In-house (IH) adaptation of these presurgical operations requires compliance with regulatory bodies when designing and manufacturing medical-grade products. The purpose of this study is to evaluate the dimensional accuracy of IH 3D printed orthognathic surgical splints within a hybrid workflow for externally designed splints.Materials and methodsAn in vitro study was conducted utilizing an outsourced (OS) orthognathic surgical splint file from a previously treated patient. The control group included the splint’s original standard tessellation language (STL) file. Experimental groups included: splint (a) milled with zirconia, (b) 3D printed on a Phrozen 4 K (commercial printer), (c) 3D printed on Formlabs 3B+ (Formlabs 3B + have track record of having FDA cleared materials and workflows in dental applications and have potential materials that could be used for IH manufacturing for orthognathic splints upon further testing and FDA clearance). Surface area analysis was performed using 3-Matic (Materialise© Mimics Software) to generate root mean square (RMS) values between digital copies of the splints and their corresponding original STL files.ResultsThe RMS error in equipment processing and analysis was measured at 0.10 mm. Accounting for this error, the 3D-printed splints exhibited an average RMS of 0.20 mm for both the Formlabs 3B + and the Phrozen 4 K. No statistically significant difference was found between splints from different printers or replicas.ConclusionThis study presents a verification process for providers to verify the geometric stability and reproducibility of their IH-printed orthognathic splints (RMS 0.20 mm). Clinicians may find this study useful when crafting a regulatory-compliant process for the IH manufacturing of OS orthognathic surgery splints. | |
