Abstract

Introduction: This in-vitro study investigated limitations of intra-oral scanners (IOS) in capturing palatal defects at decreased mouth openings. The trueness and precision of composite 3D-printed models from Cone-Beam Computed Tomography (CBCT) and IOS were measured.

Methods: A partially dentate palatal defect model was scanned with IOS (3M™TrueDefinition) at various simulated mouth openings. Five silicone impressions were poured in gypsum. Scans were taken using 3M™TrueDefinition; Planmeca Planscan®, n=5 each. Model was scanned on two CBCT (PlanmecaProFace®; Accuitomo170®CBCT, n=5 each). Geomagic®Control2014™ was used to create composite-models merging CBCT with IOS. Thirty composite-models were 3D-printed. Trueness and precision were measured. Pearson Correlation Coefficients measured correlation between mouth opening and data capture. Data analysed using Kruskal-Wallis, Wilcoxon rank-sum, and ANOVA. Statistical significance inferred when p⟨0.05.

Results: Mouth openings ⟨20mm, IOS didn't capture information of soft tissue. Increased mouth opening positively correlated with increased data capture(r=0.93, p=0.001). AccuitomoCBCT and TrueDefinition IOS composite-models had the highest (trueness) and [precision](median (IQR) 0.172 mm(0.062-0.426)); [mean [SD] 0.080 mm [0.008]]. Casts had the lowest results (median (IQR) 0.289 mm(0.119-1.565));[mean [SD] 0.338 mm [0.089]](p⟨0.001).

Conclusion: Mouth opening ⟨20mm resulted in insufficient data capture by IOS for clinical applications. Composite digital models showed promising trueness and precision results.

针对腭部缺陷的多模态数字印模。

介绍：这项体外研究调查了口内扫描仪（IOS）在捕捉口腔开口缩小时的腭部缺损方面的局限性。研究测量了锥形束计算机断层扫描（CBCT）和口内扫描仪制作的复合 3D 打印模型的真实度和精确度：方法：使用 IOS（3M™TrueDefinition）在不同的模拟口腔开口处扫描部分牙性腭缺损模型。在石膏中浇注五个硅胶印模。使用 3M™TrueDefinition；Planmeca Planscan® 进行扫描，每种扫描 n=5 个。模型在两台 CBCT（PlanmecaProFace®；Accuitomo170®CBCT，每台 n=5）上扫描。使用 Geomagic®Control2014™ 创建将 CBCT 与 IOS 相结合的复合模型。三维打印了 30 个复合模型。测量了真实度和精确度。皮尔逊相关系数测量了张口与数据采集之间的相关性。数据分析采用 Kruskal-Wallis、Wilcoxon 秩和和方差分析。当 p⟨0.05 时，推断统计显著性：张口量⟨20 毫米时，IOS 无法捕捉到软组织的信息。张口度的增加与数据捕获量的增加呈正相关（r=0.93，p=0.001）。AccuitomoCBCT 和 TrueDefinition IOS 复合模型的（真实度）和[精确度]最高（中位数（IQR）0.172 毫米（0.062-0.426））；[平均值[标度]0.080 毫米[0.008]]。铸模的结果最低（中位数（IQR）0.289 mm（0.119-1.565））；[平均值[标差] 0.338 mm [0.089]]（P⟨0.001）：结论：张口量⟨20 毫米导致 IOS 采集的数据不足以用于临床应用。复合数字模型显示出良好的真实度和精确度结果。
