Abstract

Objectives: In-vitro study to investigate the influence of different pre-treatments and surface coatings on the wear of different zirconia and their antagonists.

Method and materials: Zirconia specimens (3-, 4- and 5-mol yttria tetragonal zirconia; n=160/material) were subjected to pre-treatment (sandblasting 50 μm Al2O3 1 bar; 120 μm Al2O3 3 bar; polishing) and surface coating (spray glazing, micro-layering, layering, veneering). References comprised no pre-treatment or coating. Wear tests were performed (50 N, 120,000 cycles). Wear (mean, maximum, antagonist) and arithmetic mean roughness Ra and average roughness depth Rz were determined.

Statistics: ANOVA, Bonferroni, Pearson correlation (α=0.05).

Results: Ra/Rz showed significant (p < .001) differences (Ra: 0.01 ± 0.01 μm to 0.71 ± 0.06 μm, Rz: 0.31 ± 0.09 μm to 4.33 ± 0.44 μm). Two groups could be distinguished by mean and maximum wear with significant (p < .001) differences: I.) glaze sprayed and without coating (mean wear: 9.4 ± 2.6 μm to 57 ± 21.3 μm, max. wear: 24.1 ± 6.9 μm to 125.4 ± 18.2 μm) and II.) All coating procedures (mean wear: 129.2 ± 22.8 μm to 236.5 ± 62.0 μm, max. wear: 188.7 ± 21.4 μm to 444.2 ± 110.6 μm). Antagonist wear (9.2 ± 4.5% to 29.7 ± 5.0%) showed a significant (p < .001) correlation to surface coating, mean and maximum wear, Ra and Rz. Mean wear significantly (p < .001) correlated with surface coating, maximum wear, and antagonist wear.

Conclusion: Under clinical conditions, layering or veneering can lead to increased wear of the restoration, but in return reduce the abrasion of antagonists. Excessively rough surface treatments should be avoided, as they might increase antagonist wear.

表面处理和玻璃陶瓷涂层对不同类型氧化锆及其拮抗剂磨损行为的影响。

目的：体外研究不同预处理和表面涂层对不同氧化锆及其拮抗剂磨损的影响。方法和材料：氧化锆样品(3-、4-和5-mol氧化钇四方氧化锆；n=160/材料)进行预处理(喷砂50 μm Al2O3 1 bar；120 μm Al2O3 3 bar；抛光)和表面涂层（喷釉、微层、分层、贴面）。参考文献不包括预处理或涂层。进行磨损试验（50 N, 120,000次循环）。测定磨损（平均、最大、拮抗）、算术平均粗糙度Ra和平均粗糙度深度Rz。统计学：方差分析，Bonferroni， Pearson相关（α=0.05）。结果：Ra/Rz （Ra: 0.01±0.01 μm ~ 0.71±0.06 μm, Rz: 0.31±0.09 μm ~ 4.33±0.44 μm）差异有统计学意义（p < 0.001）。两组瓷釉的平均磨损量和最大磨损量差异显著（p < 0.001）： 1.釉面喷涂和未涂层（平均磨损量：9.4±2.6 μm至57±21.3 μm，最大值）；磨损范围：24.1±6.9 μm至125.4±18.2 μm)；所有涂层过程（平均磨损：129.2±22.8 μm至236.5±62.0 μm，最大值）。磨损范围：188.7±21.4 μm至444.2±110.6 μm)。拮抗剂磨损（9.2±4.5% ~ 29.7±5.0%）与表面涂层、平均和最大磨损、Ra和Rz呈显著相关（p < 0.001）。平均磨损与表面涂层、最大磨损和拮抗剂磨损显著相关（p < 0.001）。结论：在临床条件下，分层或贴面会增加修复体的磨损，但反过来会减少拮抗剂的磨损。应避免过度粗糙的表面处理，因为它们可能会增加抗菌剂的磨损。
