title: Maxillary molar sinus floor intrusion at the time of dental extraction.
abstract: After extraction of 20 maxillary molar teeth, inter-radicular bone was intruded onto the sinus floor. Sinus perforation was occluded with oxidized cellulose. After 4 months of healing, implants were placed and later restored successfully. The technique increased vertical dimension about 4 mm on average and allowed placement of longer endosseous implants.
