Since the introduction of the technique of in- serting posterior tilted implants at an angle of up to 35° (in relation to the vertical axis) and the cor- respondingprefabricatedabutmentsforthetreat- ment of the edentulous maxilla or mandible, im- plantdentistryhasexperiencedachangeinitspre- viously established, conventional surgical and prosthetic thinking (Maló etal. 2003, 2005, 2006). Withimplantsinsertedinthisunorthodoxmanner, implementation of regenerative measures in the posterior regions of the atrophic and/or partially edentulous maxilla and mandible is avoided, al- lowing immediate loading and restoration. Clinical studies show that the success and sur- vival rate of implants inserted at such an angle are comparabletothoseinsertedataconventionalan- gle(Khatami&Smith2008;Krekmanovetal.2000; Hinze et al. 2010). Further results demonstrated that there was no significant difference in bone loss between implants inserted with a conven- tional axis and those inserted at an angle (regard- less of jaw and/or region; Zampelis et al. 2007; Francetti etal. 2010). This implantation technique was developed for the rehabilitation of an edentulous jaw, but only very little information is available about its appli- cation for rehabilitation of partial edentulism in posterior regions with FPD (Roccuzzo et al. 2009; Cordaro etal. 2009).
