摘要： 目的: 本研究旨在评估拟种植区垂直黏膜厚度的数字化测量方法的准确性,并探讨垂直黏膜厚度与相应皮质骨厚度之间的相关性。方法: 本研究选取了2020年1月至2023年6月接受数字化牙支持式导板种植手术的48例患者,所有患者完成锥形束CT(cone beam computed tomography,CBCT)数据及3Shape口扫数据的采集,在3Shape Implant Studio软件完成拟合后测量拟种植区垂直黏膜厚度及相应皮质骨厚度(记为数字化技术测量法)。手术中采用改良的牙周探针嵌合于数字化导板导环内测量垂直黏膜厚度(记为改良牙龈穿刺法)。通过配对t检验和Bland-Altman分析评估两种方法测量拟种植区垂直黏膜厚度的差异性和一致性,采用Pearson相关系数分析垂直黏膜厚度与皮质骨厚度的相关性。结果: 数字化技术和改良牙龈穿刺法在测量拟种植区垂直黏膜厚度方面无明显差异(P>0.05),且显示出良好的一致性。垂直黏膜厚度与皮质骨厚度无明显相关性(P>0.05)。结论: 数字化技术是测量拟种植区垂直黏膜厚度的一种准确方法,垂直黏膜厚度与相应皮质骨厚度无明显相关性。

Abstract: Objective: To assess the accuracy of digital measurement of vertical mucosal thickness in the proposed implant area and to investigate the correlation between vertical mucosal thickness and the corresponding cortical bone thickness. Methods: Forty-eight patients who underwent digital tooth-supported guide implant surgery from January 2020 to June 2023 were selected for this study, and all the patients completed the collection of cone beam CT (CBCT) data and 3Shape mouth scan data, and the vertical mucosal thickness of the proposed implantation area was measured after the completion of the fitting in the 3Shape Implant Studio software and the corresponding cortical bone thickness (recorded as digital technometric method). Vertical mucosal thickness was measured intraoperatively using a modified periodontal probe embedded in a digitally guided plate guide ring (recorded as modified gingival puncture method). Differences and consistency between the two measurements of vertical mucosal thickness in the proposed implant area were assessed by paired t-tests and Bland-Altman analyses, and the correlation between vertical mucosal thickness and cortical bone thickness was analysed using the Pearson correlation coefficient. Results: The digital technique and the modified gingival puncture method had not significant difference in measuring vertical mucosal thickness in the proposed implant area (P>0.05) and showed good agreement. There was no significant correlation between vertical mucosal thickness and cortical bone thickness (P>0.05). Conclusion: The digital technique is an accurate method for measuring vertical mucosal thickness in the proposed implant area, and there is no significant correlation between vertical mucosal thickness and the corresponding cortical bone thickness.
