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...

Humeral non unions are often painful and unstable Good surgical management is sometimes very difficult. Fixation with plates and screws and bone grafting may fail. The outcome of revision operation may be adversely affected by restricted movement of elbow. In most cases, the patient has been several times operated with resultant scarring and cicatrisation of the surrounding soft tissues. This r...

PURPOSE To evaluate bone healing in the extraction socket of the feline mandibular canine tooth after grafting. METHODS Eighteen adult cats were submitted to unilateral extraction of mandibular canine tooth and divided into three groups. In group 1 (n=6), control, the extraction socket was left empty. In group 2 (n=6), the extraction socket was filled with autogenous cancellous bone from the ...

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...

Restoration of mandible discontinuity defects continues as a challenge for maxillofacial surgeons. Despite the development of algorithms for reconstruction plates fixation and autogenous grafting techniques, complications are still encountered including screw loosening, bone resorption or delayed/incomplete union. The aim of the study was to analyze the possibility of obtaining bone union in th...

Calcaneal osteomyelitis with pseudarthrosis after calcaneal fracture is rare, and its treatment challenging. We describe the use of a free fibular osteocutaneous flap to treat 52-year-old man who presented an operation for closed comminuted fracture. The patient was previously treated multiple surgeries antibiotics 8 months, but he not cured. performed radical bone debridement reconstruction au...

BACKGROUND In this study, the biocompatibility, stability and osteotransductivity of a new cement based on alpha-tricalcium phosphate (alpha-TCP) were investigated in a bone repair model using a rat model. METHODS The potential of alpha-TCP on bone repair was compared to autogenous bone grafting, and unfilled cavities were used as negative control. Surgical cavities were prepared and designat...

BACKGROUND Temporalis fascia has been recommended for hydroxyapatite sphere exposure. The aim of this study was to identify potential risk factors for exposure of porous polyethylene (Medpor) sphere implants and evaluate the use of autogenous temporalis fascia as a patch graft for exposure. METHODS A retrospective review of consecutive cases of porous polyethylene sphere orbital implant expos...

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...

In the surgical treatment of severe diabetic foot infections, substantial soft tissue loss often accompanies partial foot amputations. These sizeable soft tissue defects require extensive care with the goal of expedited closure to inhibit further infection and to provide resilient surfaces capable of withstanding long-term ambulation. Definitive wound closure management in the diabetic populati...
