Abstract

The aim of this study of native human manibles was to investigate the accuracy of three-dimensional, CT (computer tomography) and CBCT (conebeam tomography) planed positions of dental implants using special radiological and surgical templates. The examination was carried out on 6 native human mandibles, 22 implants (Osseotite®, BIOMET 3i, Palm Beach Gardens, Florida, USA, n=16 / MKII , Nobel Biocare, Zürich, Switzerland, n=6) were placed. After acquiring the radiological image data (CT: Prospeed® SX Power, Fa. GE-Medical Systems, Solingen, Germany, DVT: 3DX Accuitomo®, J. Morita Mfg. Corp., Kyoto, Japan) the tubes contained in the template were used as reference for planing the implant positions with a planning-software (coDiagnostiX®, IVS Solutions AG, Chemnitz, Germany). The tube position was then changed by using a special drilling machine (AME 5®, Dental Labor Jacob GmbH, Marburg, Germany) according to the plan. In this way the radiologic template was converted into a surgical template. After the insertion of the implants CT and CBCT images were acquierd again and then superimposed with the planning data with a special software (VoXim®, IVS Solutions AG, Chemnitz, Germany). Variations in planed and actually implants were measured. The mean deviations referring to the implant base was 1,32mm ± 0,56 and 1,59mm ± 0,67 at the tip of the implant. Mean deviation of implantaxis was 5,69° ± 3,1. The usage of CT data compared to CBCT data revealed no significant difference in accuracy of positioning implants. Accuracy of placing the tubes in the template has no significant effect on accuracy of implantpositions in this study. Overall, the system of three-dimensional dental implantplanning and transferring to the surgical side used in this study seems to be a reliable tool. However, in order to prevent anatomical structures from damage a safe distance of about 2mm should be maintained.
