Implant therapy in the atrophic posterior maxilla becomes challenging in the presence of reduced maxillary bone height. Sinus augmentation can be performed for resolving this condition prior to implant placement. The aim of this article was therefore to evaluate implant survival rates in the grafted sinus taking into account the influence of the implant surface, graft material, and implant plac...

Bone morphogenic proteins (BMP) are members of the family of transforming growth factors. Fifteen different BMP have been identified, all with varying degrees of cellular activity, including cartilageor bone-inductive properties. Two recombinant proteins are available: recombinant human bone morphogenetic protein (rhBMP)-2 and rhBMP-7. These products have been investigated as alternatives to au...

BACKGROUND To date, no studies have been published in which histomorphometric data from a large group of patients comparing various biomaterials for sinus floor augmentation procedures were evaluated. MATERIALS AND METHODS A meta-analysis of the English literature from January 1993 till April 2009 was carried out. Out of 147 titles, according to our criteria, 64 articles were selected for ana...

OBJECTIVE Maxillary sinus floor augmentation has been shown to be the most predictable surgical technique for enhancing the bone volume in the posterior area of the maxilla. The purpose of this study was to analyze the serial slice image segmentation of newly formed bone and bone substitutes after sinus floor elevation using synchrotron radiation X-ray micro-computed tomography (SR-μCT). MATE...

Many materials are used for sinus augmentation procedures. Anorganic bovine bone (Bio-Oss) has been reported to be osteoconductive, and no inflammatory responses have been observed with the use of this biomaterial. One of the main questions pertaining to Bio-Oss concerns its biodegradation and substitution by host bone. Some investigators have observed rapid replacement by host bone, while othe...

AIMS To evaluate the success of the osseointegration of dental implants in patients with severe maxillary atrophy after sinus lift augmentation and onlay graft surgery with autologous bone grafts. DESIGN A descriptive and analytic study of 27 patients with severe maxillary atrophy and partial or total edentulism, after 4 years follow-up. All cases underwent to autologous bone graft sinus lift...

PURPOSE The control of postoperative discomfort may improve the patient's quality of life as well as treatment acceptance. The aim of the present preliminary report was to assess if the use of autologous platelet concentrate during maxillary sinus augmentation may have a favorable impact on pain and other factors related to patient's quality of life in the first week after surgery. MATERIALS ...

Because of the frequent lack of bone in the posterior maxilla, sinus augmentation has become a commonly practiced treatment modality. Many different materials have been used for augmenting the sinus, and the ideal graft is yet to be found. The present article reports the results of sinuses grafted with calcium sulfate in 2 patients. Bone biopsies were harvested 9 months after the augmentation p...
