PURPOSE The aim of this case report is to present the successful clinical treatment of two cases of postoperative infection following maxillary sinus augmentation. METHODS In the two cases of postoperative infection, immediate total removal of the grafted material from the sinus was conducted to stop the spread of the infection, after which a high dose of antibiotics was administrated. Re-aug...

There are different techniques for sinus lifting and augmentation; the factors that contribute to the survival rate of sinus augmentation and dental implant placement are still the subject of discussion. Sinus floor elevation is commonly used in cases where alveolar bone resorption has led to insufficient bone height for the placement of dental implants.

The maxillary sinus augmentation procedure has been gaining more acceptance among dental professionals. The aim of this review article is to provide an update about various aspects of anatomy, physiology, and common pathological conditions of the maxillary sinus and their clinical relevance to the sinus augmentation procedure and subsequent implant placement.

BACKGROUND Maxillary sinus augmentation is one of the most reliable implant site development options to increase vertical bone height. However, graft consolidation requires adequate angiogenesis and migration of cells involved in osteogenesis and bone remodeling. It is speculated that these biologic events are greatly determined by the dimensions of the maxillary sinus cavity. Hence, the purpos...

Pneumatization of maxillary sinus causes insufficient vertical bone volume on posterior maxilla. So the restoration of edentulous posterior maxilla with dental implants is challenging due to a deficient posterior alveolar ridge, unfavorable bone quality and increased pneumatization of the maxillary sinus.1 For maxillary sinus augmentation, the crestal approach and the lateral window approach ha...

PURPOSE The aim of this study was to evaluate the rate of complications in maxillary sinus augmentation surgery and the impact of complications on subsequent implant treatment in a patient population with severe maxillary atrophy scheduled for treatment under general anesthesia. MATERIALS AND METHODS The study population consisted of 70 patients (124 sinuses) with severe maxillary atrophy who...

PURPOSE Implant placement in the posterior maxilla may often be contraindicated because of insufficient bone volume and the presence of the maxillary sinus. In these situations, sinus floor lifting and grafting frequently have been proposed as the best treatment. The aim of this study was to compare histologically the use of 100% autogenous bone versus a combination of autogenous bone and corti...

The purpose of this article is to demonstrate an alternative method for sinus augmentation through a palatal approach when complications do not allow the use of traditional approaches. A 50-year-old male patient presented with multiple previous sinus augmentation attempts. A cone beam computed tomography scan revealed bone graft material had consolidated on the buccal aspect of the lateral sinu...

Two hundred twenty-two sinus augmentation procedures were performed using one of three techniques: crestal approach; lateral approach; or lateral approach with simultaneous implant placement. Forty-one of these sinus augmentation procedures were performed in conjunction with buccolingual ridge augmentation. Of the 222 procedures, 217 (97.7%) were successful. Of 510 implants placed in augmented ...
