Purpose: Antral pseudocyst is a common benign lesion that exists in the maxillary sinus. Because of this possible complication, controversy remains with respect to sinus floor elevation operations. The purpose of this study was to analyze the antral pseudocyst related to maxillary sinus augmentation. Patients and Methods: The radiographs of 268 patients who visited Chosun University Dental Hospital from 2008 to 2010 and underwent the maxillary bone grafting procedure were examined. Results: Of the 268 patients who underwent the maxillary bone grafting procedure, 5 patients (1.86%) were diagnosed with antral pseudocysts. In all cases, maxillary sinus floor elevation was performed without aspiration, biopsy or extraction of the antral pseudocyst. Conclusion: Antral pseudocysts are not considered a contraindication for maxillary sinus bone grafting procedure.

Following installation of implant #36, guided bone regeneration was performed on a 57-year-old male patient for treatment of abuccal bone defect. The fl ap was elevated three months later, resulting insatisfactory bone regeneration on the buccal side of the implant during the second surgery. Tooth bone graft material, which has excellent osteoconduction and osteoinduction, has been evaluated as an ideal alternative to bone graft material. Further study of this material will be needed.

Several methods for sinus lifting have been developed for implant installation on the maxillary posterior edentulous area with an alveolar bony defect. The major complication for sinus lifting is sinus membrane perforation, and the crestal approach technique has drawbacks that make it impossible to directly ascertain membrane perforation. Lately, the hydraulic pressure technique was developed for prevention of sinus membrane perforation as well as to obtain an ideal shape of the bone graft material. For sinus lifting, this method reveals a lower part of the membrane using a specially designed drill that elevates the membrane using hydraulic pressure. This method enables the operator to elevate the sinus membrane and bone graft regularly. In this study, morphologic analysis was performed with computed tomography to evaluate the peri-implant bony shape after sinus lifting with a sinus lift drill using hydraulic pressure.
