The aim of this study was to assess the clinical outcomes and patient satisfaction with monolithic zirconia crowns in patients with severe tooth wear (≥1/3 of the tooth crown) in the aesthetic zone.
The historical prospective study sample consisted of 13 patients previously treated with a total of 84 monolithic zirconia crowns. The patients had been treated in a private clinic in Bergen, Norway, in the period 2012 to 2014. All patients were men, aged 35-67 years (mean age 56.3 years) and had been in need of prosthetic rehabilitation because of severe tooth wear in the aesthetic zone. Technical complications as well as biologic findings were registered when the crowns had been in function one to three years (mean 20 months). The patients completed a self-administered questionnaire regarding satisfaction with aesthetic and function.
No biological complications were registered in 79 of the crowns (94%), and technical complications were registered in only two patients. All patients were satisfied with the aesthetic and function of the monolithic zirconia crowns and would choose the same treatment modality if they were to be treated again.
Within the limitations of this study, we conclude that the rate of clinical complications was low and that the patients were satisfied with the aesthetic as well as the function of the monolithic zirconia crowns.
Monolithic zirconia crowns may provide a valid treatment modality in the aesthetic zone in patients with severe tooth wear.
本研究旨在评估在美学区域内患有严重牙齿磨损（≥1/3 牙冠）的患者中使用整体氧化锆冠的临床效果和患者满意度。
本回顾性前瞻性研究的样本包括了在 2012 年至 2014 年期间在挪威卑尔根的一家私人诊所接受了总共 84 个整体氧化锆冠治疗的 13 名患者。所有患者均为男性，年龄 35-67 岁（平均年龄 56.3 岁），由于美学区域内严重的牙齿磨损，需要进行修复治疗。当牙冠使用 1 至 3 年（平均 20 个月）时，记录了技术并发症和生物学发现。患者完成了一份关于美学和功能满意度的自我管理问卷调查。
79 个牙冠（94%）未记录到生物学并发症，仅在两名患者中记录到技术并发症。所有患者对整体氧化锆牙冠的美学和功能均满意，如果再次接受治疗，他们都会选择相同的治疗方式。
在本研究的限制范围内，我们得出结论，临床并发症的发生率较低，患者对整体氧化锆牙冠的美学和功能均满意。
在严重牙齿磨损的患者的美学区域内，整体氧化锆牙冠可能是一种有效的治疗方式。
