Clinical Management of Cervical Restorations with Closing Gap Technique: A Follow-Up of Two Cases

Background: Cervical restorations remain clinically challenging due to complex anatomy, limited enamel availability, and difficulties in achieving reliable adhesion at dentin or cementum margins. Polymerization shrinkage and marginal leakage are frequent causes of failure. Although the Closing Gap Technique has been proposed to improve marginal adaptation in cervical restorations, evidence supporting its medium- to long-term clinical performance is limited. The aim of this case report was to evaluate the clinical effectiveness of the Closing Gap Technique in the restoration of carious and non-carious cervical lesions. Materials and Methods: Two patients presenting with cervical lesions were treated using the Closing Gap Technique. One case involved carious cervical lesions, while the second included multiple non-carious cervical lesions. Restorations were performed following an enamel-anchored incremental layering protocol with resin composite. Clinical evaluations were conducted at 8 years (case #1) and 2 years (case #2) post-treatment, respectively. Results: Both cases demonstrated favorable clinical outcomes at follow-up. The restorations exhibited good marginal integrity, satisfactory esthetics, absence of marginal discoloration, no secondary caries, and no signs of debonding. The only minor defect observed was slight chipping of one of the restorations. Conclusions: Within the limitations of this case report, the Closing Gap Technique showed stable and predictable medium- and long-term clinical performance, supporting its use as a viable restorative approach for managing cervical lesions in daily clinical practice.
