Abstract

Objective

To evaluate the precision of complete-arch digital implant scans using intraoral scanning (IOS) and photogrammetry (PG).

Methods

Nineteen completely edentulous arches were included. Each arches contained at least four implants. Abutment-level digital scans were taken using IOS (3Shape Trios 3) and PG (Imetric ICam 4D, 1st gen). Each arch was scanned five times with each device. Implant cartesian coordinates were extracted, and the Spatial Fit, Cross-Arch Distance, and Virtual Sheffield tests were conducted. A generalized estimating equation (GEE) analysis was conducted to compare the precision of IOS and PG for the three tests. A GEE was used to assess further the association between jaw type (maxilla vs. mandible) and the precision for each device in all three tests. The significance level was set at α=0.05.

Results

PG demonstrated greater precision in all three tests (p < 0.0001). Precision was not significantly associated with jaw type in the PG group (p > 0.05). For IOS, the mandibular arch demonstrated inferior levels of precision compared to the maxilla for the Spatial Fit (p = 0.040), Cross-Arch Distance (p = 0.026), and Virtual Sheffield (p = 0.019) tests.

Conclusion

PG represented a more precise scanner for complete-arch digital implant scans. Maxillary arch scans were associated with superior precision compared to scans of the mandible, yet statistical significance was only found in the IOS group.

Clinical significance

IOS scanning for fixed implant rehabilitation of the edentulous jaw with conventional scan bodies should be approached with caution due to the poor precision, particularly in the mandible. PG represented a more precise scanner for complete-arch digital implant scans.

使用摄影测量和口腔内扫描的全弓数字种植体扫描的精度。体内交叉研究。完整弓植入扫描：摄影测量vs IOS。

目的：评价全弓数字种植体口腔内扫描（IOS）和摄影测量（PG）扫描的精度。方法：19个全无牙弓。每个牙弓至少包含四个种植体。使用IOS （3Shape Trios 3）和PG （Imetric ICam 4D，第一代）进行基台级数字扫描。每台设备对每个拱进行了五次扫描。提取种植体笛卡尔坐标，进行空间拟合、十字弓距离和虚拟谢菲尔德测试。采用广义估计方程（GEE）分析比较了三种检测方法的IOS和PG的精度。使用GEE进一步评估颌骨类型（上颌骨与下颌骨）与所有三个测试中每个装置的精度之间的关系。显著性水平设为α=0.05。结果：PG在三种检测中均具有较高的准确性（p0.05）。对于IOS，与上颌骨相比，下颌弓在空间拟合（p=0.040）、跨弓距离（p=0.026）和虚拟谢菲尔德（p=0.019）测试中的精度水平较低。结论：PG是一种更精确的全弓数字种植体扫描扫描仪。与下颌骨扫描相比，上颌弓扫描具有更高的精度，但仅在IOS组中发现有统计学意义。临床意义：常规扫描体的IOS扫描用于无牙颌固定种植体康复，由于精度较差，尤其是下颌骨，应谨慎处理。PG代表了一种更精确的全弓数字植入扫描扫描仪。

期刊介绍： The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research. The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
