چکیده

AIM The development of oral implant techniques and the demand for the treatment of increasingly complex cases have drawn the attention of researchers and clinicians towards those systems and materials able to promote bone regeneration. The aim of this paper is to evaluate the clinical behavior and in particular the resorption times of the material used as a filler in postextractive alveolus with the intent of preserving the ridge volume, a prerequisite for successive insertion of osteointegrated fixtures. METHODS A group of 12 patients, aged between 30-40 years, have been selected at the Oral Surgery Unit of the San Giovanni Calibita Hospital in Rome. They all required an endosseous implant following the loss of a dental element due to radicular fracture of periodontal pathology. The grafting material used is OsteoBiol Putty, an antigen-free bone paste composed of 80% granulated mix and 20% pure collagen. RESULTS The results emerging from the histological analysis show that 3 months after insertion of this osteoconductive material in the receiving site it can no longer be detected in the samples collected and it has been completely substituted by trabecular bone tissue. CONCLUSIONS The conclusion is drawn that the heterologous material used in this study shows excellent manageability allowing the operator to easily and accurately remove and shape it in the receiving site.

Subchondral Insufficiency Fracture of the Femoral Head Treated with Core Decompression and Bone Void Filler Support

Subchondral insufficiency fracture of the femoral head (SIFFH) is characterized by acute onset hip pain without overt trauma. It appears as a low intensity band with bone marrow edema on T1-weighted MRI. The most common course of treatment is protected weight bearing for a period of several weeks. Total hip arthroplasty (THA) has been commonly used if the patient does not respond to the initial...

Bone substitute in the repair of the post-extraction alveolus.

In recent years there has been increasing interest in the choice of the best material for bone substitutes. Experimental models enable estimation of biological potential, efficacy and safety of a biomaterial before its clinical application. The aim of this study was to evaluate the response of a bone substitute, UNC bone matrix powder (MOeP-UNC), for repairing the post-extraction alveolus in Wi...
