- Registration Number
- NCT05779345
- Lead Sponsor
- Cairo University
- 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.
- Detailed Description
To overcome anatomical and physiological limitations, different sinus augmentation techniques with immediate or delayed (6-8 months post augmentation) implant placement have been proposed. The most common one is the sinus elevation with a lateral window approach. Although these protocols evoke a high level of success in augmenting the bone quantity (Nkenke E \& Stelzle F, 2009; Schropp et al, 2003) many patients refuse them because of the invasiveness of the augmentative procedure, with obvious prolonged healing times and increased morbidity and costs (Fugazzotto, 2003; Bra¨gger et al, 2004; Toffler, 2004). An alternative therapy for restoring areas of limited bone dimension is the placement of short implants (Wallace SS \& Froum SJ, 2003). ''Standard length implants'' are those of 10 mm in length and have been defined as the minimal length for anticipated success (Griffin TJ \& Cheung WS, 2004).
