A dental implant management system/method that improves communication and coordination between parties associated with dental implant procedures is disclosed. The system/method operates to permit each dental implant professional (DIP) (typically a surgeon, restorative doctor, and dental laboratory) to iteratively generate a patient treatment execution plan (TEP) for the dental implant procedure that is generally structured within execution treatment phases (ETP) and automatically coordinated among each DIP. The ETP typically defines FOUNDATION, IMPLANT PLACEMENT, RESTORATIVE, and MAINTENANCE phases that may each incorporate custom execution phase checklists (EPC) that permit each DIP to ensure that critical elements of their TEP are properly executed. Coordination of the various DIP-generated TEPs is integrated with treatment planning/sequencing, patient scheduling, DIP fee estimation, and dental parts procurement to ensure maximum revenue to each DIP while simultaneously improving the probability of a successful dental implant procedure for the patient.
