BACKGROUND Rhizoma Curculiginis (Xianmao) and Rhizoma Drynariae (Gusuibu) are 'Yang-tonifying' traditional Chinese herbal medicines used to strengthen bones. This investigation aims to assess the systemic effect of extracts of Rhizoma Curculiginis and Rhizoma Drynariae on bone histomorphology and formation, and their local effect on bone healing. METHODS For the investigation of the systemic ...

The ability of a pool of bovine bone morphogenetic proteins bound to synthetic microgranular hydroxyapatite (BMPb-HA) to stimulate bone repair was determined in rat critical size defects. An 8-mm diameter defect was created in the calvaria of 25 rats. In 15 rats, the defects were filled with BMPb-HA homogenized with blood (experimental group), and in 10 rats the defects were filled only with bl...

This systematic review focused on the question, if and to what extent enamel matrix derivative (Emdogain) [EMD]) promotes the regeneration of bone. The influence of combinations with other biomaterials was additionally evaluated. Twenty histomorphometric studies were included in this systematic review. Main results of the reviewed articles were (i) guide tissue regeneration (GTR) of infrabony d...

Objective: Severe craniomaxillofacial injuries and craniomaxillofacial tumors can lead to craniomaxillofacial bone defects and deformities. Seriously affect the patients’ appearance and quality of life. So one-stage repair and reconstruction of craniomaxillofacial bone defects is of great significance. The current study summarizes the clinical experience of one-stage repair and reconstruction o...

PURPOSE Bioactive glass bonds to bone through a calcium phosphate layer that mimics the structure of the mineral phase of bone. Formation of this layer is inhibited in the presence of serum protein. The authors hypothesize that creation of a calcium phosphate layer on the surface of bioactive glass before implantation will enhance bone regeneration and graft material resorption in bone defects....

Repairing large bone defects remains a difficult clinical problem because of the variability in the defects. The traditional methods, such as autograft, allograft bone and biological filler material transplantation are still facing difficulties in clinical application nowadays. Tissue engineering technology has the potential to solve this problem, and it has thus become a popular research topic...

Bone defects in the maxillofacial region vary from a small (few millimeters) periodontal defects to the large segmental defects resulting from trauma or surgical excision of malignancy. Such defects typically have complex three-dimensional structural needs, which are difficult to be restored by biomaterials alone without any osteoinduction (Hanasono, 2014; Sadigh et al., 2016). The use of autog...

Under physiological conditions bone defects often occur at mechanical load bearing sites and bone substitutes used for regeneration should be similarly subjected to mechanical loading stress. In this study, we investigated whether a novel heel-strike like mechanical loading method can be used as a complementary therapy to promote bone regeneration following bone substitute grafting. To test thi...

PURPOSE The aim of this study was to investigate the influence of particle size of autogenous bone grafts on the early stages of bone regeneration. MATERIALS AND METHODS Bicortical skull bone defects were prepared in 15 rabbits (4 in each rabbit). Two defects were filled at random with either small (0.5 to 2 mm3) or large (10 mm3) autogenous bone particles. In addition, 1 defect was left unfi...
