Brief Summary
Implants in the maxillary posterior region are associated with compromised bone in both quantity - notably in vertical dimension- and quality. Along with the fact that the posterior teeth are subjected to higher occlusal forces than the anterior teeth (Marianne Morand \& Tassos Irinakis, 2007). In order to overcome these shortcomings, various procedures have been advocated including open and closed sinus lift (Nkenke E \& Stelzle F, 2009; Schropp et al, 2003). The use of short implants is a valid alternative for these procedures (Wallace SS \& Froum SJ, 2003) sparing the need of applying augmentation techniques with the associated increased time, morbidity and complexity of such procedures.
