The fifth volume of the ITI Treatment Guide series presents the materials and techniques associated with sinus augmentation procedures. The volume opens with a review of the current literature and the relevant ITI Consensus Statements derived from the ITI Consensus Conference held in Stuttgart, Germany, in 2008. This is followed by a discussion of the preoperative assessment of the posterior maxilla, including a detailed description of the anatomy and radiologic examination. Different treatment options are then presented, along with guidelines for choosing the appropriate technique based on thorough risk evaluation and the relative complexity of each option. Various procedures are demonstrated with comprehensive patient case studies, and detailed illustrations serve to clarify potential ambiguities in protocol and technique. The text is completed with a section on intraoperative and postoperative complications to avert the most common pitfalls in clinical practice.
