meetings _ DGZI I (rh-PDGF), which bind to bone substitutes, and BMPs (bone morphogenetic proteins) that improve the resorption of bone substitutes. However, at present, these materials are still very expensive (about⇔5,000pertreatment).Atthemomentthese techniques do not improve long-term success, but they do help in achieving the desired result in less time. _The future: Interdisciplinary cooperation Inhisdiscussionofthe“ClosingtheInterdiscipli- nary Gap”, Prof Dr Paul-Georg Jost-Brinkmann, Berlin, discussed the possibility of preparing ortho- dontic treatment before carrying out implantation. He also highlighted the alternative solution of a transplantation of one’s own teeth. ProfPalmtalkedaboutthelatestdevelopmentsin the GBR technique. He specifically addressed the question of whether future augmentations may be superfluous,withaclear“no”.Guidedboneregenera- tion instead of classic bone augmentation may work in some cases, but not in general. In his speech titled “Is the Implant s Length of any Importance?” Dr AchimW.Schmidt,MSc,Munich,consideredwhether short implants are an alternative to direct sinus lift- ing. His conclusion is that short implants function successfullywithsinteredsurfaces,whichfeaturethe necessaryporousness.Heprovedthiswiththeexam- pleofmanycasesfromhisownpractice. Prof Dr Matthias Kern, Kiel, began his discussion with an almost heretical example. He integrated a Marylandbridgeintotheregionoftheanteriorteeth ofa15-year-oldpatient.After19yearsthebridgeis stillinsitu, andthepatientdoes notrequire anyim- plant! Afterwards he pointed out the pros and cons of full ceramic abutments. Esthetics and bio com- patibility are clearly advantageous, but missing long-term experience, higher costs, and the more complicated and thus critical treatment (adhesive fixation of the abutment on a titanium basis with Panavia 21) are of disadvantage. Dr Peter Gehrke, Ludwigshafen, considers indi- viduallymanufacturedabutmentstobeveryattrac- tive. They can be produced centrally and on an in- dustrial scale by applying new digital techniques. “For CAD/CAM generated zirconium oxide mount- ings there are no restrictions on how to shape the momentum to mesial and distal.” In his speech on “Implants and General Medi- cine“, Prof Dr Thomas Weischer, Essen, indicated the limits of implantology in cases of severe or chronic disease, and he explained their current de- velopment.Today,evenHIVpatientscanbetreated withimplants,providedthatcertainconditionsare observed. The conclusion is that in most cases a dental implant restoration can be performed, even in cases of existing general diseases like HIV, os- teoporosis, cancer or diabetes mellitus. It is highly important to keep in contact with the patient s practitioner,oncologistorotherexpertphysicians. At the end of the congress Dr Heinemann and Prof Palm took turns evaluating the various scien- tific contributions made, considering the aspects thatareimportanttopractice—informationwhich is of practical value to the user in optimizing his ownimplantologicalwork.Theresultofthisanaly- sis can be downloaded from DGZI s homepage www.dgzi.de under “Scientific Review” along with additional literature for private review. The scheduled podium program was comple- mented by a number of other events, including a pre-congress workshop on “Periodontology in Practice”, workshops led by corporate sponsors, seminars, a symposium on “Digital Dental Tech- nologies in Implant Prosthetics” for dental techni- cians,andalargedentalexhibitionhouseddirectly in the venue itself, the Maritim Hotel.
