The importance of the superstructure in oral implantology

Long-term success in oral implantology depends on correct timing of temporary splinting, appropriate design and use of the right materials. Because of the differences in the connections between bone and implant and between bone and tooth, movable or rigid joints may be necessary to distribute the forces arising when the implant-tissue junction is stressed. Examples of different designs are given. Galvanic potentials have been shown to arise between metal implants and superstructures. The biological effects of the resulting currents have not been unequivocally determined.
