Abstract
Objective: To analyze the technical accuracy and cost-effectiveness of Digital Light Processing (DLP) and Fused Deposition Modeling (FDM) 3D printing technologies in orthognathic surgery. Methods: An integrative review was conducted through searches in the PubMed, Scopus, and Cochrane Library databases, selecting clinical trials and comparative experimental studies. The evaluated parameters included dimensional accuracy, reduction in operative time, and the economic feasibility of materials and supplies. Results: Virtual surgical planning associated with 3D printing reduced operative time by 40 to 83 minutes and demonstrated FDM using PLA filament proved to be the most mean linear errors below 1.1 mm, fully meeting clinical requirements. While DLP technology provides superior clinical fit for occlusal splints due to its high resolution, it is a viable option for in-house hospital production by significantly reducing material costs. Conclusion: Overall, FDM technology shows potential to democratize access to high-precision surgery due to its exceptional cost-effectiveness. The study is limited by the scarcity of long-term randomized clinical trials directly comparing both technologies regarding soft tissue outcomes.
