摘要

目的研究不同透明度氧化锆粘接在不同牙基材上的力学性能。材料与方法64颗拔除的磨牙分为牙釉质预备组(E)和牙本质预备组(D)。四种氧化锆陶瓷(n = 8): 5Y-TZP (HT), 5和3Y-TZP多层(GT), 3Y-TZP (LT)和4Y-TZP (MT)。粘接后,试样进行热循环(7500次;5°C - 55°C)和咀嚼模拟(120万循环;10 kg),然后使用光学和激光扫描显微镜研究磨损行为。然后加载试样以检测断裂抗力。结果除HT组1例外,其余标本均成活。氧化锆磨损低于3D扫描仪的分辨率,拮抗剂垂直损失在不同材料之间没有显著差异(p > 0.05)。E-LT组的抗骨折性明显高于E-HT组(p = 0.003)。与牙本质结合的材料之间以及不同基质内的材料之间的抗断裂性无显著差异(p > 0.05)。结论3 y - tzp氧化锆和4Y-TZP氧化锆制备的贴面具有良好的体外性能和抗折断性,与牙基板无关。氧化锆陶瓷均表现出良好的耐磨性。临床意义随着牙齿磨损率的增加,微创牙合贴面的应用变得越来越重要。目标是创造既美观又机械耐用的修复体,同时保持它们薄以减少咬合准备,并确保足够的抗骨折性。由4Y-TZP、多层和3Y-TZP氧化锆陶瓷制成的超薄(裂隙处0.3 mm /牙尖处0.6 mm)牙合贴面在咀嚼模拟中存活了相应的5年。所有氧化锆修复体均表现出耐磨性。

Fracture Resistance and Wear Behavior of Ultra-Thin Occlusal Veneers Made From Translucent Zirconia Ceramics Bonded to Different Tooth Substrates

Objective

Investigation of the mechanical properties of occlusal veneers made from zirconia with varying translucency, bonded to different tooth substrates.

Materials and Methods

Sixty-four extracted molars were divided into two groups: preparation within enamel (E) or extending into dentin (D). Veneers were milled from four zirconia ceramics (n = 8): 5Y-TZP (HT), a multilayer of 5 and 3Y-TZP (GT), 3Y-TZP (LT), and 4Y-TZP (MT). After bonding, specimens underwent thermocycling (7500 cycles; 5°C–55°C) and chewing simulation (1,200,000 cycles; 10 kg), followed by investigation of the wear behavior using optical and laser scanning microscopy. Specimens were then loaded to examine fracture resistance.

Results

All specimens except one in the HT group survived artificial aging. Zirconia wear was below the resolution of the 3D scanner, with no significant difference in antagonist vertical loss across materials (p > 0.05). Fracture resistance was significantly higher in E-LT compared with E-HT (p = 0.003). No significant differences (p > 0.05) were observed in fracture resistance between materials bonded to dentin, or between the materials within different substrates.

Conclusions

Veneers made of 3 and 4Y-TZP zirconia showed promising in vitro performance and fracture resistance, regardless of the tooth substrate. All zirconia ceramics exhibited favorable wear behavior.

Clinical Significance

As tooth wear rates increase, the use of minimally invasive occlusal veneers is becoming more important. The goal is to create restorations that are both esthetically pleasing and mechanically durable, while keeping them thin to minimize occlusal preparation and still ensure sufficient fracture resistance. Ultra-thin (0.3 mm in the fissures/0.6 mm at the cusps) occlusal veneers made of 4Y-TZP, multilayer and 3Y-TZP zirconia ceramics survived chewing simulation corresponding 5-years. All zirconia restorations showed wear-resistant behavior.
