BACKGROUND AND AIMS Autogenous onlay bone grafting is a common procedure for alveolar ridge augmentation. It has been suggested that the amount of healed bone after this technique would be significantly less than the initial quantity. The aim of this study was to determine the relationship between the various parameters influencing the outcome of ridge augmentation procedures. MATERIALS AND M...

PURPOSE To develop a rabbit experimental study to test the hypothesis that surgical repair of hypospadias with severe ventral curvatures might be completed in one stage, if a graft, such as buccal mucosa, could be placed over the tunica vaginalis flap used in corporoplasty for ventral lengthening, with the addition of an onlay preputial island. flap to complete the urethroplasty. MATERIALS AN...

OBJECTIVE To review the outcome of bulbar urethroplasty using two stage surgical techniques. MATERIAL AND METHODS Twenty-two of the 35 patients studied corresponded to end-to-end urethroplasty (ATT) and 13 to dorsal onlay graft (DOG) in preputial skin or oral mucosa variants. Clinical outcome was considered a failure when postoperative surgery was needed or the uroflowmetry was less than 15ml...

Acute osteomyelitis developing in a closed fracture is extremely rare. Only twenty six such cases have been reported in literature so far with most cases being associated with immunodeficiency or polytraumaalongwith a potential source of infection though none of them involved the humeral shaft. We report a case of acute osteomyelitis of shaft of humerus in an unpredisposed 50 year old male with...

The purpose of this review was to analyze publications related to augmentation procedures using autologous onlay grafts and to evaluate the survival/success rates of implants placed in the augmented areas. An automated search was made in Medline, of clinical publications from 2002 to 2007, including at least 5 patients and with a minimum follow-up of 6 months. Ten papers were included. These su...

BACKGROUND This review addressed the focused question of what is the predictability of vertical ridge augmentation techniques for patients, who were diagnosed with insufficient alveolar bone volume for the placement of dental implants. MATERIAL AND METHODS A systematic online review of three main databases was performed between 1966 and 1 November 2007. Four groups of vertical bone augmentati...

The iliac crest has become an often used site for autogenous bone graft, because of the easy access it affords. One of the less common complications that can occur after removal is a graft-site hernia. It was first reported in 1945 (see the work by Oldfield, 1945). We report a case of iliac crest bone hernia in a 53-year-old male who was admitted for elective resection of a pseudarthrosis and r...

PURPOSE This review evaluated (1) the success of different surgical techniques for the reconstruction of edentulous deficient alveolar ridges and (2) the survival/success rates of implants placed in the augmented areas. MATERIALS AND METHODS Clinical investigations published in English involving more than 10 consecutively treated patients and mean follow-up of at least 12 months after commenc...

INTRODUCTION The main problems of autogenous bone transplants are their unpredictable atrophy and their loss of structure. One key factor lies in the poor revascularization of simple onlay grafts. The the aim of this study was to evaluate the revascularization processes in autogenous bone grafts from the iliac crest to the alveolar ridge. METHODS In a sheep model, autogenous bone grafts were ...

The aim of this experimental study was to evaluate the use of prefabricated autogenous bone grafts as onlay grafts to the mandible. Excess bone of 10 x 12 x 40 mm was produced inside blocks of pyrolyzed bovine bone under a polylactic membrane coverage on the outside of the mandible in 15 adult Göttingen minipigs. After 5 months, this bone was harvested and transferred to the premolar region of ...
