Restorative problems with less than desirable implant placement can be challenging. A procedure is presented for the fabrication of a surgical guide stent that dictates placement of dental implants. This surgical guide can enhance implant placement in an efficient and acceptable manner so that final restorations can be properly contoured and esthetic.
OBJECTIVES: To evaluate the magnitude of error in transferring the planned position of implants from reformatted CT scans to a surgical template. METHODS: The deviation between the position of the apex of the proposed implant in paraxial CT reformats and on the corresponding study cast was measured in 77 prospective sites in five maxillas and nine mandibles. RESULTS: The transfer error was 0.6 (s.d. 0.4) mm in the maxilla and 0.3 (s.d. 0.4) mm in the mandible. CONCLUSIONS: The transfer errors detected in this investigation are not clinically relevant. Other factors involved in transferring positional and angular measurements from reformatted CT to the surgical site may result in more significant errors.
The technologic advances in CT made over the last 25 years have made it possible for CT to be an integral component of the dentist's diagnostic armamentarium. CT can be used to image the extent of pathologic conditions as well as help to unravel complex facial fractures. CT can also be used to assess the temporomandibular joints and the paranasal sinuses and for presurgical implant treatment planning. As the speed of image acquisition and reconstruction increases, more dental applications for CT will be realized and requested.
