The clinical performance of ceramic veneers is influenced by various clinical and material-related factors.
Retrospective evaluation of extensive anterior ceramic veneers in the upper and lower jaw 36 months after placement in a private practice.
Thirty-seven patients (21 female, 16 male) were restored with adhesively luted extensive ceramic veneers made from a heat-pressed ceramic (Cergo, DeguDent, Hanau, Germany). One dentist restored a total of 130 teeth (maxilla N = 76, mandible N = 54). Adhesive cementation was performed with an etch-and-rinse adhesive (Optibond FL, Kerr Hawe, Karlsruhe, Germany) and a dual-curing composite cement.
After 36 months, the survival rate (in situ criteria) according to Kaplan-Meier was 95.1% (95% confidence interval [CI]: 0.88; 1). Reasons for failure were four ceramic fractures and one biological failure in five restored teeth. Of the restorations, 92.8% (95% CI: 0.86;1) were in service without any clinical intervention and rated successful after 36 months. Interventions were necessary in five cases (three recementations, two endodontic treatments). Clinical performance was not influenced by the veneer position (maxillar/mandibular, survival p = 0.3/success p = 0.4). Veneers with more than 50% of exposed dentin demonstrated a significantly increased risk (hazard ratio 10.6, p = 0.026) for a clinical intervention (recementation, endodontic treatment), whereas no effect on the survival rate could be detected (p = 0.17).
After 36 months of clinical service, extensive veneer restorations made of a pressable ceramic showed a comparable survival and success rate in the upper and lower jaw. Large areas of exposed dentin (>50%) were associated with lower success rates.
Mandibular ceramic veneers made using a heat-pressed ceramic offer the same clinical reliability as do veneers on anterior maxillary teeth. Dentin exposure significantly affects the clinical performance of heat-pressed ceramic veneers.
陶瓷贴面的临床性能受多种临床和材料相关因素的影响。
回顾性评估在私人诊所中放置后 36 个月的上颌和下颌广泛陶瓷贴面的临床效果。
37 名患者（21 名女性，16 名男性）接受了热压陶瓷（德国 DeguDent 公司的 Cergo）制作的广泛陶瓷贴面的粘接修复。一名牙医共修复了 130 颗牙齿（上颌 N = 76，下颌 N = 54）。使用自酸蚀粘接剂（Optibond FL，Kerr Hawe，Karlsruhe，德国）和双重固化复合水门汀进行粘接固位。
根据 Kaplan-Meier 生存分析，36 个月时的生存率（原位标准）为 95.1%（95%置信区间[CI]：0.88；1）。失败的原因是五颗修复牙中有四颗陶瓷破裂和一颗发生生物学失败。在 92.8%（95%CI：0.86；1）的修复体中，无需任何临床干预且在 36 个月后被评价为成功。五例（三例重新粘接，两例牙髓治疗）需要进行干预。贴面位置（上颌/下颌）对临床效果无影响（生存概率 p = 0.3/成功概率 p = 0.4）。暴露牙本质超过 50%的贴面显著增加了临床干预（重新粘接、牙髓治疗）的风险（风险比 10.6，p = 0.026），但对生存率无影响（p = 0.17）。
在 36 个月的临床应用后，使用热压陶瓷制作的广泛贴面在上颌和下颌中具有相似的生存率和成功率。暴露牙本质面积较大（>50%）与较低的成功率相关。
使用热压陶瓷制作的下颌陶瓷贴面具有与上颌前牙贴面相同的临床可靠性。牙本质暴露显著影响热压陶瓷贴面的临床效果。
