[Indirect adhesive bridges in the lateral parts].

On the basis of a case, this study considers which prosthetic device is suitable as a replacement for a first molar. At the request of the patient, the least invasive option was sought. The outcome in this case was that the adhesive bridge with abutment teeth with class-2 restorations might be suitable. Of the 3 types of adhesive bridges (metal-porcelain, fibre-reinforced composite and ceramic), most experience has been acquired with the 3-piece metal-porcelain adhesive bridge. Several studies assessing the clinical behaviour of this type are available. Its lifespan is rather comparable to that of the conventional bridge on crowns, provided strategic preparation is carried out with grooves and supports to promote resistance. If the palatal or lingual surface consists entirely of enamel for bonding, it does not seem to be a problem for the wing of the bridge to be additionally bonded approximally to a composite restoration if present in the abutment tooth.
