BACKGROUND
The evidence on the effect of printing orientation on dimensional accuracy and properties of resinous dental models is unclear. This systematic review aimed to assess the impact of printing orientation on the accuracy and properties of additively manufactured resinous dental models, besides the cost, material consumption, and time efficiency at different orientations.
METHODS
A comprehensive web search (PubMed, Scopus, Cochrane) was performed in July 2024 without language restrictions. The included studies were assessed using the modified consort statement for laboratory studies on dental materials. The outcomes were accuracy and surface quality, besides the cost and time efficiency of additively manufactured dental models printed in different directions.
RESULTS
Following PRISMA guidelines, 14 records were included. Most records favored horizontally printed models with minor controversies regarding accuracy, material consumption, time, and cost efficiency. While orientation can influence surface quality, it is often more significantly affected by factors such as the printing technology used, the material properties, and the layer thickness.
CONCLUSIONS
Horizontal orientation has proven to be the most efficient for producing dental models, particularly for single-model manufacturing, due to its superior time and cost savings. However, large-scale and overnight massive production favors the vertical orientation since the platform accommodates twice to triple the models' numbers as horizontal orientation. The majority of studies favor horizontal orientation for its accuracy. Choosing the optimal orientation in additive manufacturing not only ensures precision of dental models, improving the fit of restorations and prostheses, but also leads to significant reductions in production time, material usage, and energy consumption, ultimately minimizing environmental impact.

背景
关于打印方向对树脂牙科模型尺寸精度和性能影响的证据尚不明确。本系统评价旨在评估打印方向对增材制造树脂牙科模型的精度和性能的影响，以及不同方向下的成本、材料消耗和时间效率。
方法
2024年7月进行了全面的网络搜索（PubMed、Scopus、Cochrane），无语言限制。使用针对牙科材料实验室研究的修改后的CONSORT声明对纳入的研究进行评估。除了不同方向打印的增材制造牙科模型的成本和时间效率外，结果还包括精度和表面质量。
结果
按照PRISMA指南，纳入了14条记录。大多数记录支持水平打印的模型，在精度、材料消耗、时间和成本效率方面存在一些小争议。虽然打印方向会影响表面质量，但它通常受所用打印技术、材料性能和层厚等因素的影响更大。
结论
由于水平方向在时间和成本节约方面具有优势，已证明其在生产牙科模型方面最为高效，尤其是对于单模型制造。然而，大规模和夜间大规模生产有利于垂直方向，因为平台容纳的模型数量是水平方向的两倍到三倍。大多数研究因其精度而支持水平方向。在增材制造中选择最佳方向不仅能确保牙科模型的精度，提高修复体和假体的贴合度，还能显著减少生产时间、材料使用和能源消耗，最终将环境影响降至最低。
