Do Patients with Osteoporosis Have Higher Risk to Present Reduced Alveolar Ridge Height? An Imaging Analysis

Indian Journal of Dental Research, 2019
Background: Osteoporosis and periodontitis are both diseases that induce bone resorption. The objective of this study was to verify through panoramic radiography analysis whether patients with osteoporosis have a greater risk of periodontal disease ...

Performance of two bone substitutes of novel cotton-like β-TCP/PDLGA and granular β-TCP on bone regeneration in the femoral bone defect of the Beagle dogs

Bone Reports, 2020
This study aimed to clarify whether novel cotton-like composite made of β-tricalcium phosphate (β-TCP) and poly(Dl-lactide-co-glycolide) (PDLGA) has a different effect on in vivo bone regeneration after bone defect than that of granular β-TCP.

Influence of architecture of β-tricalcium phosphate scaffolds on biological performance in repairing segmental bone defects. [PDF]

PLoS ONE, 2012
BACKGROUND: Although three-dimensional (3D) β-tricalcium phosphate (β-TCP) scaffolds serve as promising bone graft substitutes for the segmental bone defect treatment, no consensus has been achieved regarding their optimal 3D architecture.

One Stage Masquelets Technique: Evaluation of Different Forms of Membrane Filling with and without Bone Marrow Mononuclear Cells (BMC) in Large Femoral Bone Defects in Rats

Cells, 2023
The classic two-stage masquelet technique is an effective procedure for the treatment of large bone defects. Our group recently showed that one surgery could be saved by using a decellularized dermis membrane (DCD, Epiflex, DIZG).

Bone transport techniques in posttraumatic bone defects

Orthopaedics & Traumatology: Surgery & Research, 2012
The treatment of posttraumatic diaphyseal bone defects (BD) calls on a number of techniques including bone transport techniques: isolated shortening, compression-distraction at the fracture site, shortening followed by lengthening in a corticotomy distant from the site and segmental bone transport.The multicenter retrospective study combined 38 cases ...
