The technique of bonded bridges was introduced in dentistry
by Rochette in 1963. It was the first type of minimally-invasive fixed
prosthesis [1,2]. Its principle consists in bonding a metal frame on
the teeth adjacent to the edentulous area. These bonded bridges
have experienced significant development from their conception
to the present [3,4]. Initially, these restorations failed through
frequent debond caused by the absence of tooth preparation, very
attractive in the early years. In fact, bonding cannot replace the
retention or resistance to occlusal forces (loosening and shear)
provided by the preparations. Nowadays, it is widely accepted
that a minimal preparation of the supporting teeth is essential to
ensure the sustainability of the bonded prosthesis. A careful case
selection is important to predict esthetic and functional restoration
with medium or long-term survival. Abutments should be vital and
aligned showing sufficient enamel available for bonding and should
coronal length which is favorable for retention [5].
