Claim:
Method for producing a superstructure ( 7 ) provided with artificial teeth ( 8 ), which superstructure is fitted on at least one implant ( 9 , 10 ), which implant is provided in the oral cavity of a person and is adapted to be fixed in the bone of a lower or an upper jaw ( 1 ), and for producing an aligning plate ( 3 ) with at least one aperture ( 4 ) serving as a guide for drilling a hole ( 5 ) in the bone through the aperture ( 4 ) in the aligning plate, in which hole ( 5 ) said implant ( 9 , 10 ) is fixed, comprising the steps of: fixing at least one reference element ( 2 ) in the bone, locating anatomical structures of the jaw ( 1 ) relative to said reference element ( 2 ), providing fixing means on said aligning plate ( 3 ) to fix the aligning plate ( 2 ) relative to said reference element ( 2 ), having fixed the reference element in the bone and located the anatomical structures relative to said reference element ( 2 ), selecting a position for the aperture ( 4 ) in the aligning plate ( 3 ) relative to said fixing means by taking into account the location of the anatomical structures so that critical anatomical structures, including nerve bundles, are not touched during the drilling of the hole ( 5 ) when the aligning plate ( 3 ) is fixed to the reference element ( 2 ) provided in said jaw ( 1 ) and providing said aperture ( 4 ) in the aligning plate ( 3 ) according to the selected position for the aperture ( 4 ).
