不同嵌体修复材料对后牙大面积缺损椅旁CAD/CAM修复抗折裂强度的影响
Study on the influence of different inlay restoration materials on the flexural strength of chairside CAD/CAM restoration for large area defects of posterior teeth
目的 分析不同嵌体修复材料对后牙大面积缺损椅旁计算机辅助设计(CAD)/计算机辅助制造(CAM)修复抗折裂强度的影响。 方法 选取2023年12月—2024年6月南方医科大学第八附属医院收治的40例后牙大面积缺损患者,均经椅旁CAD/CAM系统制作嵌体修复,按照随机数字表法分为A组(20例,IPS e.max. CAD陶瓷)和B组(20例,3M Lava™ Ultimate树脂纳米陶瓷)。于修复后12个月评估两组的修复效果及牙体折裂、修复体脱落情况。 结果 修复后12个月,A组与B组边缘密合度比较,差异无统计学意义(P 0.05);A组和B组修复后12个月的边缘密合度与粘接后即刻比较,差异均无统计学意义(P 0.05)。B组无折裂率高于A组(P 0.05),B组无变色率低于A组(P 0.05)。随访期间,两组均未发生牙体折裂。A组有2例(10.0%)发生修复体脱落,B组无修复体脱落。 结论 与IPS e.max CAD修复材料相比,3M Lava™ Ultimate修复材料具有较好的抗折裂强度,修复体折裂率更低,而IPS e.max CAD修复材料的颜色匹配度更好,且两者的边缘密合度差异不大。
Objective To analyze the influence of different inlay restoration materials on the flexural strength of chairside computer-aided design/computer-aided manufacturing (CAD/CAM) restoration for large-area defects of posterior teeth. Methods In this study, 40 patients with large posterior tooth defects admitted to the Eighth Affiliated Hospital of Southern Medical University from December 2023 to June 2024 were selected. All of them were restored with inset by chairside CAD/CAM system and divided into group A (n = 20, IPS e.max.CAD ceramic) and group B (n = 20, 3M Lava™ Ultimate resin nano-ceramic) according to the random number table method. The restoration effects, tooth fractures and restoration detachment of the two groups were evaluated 12 months after restoration. Results Twelve months after restoration, there was no statistically significant difference in marginal fit between group A and group B (P 0.05). Additionally, no statistically significant differences were observed in marginal fit between the 12-month post-restoration assessment and the immediate post-bonding baseline within either group A or group B (P 0.05). Significant differences were observed between group A and group B in both the non-fracture rate and the non-discoloration rate: the non-fracture rate was higher in group B than in group A, while the non-discoloration rate was lower in group B than in group A. During the follow-up period, no tooth fractures occurred in either group. Restoration detachment occurred in 2 cases (10.00%) in group A, while no restoration detachment was observed in group B. Conclusion Compared with IPS e.max CAD repair materials, 3M LavaTM Ultimate repair materials have better flexural strength and a lower flexural rate of the repaired body. The color matching degree of IPS e.max CAD repair materials is better. And the edge fit of the two is not much different.
