摘要

目的

探讨数字化印模技术在多学科联合诊疗中的三维精度，及其对操作者经验差异的临床代偿效应。

方法

构建包含三维均方根误差（

RMSE

)、师生操作耗时差（技能鸿沟，Δ

)及多维主观评价体系，对比医师与初学者在普通正畸/伴牙周病场景及单/双植体种植修复场景下的印模效能。

结果

数字化3D打印模型总体

RMSE

（0.076 9±0.019 5) mm优于传统石膏模型（0.108 8±0.026 4) mm。正畸与伴牙周病组中，师生操作的Δ

分别显著降低55.39%、46.41%；同时种植场景下双植体组操作耗时离散度显著降低。多维主观评价显示，数字组的患者接受度、操作便捷性优于传统组（

0.01），医护人员偏好数字化流程并支持分级授权。

结论

数字化印模三维重建精度更高，其经验代偿效应具有显著的场景特异性。在正畸与牙周病治疗中可提升临床操作稳定性，在复杂种植修复中经验代偿作用较弱。本研究为该技术临床推广、完善多学科诊疗分工与分级授权管理提供实践依据。

Abstract

Objective

To assess the three‑dimensional accuracy and experience‑dependent compensatory effect of digital impressions in multidisciplinary dental treatments.

Methods

An evaluation system including accuracy (Root Mean Square Erro

RMSE

)

expert‑novice operation time difference (skill gap

)

and multidimensional subjective evaluation was established to compare impression efficacy in conventional orthodontic

periodontal

and single and double implant scenarios.

Results

The overall

RMSE

of digital 3D‑printed models (0.076 9±0.019 5) mm was significantly lower than that of conventional plaster models (0.108 8±0.026 4) mm. In the orthodontic and periodontal groups

the skill gap Δ

was significantly reduced by 55.39% and 46.41%

respectively (

0.01). In the double implant group

the variability of operation time decreased significantly. Multidimensional subjective evaluation showed better patient acceptance and convenience in the digital group (

0.01)

with clinicians preferring tiered digital workflows.

Conclusion

Digital impressions present higher 3D reconstruction accuracy and scenario‑specific experience compensation. They enhance clinical operational stability in orthodontic and periodontal treatments

but have a weaker compensatory effect in complex implant cases. These results provide a practical reference for clinical promotion

multidisciplinary division of labor

and task delegation management.
