Spring Cantilever: When and Why – A Clinical Report.

ABSTRACT

A fi xed partial denture is routinely done for the replacement of the missing natural teeth. In the case of anterior missing teeth, conventional cantilever type of fi xed partial denture is more conservative depending upon the case selection. Replacements of anterior teeth are challenging when there is a generalized spacing between the maxillary anterior teeth. Shape and size of the pontic, which replaces the missing teeth has to be in proportion with natural anterior teeth (golden proportion). In such cases, to achieve acceptable esthetics there may be a need to involve more number of teeth by regular fi xed partial denture. Spring cantilever is an ideal solution in these situations. Th e present article covers the case selection, advantages and disadvantages of spring cantilever type of fi xed partial denture.
