Abstract

PURPOSE

The effect of core design on the fracture resistance of zirconia-lithium disilicate (LS2) bilayered crowns for anterior teeth is evaluated by comparing with that of metal-ceramic crowns.

MATERIALS AND METHODS

Forty customized titanium abutments for maxillary central incisor were prepared. Each group of 10 units was constructed using the same veneer form of designs A and B, which covered labial surface to approximately one third of the incisal and cervical palatal surface, respectively. LS2 pressed-on-zirconia (POZ) and porcelain-fused-to-metal (PFM) crowns were divided into "POZ_A," "POZ_B," "PFM_A," and "PFM_B" groups, and 6000 thermal cycles (5/55℃) were performed after 24 h storage in distilled water at 37℃. All specimens were prepared using a single type of self-adhesive resin cement. The fracture resistance was measured using a universal testing machine. Failure mode and elemental analyses of the bonding interface were performed. The data were analyzed using Welch's t-test and the Games-Howell exact test.

RESULTS

The PFM_B (1376. 8 ± 93.3 N) group demonstrated significantly higher fracture strength than the PFM_A (915.8 ± 206.3 N) and POZ_B (963.8 ± 316.2 N) groups (<.05). There was no statistically significant difference in fracture resistance between the POZ_A (1184.4 ± 319.6 N) and POZ_B groups (>.05). Regardless of the design differences of the zirconia cores, fractures involving cores occurred in all specimens of the POZ groups.

CONCLUSION

The bilayered anterior POZ crowns showed different fracture resistance and fracture pattern according to the core design compared to PFM.

摘要

目的

通过与金属烤瓷冠对比，评估核设计对前牙氧化锆 - 二硅酸锂（LS2）双层冠抗折性能的影响。

材料与方法

制备40个用于上颌中切牙的定制钛基台。每组10个单位，分别采用设计A和设计B的相同饰面形式构建，设计A和设计B分别覆盖唇面至切端的约三分之一以及腭侧颈缘表面。将LS2压铸氧化锆（POZ）冠和金属烤瓷（PFM）冠分为“POZ_A”、“POZ_B”、“PFM_A”和“PFM_B”组，在37℃蒸馏水中储存24小时后进行6000次热循环（5/55℃）。所有标本均使用单一类型的自粘树脂水门汀制备。使用万能试验机测量抗折性能。对粘结界面进行失效模式和元素分析。数据采用韦尔奇t检验和Games - Howell精确检验进行分析。

结果

PFM_B组（1376.8±93.3 N）的抗折强度显著高于PFM_A组（915.8±206.3 N）和POZ_B组（963.8±316.2 N）（<.05）。POZ_A组（1184.4±319.6 N）和POZ_B组之间的抗折性能无统计学显著差异（>.05）。无论氧化锆核的设计差异如何，POZ组的所有标本均发生涉及核的骨折。

结论

与PFM相比，双层前牙POZ冠根据核设计表现出不同的抗折性能和骨折模式。
