Computer aided navigation and interactive teleconsultation in dental implantology

Utilizing advancements in software technology and clinical practicability computer-aided navigation technology is gaining in significance in the field of dental implantology. This presentation is intended to describe the current state or technical development in the field of implant navigation, particularly focusing on practicability, reliability and work-flow in routine clinical application. Technical requirements, potential and limitations of interactive teleconsultation to support the preoperative planning procedure via internet are depicted. A least-squares error algorithm (as inplemented in navigation software) is discussed as a possible approach for improved accuracy control. Computer aided navigation actually proofs to be suitable for practical application and particularly advantageous to comprehensive preoperative planning based on accurate assessment of bone density and structure. The preoperative plan can be realized exactly, avoiding nerve-and teeth- damage. Interactive teleconsultation via internet can provide valuable support especially during the initial phase for surgeons who are not well versed in computer-based planning of implant positions. The accuracy-control algorithm is appropriate to detect systematic registration errors (i.e. mistaken identification of fiducial markers) and cumulative intraoperative errors, but does not separately reflect all components affecting overall quality of system performance.
