Purified xenogeneic cartilage matrix components, including proteoglycan subunits, chondroitin 4 sulfate, and chondroitin 6 sulfate, were inoculated into the knee joint of rabbits, and local as well as systemic responses were evaluated. proteoglycan was associated with synovial hyperplasia and infiltrates of eosinophils and lymphocytes and with rising titers of antiproteoglycan antibodies in a t...

AIM Realize the surgery of sinus lifting floor to allow the installation of osseointegrated implants for oral rehabilitation, with the combination of different biomaterials, autogenous bone and lyophilized bovine bone. BACKGROUND Oral rehabilitation using the installation of osseointegrated implants is an alternative surgical approach that results in the satisfactory form, function and esthet...

AIMS Several materials have been introduced as bone grafts, i.e., autografts, allograft, xenografts, and alloplastic grafts, and studies have shown them to produce greater clinical bone defect fill than open flap debridement alone. The aim of this clinical and radiological 6-month study was to compare and evaluate the clinical outcome of deep intraosseous defects following reconstructive surger...

The aim of this retrospective clinical study is to present the clinical experience of using dermis-fat interpositional grafts in the surgical management of temporomandibular joint (TMJ) ankylosis in adult patients. Eleven adult patients who presented with ankylosis of the TMJ were identified and included in the study. All patients underwent a TMJ gap arthroplasty which involved the removal of a...

PURPOSE This study was undertaken to evaluate the effect of hyperbaric oxygen therapy on autogenous free bone grafts transplanted from iliac crest to the mandibles of rabbits. MATERIALS AND METHODS A piece of corticocancellous bone harvested from iliac crest was grafted to a same-size bone defect in the mandibles of 16 Japanese white rabbits. In 8 rabbits, 20 and 10 sessions of hyperbaric oxy...

AIM The aim of this retrospective study was to evaluate morbidity and possible complications in augmentation procedures before implant placement. METHODS Records from 93 consecutive patients with indication for autogenous bone grafting before implant placement, treated at Department of Oral and Maxillofacial Surgery and Implantology of Uberlândia Federal University, in a 7-year period (July 2...

An animal study is presented, evaluating a method of mandibular reconstruction using a poly(D,Llactide) (PDLLA) scaffold. Six goats underwent a continuity resection of the mandibular angle. The defect was bridged with a preshaped PDLLA scaffold, filled with an autogenous particulate bone graft from the anterior iliac crest, and fixed with two preshaped titanium plates. To accelerate bone healin...

Introduction: Anterior corpectomy with instrumentation and fusion is common in the treatment of fractures, tumors, infections, and kyphotic deformities of the thoracic and lumbar spine. Both autogenous (iliac crest, rib or fibula) as well as allogenous strut grafts are utilized in the reconstruction. One of the advantages of autogenous bone is thought to be the endogenous cells and growth facto...
