ABSTRACT The surface profile roughness (Ra), surface area roughness (Sa), and surface topography of newly developed as-prepared, ground, and polished self-glazed zirconia (SGZ) were evaluated using a profilometer, 3D optical surface profiler, and SEM, with conventional dry-milled zirconia (CZ) as a reference. A statistical analysis was conducted using repeated measures analysis of variance (ANOVA) and the Bonferroni test (α = .05). Results revealed that the material (p = .005), clinical adjustment procedure (p < .001), and interaction between factors (p < .001) had statistically significant effects on the Ra values. SGZ showed lower Sa values than CZ during the same period. Ten patient cases involving the restoration of the monolithic anatomic contour SGZ crowns were investigated. All crowns remained functional until the latest clinical follow-up and no further antagonist wear was observed. Thus, SGZ had relatively lower surface roughness, which was also more easily altered than that of CZ.

自釉氧化锆牙冠的应用潜力通过对搪瓷表面的简单研磨和抛光得到证实

摘要 使用轮廓仪、3D 光学表面轮廓仪和 SEM 评估新开发的制备、研磨和抛光自釉氧化锆 (SGZ) 的表面轮廓粗糙度 (Ra)、表面积粗糙度 (Sa) 和表面形貌，以传统的干磨氧化锆 (CZ) 作为参考。使用重复测量方差分析 (ANOVA) 和 Bonferroni 检验 (α = .05) 进行统计分析。结果显示，材料 (p = .005)、临床调整程序 (p < .001) 和因素之间的相互作用 (p < .001) 对 Ra 值具有统计学显着影响。在同一时期，SGZ 的 Sa 值低于 CZ。研究了 10 个涉及整体解剖轮廓 SGZ 牙冠修复的患者病例。在最近的临床随访之前，所有牙冠都保持功能，并且没有观察到进一步的拮抗剂磨损。因此，SGZ 具有相对较低的表面粗糙度，也比 CZ 更容易改变。
