Edentulous ridges in the posterior maxilla are often compromised by reduced bone volume. This anatomic condition often limits dental implant placement of 10 mm in length without prior or simultaneous sinus augmentation. The osteotome technique is an alternative and conservative technique for sinus floor augmentation and immediate implant placement in the posterior region of the maxillary jaw. A...

In the atrophic posterior maxilla, placement of longer (at least 10 mm) and wider diameter implants may significantly improve long-term results, but sinus grafting is often necessary to provide sufficient bone volume for implant support. The crestal approach to sinus augmentation requires penetration of the sinus floor with surgical instruments that are often difficult to control; there is a hi...

OBJECTIVE The purpose of this study was to evaluate the histomorphometric result from maxillary sinus augmentation with calcium phosphate nanocrystal-coated bovine bone (Biocera). STUDY DESIGN Maxillary sinus augmentations were performed on 10 patients with the delayed placement of implants. The lateral bony window was created using a piezoelectric saw, and the sinus membrane was elevated to ...

The effect of intracarotid injections of ouabain (25.0 ng) or acetylstrophanthidin (1.56 tig) on feline carotid sinus baroreceptors was evaluated using an isolated perfused carotid sinus preparation. The effects of the drugs on baroreceptor activity were determined by monitoring carotid sinus nerve activity and systemic arterial blood pressure. Administration of either drug to the isolated caro...

Introduction: Maxillary sinus lift combined with implant placement without grafting allows bone formation in the sinus. However, bone volume in severely atrophic maxilla is often insufficient to ensure initial stability of implants. The purpose of this study was to evaluate the outcome of maxillary sinus augmentation by graft-free two-stage sinus lift using titanium bone fixation device and imp...

Endosseous implants are frequently used for prosthetic reconstruction in the edentulous patient. Sufficient volume and density of the alveolar bone for implant integration and load bearing are prerequisites for good clinical outcome. Bone resorption following the extraction of posterior maxillary teeth sometimes results in severe loss of bone in vertical and ⁄ or horizontal dimensions, which ma...

Assessment of the maxillary sinus anatomy before sinus augmentation is important for avoiding surgical complications, because of the close anatomical relationship between the posterior maxillary teeth and the maxillary sinus. The posterior superior alveolar artery (PSAA) is the branch of the maxillary artery that supplies the lateral sinus wall and overlying membrane. We evaluated the location ...

Sinus lift augmentation is a procedure required for the placement of a dental implant, whose success can be limited by the quantity or quality of available bone. To this purpose, the first aim of the current study was to evaluate the ability of autologous periosteum-derived micrografts and Poly(lactic-co-glycolic acid) (PLGA) supplemented with hydroxyl apatite (HA) to induce bone augmentation i...
