Optimising tooth position with aligners prior to replacing teeth with singleretainer resin-bonded fixed dental prostheses (RBFDPs)

This article describes single-retainer resin-bonded fixed dental prostheses as an excellent minimally invasive alternative to other tooth replacements, and how orthodontic pretreatment with aligners might help to utilise this treatment modality. Two cases are presented in which the required space for the singleretainer resin-bonded fixed dental prostheses was not present initially; but by using a corresponding aligner, pretreatment predictably could be created.
