CATEGORY 78 AUSTRALASIAN DENTIST CLINICAL 2022). Generally, bulk- ll composites can be applied and cured in 4 mm deep layers (Lima et al., 2018). e thermally induced owability of VisCalor bulk (VOCO) allows a packable bulk- ll composite to be applied in the same way as a owable composite, thereby achieving optimal adaptation to cavity oor and walls. Within seconds, as VisCalor bulk cools, it returns to a packable composite, which is easy to shape (Demirel et al., 2021). Bevelled margins were prepared using diamond instruments (Ferraris et al., 2021), thereby achieving biomechanical advantages for the endo-overlay and providing better protection for the underlying tooth structure. Recent nite element analyses (Zheng et al., 2022) show that at butt joint minimally invasive preparations are not as optimal as blunt butt joint preps with 20° bevel. is applies also to the nanoceramic hybrid material Grandio blocs (VOCO). As a result, in order to maintain the integrity of the remaining walls it was possible here to avoid any axial reduction. To facilitate the placement of the endooverlay, a ring-shaped central depression was prepared (visible in Fig. 07b and c as an occlusal box with a depth of only 0.5 mm). As described previously, the endo-overlay was fabricated with an ultrathin thickness of 1 mm (1.5 mm on the supporting cusps) (Valenzuela et al., 2021). It is worth noting that very few occlusal adjustments were required due to the correct design and the precision of the system (Rocca et al., 2021). Conclusion Patient satisfaction e patient was completely satis ed with the aesthetic and functional results of her treatment. u Email: lucasechandia85@gmail.com For the full list of references, contact Australasian Dentist on: gapmagazines@gmail.com Prof. Dr. Lucas Echandia, DDS, is an accomplished prosthodontist and academic based in Córdoba, Argentina.
