  • Patent number: 4950162
    Abstract: A prefabricated bridge framework for producing tooth-replacement bridges consists of a support bar to bridge over a gap between teeth and connecting elements for placing the support bar on bridge pillars. The bridge framework as a whole is made of a dental alloy and is capable of being adjusted automatically to the length of a gap between teeth by changing the length of the support bar. Reinforcing ribs are provided on the bottom of the support bar. This bridge framework makes superfluous the manual construction of a wax model of a framework and the subsequent casting in metal that have been required up to now. This bridge framework is always made the same qualitatively, and guarantees that the production of tooth-replacement bridges will be considerably simpler and quicker.
