Abstract

Purpose

The purpose of this in vitro study was to evaluate the influence of implant scan body material and its exposed portion on ti-base (titanium-based) positioning accuracy.

Material and Methods

In this study, a total of 14 diagnostic casts were created using two different scan bodies in 7 subgroups, ranging from the bone level to a depth of 6 mm. The diagnostic casts were scanned using a desktop scanner (Ceramill Map 600+, Amann Girrbach, Austria) for reference. The experimental data were scanned five times with an intraoral scanner (TRIOS 5, 3Shape, Copenhagen, Denmark) in each group (n = 70). All scan data were transferred to CAD software (Exocad, DentalCAD 3.1 Rijeka, Darmstadt, Germany). The ti-base positions were determined after the scan body image matching. The ti-base position deviations were analysed in three dimensions. A two-way ANOVA test was used to compare data according to depth and material variables.

Results

The depth factor (p = 0.000) and the interaction between depth and material (p = 0.006) had statistically significant effects on the accuracy of ti-base positioning, whereas the material factor did not show a significant effect (p = 0.559).

Conclusions

As the exposure of the scan bodies decreased, the obtained deviation values tended to increase for both scan body materials.

数字扫描中种植体扫描体材料和暴露对种植体定位精度的影响。

目的：体外研究种植体扫描体材料及其暴露部分对钛基（钛基）定位精度的影响。材料和方法：在本研究中，使用两种不同的扫描体在7个亚组中创建了14个诊断模型，范围从骨水平到6mm深度。诊断铸件使用桌面扫描仪（Ceramill Map 600+, Amann Girrbach, Austria）进行扫描，以供参考。每组用口腔内扫描仪（TRIOS 5, 3Shape, Copenhagen, Denmark）扫描5次实验数据（n = 70）。所有扫描数据传输到CAD软件（Exocad, DentalCAD 3.1 Rijeka, Darmstadt, Germany）。扫描体像匹配后确定反基位置。对反基位置偏差进行了三维分析。采用双因素方差分析（two-way ANOVA）对深度和材料变量进行比较。结果：深度因素（p = 0.000）和深度与材料的交互作用（p = 0.006）对ti-base定位精度有显著的影响，而材料因素无显著影响（p = 0.559）。结论：随着扫描体曝光量的减少，两种扫描体材料得到的偏差值都有增加的趋势。
