[Experimental studies on the stability of the functionally stable supporting structure inplant].
It has been shown clinically that the healing processes encountered at the site of a subperiosteal implant which is implanted as a sustainer for dentures is greatly dependent on the method of fixation. The inflammatory reactions around the abutments are less pronounced and epithelial attachment enhanced if a absolute rigid fixation exists between the implant material and the mandible. In order to study the stability of a scaffolding implant material under different conditions, measurements were undertaken on isolated cadaver mandibles. The dynamic forces acting on the fixed implant in an axial and transversal direction were recorded using a specially designed string gauge. The effects on the static forces of fixation were registered and evaluated. It could be demonstrated that the forces of fixation which were achieved by applying the general principles of compression osteosynthesis surpassed many times the shearing forces encountered at the time of functional stress. Conclusions are drawn regarding a possible improvement of fixation techniques used in such subperiosteal implants.
