Dr Mazen Tamimi , Inter- national Representative of DGZI, Scientific chairman and Dr. Rolf Vollmer, 1st Vice President of DGZI and Congress Chairman welcomed more than 30 partici- pants from Egypt and Middle East. They promised an interesting one day scientific program with interna- tional key note speakers and colleagues presenting theirmasterthesisaswell.“Excellenteducationisone ofthemainfocusesofDGZIandissomethingwecon- centrateonforthesakeofourpatients.Inthisway,we can ensure that our professionals benefit from the best education possible without having to turn to fee-charging companies,” was the statement of Dr Tamimi. _Scientific Program on Friday 26th of March 2010 Abstracts KeynoteSpeakers Dr Roland Hille, Germany The way to the esthetical success Implantology in the aes- thetic zone is one of the biggest challenges in den- tistry. An exact analysis of the clinical situation before we start with our treatment gives us confidence in our treatment plan. We must know the problems as well as the outcome before we start with our surgery and we also must have a clear conceptionofthefinalaestheticprostheticsituation. Thepatientcontemplatesonlythecrown,nottheim- plant in the bone. The patient’s desire is to get a per- fect aesthetic restoration which lasts for a long time. Inparticular,weneedsofttissuesupporttoachievea perfect aesthetic result. This lecture provides infor- mation about important points to achieve success in the aesthetic zone, and also shows mistakes one should avoid. Dr Suheil Boutros, USA New Concept in Preparing the Lateral Window in Sinus Lift Surgery Thelateralwindowsinusliftisawell-documented treatment modality used to augment the posterior maxilla when the remaining alveolar bone is 5 mm or less in height. Several methods of preparing the win- dowhavebeenproposedand documented, including the useofdiamondandend-cut- ting burs and more recently theuseofpiezosurgery.Each of these techniques has its limitations; for example, the use of cutting burs presents higher incidences of the Schneideri membrane perfo- ration, where as high as 40% has been documented. More recently the use of piezo surgery has been pre- sented as an effective and safe means in lateral win- dow preparation. The only limitation found with this surgeryisthatifthelateralwallisthick,itmaybecome a time-consuming and less effective technique. The new innovation utilizes a large size side cutting bur, whichis5-7mmindiameter,makingitverysafe,pre- dictable and a fast way to prepare the window. Dr Mazen Tamimi, Jordan Block Grafts as an option of treatment of severely atro- phiedmandibleandmaxilla Several options for treat- ing a severely atrophied mandible with less than 8 mm of bone remaining above the inferior alveolar nerve will be discussed. These include: _Boneblockgraftsofautogeneousoriginorallograft _Distraction Osteogenesis _Nerve trans-positioning; exact technique & videos _How to perform these advanced surgery solutions _Short implants as an alternative.
