The most aggressive diseases that affect the oral environment are considered tumors of the jaw. The surgical treatment is preferably done by surgical resection of the lesion, resulting in a great loss of tissue and esthetics. Multidisciplinary planning is required for the rehabilitation of these cases. Autogenous grafting techniques or vascularized flaps allow ridge reconstruction for implant p...

Experience with 9 patients who underwent mandibular reconstruction with autogenous free bone grafts and subsequent placement of titanium screw-type implants is reported. The interval between bone grafting and implant placement in these patients ranged from 8 to 34 months. A total of 33 implants was placed, followed up for 16 to 53 months, and achieved an 85% survival rate. Analysis of these pat...

Frontal sinus fractures make up about 2-15% of all facial fractures.This is relatively low frequency of occurrence, but it has a large potential of complication and may involve not only the frontal sinuse but more importantly the brain and the eyes. The management depends of the complexity. If anterior wall is fractured with grossly involved nasofrontal duct (NFD) in the injury it is paramount ...

We report the operative technique and results of a new method of central grafting for persistent nonunion of the tibial shaft. The operation is performed through a lateral approach, anterior to the fibula. Fresh autogenous bone from the iliac crest is used to form a central bridge between the tibia and fibula above, below and at the level of the nonunion. In 48 tibiae, most with long-standing n...

The problems of repair and grafting of tendons have received considerable attention. However, conclusions have been hampered by lack of a standard terminology and by attempts to assign the origin oftendon, paratenon, and cicatrix to distinct types ofcell. The potentialities of cells under stress have been insufficiently recognised. Beltzow (1883), Viering (1891), Busse (1892), Rehn (1919) and S...
