Bone sialoprotein.
The search for a protein nucleator of hydroxyapatite crystal formation has been a focus for the isolation and characterization of the major non-collagenous proteins in bone. Of the proteins characterized to date, bone sialoprotein (BSP) has emerged as the only bona fide candidate for nucleation. BSP is a highly glycosylated and sulphated phosphoprotein that is found almost exclusively in minera...
متن کاملPhotofunctionalized dental implants: a case series in compromised bone.
PURPOSE Ultraviolet (UV) light treatment of titanium, or photofunctionalization, has been shown to enhance its osteoconductivity in animal and in vitro studies, but its clinical performance has yet to be reported. This clinical case series sought to examine the effect of photofunctionalization on implant success, healing time, osseointegration speed, and peri-implant marginal bone level changes...
متن کاملHuman Bone Sialoprotein
A cDNA encoding the human bone sialoprotein was isolated from a X Zap expression library (made from cultured human bone cell poly(A)+ RNA) using radiolabeled rat bone sialoprotein cDNA (Oldberg, A., and Heinegard, D. (1988) J. Biol. Chem. 263, 1943019432) as a probe. A 5’ 1-kilobase EcoRI fragment of the purified 3-kilobase clone was sequenced and found to contain the entire protein-encoding re...
متن کاملBMP-2 immobilized on nanocrystalline diamond-coated titanium screws; demonstration of osteoinductive properties in irradiated bone.
BACKGROUND Irradiation results in impaired bone healing. Thus, osteosynthesis procedures are afflicted with increased failure rates. To improve osseointegration bone morphogenetic protein-2 (BMP-2) immobilized on nanocrystalline diamond (NCD)-coated implant surfaces might be 1 solution. METHODS By 4 weeks after irradiation of pig's mandible with a dose of 60 Gy a fracture was accomplished. Os...
متن کاملBone properties surrounding hydroxyapatite-coated custom osseous integrated dental implants.
Calcium phosphate (hydroxyapatite or HA) coatings have been applied to Custom Osseous Integrated Implants (COIIs) to improve the quality of the bone-implant integration, yet little is known concerning the biomechanical properties of bone surrounding the HA-coated implants in humans over the long term. The purpose of this study was to characterize the mechanical and histomorphometric properties ...
