Methods: Six OOKP patients received a CBCT scan. CBCT scans were performed before and/or between ∼5 and 504 months after the primary OOKP intervention. Preoperative and postoperative results of the CBCT were assessed, regarding the available teeth and to assess the loss of bone in 1 patient, respectively. Resorption of the osteo-odonto-lamina was measured and graded. Five different measurements (I-V) were performed in the coronal and transversal views of CBCT. Results: Four CBCT scans were performed preoperatively and 4 postoperatively. The follow-up time of the patients is between ∼1 to 528 months. Visualization of the potential donor teeth resulted in accurate 3-dimensional visualization of the tooth–lamina–bone complex. CBCT was found to help in the preoperative decision-making process (diameter of optical implant) and in enabling accurate postoperative evaluation of the bone volume and resorption zones of the OOKP. Loss of bone could be measured in a precise range and showed in the completed cases an average loss of 20.2%. Conclusions: The use of CBCT simplifies the preoperative decision making and ordering process. It also helps in determining the postoperative structure and resorption of the prosthesis.
