The rehabilitation of severely worn teeth is a complex challenge for dental practitioners. There are many different types of dental materials and restorative techniques, and there is not a single way to achieve the desired result. This clinical report demonstrates a complete oral rehabilitation with composite resins when using an indirect application and direct techniques, with the support of the Lucia Jig technique, the Willis technique, and diagnostic waxing for the vertical dimension correction. The wide clinical improvement was achieved with the recovery of the function, the esthetics, and the increase of vertical dimension of occlusion through the planned treatment. The proposed treatment maintained the natural teeth, without the intense wear by the application of the composite resins instead of ceramics, together with excellent conditions for the patient to control the posttreatment and extend the durability, with the correct follow-up of appointments. Young patients with extensive dental wear and the loss of vertical dimension should not be directly submitted to ceramic treatments, with preparations for full crowns. Oral rehabilitation using composite resins, either directly or indirectly, allows for the recovery of the function and esthetics, without the intense predictable dental wear, and reduced financial investment.
