Single tooth cantilever bridges with sub-tissue porcelain pontics represent a very viable alternative to implant therapy, offering lower cost, lower morbidity, and the ability to work with transparent tissues, lack of bone volume or height, root convergence, insufficient inter-radicular space, medical contraindications or lack of patient acceptance for implant therapy.
In the photo below, notice the excellent esthetics of this pontic replacing the upper right lateral incisor. Note The lack of greying of the abutment, i.e., the adjacent cuspid.
Note the presence of papillae realistically surrounding the emergence of the tooth from the tissue.
Note the health of the tissue, with evident stippling and lack of inflammation.
Note the esthetic contour of the gingival crest around the pontic, both in its height and lack of tissue discoloration or edema.
Such a result is routinely available when the I -F Bridge is mated to a sub-tissue pontic.
