Maxillary sinus lift surgery (MSLS) is considered to be a useful treatment method for patients with atrophic alveolar bone. Choosing a suitable surgical procedure to simultaneously decrease graft absorption and obtain long-term survival of dental implants is still a challenge. In this study, 20 patients received MSLS with graft of bone morphogenetic protein 2 (BMP2)-loaded calcium phosphate. Dental implants were placed simultaneously in 10 patients receiving MSLS (1-stage group), and in 10 patients receiving dental implants with a 3 to 6 months delay (2-stage group)...

Ten patients who underwent sinus lift surgery with simultaneous implant placement using the intrasinusal locking technique were evaluated retrospectively. All patients were scheduled for sinus floor elevation procedures with simultaneous implant placement. Schneiderian membrane perforation occurred during the lifting procedure, and conventional methods failed to repair the perforation. Therefore, an autogenous bone ring was placed at the base of the maxillary sinus and was locked to the alveolar crest with a dental implant...

Upper jaw MRONJ if not correctly treated can lead to serious complication. Upper jaw MRONJ is frequently associated with maxillary sinusitis, the disease can spread to other paranasal sinuses. Combined approach is the most reliable procedure to treat odontogenic sinusitis; although MRONJ associated sinusitis is considered odontogenic there is no report in literature describing combined approach to treat MRONJ-induced sinusitis. Buccal fat pad represents the best reconstructive option to close the bony defect...

The oral rehabilitation of a patient with atrophic maxilla is one of the main challenges in implant-supported rehabilitations. The implant placement in the posterior region of the maxilla is limited by a deficiency of bone quantity and quality, besides the anatomic restriction of the maxillary sinus. The use of zygoma fixtures, anchoraged in the zygomatic bone, is a useful technique to enable the full arch rehabilitation. However, complications related to this procedure bring a lot of difficulty in solving...

INTRODUCTION: One of the most frequently used method for scanning patients with indication for dental implantation in dentistry is cone beam computed tomography. Implantation, CBCT imaging and implant programme are inevitable when planning a successful replacement of lost teeth. CBCT offers exact information about available bone and its density, adjacent tooth roots, the place of mandibular canal and maxillary sinus and adjacent anatomical structure. AIM: The goal of this study is to estimate accuracy of measurements on CBCT images ofpatients who have implants of different producers and determine if there is any statistically significant correlation between four test groups regardless of the alloy of which implants are made...

BACKGROUND: Insertion of an implant in the edentulous posterior maxilla is a challenging procedure because of poor bone quality and increased pneumatization of the maxillary sinus after tooth extraction. To increase the amount of bone, several surgical bone grafting techniques have been used-with considerable morbidity for patients. Osteotome sinus floor elevation (OSFE) is a less invasive technique. The clinical and radiographic outcome of 53 implants placed with this technique without bone graft has been reported previously...

Maxillary sinus floor augmentation is considered to play a critical role in dental implant treatment. Although many complications, such as maxillary sinusitis and infection, are well known, few reports are available on the risk of surgical ciliated cyst following the procedure. Here we report a case of surgical ciliated cyst following maxillary sinus floor augmentation. A 55-year-old Japanese woman was referred to our hospital because of alveolar bone atrophy in the bilateral maxilla. We performed bilateral maxillary sinus floor augmentation by the lateral window technique without covering the window...
