比较不同类型的全瓷修复体对下颌第一磨牙的预备量和粘接面积的影响。方法 选择我院 2022年5月-2023年5月采集的10颗人离体下颌第一磨牙，通过Micro CT扫描和3D重建，使用3D打印技术 复制成4组样本：研究1组（全瓷冠）、研究2组（邻牙合全瓷嵌体）、研究3组（MOD全瓷嵌体）和对照组 （空白）。对这些样本按照牙体预备标准进行了不同类型的修复体预备。然后使用逆向工程软件Mimics和 Geomagic Studio对修复体预备量（磨切的牙体组织占牙冠硬组织的体积百分比）和粘接面积进行测量和分 析。结果 研究1、2、3组修复体预备量大于对照组，且研究3组＞研究2组＞研究1组（P＜0.05）；研究1、 2、3组粘结面积大于对照组，且研究3组＜研究2组＜研究1组（P ＜0.05）；研究1、2、3组釉质裸露面积大 于对照组，且研究2组和研究3组小于研究1组（P ＜0.05）。结论 下颌第一磨牙全瓷修复体的预备量和粘接 面积与修复体类型密切相关。
To compare the effects of different types of all-ceramic restorations on the preparation amount and bonding area of mandibular first molars. Methods Ten human mandibular first molars collected from May 2022 to May 2023 in our hospital were selected. Through Micro CT scanning and 3D reconstruction, four groups of samples were copied by 3D printing technology: study group 1 (all-ceramic crown), study group 2 (adjacent teeth all-ceramic inlay), study group 3 (MOD all-ceramic inlay) and control group (blank). These samples were prepared for different types of restorations according to the standard of tooth preparation. Then, the reverse engineering software Mimics and Geomagic Studio were used to measure and analyze the preparation of the restoration (the volume percentage of the grinded tooth tissue to the hard tissue of the crown) and the bonding area. Results The preparation amount in study groups 1, 2 and 3 was greater than that in the control group, and study group 3>study group 2>study group 1 (P <0.05). The bonding area of the study groups 1, 2 and 3 was larger than that of the control group, and the study group 3
