The regeneration of bone tissue is the main purpose of most therapies in dental medicine. For bone regeneration, calcium phosphate (CaP)-based substitute materials based on natural (allo- and xenografts) and synthetic origins (alloplastic materials) are applied for guiding the regeneration processes. The optimal bone substitute has to act as a substrate for bone ingrowth into a defect, as well ...

OBJECTIVE The goal of this clinical study was to evaluate dental implant survival rates using the concept of a nonfunctional, immediate loading protocol with nonsplinted dental implants in the grafted maxillary sinus during a 52-week period. Random histomorphological and histomorphometric analysis was completed to evaluate the early healing effect of platelet rich plasma (PRP) and 50% autogenou...

A unicameral bone cyst (UBC) may require surgery if its location increases the risk for pathologic fracture, or if it is painful or increasing in size. This case series demonstrates that curettage and grafting with a bone graft substitute alone can result in healing of the UBC. Three children with UBC and pathological fractures were treated with curettage and grafting using bone graft substitut...

This paper presents a case series of furcation involved teeth complicated with endodontic involvement which were treated with periodontal, endodontic and restorative procedures using different bone regenerative materials like; (a) Calcium phosphosilicate bone substitute having bioactive glass 69% mixed with glycerin 19% and poly-ethylene 12% dispensed in a putty form; (b) hydroxyapatite 70% and...

Biological hydroxyapatite, derived from animal bones, is the most widely used bone substitute in orthopedic and dental treatments. Fluorine is the trace element involved in bone remodeling and has been confirmed to promote osteogenesis when administered at the appropriate dose. To take advantage of this knowledge, fluorinated porcine hydroxyapatite (FPHA) incorporating increasing levels of fluo...

Beta-tricalcium phosphate (beta-TCP) combined with recombinant human bone morphogenetic protein-2 (BMP-2) was examined as a substitute for autograft for packing into interbody fusion cages in the canine lumbar spine model. Discectomy and interbody cage fusion were performed at three disc spaces in eight dogs. Examination of microradiographs and histological sections of the lumbar spine at 16 we...

The search for a material to be utilized as dural substitute has been a continuous one for the last six decades. Many materials have been tried, including the different metals, various biological tissues, and plant derivatives. Recently, synthetic products have been utilized as dural substitute. Among these, Vinyon "N" (Teng and Feigin, 1955), Teflon (Teng, unpublished data), and Orlon* (Huerta...

BACKGROUND The different treatment strategies for bone cysts in children are often associated with persistence and high recurrence rates of the lesions. The safety and clinical outcomes of a combined mechanical and biological treatment with elastic intramedullary nailing, artificial bone substitute and autologous platelet rich plasma are evaluated. METHODS From 02/07 to 01/09 we offered all c...
