OBJECTIVE Improvements in the bioactivity of zirconia implants for accelerated healing and reduced morbidity have been of continuing interest in the fields of dentistry and orthopedic surgery. The aim of the present study was to examine whether UV treatment increases the osteoconductivity of zirconia-based materials. MATERIALS AND METHODS Smooth and rough zirconia-based disks and cylindrical ...

Osseous grafting represents one mode of therapy to manage periodontal osseous defects. Materials for osseous grafting can be obtained from the same person (autografts), from a different person of the same species (allografts), from a different species (xenografts), or from synthetic materials (alloplasts). The two types of grafts most frequently used in periodontal therapy are autogenous grafts...

A structural bone graft is often required when performing procedures associated with flexible planovalgus deformity correction. These procedures are commonly done in conjunction with a medializing calcaneal osteotomy. Associated procedures include lengthening calcaneal osteotomy through the anterior calcaneus, distraction calcaneocuboid arthrodesis, and plantarflexion osteotomies of the medial ...

In the last years, several methods have been used to enhance bone repair and new bone formation. Numerous researches have been focused on possibilities of healing bone defect by using biomaterial implants. Clay cement may represent an important bone substitute and could be used for the treatment of multiple fractures and after bone tumor resection. The aim of this study is to investigate biocom...

Platelet-rich plasma is a concentrate of growth factors and osteoconductive proteins, which can play a major role in bone biology by accelerating and enhancing bone repair and regeneration. This paper describes the results of using platelet-rich plasma in the management of bisphosphonate-associated necrosis of the jaw. Eight patients with a diagnosis of bisphosphonate-associated necrosis of the...

Calcium phosphate materials are similar to bone in composition and in having bioactive and osteoconductive properties. Calcium phosphate materials in different forms, as cements, composites, and coatings, are used in many medical and dental applications. This paper reviews the applications of these materials in dentistry. It presents a brief history, dental applications, and methods for improvi...

Treatment of delayed union, malunion, and nonunion is a challenge to the orthopaedic surgeons in veterinary and human fields. Apart from restoration of alignment and stable fixation, in many cases adjunctive measures such as bone-grafting or use of bone-graft substitutes are of paramount importance. Bone-graft materials usually have one or more components: an osteoconductive matrix, which acts ...

The need for bone graft materials to fill bony voids or gaps that are not related to the intrinsic stability of the bone that arise due to trauma, tumors or osteolysis remains a clinically relevant and significant issue. The in vivo response of collagen-tricalcium phosphate bone graft substitutes was evaluated in a critical size cancellous defect model in skeletally mature rabbits. While the ma...

Background/Aim. Hydroxyapatite (HAp) is one of the most commonly used calcium phosphate bioceramics with osteoconductive properties. Growth factors are capable directly inducing morphological and functional differentiation neodontoblasts. The aim this study was to investigate effectiveness HAp-based biomaterial in combination transforming growth factor-?1 (TGF-?1) creation new dentine obturatio...
