With the introduction of adhesive technologies, minimally invasive,
tooth-colored, adhesive restorations have replaced conventional
restorations that sacrificed sound tooth structure for extra retention.
Fiber-reinforced composite restorations have gained wide interest due to
the possibility of using directly at the chair-side replacement of
missing teeth. However, the longevity of adhesive restorations depends
mainly on good bonding between restorative materials and tooth
structure, which should be achieved in situ, within minutes. While
bonding to enamel is reliable through micromechanical retention, bonding
to dentin presents challenges due to its more complex collagenous
structure. This chapter will summarize the general concepts on
chair-side bonding of adhesive restorations to enamel and dentin.
