This case report illustrates a clinical scenario of a patient with insufficient crowns, gold onlays and localized tooth pain in the posterior teeth, treated with partial and full coverage lithium disilicate restorations.
A female patient presented in the clinics, complaining about tooth pain and unesthetic metal restorations. After a thorough examination, diagnosis and treatment plan, the existing restorations were removed, and a defect-oriented preparation was done to preserve as much as possible of the remaining tooth structure. Final partial and full coverage lithium disilicate restorations were delivered. After a 10-year follow-up no biological complications were observed. Nevertheless, one major chipping was observed in one of the upper molars. This technical complication was resolved with the fabrication of a new ceramic restoration.
Lithium disilicate ceramic posterior full- or partial-coverage restorations are a reliable and predictable treatment option not only for the replacement of tooth structure lost due to caries but also for the replacement of insufficient restorations.
The following key factors are to be considered to pursue long-term success with ceramic restorations: patient selection, minimal invasive tooth preparation, appropriate material selection and cementation. Nevertheless, complications are to be expected, and the patient should be informed accordingly.
本病例报告展示了一名后牙牙冠不足、有金嵌体且局部牙痛患者，采用部分覆盖和全覆盖二硅酸锂修复体进行治疗的临床情况。
一名女性患者前来诊所就诊，主诉牙痛和金属修复体不美观。经过全面检查、诊断和制定治疗方案后，去除了现有的修复体，并进行了以缺损为导向的预备，以尽可能保留剩余的牙齿结构。最终交付了部分覆盖和全覆盖的二硅酸锂修复体。经过10年的随访，未观察到生物并发症。然而，在上颌磨牙中的一颗上观察到一处较大的崩瓷。通过制作新的陶瓷修复体解决了这一技术并发症。
二硅酸锂陶瓷后牙全冠或部分冠修复体不仅是替代因龋齿而丧失的牙齿结构的可靠且可预测的治疗选择，也是替代不足修复体的可靠且可预测的治疗选择。
为使陶瓷修复体获得长期成功，应考虑以下关键因素：患者选择、微创牙齿预备、合适的材料选择和粘结。然而，并发症仍可能出现，应相应地告知患者。
