Abstract
In severe trauma cases, after jaw resection in tumor surgery, and especially in cases of severe atrophy of the maxillary or mandibular alveolar ridge, a direct implant placement using the one-stage approach with ITI implants as described in Chapter 15 is often not possible. Also, the technique of guided bone regeneration discussed in that chapter would not be an efficient method to restore areas of such extended and severe alveolar atrophy. Therefore, a vertical augmentation with bone grafts most frequently obtained from the iliac crest is the method of choice in patients presenting with such conditions (Figures 17.1–17.4). As with guided bone regeneration, two methods regarding timing of implant placement may be differentiated: (1) implant insertion simultaneously with the bone grafts in which instance the implants serve to stabilize the grafts to the basal bone; and (2) stage approach, that is, the bone grafts are stabilized by means of miniplates or screws, which are removed after graft healing at which time the implants are inserted (Figures 17.1 and 17.2).
