Digital volume tomography (DVT), which enables a three-dimensional (3D) evaluation of available bone, is now regularly performed prior to restoration by means of implant-supported dental prosthetics. The required pre-prosthetic steps can be planned in a target manner according to the “backward planning” concept and on the basis of the envisaged treatment. In principle, there are various approaches to turning a virtual treatment plan into reality. Navigation is a technique in which the 3D position of the drill is continually checked in real time, usually using optical systems, and the correct position and axial inclination can be monitored on a screen in a “chair-side” manner. In addition to navigation-guided implantology, template-guided implantology can also be performed, whereby the information on the pre-planned 3D positioning of an implant is contained in drill sleeves located in a drilling template and implemented by rigid guidance of the drill and implant insertion. In this way, the virtually specified position is transferred to the patient in a reproducible manner. It is important to produce the X‑ray templates, the drill, as well as the drill template using modern 3D printing technology, separately. Computer-assisted implantology is considered to be particularly safe and precise in the case of limited available bone. Both navigated and template-guided implantology achieve the aim of sparing vital structures, reducing post-operative complications, and achieving a functional and esthetically optimal result. Precise planning that takes surgical and prosthetic aspects into consideration has a significant impact on the long-term prognosis in implantology.
