Abstract
Bimaxillary immediate full-arch restorations can be prosthodontically, surgically, and esthetically demanding. State-of-the-art computer- assisted guided surgery can significantly improve the predictability and reliability of such procedures while reducing the chair time for the patient. This case report demonstrates how such procedures can be applied using an industrially outsourced service to assist implant planning and treatment preparation. A 63-year-old partially edentulous female with a failing dentition presented at our clinic. After medical assessment and the patient's request to avoid any edentulous episodes during treatment, a digitally guided bimaxillary full-arch reconstruction with an immediate restoration was performed within one session. The surgical and restorative procedures were performed as planned, allowing an immediate provisional restoration. The comparison of the planned and actual implant positions indicated slight inaccuracies between these positions. These deviations did not affect the immediate provisionalization, functionality, or esthetics of the immediate or final prosthetic rehabilitation. Fully digitally guided workflows represent a valuable tool for the efficient and reliable immediate transition from a failing dentition to a fixed reconstruction. The application of an outsourced and assisted digital planning service allows immediate access to digitally guided surgery and can improve efficiency. Deviations between planned and actual implant positions were most likely related to the rotational degrees of freedom around the teeth used for guide retention.
