Introduction/Background. Errors can be introduced in implant placement when using stereolithographically manufactured fully limiting surgical guides due to various factors, such as discrepancies designing and manufacturing of (intrinsic error), built-in variations design mechanical components guide systems dimensions (inherent error) or error by the operator (operator error). Aim. The aim this study was evaluate influence factors on position these guides. Materials Methods. Prosthetically-driven positions were planned with pre-operative cone beam computed tomography (CBCT) data digital scans a computer aided (CAD) software. Static guided surgery performed under local anaesthesia mucosa-supported guide. Pre-operative post-operative CBCTs superimposed sleeve reference (N=12). To intrinsic error, standard tessellation language (STL) files virtual STL file obtained after scanning 3D printed stereolithographic superimposed. Inherent calculated geometric model. Results. Intrinsic observed major contributing factor angular deviation implant, linear at shoulder well apex. Operator for mean vertical apex implant. Conclusion. This showed that accuracy largely influenced during compared other sources.
