Ultrastructural identification of cells involved in the healing of intramembranous bone grafts in both the presence and absence of demineralised intramembranous bone matrix

Australasian Orthodontic Journal, 2000
Alveolar bone defects are conditions that impede the progress of orthodontic treatment. This study compared the mechanics of the healing of autogenous intramembranous (IM) bone grafts and grafts comprising a mixture of IM and demineralised bone matrix of

Clinical and radiographic evaluation of demineralized bone matrix (grafton) as a bone graft material in the treatment of human periodontal intraosseous defects

Journal of Indian Society of Periodontology, 2013
Purpose: The purpose of this clinical trial was to evaluate the efficacy of demineralized bone matrix (DBM) as a bone graft material in the treatment of human intrabony periodontal defects as compared with control defects treated by open flap debridement

A Modular Bioinstructive Platform Reveals Mechanistic Insights into Additive‐Free, Topography‐Driven Osteogenesis

Advanced Healthcare Materials, EarlyView.
Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...

Camouflaged angiogenic BMP-2 functions exposed by pico-paracrine biohybrids

Frontiers in Bioengineering and Biotechnology, 2023
The constant release of human bone morphogenetic protein 2 (rhBMP-2) in the picomolar range (Pico-Stat) from PDLLA-biohybrids led to the detection of intrinsic novel pro- and anti-angiogenic functions of this cytokine.
