BACKGROUND: Few studies have been conducted to assess new bone formation using Biogran, a bioactive glass, in maxillary sinus bone augmentation through a prospective and randomized evaluation. Moreover, there are no studies that evaluate cellular behavior by immunohistochemical assessment for osteoblastic and vascular activity during bone repair. PURPOSE: The aim of this study is to compare new bone formation and cellular behavior with Biogran alone, a 1:1 combination of Biogran and autogenous bone graft, and autogenous bone graft alone in human maxillary sinuses...

BACKGROUND: Implant failures are more common when multiple missing posterior teeth need lateral sinus floor elevation owing to inadequate tissue maturation after grafting. Effects of lateral window dimensions on vital bone formation have rarely been compared. PURPOSE: To compare endo-sinus bone formation between two- and solo-window techniques to rehabilitate multiple missing posterior teeth that need substantial augmentation. METHODS AND MATERIALS: Patients with severely atrophic posterior maxilla were randomized to receive lateral sinus floor elevation via solo or two bony windows...

The objective was to test the hypothesis of no difference in long-term (≥5 years) implant treatment outcomes after maxillary sinus floor augmentation (MSFA) with autogenous bone graft compared to a mixture of autogenous bone graft and bone substitutes or bone substitutes alone. A MEDLINE (PubMed), Embase, and Cochrane Library search in combination with a hand-search of relevant journals was conducted. Human studies published in English between January 1, 1990 and October 1, 2016 were included. Nine studies fulfilled the inclusion criteria...

PURPOSE: Many histologic and histomorphometric studies as well as systematic reviews have shown the clinical success of the use of anorganic bovine bone (ABB, Bio-Oss) in maxillary sinus floor augmentation (MSFA). The molecular processes involved in bone healing are, however, still unknown. The aims of this study were to explore gene expression associated with bone remodeling and inflammation in MSFA sites. MATERIALS AND METHODS: The mRNA expression levels of runt related transcription factor 2 (RUNX2), receptor activator of NF-kB ligand (RANKL), osteoprotegerin (OPG), matrix metallopeptidase 9 (MMP-9), tartrate-resistance acid phosphatase (TRAP), and interleukin-1beta (IL-1β), as well as the ratio of RANKL/OPG were compared between alveolar bone of a group after MSFA with ABB and a maxillary posterior edentulous bone group...

Maxillary sinus pneumatization limits implant placement in the edentulous posterior maxilla. Grafted sinus floor augmentation through Schneiderian membrane elevation and space obliteration with autogenous bone grafts, bone substitutes, or a combination of the two has often been used to resolve this problem. More recently, non-grafted sinus floor elevation has been established. This is based on the concept of membrane elevation and support either by tenting technique or using space-maintaining mesh. The aim of this study was to evaluate the predictability of new bone formation after sinus floor elevation using space-maintaining mesh without graft material and to illustrate the difference between the use of bioresorbable and titanium meshes...

BACKGROUND: It is still unclear whether enamel matrix proteins (EMD) as adjunct to bone grafting enhance bone healing. This study compared histomorphometrically maxillary sinus floor augmentation (MSFA) with β-TCP/HA in combination with or without EMD in humans. METHODS: In ten systemically healthy patients needing bilateral MSFA, one side was randomly treated using β-TCP/HA mixed with EMD (BC + EMD) and the other side using only β-TCP/HA (BC). After 6 months, biopsies were harvested from grafted areas during implant installation, being histologically and histomorphometrically analyzed...

PURPOSE: The aim of this study was to determine the effect of recombinant human bone morphogenetic protein-2 (rhBMP-2)-loaded synthetic bone substitute on implants that were simultaneously placed with sinus augmentation in rabbits. METHODS: In this study, a circular access window was prepared in the maxillary sinus of rabbits (n=5) for a bone graft around an implant (Ø 3×6 mm) that was simultaneously placed anterior to the window. Synthetic bone substitute loaded with rhBMP-2 was placed on one side of the sinus to form the experimental group, and saline-soaked synthetic bone substitute was placed on the other side of the sinus to form the control group...

Sinus lift elevation restores bone mass at the maxilla in edentulate patients before the placement of dental implants. It consists of opening the lateral side of the sinus and grafting beta-tricalcium phosphate granules (β-TCP) under the olfactory membrane. Bone biopsies were obtained in five patients after 60 weeks. They were embedded undecalcified in poly(methyl methacrylate) (pMMA); blocks were analyzed by nanocomputed tomography (nanoCT); specific areas were studied by Raman microspectroscopy. Remnants of β-TCP were osseointegrated and covered with mineralized bone; osteoid tissue was also filling the inner porosity...

Background. One of the most problematic regions for endosseous implants is the posterior maxilla, not only having poor bone density, but also lacking adequate vertical height as a result of sinus pneumatization. The purpose of the present study was a radiologic, histological, and histomorphometrical evaluation, in humans, of specimens retrieved from sinuses augmented with decellularized bovine compact particles, after a healing period of 6 months. Methods. Four patients, with atrophic resorbed maxillas, underwent a sinus lift augmentation with decellularized bovine compact bone from bovine femur...

INTRODUCTION: We have recently used highly pure β-TCP (beta-tricalcium phosphate) as the bone grafting material to avoid highly invasive autogenous bone grafting. We evaluated the osseoconduction potential of highly pure β-TCP in sinus augmentation surgery treatment. MATERIALS AND METHODS: The study group comprised 13 patients who underwent maxillary sinus floor augmentation with β-TCP alone. Seven patients underwent sinus augmentation and implant placement simultaneously...

PURPOSE: This human case series presents the clinical and histologic results of five cases of peri-implantitis with subsequent sinus graft infections. Complications may follow maxillary sinus augmentation procedures. It is possible to have an inflammatory reaction, movement of the implant inside the sinus, formation of an insufficient quantity of osseous tissue, and the production of an oroantral fistula. Complications following maxillary subantral augmentation procedures are relatively rare; however, the risks and benefits of any surgery must be carefully evaluated at the onset...
