Abstract

AIM

This study was to compare the fracture resistance and cyclic fatigue resistance of hand-layered zirconia crowns and computer-aided design (CAD)-on crowns (lithium disilicate with zirconium oxide).

SETTINGS AND DESIGN

Comparative - study design.

MATERIALS AND METHODS

All ceramic crown preparation was done on a mandibular molar ivorine tooth, impression made, and duplicated. Twenty hand-layered zirconia crowns and twenty CAD-on crowns were fabricated using CAD/computer-aided manufacturing (CAD/CAM) technique. All crowns were cemented to their respective dies using resin cement for evaluating fracture resistance and cyclic fatigue resistance using universal testing machine.

STATISTICAL ANALYSIS USED

Independent samples t-test, Mann-Whitney U-test, and Shapiro-Wilk test were used.

RESULTS

The mean fracture resistance of CAD-on crowns (2660.50 ± 501.303 N) was significantly more than that of hand-layered zirconia crowns (1963.60 ± 452.895 N) (independent samples t-test, < 0.023). Cyclic fatigue resistance test results showed that the mean number of cycles before failure for hand-layered zirconia crowns was 175,297 and for CAD-on crowns was 212,097 (Mann-Whitney U-test, < 0.012).

CONCLUSION

CAD-on crowns were found to have significantly higher fracture resistance and cyclic fatigue resistance properties than hand-layered zirconia crowns.

摘要

目的

本研究旨在比较手工分层氧化锆全冠与计算机辅助设计（CAD）全冠（含氧化锆的二硅酸锂）的抗折性和循环疲劳抗性。

设置与设计

对比研究设计。

材料与方法

在一颗下颌磨牙象牙质牙上制备全瓷冠，制取印模并复制。采用CAD/计算机辅助制造（CAD/CAM）技术制作20个手工分层氧化锆全冠和20个CAD全冠。使用树脂粘结剂将所有全冠粘结到各自的代型上，然后使用万能试验机评估抗折性和循环疲劳抗性。

所用统计分析方法

采用独立样本t检验、曼-惠特尼U检验和夏皮罗-威尔克检验。

结果

CAD全冠的平均抗折力（2660.50±501.303 N）显著高于手工分层氧化锆全冠（1963.60±452.895 N）（独立样本t检验，P<0.023）。循环疲劳抗性测试结果显示，手工分层氧化锆全冠失效前的平均循环次数为175297次，CAD全冠为212097次（曼-惠特尼U检验，P<0.012）。

结论

发现CAD全冠比手工分层氧化锆全冠具有显著更高的抗折性和循环疲劳抗性。
