augmentation of the maxillary sinus is a highly predictable and effective procedure to increase bone volume in the posterior maxilla. Success rates are equal to or better than that of all implants placed in nongrafted maxillary bone in or out of the sinus. Consequently, even in situations where the interocclusal dimension is normal or only moderately increased due to loss of bone height, bone a...

A 60-year-old man with missing maxillary molar teeth received dental implant therapy for reconstruction of occlusion. Sinus floor elevation with autogenous bone graft consisting of iliac bone block and particulate cancellous bone and marrow (PCBM) was performed in the bilateral maxillary sinuses for implant placement. On the right side, bone height in the molar region was less than 2mm. Therefo...

This case demonstrates a rare anomalous of origin of right coronary artery from the left sinus of Valsalva in patients who underwent kidney transplantation complicated by an acute ST elevation myocardial infarction treated with delay angioplasty.

OBJECTIVES The objectives of this systematic review were to assess the survival rate of grafts and implants placed with sinus floor elevation. MATERIAL AND METHODS An electronic search was conducted to identify studies on sinus floor elevation, with a mean follow-up time of at least 1 year after functional loading. RESULTS The search provided 839 titles. Full-text analysis was performed for...

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...

BACKGROUND Sinuslift is meanwhile an established method of bone augmentation in the posterior maxilla. Aim of the study was to evaluate the significance of intraoperative Schneiderian membrane perforations during maxillary sinus floor elevation surgery using autogenous bone harvested from two different donor sites using a Safescraper device on the success rate, graft survival and implant integr...

This work describes a simple technique for the safe removal of the midline parietal bone with the synostotic sagittal suture in infants with sagittal synostosis to avoid dural tearing and bleeding from the superior sagittal sinus. The technique consists of stepwise removal of the midline parietal bone in three pieces instead of one piece, starting with the anterior one-third midline bone being ...

OBJECTIVES The purpose of this study was to evaluate the sinus bone graft resorption over 3 years after two-stage implant placement. MATERIALS AND METHODS The subjects for this study included 30 patients whose maxillary posterior ridges were too atrophic for implants. Bone-added osteotome sinus floor elevation was used in 15 maxillary sinuses, while the bone graft by lateral approach techniqu...

When multiple implants are to be placed, and a pneumatized sinus exists, the published reports suggest that the lateral window approach (LWA) is favored for sinus floor augmentation. Simultaneously, if a transcrestal sinus floor augmentation has been carried out (bone-added osteotome sinus floor elevation), the reports are restricted to single implant placement at any site. The aim of this stud...

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...
