Abstract

Objective: The aim of this study was to evaluate the influence of cone-beam computed tomography (CBCT) resolution, 3D printing resolution, and drilling depth on drilling accuracy in guided endodontic access.

Methods: Fifty-six printed canines were designed, fabricated, and mounted in maxillary arch models. Preoperative CBCT and 3D surface scan were matched and used to design a surgical guide with different planning parameters: 1) reference (high-resolution CBCT (80 µm) and 3D printing (50 µm), shallow drilling (14 mm)), 2) low-resolution CBCT (120 µm), 3) low-resolution 3D printing (100 µm) and 4) deep drilling (high-resolution CBCT (80 µm) and 3D printing (50 µm), deep drilling (21 mm)). Guided access into the printed canines was performed in a simulated clinical setting. A postoperative CBCT was matched with the planning data in order to determine the angular and linear (total, mesiodistal, buccolingual and depth) deviation between the planned and performed cavities. Mann-Whitney test was used to analyse differences between the reference group and each test group.

Results: Angular, total linear and buccolingual deviations were significantly higher in the low-resolution CBCT group than in the reference group (median: 3.10° and 2.0° (p<0.01), 1.41 mm and 1.06 mm (p<0.05) and 0.77 mm and 0.41 mm (p<0.05), respectively). Depth deviation was significantly higher in the low-resolution 3D printing group than in the reference group (median: 0.90 mm and 0.45 mm (p<0.01), respectively). No other significant differences between the groups were noted (p>0.05).

Conclusion: Higher CBCT resolution resulted in lower angular and total linear deviation during guided endodontic access. Higher 3D printing resolution yielded lower vertical linear deviation. (EEJ-2024-05-086).

锥形束计算机断层扫描分辨率、3D打印分辨率和钻孔深度对引导牙髓治疗钻孔精度的影响:一项体外研究。
目的:探讨锥形束ct (cone-beam computed tomography, CBCT)分辨率、3D打印分辨率和钻孔深度对引导根管通路中钻孔精度的影响。方法:设计、制作56只打印的犬科动物,并将其安装在上颌弓模型上。术前CBCT和3D表面扫描匹配,设计不同规划参数的手术指南:1)参考(高分辨率CBCT(80µm)和3D打印(50µm),浅钻孔(14 mm)), 2)低分辨率CBCT(120µm), 3)低分辨率3D打印(100µm)和4)深钻孔(高分辨率CBCT(80µm)和3D打印(50µm),深钻孔(21 mm))。在模拟临床环境中引导进入打印的犬。术后CBCT与计划数据相匹配,以确定计划和执行的空腔之间的角和线性(总、中远端、颊舌和深度)偏差。采用Mann-Whitney检验分析参照组与各试验组的差异。结果:低分辨率CBCT组的角度、总线性和颊舌偏差明显高于对照组(中位数:3.10°和2.0°,p0.05)。结论:高的CBCT分辨率可以降低引导下根管通路的角度和总线性偏差。更高的3D打印分辨率产生更低的垂直线性偏差。(eej - 2024 - 05 - 086)。
