Endodontically (root canals) treated teeth become mechanically weak and prone to fractures. Especially that occurs, if the volume of the remaining tooth is compromised by decay or large restoration. However, unless already pre-prepared for a crown, endodontically-treated posterior teeth can safely be restored simply with partial-coverage bonded restorations ( onlays, overlays). That approach results in preserving healthy tooth and avoiding extra costs (i.e. post&cores).
On treating anterior (front) teeth, bonded veneers are the treatment of choice, unless tooth structure is already damaged. Most noteworthly, no need for any restoration occurs, if anterior teeth are properly treated and their volume is adequately preserved (conservative obturation of root canals).
From conventional PFM crowns to most sophisticated cad/cam ceramics, all porcelain systems present excellent optical attributes, if there is enough tooth volume. However, when the volume of teeth is moderate, optical integration must be attained with thin restorations. In such cases bonded ceramics demonstrate strong adhesion, mechanical robustness ,and outstanding optical emulation (translucency , opalescence, chroma,hue etc). Even on addressing ultra thin veneers or crowns, E-max (IPS Ivoclar) or zirconia restorations have excellent optical and mechanical properties.
Upon treating large segments of dentition, new occlusion must settle. In such cases, fixed trial restorations (see: temporary restorations – transition to excellence) must be applied for an amount of time. Temporaries are too delivered same-day
