Fifteen participants (9 male, 6 female) received a total of 15 monolithic single restorations made from fully sintered (Y, Nb)-TZP (tetragonal zirconia polycrystal) block. The restorations were clinically evaluated for survival, success rate, and periodontal probing depths 6 months after the insertion of the restorations. Esthetic, functional, and biological evaluations were also performed over a 6-month follow-up period. The survival and success rates of the single-unit restorations were 100%. The periodontal probing depth values ranged from 1 to 3 mm. No complications with regard to functional and biological properties were observed after 6 months. The postoperative sensitivity was only a transient phenomenon. The fully sintered (Y, Nb)-TZP single-unit restoration showed highly acceptable quality with successful clinical performance over 6 months.
15名参与者（9名男性，6名女性）共接受了15个由完全烧结的（钇、铌）-四方相氧化锆多晶体（TZP）块体制成的整体单冠修复体。在修复体植入6个月后，对其进行临床评估，包括生存率、成功率和牙周探诊深度。在6个月的随访期内还进行了美学、功能和生物学评估。单单位修复体的生存率和成功率均为100%。牙周探诊深度值在1至3毫米之间。6个月后未观察到功能和生物学特性方面的并发症。术后敏感性只是一种短暂现象。完全烧结的（钇、铌）-TZP单单位修复体显示出高度可接受的质量，在6个月内临床性能良好。
