The goal of this study was to determine the clinical outcome of the lateral sinus floor elevation technique with the repositioning of the bone window. 109 sinus lifts were performed on 102 patients. Following lateral window preparation and lifting of the sinus mucosa, the sinus was grafted with small cerabone® granules. 205 implants were placed (160 simultaneously with grafting; 45 six months after grafting) and the patients were followed up for 12 to 60 months.
The lateral sinus elevation with window repositioning is safe and effective. Repositioned bone windows healed completely. Except of one, all implants remained in function during the whole follow-up period. In 30 cases, biopsies were taken for histomorphometric analysis and graft maturation; these will be published in a second contribution.
