Bone reacts very differently to changes in the environment relating to implant surgery. Since the advantages and disadvantages of implants have to be set against each other, the functions of implants and the demands made upon them will be considered first. The contact area between the bone and the implant will then be discussed. The contact surfaces and their induction of necrosis are at present in the forefront of our research in the area of biomechanics. The essential issues are: the avoidance of early temporary porosity, the possibilities of providing best conditions for "accelerated" bone healing, the reduction of refracture risks, and the improvement of infection resistance. Considerable opportunities for improvement of the most recent insights into the biology and biomechanics of the contact zones.
A 5-year-old boy presented with diploic epidermoid tumor associated with subperiosteal hematoma caused by minor trauma. The tumor was removed completely together with the hemorrhage. Bleeding from this type of tumor is unusual, but should be considered as an indication for surgical removal.
