Aesthetic and Functional Rehabilitation Using the Composite Resin Injection Technique Guided by a Digital Workflow: Clinical Case Report

Abstract

Aesthetic and functional rehabilitation of patients with severe dental wear represents a clinical challenge that demands conservative, predictable, and efficient approaches. This case report describes the treatment of a 60-year-old male patient with generalized wear and loss of vertical dimension who underwent rehabilitation of the maxillary teeth using the composite resin injection technique guided by a digital workflow. Intraoral scanning, digital wax-up planning (EXOCAD), 3D model printing, fabrication of a transparent silicone index (EXACLEAR), and application of the injectable composite resin G-ænial Universal (GC) were performed according to the index. At the end, restorations were adjusted and polished, and the 4-month follow-up showed functional stability, satisfactory marginal adaptation, and a stable aesthetic outcome with no reported symptoms. The advantages of this technique, such as precise control of shape, thickness, and esthetics, reduced clinical time, and preservation of dental structure, are discussed considering recent literature demonstrating comparable performance to indirect alternatives and good color and functional stability. It is concluded that the described approach is a safe and conservative option for aesthetic and functional rehabilitation in cases of severe tooth wear.
