Szabó Gy., Hrabák К., Gyulai-Gaál, Sz.: 3D CT for planning and contrail of sinus elavation

We have performed 3D CT examinations before and after 21 uniand bilateral sinus elevations, immediately prior to loading of the implants and 1 year after the loading. Comparison of the results with those of panoramic and the customary CT examinations yielded the following useful information.- Any possible difference between planning and performance may be controlled.- The fate of biomaterial implanted in the maxillary sinus was followed.- The 3D CT projections providing most information were established (from a superior position downwards; from lateral and posterior positions forwards).- Possible errors can be discovered before the implant is loaded.- The cases in which it is worthwhile to perform this costly examination were determined: surgical complications, documentation, extensive alveolar atrophy etc.- The results of sinus elevation with different bone substitute materials can readily be compared (e.g. autogenous bone + HTR Bioplant on one side, and autogenous bone + Algipore on the other side).
