Aesthetic rehabilitation of discoloured maxillary incisors in a patient with a Class III malocclusion: a case report

This case report presents the aesthetic rehabilitation of a 23-year-old female patient with discoloured maxillary central and lateral incisors following trauma and endodontic therapy. The patient exhibited a Class III malocclusion with a reverse overjet. A conservative treatment plan was formulated to preserve tooth structure while improving colour consistency, tooth morphology and overall smile aesthetics. Management included non-vital bleaching using an inside/outside open technique, vital tooth whitening and placement of lithium disilicate veneers from UR2 to UL2. Composite bonding was performed on the upper canines to enhance tooth form. Mock-up driven, minimally invasive preparations were used, with a digital CAD/CAM approach with bonding protocols designed to optimize adhesion and aesthetics. At the 6-month follow-up, restorations remained stable with no evidence of complications. This case illustrates the importance of conservative strategies, precise planning, and patient cooperation in achieving successful aesthetic outcomes for previously treated, discoloured anterior teeth. CPD/Clinical Relevance: A thorough aesthetic assessment and meticulous planning prior to treatment execution are essential.
