A prospective clinical research study of various graft materials used for the augmentation of human maxillary sinuses is currently in progress at New York University Department of Implant Dentistry. This interim case report describes the healing response after a sinus augmentation procedure using a new mineralized cancellous bone allograft. The results after 9 months of healing demonstrated a v...

This work investigated the autogenous healing of interface bond between hollow natural fiber (HNF) (e.g., sisal fiber) and reactive magnesium cement (RMC). Preloading -reloading test was conducted to single embedded specimens, results suggested that can be improved by over 300% after wetting-air cycles conditioning, hot water conditioning demonstrated greater efficiency compared room temperatur...

Platelet Rich Fibrin (PRF) is a new biological augmentation material which is remarkable with its rich cellular components and growth factors. The aim of this study was to evaluate the effect of PRF on tendon healing in a rat model. PRF and control groups included eight rats. PRF was obtained with centrifuging blood collected from the rats and applied on the tendon repair site in Achilles tendo...

Concrete is a remarkable structural material that has been widely used in the modern age. Nevertheless, natural causes that affect durability and consequently service life of concrete are related with surface damage and cracking of the material. Cracks can influence functionality for liquid retaining structures and can also decrease durability due ingress of water and ions towards steel reinfor...

Bone grafting has increasingly been used in surgical procedures for enhanced bone augmentation. Tooth-derived graft material received considerable attention due to its chemical composition and autogenous source that can improve tissue healing. The main aim of this study was provide a short comprehensive review on the composition, morphological aspects, clinical outcomes using tooth-derived matr...

Introduction: Gold standard for alveolar cleft bone grafting is autogenous bone. Advantage of adding the growth factors to the bone is established, so adding PRF to the autogenous bone may have beneficial effects. Methods:  Platelet-rich plasma admixed with autogenous bone and as a biologic membrane over the bone grafted alveolar cleft was used. Results:  Autogenous bone in all (four cases...

We report a case of a symptomatic unicameral (simple) bone cyst of the lunate in a 42-year- old woman. The lesion was treated with curettage and cancellous autogenous iliac bone grafting. At five years of follow-up the wrist was pain free, there were no limitations of motion, and the radiographs showed complete obliteration of the cavity. To the best of our knowledge, no other unicameral bone c...

Chloride diffusion and penetration, consequently chloride-induced corrosion of reinforcement, are among the most common mechanisms deterioration concrete structures, and, as such, widely deeply investigated well. The benefits using Ultra-High Performance (Fiber-Reinforced) Concrete—UHP(FR)C to extend service life structures in “chloride attack” scenarios have been addressed, mainly focusing on ...

We report the operative technique and results of a new method of central grafting for persistent nonunion of the tibial shaft. The operation is performed through a lateral approach, anterior to the fibula. Fresh autogenous bone from the iliac crest is used to form a central bridge between the tibia and fibula above, below and at the level of the nonunion. In 48 tibiae, most with long-standing n...
