Rinsing of allograft bone does not improve implant fixation

BACKGROUND AND PURPOSE Impacted morselized allograft bone is a well-established method for reconstructing bone defects at revision surgery. However, the incorporation of bone graft is not always complete, and a substantial volume of fibrous tissue has been found around grafted implants. We hypothesized that rinsing the bone graft may improve graft incorporation by removing the majority of immun...

Does Countersinking Improve Implant Primary Stability in Low Density Bone?

ABSTRACT In order to evaluate the effect of countersinking on dental implants primary stability installed in low density bones, thirty dental implants were installed in the most proximal region of oxen ribs and grouped as follow: Group1: Fifteen implants installed by standard drilling with countersinking, Group2: Fifteen implants installed by standard drilling without countersinking. The gradua...

Local Application of BMP-2 Specific Plasmids in Fibrin Glue does not Promote Implant Fixation

BACKGROUND BMP-2 is known to accelerate fracture healing and might also enhance osseointegration and implant fixation. Application of recombinant BMP-2 has a time-limited effect. Therefore, a gene transfer approach with a steady production of BMP-2 appears to be attractive. The aim of this study was to examine the effect of locally applied BMP-2 plasmids on the bone-implant integration in a non...

Periosteal Augmentation of Allograft Bone and its Effect on Implant Fixation - An Experimental Study on 12 Dogs§

PURPOSE Periosteum provides essential cellular and biological components necessary for fracture healing and bone repair. We hypothesized that augmenting allograft bone by adding fragmented autologous periosteum would improve fixation of grafted implants. METHODS In each of twelve dogs, we implanted two unloaded cylindrical (10 mm x 6 mm) titanium implants into the distal femur. The implants w...
