Moreover, multiple worldwide gene association studies have shown that individual genetic risk profiles, in respect to inflam- matory high-responder reactions, influence long- term implant success. An adequate individual risk as- sessment should be considered before insertion of titanium devices or application of ceramic implants should be preferred. Dr Jacobi-Gresser showed well-documented clini- cal case reports with immunological, genetic and his- tological findings and summarised: In respect to a spe- cific immune reaction, titanium is—compared to other metals—well tolerated and does not induce allergies. Titanium, however can induce adverse signs of inflam- mation and lead to mucositis, peri-implantitis and peri-implant bone loss due to particle debris, mostly associated with bacterial adhesion. The reason of an individual titanium intolerance is an excessive, genet- ically determined proinflammatory reactivity of mac- rophages to corrosion particles. The microbiological risk is less on zirconia surface because the biofilm adhesion is less compared to titanium. Lasting memories Dr Alessandro Pozzi from Rome, Italy, presented the topic “How to maximise function and aesthetics with a tilted minimally-invasive approach“. The computer- guided implant surgery introduced a min- imally invasive concept in the treatment of partially or totally edentulous patients, with new perspectives based on bone graft-free rehabilitation and low mor- bidity implant surgery. Diagnostic data obtained from CBCT and extra- and intraoral optical surface scan- ning showed a different digital pathway based on facially driven virtual diagnostic waxing, prostheti- cally driven surgical plan, digitally printed surgical template, and prefabricated implant-supported screw-retained interim restorations. The challenging interplay with the surrounding gingival framework supported by tilted implants were emphasised through a step by step clinical protocol to deliver a natural gingival architecture, a direct pink-free pros- thetic emergence profile and learning to differentiate when immediate loading is feasible. Dr Istvan Urban was the highlight of Saturday morning explaining “Vertical and Horizontal Ridge Augmentation”. Dr Urban explained that vertical and horizontal augmentation presents one of the greatest challenges of bone regeneration in implant dentistry. Dr Urban recognised patient selection, patient prepa- ration for surgery, precise surgical techniques, and postoperative management as the key factors in reducing the rate of bone graft complications. The detailed surgical anatomy of the floor of the mouth, the modified lingual flap, as well as the technique for protecting the mental nerve, was presented in detail. Recent research of the “Sausage Technique™” as well as minimally invasive soft tissue reconstruction were presented. Utilising these procedures may reduce the need of harvested autogenous bone and may gener- ally lead to decreased morbidity, and therefore in- creased patient comfort and satisfaction associated with these regenerative procedures and keratinised tissue after ridge augmentation. The participants liked wandering around not only at the welcome reception on Wednesday at sunset on the Hilton Bayfront’s Promenade Plaza. They also enjoyed the reception and celebration of the leaving AAID President. It was easy to hear a wide variety of languages and accents engaged in lively discussions about implants, football, shopping, dining and every- thing else, with remaining memories for all._ contact DGZI Central Office Paulusstraße 1 40237 Düsseldorf, Germany Tel.: 0211 16970-77 sekretariat@dgzi-info.de www.dgzi.de
