As a result of contin- ued research and improve- ment in diagnostic tools and treatment techniques, predictablesuccessisnowarealityfortherehabilita- tionofmanychallengingclinicalsituations.Inrecent years, dentistry has become greatly influenced by aesthetic considerations. The primary reason for this is patients’ demands for natural appearing restora- tions. This has resulted in a massive development in the field of dental implantology over the past 30 years. A new implant abutment made of fiberglass was introduced recently. This new implant abutment option is cost- and time-effective and it meets the patients’ expectations in relation to function and es- thetics as the implant closely resembles the natural tooth color. This presentation aims at evaluating the effectivenessoffiberglassdentalimplantsinrelation to function and esthetics. Dr Nicholas Papadopoulos, MSc Krems University, Cyprus The two stage mandibular ridge split, an alternative bone expansion technique Introduction Cases of narrow mandi- bular ridges (less than 5 mm inmandible)requirehorizontalaugmentationforthe placement of screw-type dental implants. A two stage mandubular ridge splitting to decrease the risk of malfracture during osteotomy and minimize the possibility of loosing crestal bone is presented. Method After corticotomy of a rectangular buccal seg- mentwiththinseparatingdiscandathreeweekheal- ingperiod,themandibularridgewasexpandedandin some advanced cases split buccally, leaving the buc- cal periosteum attached to the lateralized segment. Results With buccal segments expanded with no compli- cations, we can gain on average 2–3 mm of horizon- tal bone width. Discussion Inthemandible,greenstickfractureduringwiden- ing with osteotomes or expanders has not been con- trollable to date because of cortical thickness and strength of the bone; the risk of malfracture in the middle of the thinnest buccal region is high, with the possibility of future bone receding being very high. With this Two Stage Mandibular Ridge Split technique the location of the greenstick fracture is predetermined away from the midfacial crestal area, and the perfusion of the buccal segment re- mains attached and intact. The buccal cortical seg- ment remains a pediculated graft after ridge split- ting and thus the practical benefit is no bone loss crestally. Dr Rouven Bönsel, MSc Krems University, Germany Prerequisites for immedi- ate loading of dental im- plants Modern clinical ap- proachestoloadingofdental implants promise the pa- tients immediately loaded implants.Basedonthisobservation,thisstudywillex- amine whether, considering the processes occurring duringbonehealing,immediatefunctionalloadingof dental implants is possible. Thisstudyevaluatesthepredictabilityofearlyand immediateloadingprotocolsofimplantsintheupper and lower jaw. In this observational study 450 dental implants were loaded early. The implants were in- serted into various regions of the jaw in the maxilla and mandible. The criteria determined was whether the osseointegration had been completed after three months. The success rate in this observational study ranged from 92 % (upper jaw) to 100 % (lower jaw). The clinical applicability of the treatment concept is very favourable, due to the shortening of the treat- ment time. Dr Adel Byadsi, MSc Krems University, Palestine Sinus Lift—New Technique This lecture will show the advantages of a unique us- age of the Piezo technique in fine and precise cutting of the bone, without damaging or causing perforation of the Schneiderian membrane. This technique enables us to reuse the bone and thus negate the need for additional membrane.
