia im- plants”. Prof. Dr Olmedo and Dr Jacobi-Gresser stated that over the past 50 years, oral implants fundamen- tally influenced reconstructive concepts in dental medicine. Due to its excellent biocompatibility tita- nium is still the preferred metal not only in dental im- plantology but also in orthopaedic joint replacement.
