Some studies have demonstrated that in vivo degradation processes are influenced by the material's physico-chemical properties. The present study compares two hydroxyapatites manufactured on an industrial scale, deproteinized at low and high temperatures, and how physico-chemical properties can influence the mineral degradation process of material performance in bone biopsies retrieved six months after maxillary sinus augmentation. Residual biomaterial particles were examined by field scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) to determine the composition and degree of degradation of the bone graft substitute material...

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...
