The all-metal conventional crown can be used to restore teeth with multiple defective axial surfaces (Fig 6-14). It will provide the maximum retention possible in any given situation, but its use must be restricted to situations where there are no esthetic expectations. This will usually limit it to second molars, some mandibular first molars, and occasionally mandibular second premolars. Because less tooth structure must be removed for its preparation than for crowns with a ceramic component, and because its fabrication is the simplest of any crown, this restoration should remain among those designs considered in planning single-tooth restorations on molars as well as posterior fixed partial dentures.
