Bones from calves good for fastening tooth implants
November 05, 2002On Friday, November 8, Mats Hallman, Department of Odontology, Jaw Surgery, Ume'å University in Sweden, will defend a thesis that presents favorable results from implanting bone powder from calves to anchor tooth implants in humans.
Tooth implants have long been a well-tested method to create permanent teeth in toothless sections of the jaw. In certain cases, however, patients have no bone in which to secure the titanium screws. In these cases it is necessary to rebuild the bone prior to the implant operation. This bone has usually been taken from the patients' own hip or jaw, which has required further surgery and caused problems where the bone was taken from. Since many of these patients are elderly, complications have often arisen after the operation. This surgery also entails greater costs.
In a comparative study using three types of implants (bone from the jaw, bone from the jaw combined with bone from calves, and bone only from calves), no differences were noted regarding the development of new bone and the final results from the implant, apart from the fact that the alternative using only calf bone required three months longer to heal.
