Grandioso Heavy Flow by Voco and nally a 3mm strip of Ribbond polyethylene ber to ensure adhesion, along with a thin layer of high-load microhybrid resin, in this case, Clear l APX by Kuraray (Fig. 7). Subsequently, layers of composite resin, not exceeding 1mm in thickness, were applied to achieve progressive buildup. Once the biobase was established, a minimal biological preparation was performed using diamond burs, and a de nitive impression was taken for the fabrication of the indirect restoration (Fig. 8). In the second phase, under absolute isolation, the indirect restoration was connected to the previously constructed biobase using an adhesive bonding agent, in this case, a heated composite resin, to ensure an extended working time, high mechanical properties, and favorable aesthetics. Excess material was carefully removed, mainly in proximal areas, and after curing, the rubber dam was removed for the nal view of the restoration, evaluating harmony with the periodontal tissue and occlusion (Fig. 9). u
