目的：本系统综述的目的是评估全瓷单冠的5年生存率，并与金瓷冠的生存率进行比较，并描述生物学和技术并发症的发生率。方法：进行了Medline和Dental全球出版物研究系统的电子检索，并辅以手动检索，以识别全陶瓷和金属的前瞻性和回顾性队列研究，平均随访时间至少为3年的陶瓷冠。患者必须在随访访视时接受临床检查。由两名评审员独立评估所识别的研究和数据提取。每年的失败率进行了分析，使用标准和随机效应泊松回归模型，以获得生存proportions.Results的总结估计：搜索提供了3473标题和177摘要。对86篇文章进行了全文分析，得到34篇符合纳入标准的研究。在Meta分析中，全瓷冠的5年生存率估计为93.3%（95%置信区间（CI）：91.1%-95%），金属-陶瓷冠的5年生存率估计为95.6%（95% CI：92.4%-97.5%）。致密烧结氧化铝（Procera（R）技术）冠显示出最高的5年存活率为96.4%，其次是增强玻璃陶瓷冠（Empress（R）技术）和In Ceramcrowns，存活率分别为95.4%和94.5%。玻璃陶瓷冠5年后的存活率明显较低，为87.5%。全瓷冠还根据在口腔中的位置进行分组和分析。所有四种类型的全瓷冠都显示出较低的生存率时，坐在后牙。此外，对于玻璃陶瓷牙冠，（84.4%）和In Ceram-牙冠（90.4%），差异有统计学意义（P= 0.009，P- 0.028）。根据目前的系统综述，全瓷冠用于前牙时，5年生存率与金瓷冠相当。用于后牙时，致密烧结氧化铝冠（94.9%）和强化玻璃陶瓷冠（93.7%）的5年存活率与金属陶瓷冠相似。此外，当用于前磨牙和磨牙时，InCeram冠和玻璃陶瓷冠的存活率预计较低，分别为90.4%和84.4%。
Objectives: The objective of this systematic review was to assess the 5-year survival rates of all-ceramic single crowns and to compare it with the survival rates of metal-ceramic crowns and to describe the incidence of biological and technical complications.Methods: An electronic Medline and Dental Global Publication Research System search complemented by manual searching was conducted to identify prospective and retrospective cohort studies on all-ceramic and metal-ceramic crowns with a mean followup time of at least 3 years. Patients had to have been examined clinically at the follow-up visit. Assessment of the identified studies and data abstraction was performed independently by two reviewers. Annual failure rates were analyzed using standard and random-effects Poisson regression models to obtain summary estimates of survival proportions.Results: The search provided 3473 titles and 177 abstracts. Full-text analysis was performed for 86 articles, resulting in 34 studies that met the inclusion criteria. In meta-analysis, the 5-year survival of all-ceramic crowns was estimated at 93.3% (95% confidence interval (Cl): 91.1%-95%) and 95.6% (95% Cl: 92.4%-97.5%) for metal-ceramic crowns.All-ceramic crowns were also analyzed according to the material utilized. Densely sintered alumina (Procera (R) technique) crowns showed the highest 5-year survival rate of 96.4%, followed by reinforced glass-ceramic crowns (Empress (R) technique) and In Ceramcrowns with survival rates of 95.4% and 94.5%, respectively. A significantly lower survival rate of 87.5% was calculated for glass-ceramic crowns after 5 years.All-ceramic crowns were also grouped and analyzed regarding the position in the mouth. All four types of all-ceramic crowns showed lower survival rates when seated on posterior teeth. Moreover, for glass-ceramic crowns (84.4%) and In Ceram-crowns (90.4%), this difference reached statistical significance (P= 0.009, P- 0.028).Conclusion: Based on the present systematic review, all-ceramic crowns, when used for anterior teeth, showed survival rates at 5 years comparable to those seen for metal-ceramic crowns.When used for posterior teeth, the survival rates at 5 years of densely sintered alumina crowns (94.9%) and reinforced glass-ceramic crowns (93.7%) were similar to those obtained for metal-ceramic crowns. Furthermore, lower survival rates of 90.4% and 84.4% can be expected for InCeram crowns and glass-ceramic crowns when utilized for premolars and molars.
