Laminate veneers have become the treatment of choice for restoring tooth esthetics and function conservatively. However, due to their thin nature, the esthetic rehabilitation of discolored teeth following pulp necrosis can be challenging. Translucent zirconia offers a favorable balance between masking ability and optical translucency while maintaining high durability. To enhance the bonding strength between zirconia and adhesive agents, the treatment of the zirconia surface with strong acids has been extensively investigated in laboratory settings. However, the clinical application of this technique has not yet been published.

Restoration of the discolored anterior incisor with an acid-etched translucent zirconia veneer.
The monolithic translucent zirconia veneer successfully restored the discolored anterior tooth. A 2-year follow-up demonstrated that the acid-etched surface ensured the long-term survival of the restoration.
Enhancing bond strength through micromechanical retention created by strong acid etching has proven effective in ensuring a secure bond between the veneer and adhesive cement, contributing to the long-term success of translucent zirconia veneers.
层压贴面已成为保守修复牙齿美观和功能的首选治疗方法。然而,由于其质地薄,牙髓坏死后变色牙齿的美学修复可能具有挑战性。半透明氧化锆在保持高耐久性的同时,在遮盖能力和光学半透明性之间提供了良好的平衡。为了提高氧化锆与粘合剂之间的粘结强度,在实验室环境中已广泛研究了用强酸处理氧化锆表面的方法。然而,该技术的临床应用尚未见报道。
